Two tests supporting development of the launch abort system for the Orion MultiPurpose Crew Vehicle were run in the NASA Ames Unitary Plan wind tunnel last year. The first test used a fully metric model to examine the stability and controllability of the Launch Abort Vehicle during potential abort scenarios for Mach numbers ranging from 0.3 to 2.5. The aerodynamic effects of the Abort Motor and Attitude Control Motor plumes were simulated using high-pressure air flowing through independent paths. The aerodynamic effects of the proximity to the launch vehicle during the early moments of an abort were simulated with a remotely actuated Service Module that allowed the position relative to the Crew Module to be varied appropriately. The second test simulated the acoustic environment around the Launch Abort Vehicle caused by the plumes from the 400,000-pound thrust, solid-fueled Abort Motor. To obtain the proper acoustic characteristics of the hot rocket plumes for the flight vehicle, heated Helium was used. A custom Helium supply system was developed for the test consisting of 2 jumbo high-pressure Helium trailers, a twelve-tube accumulator, and a 13MW gas-fired heater borrowed from the Propulsion Simulation Laboratory at NASA Glenn Research Center. The test provided fluctuating surface pressure measurements at over 200 points on the vehicle surface that have now been used to define the ground-testing requirements for the Orion Launch Abort Vehicle.

First Stage Solid Propellant Multiply Debris Thermal Analysis

NASA Technical Reports Server (NTRS)

Toleman, Benjamin M.

2011-01-01

Destruction of a solid rocket stage of a launch vehicle can create a thermal radiation hazard for an aborting crew module. This hazard was assessed for the Constellation Program (Cx) crew and launch vehicle concept. For this concept, if an abort was initiated in first stage flight, the Crew Module (CM) will separate and be pulled away from the malfunctioning launch vehicle via a Launch Abort System (LAS). Having aborted the mission, the launch vehicle will likely be destroyed via a Flight Termination System (FTS) in order to prevent it from errantly traversing back over land and posing a risk to the public. The resulting launch vehicle debris field, composed primarily of first stage solid propellant, poses a threat to the CM. The harsh radiative thermal environment, caused by surrounding burning propellant debris, may lead to CM parachute failure. A methodology, detailed herein, has been developed to address this concern and to quantify the risk of first stage propellant debris leading to the thermal demise of the CM parachutes. Utilizing basic thermal radiation principles, a software program was developed to calculate parachute temperature as a function of time for a given abort trajectory and debris piece trajectory set. Two test cases, considered worst case aborts with regard to launch vehicle debris environments, were analyzed using the simulation: an abort declared at Mach 1 and an abort declared at maximum dynamic pressure (Max Q). For both cases, the resulting temperature profiles indicated that thermal limits for the parachutes were not exceeded. However, short duration close encounters by single debris pieces did have a significant effect on parachute temperature. Therefore while these two test cases did not indicate exceedance of thermal limits, in order to quantify the risk of parachute failure due to radiative effects from the abort environment, a more thorough probability-based analysis using the methodology demonstrated herein must be performed.

Comparison of Two Recent Launch Abort Platforms

Dittemore, Gary D.; Harding, Adam

2011-01-01

The development of new and safer manned space vehicles is a top priority at NASA. Recently two different approaches of how to accomplish this mission of keeping astronauts safe was successfully demonstrated. With work already underway on an Apollo-like launch abort system for the Orion Crew Exploration Vehicle (CEV), an alternative design concept named the Max Launch Abort System, or MLAS, was developed as a parallel effort. The Orion system, managed by the Constellation office, is based on the design of a single solid launch abort motor in a tower positioned above the capsule. The MLAS design takes a different approach placing the solid launch abort motor underneath the capsule. This effort was led by the NASA Engineering and Safety Center (NESC). Both escape systems were designed with the Ares I Rocket as the launch vehicle and had the same primary requirement to safely propel a crew module away from any emergency event either on the launch pad or during accent. Beyond these two parameters, there was little else in common between the two projects, except that they both concluded in successful launches that will further promote the development of crew launch abort systems. A comparison of these projects from the standpoint of technical requirements; program management and flight test objectives will be done to highlight the synergistic lessons learned by two engineers who worked on each program. This comparison will demonstrate how the scope of the project architecture and management involvement in innovation should be tailored to meet the specific needs of the system under development.

Orion Launch Abort System Performance on Exploration Flight Test 1

NASA Technical Reports Server (NTRS)

McCauley, R.; Davidson, J.; Gonzalez, Guillermo

2015-01-01

This paper will present an overview of the flight test objectives and performance of the Orion Launch Abort System during Exploration Flight Test-1. Exploration Flight Test-1, the first flight test of the Orion spacecraft, was managed and led by the Orion prime contractor, Lockheed Martin, and launched atop a United Launch Alliance Delta IV Heavy rocket. This flight test was a two-orbit, high-apogee, high-energy entry, low-inclination test mission used to validate and test systems critical to crew safety. This test included the first flight test of the Launch Abort System preforming Orion nominal flight mission critical objectives. NASA is currently designing and testing the Orion Multi-Purpose Crew Vehicle (MPCV). Orion will serve as NASA's new exploration vehicle to carry astronauts to deep space destinations and safely return them to earth. The Orion spacecraft is composed of four main elements: the Launch Abort System, the Crew Module, the Service Module, and the Spacecraft Adapter (Fig. 1). The Launch Abort System (LAS) provides two functions; during nominal launches, the LAS provides protection for the Crew Module from atmospheric loads and heating during first stage flight and during emergencies provides a reliable abort capability for aborts that occur within the atmosphere. The Orion Launch Abort System (LAS) consists of an Abort Motor to provide the abort separation from the Launch Vehicle, an Attitude Control Motor to provide attitude and rate control, and a Jettison Motor for crew module to LAS separation (Fig. 2). The jettison motor is used during a nominal launch to separate the LAS from the Launch Vehicle (LV) early in the flight of the second stage when it is no longer needed for aborts and at the end of an LAS abort sequence to enable deployment of the crew module's Landing Recovery System. The LAS also provides a Boost Protective Cover fairing that shields the crew module from debris and the aero-thermal environment during ascent. Although the Orion Program has tested a number of the critical systems of the Orion spacecraft on the ground, the launch environment cannot be replicated completely on Earth. A number of flight tests have been conducted and are planned to demonstrate the performance and enable certification of the Orion Spacecraft. Exploration Flight Test 1, the first flight test of the Orion spacecraft, was successfully flown on December 5, 2014 from Cape Canaveral Air Force Station's Space Launch Complex 37. Orion's first flight was a two-orbit, high-apogee, high-energy entry, low-inclination test mission used to validate and test systems critical to crew safety, such as heat shield performance, separation events, avionics and software performance, attitude control and guidance, parachute deployment and recovery operations. One of the key separation events tested during this flight was the nominal jettison of the LAS. Data from this flight will be used to verify the function of the jettison motor to separate the Launch Abort System from the crew module so it can continue on with the mission. The LAS nominal jettison event on Exploration Flight Test 1 occurred at six minutes and twenty seconds after liftoff (See Fig. 3). The abort motor and attitude control motors were inert for Exploration Flight Test 1, since the mission did not require abort capabilities. A suite of developmental flight instrumentation was included on the flight test to provide data on spacecraft subsystems and separation events. This paper will focus on the flight test objectives and performance of the LAS during ascent and nominal jettison. Selected LAS subsystem flight test data will be presented and discussed in the paper. Exploration Flight Test -1 will provide critical data that will enable engineering to improve Orion's design and reduce risk for the astronauts it will protect as NASA continues to move forward on its human journey to Mars. The lessons learned from Exploration Flight Test 1 and the other Flight Test Vehicles will certainly contribute to the vehicle architecture of a human-rated space launch vehicle.

Optimal control theory determination of feasible return-to-launch-site aborts for the HL-20 Personnel Launch System vehicle

NASA Technical Reports Server (NTRS)

Dutton, Kevin E.

1994-01-01

The personnel launch system (PLS) being studied by NASA is a system to complement the space shuttle and provide alternative access to space. The PLS consists of a manned spacecraft launched by an expendable launch vehicle (ELV). A candidate for the manned spacecraft is the HL-20 lifting body. In the event of an ELV malfunction during the initial portion of the ascent trajectory, the HL-20 will separate from the rocket and perform an unpowered return to launch site (RTLS) abort. This work details an investigation, using optimal control theory, of the RTLS abort scenario. The objective of the optimization was to maximize final altitude. With final altitude as the cost function, the feasibility of an RTLS abort at different times during the ascent was determined. The method of differential inclusions was used to determine the optimal state trajectories, and the optimal controls were then calculated from the optimal states and state rates.

First Stage Solid Propellant Multi Debris Thermal Analysis

NASA Technical Reports Server (NTRS)

Toleman, Benjamin M.

2011-01-01

The crew launch vehicle considered for the Constellation (Cx) Program utilizes a first stage solid rocket motor. If an abort is initiated in first stage flight the Crew Module (CM) will separate and be pulled away from the launch vehicle via a Launch Abort System (LAS) in order to safely and quickly carry the crew away from the malfunction launch vehicle. Having aborted the mission, the launch vehicle will likely be destroyed via a Flight Termination System (FTS) in order to prevent it from errantly traversing back over land and posing a risk to the public. The resulting launch vehicle debris field, composed primarily of first stage solid propellant, poses a threat to the CM. The harsh radiative thermal environment induced by surrounding burning propellant debris may lead to CM parachute failure. A methodology, detailed herein, has been developed to address this concern and quantify the risk of first stage propellant debris leading to radiative thermal demise of the CM parachutes. Utilizing basic thermal radiation principles, a software program was developed to calculate parachute temperature as a function of time for a given abort trajectory and debris piece trajectory set. Two test cases, considered worst-case aborts with regard to launch vehicle debris environments, were analyzed using the simulation: an abort declared at Mach 1 and an abort declared at maximum dynamic pressure (Max Q). For both cases, the resulting temperature profiles indicated that thermal limits for the parachutes were not exceeded. However, short duration close encounters by single debris pieces did have a significant effect on parachute temperature, with magnitudes on the order of 10 s of degrees Fahrenheit. Therefore while these two test cases did not indicate exceedance of thermal limits, in order to quantify the risk of parachute failure due to radiative effects from the abort environment, a more thorough probability-based analysis using the methodology demonstrated herein must be performed.

Orion Abort Flight Test

NASA Technical Reports Server (NTRS)

Hayes, Peggy Sue

2010-01-01

The purpose of NASA's Constellation project is to create the new generation of spacecraft for human flight to the International Space Station in low-earth orbit, the lunar surface, as well as for use in future deep-space exploration. One portion of the Constellation program was the development of the Orion crew exploration vehicle (CEV) to be used in spaceflight. The Orion spacecraft consists of a crew module, service module, space adapter and launch abort system. The crew module was designed to hold as many as six crew members. The Orion crew exploration vehicle is similar in design to the Apollo space capsules, although larger and more massive. The Flight Test Office is the responsible flight test organization for the launch abort system on the Orion crew exploration vehicle. The Flight Test Office originally proposed six tests that would demonstrate the use of the launch abort system. These flight tests were to be performed at the White Sands Missile Range in New Mexico and were similar in nature to the Apollo Little Joe II tests performed in the 1960s. The first flight test of the launch abort system was a pad abort (PA-1), that took place on 6 May 2010 at the White Sands Missile Range in New Mexico. Primary flight test objectives were to demonstrate the capability of the launch abort system to propel the crew module a safe distance away from a launch vehicle during a pad abort, to demonstrate the stability and control characteristics of the vehicle, and to determine the performance of the motors contained within the launch abort system. The focus of the PA-1 flight test was engineering development and data acquisition, not certification. In this presentation, a high level overview of the PA-1 vehicle is given, along with an overview of the Mobile Operations Facility and information on the White Sands tracking sites for radar & optics. Several lessons learned are presented, including detailed information on the lessons learned in the development of wind placards for flight. PA-1 flight data is shown, as well as a comparison of PA-1 flight data to nonlinear simulation Monte Carlo data.

Modeling Powered Aerodynamics for the Orion Launch Abort Vehicle Aerodynamic Database

NASA Technical Reports Server (NTRS)

Chan, David T.; Walker, Eric L.; Robinson, Philip E.; Wilson, Thomas M.

2011-01-01

Modeling the aerodynamics of the Orion Launch Abort Vehicle (LAV) has presented many technical challenges to the developers of the Orion aerodynamic database. During a launch abort event, the aerodynamic environment around the LAV is very complex as multiple solid rocket plumes interact with each other and the vehicle. It is further complicated by vehicle separation events such as between the LAV and the launch vehicle stack or between the launch abort tower and the crew module. The aerodynamic database for the LAV was developed mainly from wind tunnel tests involving powered jet simulations of the rocket exhaust plumes, supported by computational fluid dynamic simulations. However, limitations in both methods have made it difficult to properly capture the aerodynamics of the LAV in experimental and numerical simulations. These limitations have also influenced decisions regarding the modeling and structure of the aerodynamic database for the LAV and led to compromises and creative solutions. Two database modeling approaches are presented in this paper (incremental aerodynamics and total aerodynamics), with examples showing strengths and weaknesses of each approach. In addition, the unique problems presented to the database developers by the large data space required for modeling a launch abort event illustrate the complexities of working with multi-dimensional data.

2016-10-10

Boeing and Aerojet Rocketdyne have begun a series of developmental hot-fire tests with two launch abort engines similar to the ones that will be part of Boeing’s CST-100 Starliner service module, in the Mojave Desert in California. The engines, designed to maximize thrust build-up, while minimizing overshoot during start up, will be fired between half a second and 3 seconds each during the test campaign. If the Starliner’s four launch abort engines were used during an abort scenario, they would fire between 3 and 5.5. seconds, with enough thrust to get the spacecraft and its crew away from the rocket, before splashing down in the ocean under parachutes.

The results are trajectories and main engine cutoff conditions that are approximately the same as for a two SSME case. Requiring the three SSME solution to match the two SSME abort eliminates additional crew training and is accomplished with negligible software impact.

Max Launch Abort System (MLAS) Pad Abort Test Vehicle (PATV) II Attitude Control System (ACS) Integration and Pressurization Subsystem Dynamic Random Vibration Analysis

NASA Technical Reports Server (NTRS)

Ekrami, Yasamin; Cook, Joseph S.

2011-01-01

In order to mitigate catastrophic failures on future generation space vehicles, engineers at the National Aeronautics and Space Administration have begun to integrate a novel crew abort systems that could pull a crew module away in case of an emergency at the launch pad or during ascent. The Max Launch Abort System (MLAS) is a recent test vehicle that was designed as an alternative to the baseline Orion Launch Abort System (LAS) to demonstrate the performance of a "tower-less" LAS configuration under abort conditions. The MLAS II test vehicle will execute a propulsive coast stabilization maneuver during abort to control the vehicles trajectory and thrust. To accomplish this, the spacecraft will integrate an Attitude Control System (ACS) with eight hypergolic monomethyl hydrazine liquid propulsion engines that are capable of operating in a quick pulsing mode. Two main elements of the ACS include a propellant distribution subsystem and a pressurization subsystem to regulate the flow of pressurized gas to the propellant tanks and the engines. The CAD assembly of the Attitude Control System (ACS) was configured and integrated into the Launch Abort Vehicle (LAV) design. A dynamic random vibration analysis was conducted on the Main Propulsion System (MPS) helium pressurization panels to assess the response of the panel and its components under increased gravitational acceleration loads during flight. The results indicated that the panels fundamental and natural frequencies were farther from the maximum Acceleration Spectral Density (ASD) vibrations which were in the range of 150-300 Hz. These values will direct how the components will be packaged in the vehicle to reduce the effects high gravitational loads.

Executive Summary of Propulsion on the Orion Abort Flight-Test Vehicles

The NASA Orion Flight Test Office was tasked with conducting a series of flight tests in several launch abort scenarios to certify that the Orion Launch Abort System is capable of delivering astronauts aboard the Orion Crew Module to a safe environment, away from a failed booster. The first of this series was the Orion Pad Abort 1 Flight-Test Vehicle, which was successfully flown on May 6, 2010 at the White Sands Missile Range in New Mexico. This paper provides a brief overview of the three propulsive subsystems used on the Pad Abort 1 Flight-Test Vehicle. An overview of the propulsive systems originally planned for future flight-test vehicles is also provided, which also includes the cold gas Reaction Control System within the Crew Module, and the Peacekeeper first stage rocket motor encased within the Abort Test Booster aeroshell. Although the Constellation program has been cancelled and the operational role of the Orion spacecraft has significantly evolved, lessons learned from Pad Abort 1 and the other flight-test vehicles could certainly contribute to the vehicle architecture of many future human-rated space launch vehicles.

Application of Fault Management Theory to the Quantitative Selection of a Launch Vehicle Abort Trigger Suite

NASA Technical Reports Server (NTRS)

Lo, Yunnhon; Johnson, Stephen B.; Breckenridge, Jonathan T.

2014-01-01

The theory of System Health Management (SHM) and of its operational subset Fault Management (FM) states that FM is implemented as a "meta" control loop, known as an FM Control Loop (FMCL). The FMCL detects that all or part of a system is now failed, or in the future will fail (that is, cannot be controlled within acceptable limits to achieve its objectives), and takes a control action (a response) to return the system to a controllable state. In terms of control theory, the effectiveness of each FMCL is estimated based on its ability to correctly estimate the system state, and on the speed of its response to the current or impending failure effects. This paper describes how this theory has been successfully applied on the National Aeronautics and Space Administration's (NASA) Space Launch System (SLS) Program to quantitatively estimate the effectiveness of proposed abort triggers so as to select the most effective suite to protect the astronauts from catastrophic failure of the SLS. The premise behind this process is to be able to quantitatively provide the value versus risk trade-off for any given abort trigger, allowing decision makers to make more informed decisions. All current and planned crewed launch vehicles have some form of vehicle health management system integrated with an emergency launch abort system to ensure crew safety. While the design can vary, the underlying principle is the same: detect imminent catastrophic vehicle failure, initiate launch abort, and extract the crew to safety. Abort triggers are the detection mechanisms that identify that a catastrophic launch vehicle failure is occurring or is imminent and cause the initiation of a notification to the crew vehicle that the escape system must be activated. While ensuring that the abort triggers provide this function, designers must also ensure that the abort triggers do not signal that a catastrophic failure is imminent when in fact the launch vehicle can successfully achieve orbit. That is, the abort triggers must have low false negative rates to be sure that real crew-threatening failures are detected, and also low false positive rates to ensure that the crew does not abort from non-crew-threatening launch vehicle behaviors. The analysis process described in this paper is a compilation of over six years of lessons learned and refinements from experiences developing abort triggers for NASA's Constellation Program (Ares I Project) and the SLS Program, as well as the simultaneous development of SHM/FM theory. The paper will describe the abort analysis concepts and process, developed in conjunction with SLS Safety and Mission Assurance (S&MA) to define a common set of mission phase, failure scenario, and Loss of Mission Environment (LOME) combinations upon which the SLS Loss of Mission (LOM) Probabilistic Risk Assessment (PRA) models are built. This abort analysis also requires strong coordination with the Multi-Purpose Crew Vehicle (MPCV) and SLS Structures and Environments (STE) to formulate a series of abortability tables that encapsulate explosion dynamics over the ascent mission phase. The design and assessment of abort conditions and triggers to estimate their Loss of Crew (LOC) Benefits also requires in-depth integration with other groups, including Avionics, Guidance, Navigation and Control(GN&C), the Crew Office, Mission Operations, and Ground Systems. The outputs of this analysis are a critical input to SLS S&MA's LOC PRA models. The process described here may well be the first full quantitative application of SHM/FM theory to the selection of a sensor suite for any aerospace system.

Design of the flight test vehicle (FTV) and pad abort trajectory relied heavily on modeling and simulation including computational fluid dynamics for vehicle aero modeling, 6-degree-of-freedom kinematics models for flight trajectory modeling, and 3-degree-of-freedom kinematics models for parachute force modeling. This paper highlights the simulation techniques and the interaction between the aerodynamics, flight mechanics, and aerodynamic decelerator disciplines during development of the Max Launch Abort System FTV.

Integrated Flight Performance Analysis of a Launch Abort System Concept

NASA Technical Reports Server (NTRS)

Tartabini, Paul V.

2007-01-01

This paper describes initial flight performance analyses conducted early in the Orion Project to support concept feasibility studies for the Crew Exploration Vehicle s Launch Abort System (LAS). Key performance requirements that significantly affect abort capability are presented. These requirements have implications on sizing the Abort Motor, tailoring its thrust profile to meet escape requirements for both launch pad and high drag/high dynamic pressure ascent aborts. Additional performance considerations are provided for the Attitude Control Motor, a key element of the Orion LAS design that eliminates the need for ballast and provides performance robustness over a passive control approach. Finally, performance of the LAS jettison function is discussed, along with implications on Jettison Motor sizing and the timing of the jettison event during a nominal mission. These studies provide an initial understanding of LAS performance that will continue to evolve as the Orion design is matured.

Sensitivity Analysis of Launch Vehicle Debris Risk Model

Gee, Ken; Lawrence, Scott L.

2010-01-01

As part of an analysis of the loss of crew risk associated with an ascent abort system for a manned launch vehicle, a model was developed to predict the impact risk of the debris resulting from an explosion of the launch vehicle on the crew module. The model consisted of a debris catalog describing the number, size and imparted velocity of each piece of debris, a method to compute the trajectories of the debris and a method to calculate the impact risk given the abort trajectory of the crew module. The model provided a point estimate of the strike probability as a function of the debris catalog, the time of abort and the delay time between the abort and destruction of the launch vehicle. A study was conducted to determine the sensitivity of the strike probability to the various model input parameters and to develop a response surface model for use in the sensitivity analysis of the overall ascent abort risk model. The results of the sensitivity analysis and the response surface model are presented in this paper.

Orion Launch Abort System (LAS) Propulsion on Pad Abort 1 (PA-1)

Jones, Daniel S.

2015-01-01

This presentation provides a concise overview of the highly successful Orion Pad Abort 1 (PA-1) flight test, and the three rocket motors that contributed to this success. The primary purpose of the Orion PA-1 flight was to help certify the Orion Launch Abort System (LAS), which can be utilized in the unlikely event of an emergency on the launchpad or during mission vehicle ascent. The PA-1 test was the first fully integrated flight test of the Orion LAS, one of the primary systems within the Orion Multi-Purpose Crew Vehicle (MPCV). The Orion MPCV is part of the architecture within the Space Launch System (SLS), which is being designed to transport astronauts beyond low-Earth orbit for future exploration missions. Had the Orion PA-1 flight abort occurred during launch preparations for a real human spaceflight mission, the PA-1 LAS would have saved the lives of the crew. The PA-1 flight test was largely successful due to the three solid rocket motors of the LAS: the Attitude Control Motor (ACM); the Jettison Motor (JM); and the Abort Motor (AM). All three rocket motors successfully performed their required functions during the Orion PA-1 flight test, flown on May 6, 2010 at the White Sands Missile Range in New Mexico, culminating in a successful demonstration of an abort capability from the launchpad.

NASA s next manned launch platform for missions to the moon and Mars are the Orion and Ares systems. Many critical aspects of the launch system performance are being verified using computational fluid dynamics (CFD) predictions. The Orion Launch Abort Vehicle (LAV) consists of a tower mounted tractor rocket tasked with carrying the Crew Module (CM) safely away from the launch vehicle in the event of a catastrophic failure during the vehicle s ascent. Some of the predictions involving the launch abort system flow fields produced conflicting results, which required further investigation through ground test experiments. Ground tests were performed to acquire data from a hot supersonic jet in cross-flow for the purpose of validating CFD turbulence modeling relevant to the Orion Launch Abort Vehicle (LAV). Both 2-component axial plane Particle Image Velocimetry (PIV) and 3-component cross-stream Stereo Particle Image Velocimetry (SPIV) measurements were obtained on a model of an Abort Motor (AM). Actual flight conditions could not be simulated on the ground, so the highest temperature and pressure conditions that could be safely used in the test facility (nozzle pressure ratio 28.5 and a nozzle temperature ratio of 3) were used for the validation tests. These conditions are significantly different from those of the flight vehicle, but were sufficiently high enough to begin addressing turbulence modeling issues that predicated the need for the validation tests.

Aerodynamic and Aeroacoustic Wind Tunnel Testing of the Orion Spacecraft

Ross, James C.

2011-01-01

The Orion aerodynamic testing team has completed more than 40 tests as part of developing the aerodynamic and loads databases for the vehicle. These databases are key to achieving good mechanical design for the vehicle and to ensure controllable flight during all potential atmospheric phases of a mission, including launch aborts. A wide variety of wind tunnels have been used by the team to document not only the aerodynamics but the aeroacoustic environment that the Orion might experience both during nominal ascents and launch aborts. During potential abort scenarios the effects of the various rocket motor plumes on the vehicle must be accurately understood. The Abort Motor (AM) is a high-thrust, short duration motor that rapidly separates Orion from its launch vehicle. The Attitude Control Motor (ACM), located in the nose of the Orion Launch Abort Vehicle, is used for control during a potential abort. The 8 plumes from the ACM interact in a nonlinear manner with the four AM plumes which required a carefully controlled test to define the interactions and their effect on the control authority provided by the ACM. Techniques for measuring dynamic stability and for simulating rocket plume aerodynamics and acoustics were improved or developed in the course of building the aerodynamic and loads databases for Orion.

The National Aeronautics and Space Administration Orion Flight Test Office was tasked with conducting a series of flight tests in several launch abort scenarios to certify that the Orion Launch Abort System is capable of delivering astronauts aboard the Orion Crew Module to a safe environment, away from a failed booster. The first of this series was the Orion Pad Abort 1 Flight-Test Vehicle, which was successfully flown on May 6, 2010 at the White Sands Missile Range in New Mexico. This report provides a brief overview of the three propulsive subsystems used on the Pad Abort 1 Flight-Test Vehicle. An overview of the propulsive systems originally planned for future flight-test vehicles is also provided, which also includes the cold gas Reaction Control System within the Crew Module, and the Peacekeeper first stage rocket motor encased within the Abort Test Booster aeroshell. Although the Constellation program has been cancelled and the operational role of the Orion spacecraft has significantly evolved, lessons learned from Pad Abort 1 and the other flight-test vehicles could certainly contribute to the vehicle architecture of many future human-rated space launch vehicles

A detailed performance evaluation of the Abort Region Determinator (ARD) module design was provided in support of OFT-1 ascent and OFT-1 intact launch aborts. The evaluation method used compared ARD results against results obtained using the full-up Space Vehicle Dynamic Simulations program under the same conditions. Results were presented for each of the three major ARD math models: (1) the ascent numerical integrator; (2) the mass model, and (3) the second stage predictor as well as the total ARD module. These results demonstrate that the baselined ARD module meets all design objectives for mission control center orbital flight test launch/abort support.

The National Aeronautics and Space Administration (NASA) Engineering and Safety Center (NESC) designed, developed and flew the alternative Max Launch Abort System (MLAS) as risk mitigation for the baseline Orion spacecraft launch abort system (LAS) already in development. The NESC was tasked with both formulating a conceptual objective system (OS) design of this alternative MLAS as well as demonstrating this concept with a simulated pad abort flight test. The goal was to obtain sufficient flight test data to assess performance, validate models/tools, and to reduce the design and development risks for a MLAS OS. Less than 2 years after Project start the MLAS simulated pad abort flight test was successfully conducted from Wallops Island on July 8, 2009. The entire flight test duration was 88 seconds during which time multiple staging events were performed and nine separate critically timed parachute deployments occurred as scheduled. Overall, the as-flown flight performance was as predicted prior to launch. This paper provides an overview of the guidance navigation and control (GN&C) technical approaches employed on this rapid prototyping activity. This paper describes the methodology used to design the MLAS flight test vehicle (FTV). Lessons that were learned during this rapid prototyping project are also summarized.

Calculated maximum Hl ground-level concentrations downwind from launch pad aborts of the space shuttle and Titan 3 C vehicles at Kennedy Space Center

NASA Technical Reports Server (NTRS)

Dumbauld, R. K.; Bjorklund, J. R.

1972-01-01

A quantitative assessment is described of the potential environmental hazard posed by the atmospheric release of HCl resulting from the burning of solid propellant during two hypothetical on-pad aborts of the Titan 3 C and space shuttle vehicles at Kennedy Space Center. In one pad-abort situation, it is assumed that the cases of the two solid-propellant engines are ruptured and the burning propellant falls to the ground in the immediate vicinity of the launch pad where it continues to burn for 5 minutes. In the other pad-abort situation considered, one of the two solid engines on each vehicle is assumed to ignite and burn at the normal rate while the vehicle remains on the launch pad. Calculations of maximum HCl ground-level concentration for the above on-pad abort situations were made using the computerized NASA/MSFC multilayer diffusion models in conjunction with appropriate meteorological and source inputs. Three meteorological regimes are considered-fall, spring, and afternoon sea-breeze. Source inputs for the hazard calculations were developed. The principal result of the calculations is that maximum ground-level HCl concentrations at distances greater than 1 kilometer from the launch pad are less than 3 parts per million in all cases considered.

Overview of C/C-SiC Composite Development for the Orion Launch Abort System

2012-01-01

Past and present efforts by the authors to further understanding of the ceramic matrix composite (CMC) material used in the valve components of the Orion Launch Abort System (LAS) Attitude Control Motor (ACM) will be presented. The LAS is designed to quickly lift the Orion Crew Exploration Vehicle (CEV) away from its launch vehicle in emergency abort scenarios. The ACM is a solid rocket motor which utilizes eight throttleable nozzles to maintain proper orientation of the CEV during abort operations. Launch abort systems have not been available for use by NASA on manned launches since the last Apollo ]Saturn launch in 1975. The CMC material, carbon-carbon/silicon-carbide (C/C-SiC), is manufactured by Fiber Materials, Inc. and consists of a rigid 4-directional carbon-fiber tow weave reinforced with a mixed carbon plus SiC matrix. Several valve and full system (8-valve) static motor tests have been conducted by the motor vendor. The culmination of these tests was the successful flight test of the Orion LAS Pad Abort One (PA ]1) vehicle on May 6, 2010. Due to the fast pace of the LAS development program, NASA Marshall Space Flight Center assisted the LAS community by performing a series of material and component evaluations using fired hardware from valve and full ]system development motor tests, and from the PA-1 flight ACM motor. Information will be presented on the structure of the C/C-SiC material, as well as the efficacy of various non ]destructive evaluation (NDE) techniques, including but not limited to: radiography, computed tomography, nanofocus computed tomography, and X-ray transmission microscopy. Examinations of the microstructure of the material via scanning electron microscopy and energy dispersive spectroscopy will also be discussed. The findings resulting from the subject effort are assisting the LAS Project in risk assessments and in possible modifications to the final ACM operational design.

Pitch Guidance Optimization for the Orion Abort Flight Tests

NASA Technical Reports Server (NTRS)

Stillwater, Ryan Allanque

2010-01-01

The National Aeronautics and Space Administration created the Constellation program to develop the next generation of manned space vehicles and launch vehicles. The Orion abort system is initiated in the event of an unsafe condition during launch. The system has a controller gains schedule that can be tuned to reduce the attitude errors between the simulated Orion abort trajectories and the guidance trajectory. A program was created that uses the method of steepest descent to tune the pitch gains schedule by an automated procedure. The gains schedule optimization was applied to three potential abort scenarios; each scenario tested using the optimized gains schedule resulted in reduced attitude errors when compared to the Orion production gains schedule.

CAPE CANAVERAL, Fla. – Inside the Launch Abort System Facility at NASA’s Kennedy Space Center in Florida, a crane brings the fourth and final Ogive panel closer for installation on Orion's Launch Abort System. The panels will smooth the airflow over the conical spacecraft to limit sound and vibration, which will make for a much smoother ride for the astronauts who will ride inside Orion in the future. The work marked the final major assembly steps for the spacecraft before it is transported to Space Launch Complex 37 at Cape Canaveral Air Force Station in November. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted flight test of Orion is scheduled to launch in December 2014 atop a United Launch Alliance Delta IV Heavy rocket, and in 2018 on NASA’s Space Launch System rocket.

Space Shuttle Abort Evolution

NASA Technical Reports Server (NTRS)

Henderson, Edward M.; Nguyen, Tri X.

2011-01-01

This paper documents some of the evolutionary steps in developing a rigorous Space Shuttle launch abort capability. The paper addresses the abort strategy during the design and development and how it evolved during Shuttle flight operations. The Space Shuttle Program made numerous adjustments in both the flight hardware and software as the knowledge of the actual flight environment grew. When failures occurred, corrections and improvements were made to avoid a reoccurrence and to provide added capability for crew survival. Finally some lessons learned are summarized for future human launch vehicle designers to consider.

Aerodynamic Testing of the Orion Launch Abort Tower Separation with Jettison Motor Jet Interactions

NASA Technical Reports Server (NTRS)

Rhode, Matthew N.; Chan, David T.; Niskey, Charles J.; Wilson, Thomas M.

2011-01-01

The aerodynamic database for the Orion Launch Abort System (LAS) was developed largely from wind tunnel tests involving powered jet simulations of the rocket exhaust plumes, supported by computational fluid dynamics (CFD) simulations. The LAS contains three solid rocket motors used in various phases of an abort to provide propulsion, steering, and Launch Abort Tower (LAT) jettison from the Crew Module (CM). This paper describes a pair of wind tunnel experiments performed at transonic and supersonic speeds to determine the aerodynamic effects due to proximity and jet interactions during LAT jettison from the CM at the end of an abort. The tests were run using two different scale models at angles of attack from 150deg to 200deg , sideslip angles from -10deg to +10deg , and a range of powered thrust levels from the jettison motors to match various jet simulation parameters with flight values. Separation movements between the CM and LAT included axial and vertical translations as well as relative pitch angle between the two bodies. The paper details aspects of the model design, nozzle scaling methodology, instrumentation, testing procedures, and data reduction. Sample data are shown to highlight trends seen in the results.

Testing Strategies and Methodologies for the Max Launch Abort System

NASA Technical Reports Server (NTRS)

Schaible, Dawn M.; Yuchnovicz, Daniel E.

2011-01-01

The National Aeronautics and Space Administration (NASA) Engineering and Safety Center (NESC) was tasked to develop an alternate, tower-less launch abort system (LAS) as risk mitigation for the Orion Project. The successful pad abort flight demonstration test in July 2009 of the "Max" launch abort system (MLAS) provided data critical to the design of future LASs, while demonstrating the Agency s ability to rapidly design, build and fly full-scale hardware at minimal cost in a "virtual" work environment. Limited funding and an aggressive schedule presented a challenge for testing of the complex MLAS system. The successful pad abort flight demonstration test was attributed to the project s systems engineering and integration process, which included: a concise definition of, and an adherence to, flight test objectives; a solid operational concept; well defined performance requirements, and a test program tailored to reducing the highest flight test risks. The testing ranged from wind tunnel validation of computational fluid dynamic simulations to component ground tests of the highest risk subsystems. This paper provides an overview of the testing/risk management approach and methodologies used to understand and reduce the areas of highest risk - resulting in a successful flight demonstration test.

Launch Vehicle Failure Dynamics and Abort Triggering Analysis

NASA Technical Reports Server (NTRS)

Hanson, John M.; Hill, Ashely D.; Beard, Bernard B.

2011-01-01

Launch vehicle ascent is a time of high risk for an on-board crew. There are many types of failures that can kill the crew if the crew is still on-board when the failure becomes catastrophic. For some failure scenarios, there is plenty of time for the crew to be warned and to depart, whereas in some there is insufficient time for the crew to escape. There is a large fraction of possible failures for which time is of the essence and a successful abort is possible if the detection and action happens quickly enough. This paper focuses on abort determination based primarily on data already available from the GN&C system. This work is the result of failure analysis efforts performed during the Ares I launch vehicle development program. Derivation of attitude and attitude rate abort triggers to ensure that abort occurs as quickly as possible when needed, but that false positives are avoided, forms a major portion of the paper. Some of the potential failure modes requiring use of these triggers are described, along with analysis used to determine the success rate of getting the crew off prior to vehicle demise.

Flight-Simulated Launch-Pad-Abort-to-Landing Maneuvers for a Lifting Body

NASA Technical Reports Server (NTRS)

Jackson, E. Bruce; Rivers, Robert A.

1998-01-01

The results of an in-flight investigation of the feasibility of conducting a successful landing following a launch-pad abort of a vertically-launched lifting body are presented. The study attempted to duplicate the abort-to-land-ing trajectory from the point of apogee through final flare and included the steep glide and a required high-speed, low-altitude turn to the runway heading. The steep glide was flown by reference to ground-provided guidance. The low-altitude turn was flown visually with a reduced field- of-view duplicating that of the simulated lifting body. Results from the in-flight experiment are shown to agree with ground-based simulation results; however, these tests should not be regarded as a definitive due to performance and control law dissimilarities between the two vehicles.

The Orion Pad Abort 1 (PA-1) Flight Test: A Propulsion Success

NASA Technical Reports Server (NTRS)

Jones, Daniel S.

2015-01-01

This poster provides a concise overview of the highly successful Orion Pad Abort 1 (PA-1) flight test, and the three rocket motors that contributed to this success. The primary purpose of the Orion PA-1 flight was to help certify the Orion Launch Abort System (LAS), which can be utilized in the unlikely event of an emergency on the launchpad or during mission vehicle ascent. The PA-1 test was the first fully integrated flight test of the Orion LAS, one of the primary systems within the Orion Multi-Purpose Crew Vehicle (MPCV). The Orion MPCV is part of the architecture within the Space Launch System (SLS), which is being designed to transport astronauts beyond low-Earth orbit for future exploration missions. Had the Orion PA-1 flight abort occurred during launch preparations for a real human spaceflight mission, the PA-1 LAS would have saved the lives of the crew. The PA-1 flight test was largely successful due to the three solid rocket motors of the LAS: the Attitude Control Motor (ACM); the Jettison Motor (JM); and the Abort Motor (AM). All three rocket motors successfully performed their required functions during the Orion PA-1 flight test, flown on May 6, 2010 at the White Sands Missile Range in New Mexico, culminating in a successful demonstration of an abort capability from the launchpad.

This paper describes the process used to generate the large number of configurations and suggests ways to further automate the process and make it more efficient for future studies. The design geometry for this study is the launch abort system of the NASA Crew Launch Vehicle.

Reverse Launch Abort System Parachute Architecture Trade Study

NASA Technical Reports Server (NTRS)

Litton, Daniel K.; O'Keefe, Stephen A.; Winski, Richard G.

2011-01-01

This study investigated a potential Launch Abort System (LAS) Concept of Operations and abort parachute architecture. The purpose of the study was to look at the concept of jettisoning the LAS tower forward (Reverse LAS or RLAS) into the free-stream flow rather than after reorienting to a heatshield forward orientation. A hypothesized benefit was that due to the compressed timeline the dynamic pressure at main line stretch would be substantially less. This would enable the entry parachutes to be designed and sized based on entry loading conditions rather than the current stressing case of a Pad Abort. Ultimately, concerns about the highly dynamic reorientation of the CM via parachutes, and the additional requirement of a triple bridle attachment for the RLAS parachute system, overshadowed the potential benefits and ended this effort.

Orion Guidance and Control Ascent Abort Algorithm Design and Performance Results

NASA Technical Reports Server (NTRS)

Proud, Ryan W.; Bendle, John R.; Tedesco, Mark B.; Hart, Jeremy J.

2009-01-01

During the ascent flight phase of NASA s Constellation Program, the Ares launch vehicle propels the Orion crew vehicle to an agreed to insertion target. If a failure occurs at any point in time during ascent then a system must be in place to abort the mission and return the crew to a safe landing with a high probability of success. To achieve continuous abort coverage one of two sets of effectors is used. Either the Launch Abort System (LAS), consisting of the Attitude Control Motor (ACM) and the Abort Motor (AM), or the Service Module (SM), consisting of SM Orion Main Engine (OME), Auxiliary (Aux) Jets, and Reaction Control System (RCS) jets, is used. The LAS effectors are used for aborts from liftoff through the first 30 seconds of second stage flight. The SM effectors are used from that point through Main Engine Cutoff (MECO). There are two distinct sets of Guidance and Control (G&C) algorithms that are designed to maximize the performance of these abort effectors. This paper will outline the necessary inputs to the G&C subsystem, the preliminary design of the G&C algorithms, the ability of the algorithms to predict what abort modes are achievable, and the resulting success of the abort system. Abort success will be measured against the Preliminary Design Review (PDR) abort performance metrics and overall performance will be reported. Finally, potential improvements to the G&C design will be discussed.

Tobias, Mark; Sauvageau, Donald R.; Hines, Mark; Geiser, Norman L.; Cash, Steve (Technical Monitor)

2002-01-01

The Five Segment Booster (FSB) concept has been evolving for a number of years as a means to enhance the overall safety and reliability of the Space Shuttle system by minimizing the need to fly the more challenging Return to Launch Site (RTLS) and Transoceanic Abort Landing (TAL) abort profiles. The initial evaluation of the FSB concept was conducted in 1996 to determine the feasibility of the FSB in achieving transatlantic abort leading TAL from the pad, thus eliminating the return to launch site (RTLS) abort mode. The initial study was conducted by ATK Thiokol and did show the potential for the FSB to eliminate the RTLS abort mode. Later Rockwell (now Boeing) conducted a similar study utilizing FSB performance characteristics and verified that the FSB could indeed achieve TAL from the pad, thereby eliminating the necessity for the RTLS abort. The purpose of this paper is to discuss the details of the enhancements achieved through the internally funded study conducted by Boeing and ATK Thiokol. To better understand the enhancements that were addressed as part of this follow-on study, some background on what was achieved in the Phase A study is appropriate.

Approaches to Improve the Performances of the Sea Launch System Performances

NASA Astrophysics Data System (ADS)

Tatarevs'kyy, K.

2002-01-01

The paper dwells on the outlines of the techniques of on-line pre-launch analysis on possibility of safe and reliable LV launch off floating launch system, when actual launch conditions (weather, launcher motion parameters) are beyond design limitations. The technique guarantees to follow the take-off LV trajectory limitations (the shock-free launch) and allows the improvement of the operat- ing characteristics of the floating launch systems at the expense of possibility to authorize the launch even if a number of weather and launcher motion parameters restrictions are exceeded. This paper ideas are applied for LV of Zenit-type launches off tilting launch platform, operative within Sea Launch. The importance, novelty and urgency of the approach under consideration is explained by the fact that the application during floating launch systems operation allows the bringing down of the num- ber of weather-conditioned launch abort cases. And this, in its part, increases the trustworthiness of the mission fulfillment on specific spacecraft injection, since, in the long run, the launch abort may cause the crossing of allowable wait threshold and accordingly the mission abort. All previous launch kinds for these LV did not require the development of the special technique of pre-launch analysis on launch possibility, since weather limitations for stationary launcher condi- tions are basically reduced to the wind velocity limitations. This parameter is reliably monitored and is sure to influence the launch dynamics. So the measured wind velocity allows the thorough picture on the possibility of the launch off the ground-based launcher. Since the floating launch systems commit complex and continuous movements under the exposure of the wind and the waves, the number of parameters is increased and, combined differently, they do not always make the issue on shockless launch critical. The proposed technique of the pre-launch analysis of the forthcoming launch dynamics with the consideration of the launch conditions (weather, launcher motion parameters, actual LV and carried SC performance) allow the evaluation of the actual combination of launch environment influence on the possibility of shockless launch. On the basis of the analysis the launch permissibility deci- sion is taken, even if some separate parameters are beyond the design range.

Open-Loop Pitch Table Optimization for the Maximum Dynamic Pressure Orion Abort Flight Test

NASA Technical Reports Server (NTRS)

Stillwater, Ryan A.

2009-01-01

NASA has scheduled the retirement of the space shuttle orbiter fleet at the end of 2010. The Constellation program was created to develop the next generation of human spaceflight vehicles and launch vehicles, known as Orion and Ares respectively. The Orion vehicle is a return to the capsule configuration that was used in the Mercury, Gemini, and Apollo programs. This configuration allows for the inclusion of an abort system that safely removes the capsule from the booster in the event of a failure on launch. The Flight Test Office at NASA's Dryden Flight Research Center has been tasked with the flight testing of the abort system to ensure proper functionality and safety. The abort system will be tested in various scenarios to approximate the conditions encountered during an actual Orion launch. Every abort will have a closed-loop controller with an open-loop backup that will direct the vehicle during the abort. In order to provide the best fit for the desired total angle of attack profile with the open-loop pitch table, the table is tuned using simulated abort trajectories. A pitch table optimization program was created to tune the trajectories in an automated fashion. The program development was divided into three phases. Phase 1 used only the simulated nominal run to tune the open-loop pitch table. Phase 2 used the simulated nominal and three simulated off nominal runs to tune the open-loop pitch table. Phase 3 used the simulated nominal and sixteen simulated off nominal runs to tune the open-loop pitch table. The optimization program allowed for a quicker and more accurate fit to the desired profile as well as allowing for expanded resolution of the pitch table.

The Space Shuttle is an advanced manned launch system with a respectable history of service and a demonstrated level of safety. Recent studies have shown that the Space Shuttle has a relatively low probability of having a failure that is instantaneously catastrophic during nominal flight as compared with many US and international launch systems. However, since the Space Shuttle is a manned. system, a number of mission abort contingencies exist to primarily ensure the safety of the crew during off-nominal situations and to attempt to maintain the integrity of the Orbiter. As the Space Shuttle ascends to orbit it transverses various intact abort regions evaluated and planned before the flight to ensure that the Space Shuttle Orbiter, along with its crew, may be returned intact either to the original launch site, a transoceanic landing site, or returned from a substandard orbit. An intact abort may be initiated due to a number of system failures but the highest likelihood and most challenging abort scenarios are initiated by a premature shutdown of a Space Shuttle Main Engine (SSME). The potential consequences of such a shutdown vary as a function of a number of mission parameters but all of them may be related to mission time for a specific mission profile. This paper focuses on the Dynamic Abort Risk Evaluation (DARE) model process, applications, and its capability to evaluate the risk of Loss Of Vehicle (LOV) due to the complex systems interactions that occur during Space Shuttle intact abort scenarios. In addition, the paper will examine which of the Space Shuttle subsystems are critical to ensuring a successful return of the Space Shuttle Orbiter and crew from such a situation.

Design and Analysis of Outer Mold Line Close-outs for the Max Launch Abort System (MLAS) Flight Experiment

Woods-Vedeler, Jessica A.; Knutson, Jeffrey R.; Schuster, David M.; Tyler, Erik D.

2010-01-01

In 2007, the NASA Exploration Systems Mission Directorate (ESMD) chartered the NASA Engineering Safety Center (NESC) to demonstrate an alternate launch abort concept as risk mitigation for the Orion project's baseline "tower" design. On July 8, 2009, a full scale, passive aerodynamically stabilized Max Launch Abort System (MLAS) pad abort demonstrator was successfully launched from NASA Goddard Space Flight Center's Wallops Flight Facility. Aerodynamic close-outs were required to cover openings on the MLAS fairing to prevent aerodynamic flow-through and to maintain the MLAS OML surface shape. Two-ply duct tape covers were designed to meet these needs. The duct tape used was a high strength fiber reinforced duct tape with a rubberized adhesive that demonstrated 4.6 lb/in adhesion strength to the unpainted fiberglass fairing. Adhesion strength was observed to increase as a function of time. The covers were analyzed and experimentally tested to demonstrate their ability to maintain integrity under anticipated vehicle ascent pressure loads and to not impede firing of the drogue chute mortars. Testing included vacuum testing and a mortar fire test. Tape covers were layed-up on thin Teflon sheets to facilitate installation on the vehicle. Custom cut foam insulation board was used to fill mortar hole and separation joint cavities and provide support to the applied tape covers. Flight test results showed that the tape covers remained adhered during flight.

A Proposed Ascent Abort Flight Test for the Max Launch Abort System

Tartabini, Paul V.; Gilbert, Michael G.; Starr, Brett R.

2016-01-01

The NASA Engineering and Safety Center initiated the Max Launch Abort System (MLAS) Project to investigate alternate crew escape system concepts that eliminate the conventional launch escape tower by integrating the escape system into an aerodynamic fairing that fully encapsulates the crew capsule and smoothly integrates with the launch vehicle. This paper proposes an ascent abort flight test for an all-propulsive towerless escape system concept that is actively controlled and sized to accommodate the Orion Crew Module. The goal of the flight test is to demonstrate a high dynamic pressure escape and to characterize jet interaction effects during operation of the attitude control thrusters at transonic and supersonic conditions. The flight-test vehicle is delivered to the required test conditions by a booster configuration selected to meet cost, manufacturability, and operability objectives. Data return is augmented through judicious design of the boost trajectory, which is optimized to obtain data at a range of relevant points, rather than just a single flight condition. Secondary flight objectives are included after the escape to obtain aerodynamic damping data for the crew module and to perform a high-altitude contingency deployment of the drogue parachutes. Both 3- and 6-degree-of-freedom trajectory simulation results are presented that establish concept feasibility, and a Monte Carlo uncertainty assessment is performed to provide confidence that test objectives can be met.

Boeing’s CST-100 Pad Abort Test Vehicle is almost ready to head to White Sands, New Mexico, to test the launch abort engines. During that test, the four abort engines will prove that the vehicle can safely perform an abort maneuver in the event of an emergency on the launchpad or during flight. The vehicle is mated to the service module for a fit check, and then the two will be taken apart for final preparations before heading to the desert.

Crew Exploration Vehicle Launch Abort Controller Performance Analysis

Sparks, Dean W., Jr.; Raney, David L.

2007-01-01

This paper covers the simulation and evaluation of a controller design for the Crew Module (CM) Launch Abort System (LAS), to measure its ability to meet the abort performance requirements. The controller used in this study is a hybrid design, including features developed by the Government and the Contractor. Testing is done using two separate 6-degree-of-freedom (DOF) computer simulation implementations of the LAS/CM throughout the ascent trajectory: 1) executing a series of abort simulations along a nominal trajectory for the nominal LAS/CM system; and 2) using a series of Monte Carlo runs with perturbed initial flight conditions and perturbed system parameters. The performance of the controller is evaluated against a set of criteria, which is based upon the current functional requirements of the LAS. Preliminary analysis indicates that the performance of the present controller meets (with the exception of a few cases) the evaluation criteria mentioned above.

Effects of the Orion Launch Abort Vehicle Plumes on Aerodynamics and Controllability

2013-01-01

Characterization of the launch abort system of the Multi-purpose Crew Vehicle (MPCV) for control design and accurate simulation has provided a significant challenge to aerodynamicists and design engineers. The design space of the launch abort vehicle (LAV) includes operational altitudes from ground level to approximately 300,000 feet, Mach numbers from 0-9, and peak dynamic pressure near 1300psf during transonic flight. Further complicating the characterization of the aerodynamics and the resultant vehicle controllability is the interaction of the vehicle flowfield with the plumes of the two solid propellant motors that provide attitude control and the main propulsive impulse for the LAV. These interactions are a function of flight parameters such as Mach number, altitude, dynamic pressure, vehicle attitude, as well as parameters relating to the operation of the motors themselves - either as a function of time for the AM, or as a result of the flight control system requests for control torque from the ACM. This paper discusses the computational aerodynamic modeling of the aerodynamic interaction caused by main abort motor and the attitude control motor of the MPCV LAV, showing the effects of these interactions on vehicle controllability.

The Crew Exploration Vehicle (CEV) is required to maintain continuous abort capability from lift off through destination arrival. This requirement is driven by the desire to provide the capability to safely return the crew to Earth after failure scenarios during the various phases of the mission. This paper addresses abort trajectory design considerations, concept of operations and guidance algorithm prototypes for the portion of the ascent trajectory following nominal jettison of the Launch Abort System (LAS) until safe orbit insertion. Factors such as abort system performance, crew load limits, natural environments, crew recovery, and vehicle element disposal were investigated to determine how to achieve continuous vehicle abort capability.

One of the primary design drivers for NASA's Crew Exploration Vehicle (CEV) is to ensure crew safety. Aborts during the critical ascent flight phase require the design and operation of CEV systems to escape from the Crew Launch Vehicle and return the crew safely to the Earth. To accomplish this requirement of continuous abort coverage, CEV ascent abort modes are being designed and analyzed to accommodate the velocity, altitude, atmospheric, and vehicle configuration changes that occur during ascent. The analysis involves an evaluation of the feasibility and survivability of each abort mode and an assessment of the abort mode coverage. These studies and design trades are being conducted so that more informed decisions can be made regarding the vehicle abort requirements, design, and operation. This paper presents an overview of the CEV, driving requirements for abort scenarios, and an overview of current ascent abort modes. Example analysis results are then discussed. Finally, future areas for abort analysis are addressed.

Owens, Donald B.; Aibicjpm. Vamessa V.

2011-01-01

With the retirement of the Space Shuttle, NASA is designing a new spacecraft, called Orion, to fly astronauts to low earth orbit and beyond. Characterization of the dynamic stability of the Orion spacecraft is important for the design of the spacecraft and trajectory construction. Dynamic stability affects the stability and control of the Orion Crew Module during re-entry, especially below Mach = 2.0 and including flight under the drogues. The Launch Abort Vehicle is affected by dynamic stability as well, especially during the re-orientation and heatshield forward segments of the flight. The dynamic stability was assessed using the forced oscillation technique, free-to-oscillate, ballistic range, and sub-scale free-flight tests. All of the test techniques demonstrated that in heatshield-forward flight the Crew Module and Launch Abort Vehicle are dynamically unstable in a significant portion of their flight trajectory. This paper will provide a brief overview of the Orion dynamic aero program and a high-level summary of the dynamic stability characteristics of the Orion spacecraft.

May 28 International Day of Action for Women's Health.

PubMed

1993-01-01

The 1993 Day of Action for Women's Health focused on the number of deaths which occur as a result of unsafe and illegal abortion. In Argentina, a signature campaign to support decriminalization of abortion enlisted the aid of more than 100 influential citizens. The campaign in Brazil coincided with the introduction of reforms which would decriminalize abortion. In Chile, a nationwide campaign was launched to reinstate therapeutic abortion. The day was commemorated in Colombia with several events which advocated the decriminalization of abortion. Women in Costa Rica demanded being treated as subjects, not objects, of health policies, while Ecuadorian activists spent the day distributing an article analyzing the importance of the day and discussing the health problems of Ecuadorian women, especially those related to overwork, subordinate status, and illegal abortion. A new study was released in Mexico which revealed that four women die every day of pregnancy and child-birth related causes (40% of these are the complications of induced abortion). Nationwide activities were coordinated in Nicaragua including forums, theater presentations, festivals, and a women's march. A labor group joined the campaign in Peru, and efforts in Puerto Rico centered on preventing and surviving breast cancer. Elsewhere in the world, genital mutilation was the topic of a seminar in Canada, women in the Philippines launched a campaign against "needless" maternal mortality, and a Spanish group issued a publication analyzing abortion around the world and discussing the introduction of RU-486 to Spain. The next important date is September 28, when women's health groups in Latin America and the Caribbean will join to call for the legalization of abortion.

Launch Vehicle Debris Models and Crew Vehicle Ascent Abort Risk

NASA Technical Reports Server (NTRS)

Gee, Ken; Lawrence, Scott

2013-01-01

For manned space launch systems, a reliable abort system is required to reduce the risks associated with a launch vehicle failure during ascent. Understanding the risks associated with failure environments can be achieved through the use of physics-based models of these environments. Debris fields due to destruction of the launch vehicle is one such environment. To better analyze the risk posed by debris, a physics-based model for generating launch vehicle debris catalogs has been developed. The model predicts the mass distribution of the debris field based on formulae developed from analysis of explosions. Imparted velocity distributions are computed using a shock-physics code to model the explosions within the launch vehicle. A comparison of the debris catalog with an existing catalog for the Shuttle external tank show good comparison in the debris characteristics and the predicted debris strike probability. The model is used to analyze the effects of number of debris pieces and velocity distributions on the strike probability and risk.

Time Accurate CFD Simulations of the Orion Launch Abort Vehicle in the Transonic Regime

NASA Technical Reports Server (NTRS)

Ruf, Joseph; Rojahn, Josh

2011-01-01

Significant asymmetries in the fluid dynamics were calculated for some cases in the CFD simulations of the Orion Launch Abort Vehicle through its abort trajectories. The CFD simulations were performed steady state with symmetric boundary conditions and geometries. The trajectory points at issue were in the transonic regime, at 0 and 5 angles of attack with the Abort Motors with and without the Attitude Control Motors (ACM) firing. In some of the cases the asymmetric fluid dynamics resulted in aerodynamic side forces that were large enough that would overcome the control authority of the ACMs. MSFC s Fluid Dynamics Group supported the investigation into the cause of the flow asymmetries with time accurate CFD simulations, utilizing a hybrid RANS-LES turbulence model. The results show that the flow over the vehicle and the subsequent interaction with the AB and ACM motor plumes were unsteady. The resulting instantaneous aerodynamic forces were oscillatory with fairly large magnitudes. Time averaged aerodynamic forces were essentially symmetric.

Mathias, Donovan L.; Lawrence, Scott L.

2006-01-01

A study was performed to assess the effect of booster configuration on the ascent abort process. A generic abort event sequence was created and booster related risk drivers were identified. Three model boosters were considered in light of the risk drivers: a solid rocket motor configuration, a side mount combination solid and liquid configuration, and a stacked liquid configuration. The primary risk drivers included explosive fireball, overpressure, and fragment effects and booster-crew module re-contact. Risk drivers that were not specifically booster dependent were not addressed. The solid rocket configuration had the most benign influence on an abort while the side mount architecture provided the most challenging abort environment.

2013-05-01

In June 2012, a new abortion law came into effect in Rwanda as part of a larger review of Rwanda's penal code. This was a significant step in a country where it was previously taboo even to discuss abortion. This article describes some of the crucial elements in how this success was achieved in Rwanda, which began through a project launched by Rutgers WPF on "sensitive issues in young people's sexuality" in several countries. This paper describes how the Rwandan Youth Action Movement decided to work on unsafe abortion as part of this project. They gathered data on the extent of unsafe abortion and testimonies of young Rwandan women in prison for abortions; organized debates, values clarification exercises, interviews and a survey in four universities; launched a petition for law reform; produced awareness-raising materials; worked with the media; and met with representatives from government ministries, the national women's and youth councils, and parliamentarians - all of which played a significant role in the advocacy process for amendment of the law, which was revised when the penal code came up for review in June 2012. This history shows how important the role of young people can be in producing change and exposes, through personal stories, the need for a better abortion law, not only in Rwanda but also elsewhere.

The tests could be instrumental in developing the first crew launch escape system in almost 30 years. Paving the way for a series of integrated PAD test flights, the engine tests support development of a system that could pull a crew safely away from danger during liftoff. A series of 16 hot fire tests of a 50,000-pound thrust RS-88 rocket engine were conducted, resulting in a total of 55 seconds of successful engine operation. The engine is being developed by the Rocketdyne Propulsion and Power unit of the Boeing Company. Integrated launch abort demonstration tests in 2005 will use four RS-88 engines to separate a test vehicle from a test platform, simulating pulling a crewed vehicle away from an aborted launch. Four 156-foot parachutes will deploy and carry the vehicle to landing. Lockheed Martin is building the vehicles for the PAD tests. Seven integrated tests are plarned for 2005 and 2006.

Abort performance for a winged-body single-stage to orbit vehicle. M.S. Thesis - George Washington Univ.

Lyon, Jeffery A.

1995-01-01

Optimal control theory is employed to determine the performance of abort to orbit (ATO) and return to launch site (RTLS) maneuvers for a single-stage to orbit vehicle. The vehicle configuration examined is a seven engine, winged-body vehicle, that lifts-off vertically and lands horizontally. The abort maneuvers occur as the vehicle ascends to orbit and are initiated when the vehicle suffers an engine failure. The optimal control problems are numerically solved in discretized form via a nonlinear programming (NLP) algorithm. A description highlighting the attributes of this NLP method is provided. ATO maneuver results show that the vehicle is capable of ascending to orbit with a single engine failure at lift-off. Two engine out ATO maneuvers are not possible from the launch pad, but are possible after launch when the thrust to weight ratio becomes sufficiently large. Results show that single engine out RTLS maneuvers can be made for up to 180 seconds after lift-off and that there are scenarios for which RTLS maneuvers should be performed instead of ATP maneuvers.

The NASA Constellation program has relied heavily on Computational Fluid Dynamics simulations for generating aerodynamic databases and design loads. The Orion Project focuses on the Orion Crew Module and the Orion Launch Abort Vehicle. NASA TetrUSS codes (GridTool/VGRID/USM3D) have been applied in a supporting role to the Crew Exploration Vehicle Aerosciences Project for investigating various aerodynamic sensitivities and supplementing the aerodynamic database. This paper provides an overview of the contributions from the TetrUSS team to the Project Orion Crew Module and Launch Abort Vehicle aerodynamics, along with selected examples to highlight the challenges encountered along the way. A brief description of geometries and tasks will be discussed followed by a description of the flow solution process that produced production level computational solutions. Four tasks conducted by the USM3D team will be discussed to show how USM3D provided aerodynamic data for inclusion in the Orion aero-database, contributed data for the build-up of aerodynamic uncertainties for the aero-database, and provided insight into the flow features about the Crew Module and the Launch Abort Vehicle.

2010-01-01

An investigation into the aerodynamics of the Launch Abort Vehicle for NASA's Constellation Crew Launch Vehicle in the subsonic, incompressible flow regime was conducted in the NASA Langley 20-ft Vertical Spin Tunnel. Time histories of center of mass position and Euler Angles are captured using photogrammetry. Time histories of the wind tunnel's airspeed and dynamic pressure are recorded as well. The primary objective of the investigation is to determine models for the aerodynamic yaw and pitch moments that provide insight into the static and dynamic stability of the vehicle. System IDentification Programs for AirCraft (SIDPAC) is used to determine the aerodynamic model structure and estimate model parameters. Aerodynamic models for the aerodynamic body Y and Z force coefficients, and the pitching and yawing moment coefficients were identified.

The Range Safety Debris Catalog Analysis in Preparation for the Pad Abort One Flight Test

Kutty, Prasad M.; Pratt, William D.

2010-01-01

The Pad Abort One flight test of the Orion Abort Flight Test Program is currently under development with the goal of demonstrating the capability of the Launch Abort System. In the event of a launch failure, this system will propel the Crew Exploration Vehicle to safety. An essential component of this flight test is range safety, which ensures the security of range assets and personnel. A debris catalog analysis was done as part of a range safety data package delivered to the White Sands Missile Range in New Mexico where the test will be conducted. The analysis discusses the consequences of an overpressurization of the Abort Motor. The resulting structural failure was assumed to create a debris field of vehicle fragments that could potentially pose a hazard to the range. A statistical model was used to assemble the debris catalog of potential propellant fragments. Then, a thermodynamic, energy balance model was applied to the system in order to determine the imparted velocity to these propellant fragments. This analysis was conducted at four points along the flight trajectory to better understand the failure consequences over the entire flight. The methods used to perform this analysis are outlined in detail and the corresponding results are presented and discussed.

Tarabini, Paul V.; Gilbert, Michael G.; Beaty, James R.

2013-01-01

In 2007, the NASA Engineering and Safety Center (NESC) initiated the Max Launch Abort System Project to explore crew escape system concepts designed to be fully encapsulated within an aerodynamic fairing and smoothly integrated onto a launch vehicle. One objective of this design was to develop a more compact launch escape vehicle that eliminated the need for an escape tower, as was used in the Mercury and Apollo escape systems and what is planned for the Orion Multi-Purpose Crew Vehicle (MPCV). The benefits for the launch vehicle of eliminating a tower from the escape vehicle design include lower structural weights, reduced bending moments during atmospheric flight, and a decrease in induced aero-acoustic loads. This paper discusses the development of encapsulated, towerless launch escape vehicle concepts, especially as it pertains to the flight performance and systems analysis trade studies conducted to establish mission feasibility and assess system-level performance. Two different towerless escape vehicle designs are discussed in depth: one with allpropulsive control using liquid attitude control thrusters, and a second employing deployable aft swept grid fins to provide passive stability during coast. Simulation results are presented for a range of nominal and off-nominal escape conditions.

The mathematical models and computer program which are used to implement LASS are described. The computer program provides for a simulation of boost to orbit and abort capability from boost trajectories to a prescribed target. The abort target provides a decision point for engine shutdown from which the vehicle coasts to the vicinity of the selected abort recovery site. The simulation is a six degree of freedom simulation describing a rigid body. The vehicle is influenced by forces and moments from nondistributed aerodynamics. An adaptive autopilot is provided to control vehicle attitudes during powered and unpowered flight. A conventional autopilot is provided for study of vehicle during powered flight.

Improvement in Capsule Abort Performance Using Supersonic Aerodynamic Interaction by Fences

NASA Astrophysics Data System (ADS)

Koyama, Hiroto; Wang, Yunpeng; Ozawa, Hiroshi; Doi, Katsunori; Nakamura, Yoshiaki

The space transportation system will need advanced abort systems to secure crew against serious accidents. Here this study deals with the capsule-type space transportation systems with a Launch Abort System (LAS). This system is composed of a conic capsule as a Launch Abort Vehicle (LAV) and a cylindrical rocket as a Service Module (SM), and the capsule is moved away from the rocket by supersonic aerodynamic interactions in an emergency. We propose a method to improve the performance of the LAV by installing fences at the edges of surfaces on the rocket and capsule sides. Their effects were investigated by experimental measurements and numerical simulations. Experimental results show that the fences on the rocket and capsule surfaces increase the aerodynamic thrust force on the capsule by 70% in a certain clearance between the capsule and rocket. Computational results show the detailed flow fields where the centripetal flow near the surface on the rocket side is induced by the fence on the rocket side and the centrifugal flow near the surface on the capsule side is blocked by the fence on the capsule side. These results can confirm favorable effects of the fences on the performance of the LAS.

2011-01-01

One of NASAs challenges for the Orion vehicle is the control system design for the Launch Abort Vehicle (LAV), which is required to abort safely at any time during the atmospheric ascent portion of ight. The focus of this paper is the gain design and scheduling process for a controller that covers the wide range of vehicle configurations and flight conditions experienced during the full envelope of potential abort trajectories from the pad to exo-atmospheric flight. Several factors are taken into account in the automation process for tuning the gains including the abort effectors, the environmental changes and the autopilot modes. Gain scheduling is accomplished using a linear quadratic regulator (LQR) approach for the decoupled, simplified linear model throughout the operational envelope in time, altitude and Mach number. The derived gains are then implemented into the full linear model for controller requirement validation. Finally, the gains are tested and evaluated in a non-linear simulation using the vehicles ight software to ensure performance requirements are met. An overview of the LAV controller design and a description of the linear plant models are presented. Examples of the most significant challenges with the automation of the gain tuning process are then discussed. In conclusion, the paper will consider the lessons learned through out the process, especially in regards to automation, and examine the usefulness of the gain scheduling tool and process developed as applicable to non-Orion vehicles.

Approximately 205 million pregnancies occur each year in the worldwide. On the other hand, Spontaneous abortion has been reported in 15-20% of all diagnosed pregnancies. The most common cause of spontaneous abortion is chromosomal abnormalities of the embryo. Robertsonian translocation carriers specially 21-14 are the most common balanced rearrangement among the carrier couples with the history of spontaneous abortion. In order to search for balanced chromosomal rearrangement and cytogenetic disorders, 10 members of related family with consanguinity marriage with the history of recurrent miscarriage were assessed. Cytogenetic evaluation on the basis G-banding technique at high resolution was performed in 3 couples and their related family with the history of idiopathic RSA in order to postulate any balanced chromosomal rearrangement. six members of them appeared with robertsonian balanced translocation between chromosome No.21 to No. 14 with the karyotype of 45, XX, t (14, 21) and 45, XY, t (14, 21), which this results are in agreement with several similar works which claimed that the risk of spontaneous abortion in couples with balanced chromosomal rearrangements is higher compared with general population. Considering to results of present study, it seems as if the cytogenetic analysis of couples with the history of recurrent abortions should be suggested compulsory to estimate the probable presence of any chromosomal rearrangement. This offer wills valuable information for genetic consulting.

Use of Heated Helium to Simulate Surface Pressure Fluctuations on the Launch Abort Vehicle During Abort Motor Firing

2011-01-01

The solid-rocket plumes from the Abort motor of the Multi-Purpose Crew Vehicle (MPCV, also know as Orion) were simulated using hot, high pressure, Helium gas to determine the surface pressure fluctuations on the vehicle in the event of an abort. About 80 different abort situations over a wide Mach number range, (0.3< or =M< or =1.2) and vehicle attitudes (+/-15deg) were simulated inside the NASA Ames Unitary Plan, 11-Foot Transonic Wind Tunnel. For each abort case, typically two different Helium plume and wind tunnel conditions were used to bracket different flow matching critera. This unique, yet cost-effective test used a custom-built hot Helium delivery system, and a 6% scale model of a part of the MPCV, known as the Launch Abort Vehicle. The test confirmed the very high level of pressure fluctuations on the surface of the vehicle expected during an abort. In general, the fluctuations were found to be dominated by the very near-field hydrodynamic fluctuations present in the plume shear-layer. The plumes were found to grow in size for aborts occurring at higher flight Mach number and altitude conditions. This led to an increase in the extent of impingement on the vehicle surfaces; however, unlike some initial expectations, the general trend was a decrease in the level of pressure fluctuations with increasing impingement. In general, the highest levels of fluctuations were found when the outer edges of the plume shear layers grazed the vehicle surface. At non-zero vehicle attitudes the surface pressure distributions were found to become very asymmetric. The data from these wind-tunnel simulations were compared against data collected from the recent Pad Abort 1 flight test. In spite of various differences between the transient flight situation and the steady-state wind tunnel simulations, the hot-Helium data were found to replicate the PA1 data fairly reasonably. The data gathered from this one-of-a-kind wind-tunnel test fills a gap in the manned-space programs, and will be used to establish the acoustic environment for vibro-acoustic qualification testing of the MPCV.

Reproductive rights: an international sample.

Boyd, S

1984-01-01

This discussion considers the issue of reporductive rights in the countries of Mexico, Nigeria, Iraq, India, Germany, China, Colombia, Poland, Italy, Egypt, and Ireland. In Mexico abortion is illegal, but an estimated 3 million illegal abortions are performed yearly. Complications from these abortions send 600,000 women to Mexican hospitals each year. The Mexican government, concerned about overpopulation, appears to be moving toward a liberalization of its abortion policy. Birth control is available, often without a prescription, in pharmacies, public health agencies, and some hotels. In Nigeria if a pregnant women goes abroad she must take a medical test upon returning to prove she has remained pregnant during the trip. Underground abortionists cater especially to unmarried teenagers. Women in Nigeria obtain birth control with the written permission of their husbands. Elective abortion is illegal in Iraq. Theoretically, contraception is available to all without a doctor's prescription, but in actuality, only married women buy contraceptives which are often simply not in stock in pharmacies and stores. Elective abortion is legal in India where the government has launched an agressive family planning compaign. India's family planners have had to work against religious prohibitions against abortion. Germany has zero population growth and the lowest birthrate in the world. Birth control is available to all, both by prescription and over the counter. Abortion became legal in 1978. In China "one couple one child" is the favorite slogan and the eventual goal of an aggressive family planning campaign inaugurated in 1979. The Chinese hope this policy will reduce population growth to 5% by 1985 and allow the country to achieve zero population growth by the end of the century. To this end, the Chinese government has launched a massive public education program encouraging late marriages and the use of contraception. Abortions, sterilizations, and contraceptive devices are available free at pharmacies or the workplace. In Colombia abortion is illegal; contraceptives are available to married women by prescription. Since 1960 Polish women have had the right to abortion once they have made an "oral declaration" establishing the need for one. Birth control is freely available. Abortion is legal in Italy during the 1st trimester for women 18 or older and for women under 18 with parental permission for medical, economic, social, family, or psychological reasons. Nontherapeutic abortion is illegal in Egypt, but birth control is available to all without a prescription and is increasingly used among urban, educated Egyptians. In Ireland birth control is available only by prescription and only to married women. A constitutuional amendment bans abortion.

The Max Launch Abort System - Concept, Flight Test, and Evolution

Gilbert, Michael G.

2014-01-01

The NASA Engineering and Safety Center (NESC) is an independent engineering analysis and test organization providing support across the range of NASA programs. In 2007 NASA was developing the launch escape system for the Orion spacecraft that was evolved from the traditional tower-configuration escape systems used for the historic Mercury and Apollo spacecraft. The NESC was tasked, as a programmatic risk-reduction effort to develop and flight test an alternative to the Orion baseline escape system concept. This project became known as the Max Launch Abort System (MLAS), named in honor of Maxime Faget, the developer of the original Mercury escape system. Over the course of approximately two years the NESC performed conceptual and tradeoff analyses, designed and built full-scale flight test hardware, and conducted a flight test demonstration in July 2009. Since the flight test, the NESC has continued to further develop and refine the MLAS concept.

Ares I-X was the first flight test vehicle used in the development of NASA's Ares I crew launch vehicle. The Ares I-X used a 4-segment reusable solid rocket booster from the Space Shuttle heritage with mass simulators for the 5th segment, upper stage, crew module and launch abort system. Three modal tests were defined to verify the dynamic finite element model of the Ares I-X flight test vehicle. Test configurations included two partial stacks and the full Ares I-X flight test vehicle on the Mobile Launcher Platform. This report focuses on the first modal test that was performed on the top section of the vehicle referred to as Stack 5, which consisted of the spacecraft adapter, service module, crew module and launch abort system simulators. This report describes the test requirements, constraints, pre-test analysis, test operations and data analysis for the Ares I-X Stack 5 modal test.

The Landing Parachute Demonstrator (LPD) was conceived as a low-cost, rapidly-developed means of providing soft landing for the Max Launch Abort System (MLAS) crew module (CM). Its experimental main parachute cluster deployment technique and off-the-shelf hardware necessitated a full-scale drop test prior to the MLAS mission in order to reduce overall mission risk. This test was successfully conducted at Wallops Flight Facility on March 6, 2009, with all vehicle and parachute systems functioning as planned. The results of the drop test successfully qualified the LPD system for the MLAS flight test. This document captures the design, concept of operations and results of the drop test.

Abort Trigger False Positive and False Negative Analysis Methodology for Threshold-Based Abort Detection

NASA Technical Reports Server (NTRS)

Melcher, Kevin J.; Cruz, Jose A.; Johnson Stephen B.; Lo, Yunnhon

2015-01-01

This paper describes a quantitative methodology for bounding the false positive (FP) and false negative (FN) probabilities associated with a human-rated launch vehicle abort trigger (AT) that includes sensor data qualification (SDQ). In this context, an AT is a hardware and software mechanism designed to detect the existence of a specific abort condition. Also, SDQ is an algorithmic approach used to identify sensor data suspected of being corrupt so that suspect data does not adversely affect an AT's detection capability. The FP and FN methodologies presented here were developed to support estimation of the probabilities of loss of crew and loss of mission for the Space Launch System (SLS) which is being developed by the National Aeronautics and Space Administration (NASA). The paper provides a brief overview of system health management as being an extension of control theory; and describes how ATs and the calculation of FP and FN probabilities relate to this theory. The discussion leads to a detailed presentation of the FP and FN methodology and an example showing how the FP and FN calculations are performed. This detailed presentation includes a methodology for calculating the change in FP and FN probabilities that result from including SDQ in the AT architecture. To avoid proprietary and sensitive data issues, the example incorporates a mixture of open literature and fictitious reliability data. Results presented in the paper demonstrate the effectiveness of the approach in providing quantitative estimates that bound the probability of a FP or FN abort determination.

"Abortion will deprive you of happiness!": Soviet reproductive politics in the post-Stalin era.

PubMed

Randall, Amy E

2011-01-01

This article examines Soviet reproductive politics after the Communist regime legalized abortion in 1955. The regime's new abortion policy did not result in an end to the condemnation of abortion in official discourse. The government instead launched an extensive campaign against abortion. Why did authorities bother legalizing the procedure if they still disapproved of it so strongly? Using archival sources, public health materials, and medical as well as popular journals to investigate the antiabortion campaign, this article argues that the Soviet government sought to regulate gender and sexuality through medical intervention and health "education" rather than prohibition and force in the post-Stalin era. It also explores how the antiabortion public health campaign produced "knowledge" not only about the procedure and its effects, but also about gender and sexuality, subjecting both women and men to new pressures and regulatory norms.

To study the relationship between early spontaneous abortion and living environment, and explore the risk factors of spontaneous abortion. We conducted analysis based on the interview of 200 spontaneous abortion cases and the matched control (age +/- 2 years) by using multifactor Logistic regression analysis. The proportions of watching TV > or =10 hours/week, operating computer > or =45 hours/week, using copycat, microwave oven and mobile phone, electromagnetism equipment near the dwell or work place, e. g. switch room < or =50 m and launching tower < or =500 m in the cases are significantly higher than those in the controls in single factor analysis (all P < 0.05). After adjusted the effect of other risk factors by multifactor analysis, using microwave oven and mobile phone, contacting abnormal smell of fitment material > or =3 months, having emotional stress during the first term of pregnancy and spontaneous abortion history were significantly associated with risk of spontaneous abortion. The odds ratios of these risk factors were 2.23 and 4.63, respectively. Using microwave oven and mobile phone, contacting abnormal smell of fitment material > or =3 months, having emotional stress during the first term of pregnancy, and spontaneous abortion history are risk factors of early spontaneous abortion.

Waddlia chondrophila is a Gram-negative intracellular bacterial organism that is related to classical chlamydial species and has been implicated as a cause of abortion in cattle. Despite an increasing number of observational studies linking W. chondrophila infection to cattle abortion, little direct experimental evidence exists. Given this paucity of direct evidence the current study was carried out to investigate whether experimental challenge of pregnant cattle with W. chondrophila would result in infection and abortion. Nine pregnant Friesian-Holstein heifers received 2 × 10 8 inclusion forming units (IFU) W. chondrophila intravenously on day 105-110 of pregnancy, while four negative-control animals underwent mock challenge. Only one of the challenged animals showed pathogen-associated lesions, with the organism being detected in the diseased placenta. Importantly, the organism was re-isolated and its identity confirmed by whole genome sequencing, confirming Koch's third and fourth postulates. However, while infection of the placenta was observed, the experimental challenge in this study did not confirm the abortifacient potential of the organism.

1991-01-01

Potential radiation impacts from launch of the Ulysses solar exploration experiment were evaluated using eight postulated accident scenarios. Lifetime individual dose estimates rarely exceeded 1 mrem. Most of the potential health effects would come from inhalation exposures immediately after an accident, rather than from ingestion of contaminated food or water, or from inhalation of resuspended plutonium from contaminated ground. For local Florida accidents (that is, during the first minute after launch), an average source term accident was estimated to cause a total added cancer risk of up to 0.2 deaths. For accidents at later time after launch, a worldwide cancer risk of up to three cases was calculated (with a four in a million probability). Upper bound estimates were calculated to be about 10 times higher.

Ascent Abort-2 Module Arrives in Houston---------------------------------------------------------- NASA’s Johnson Space Center is the center of activity leading the design and build up for a critical safety test of America’s new exploration spacecraft. An Orion crew module was delivered to Houston last week for assembly and outfitting for the April 2019 Ascent Abort-2 test, to demonstrate the ability of the spacecraft’s Launch Abort System to pull the crew module to safety if an emergency ever arises during ascent to space. Doing this work at JSC is part of a lean approach to development, to minimize cost and schedule risks associated with the test. _______________________________________ FOLLOW ORION!

Crew Exploration Vehicle Ascent Abort Trajectory Analysis and Optimization

NASA Technical Reports Server (NTRS)

Falck, Robert D.; Gefert, Leon P.

2007-01-01

The Orion Crew Exploration Vehicle is the first crewed capsule design to be developed by NASA since Project Apollo. Unlike Apollo, however, the CEV is being designed for service in both Lunar and International Space Station missions. Ascent aborts pose some issues that were not present for Apollo, due to its launch azimuth, nor Space Shuttle, due to its cross range capability. The requirement that a North Atlantic splashdown following an abort be avoidable, in conjunction with the requirement for overlapping abort modes to maximize crew survivability, drives the thrust level of the service module main engine. This paper summarizes 3DOF analysis conducted by NASA to aid in the determination of the appropriate propulsion system for the service module, and the appropriate propellant loading for ISS missions such that crew survivability is maximized.

1993-03-22

S93-31601 (March 1993) --- The second Space Shuttle launch attempt of 1993 comes to an abrupt halt when one of the three main engines on the orbiter Columbia shuts down at T -3 seconds, resulting in an on-the-pad abort of Mission STS-55. This was the first time in the post-Challenger era that a main engine shutdown has halted a Shuttle launch countdown, and only the third time in the history of the program. In 1984, STS-41D was scrubbed at T -4 seconds when the orbiter General Purpose Computer detected an anomaly in a main engine, and in 1985, STS-51F was halted at T -3 seconds due to a main engine malfunction that caused shutdown of all three engines. Columbia had been scheduled to lift off from Launch Pad 39B is the Space Shuttle Discovery, undergoing preparations for lift off on Mission STS-56.

The aim of this study was the characterization of the implantation site through histological and immunohistochemical exams and the evaluation of the changes that appear in the pregnancies ended by spontaneous abortion compared to normal pregnancies ended by requested abortion. One hundred eight patients were divided in two groups: the study group that included 58 patients with spontaneous abortion and the control group that included 50 patients with requested abortion. There has been made uterine curettage in all the cases after a complete preoperative evaluation and the obtained product was sent for histopathological evaluation and immunohistochemical study using a VEGF antibody. Studying the histological sections, we noticed the vasculogenesis stages chronology and then according to the histological aspects of normal pregnancy we noticed the histological changes that occurred at the site of implantation in the cases with pathological pregnancies ended by miscarriage. Our results from this study seem to indicate a correlation between decidual vascular changes and the appearance of miscarriage. In pregnancies ended by miscarriage, we found delays in the trophoblast development according to the gestational age at which the event abortifacient happened. The study emphases the temporal differentiation of utero-placental angiogenesis comparing to villous vasculogenesis and angiogenesis in the first trimester miscarriage and normal pregnancy. At the control group, VEGF expression was positive in 88% of cases, while in the study group, pregnancies ended by spontaneous abortion, positive expression of VEGF was present in only 31% of cases. Our data suggest vascular disorders and are in concordance with other histological and ultrasound studies postulating the idea of a link between miscarriage and placental vascular bed pattern changes.

Comment: unethical ethics investment boycotts and abortion.

PubMed

Furedi, A

1998-01-01

Ethical investment funds have traditionally boycotted the arms industry, companies known to pollute the environment, and those involved in animal research. However, recent newspaper reports suggest that some investment funds plan to also boycott hospitals and pharmaceutical companies involved in abortion-related activities. Ethical Financial, anti-abortion independent financial advisors, are encouraging a boycott of investment in private hospitals and manufacturers of equipment involved in abortions, and pharmaceutical firms which produce postcoital contraception or conduct embryo research. Ethical Financial claims that Family Assurance has agreed to invest along anti-abortion lines, Aberdeen Investment is already boycotting companies linked to abortion, and Hendersons ethical fund plans to follow suit. There is speculation that Standard Life, the largest mutual insurer in Europe, will also refuse to invest in abortion-related concerns when it launches its ethical fund in the spring. Managers of ethical funds should, however, understand that, contrary to the claims of the anti-choice lobby, there is extensive public support for legal abortion, emergency contraception, and embryo research. Individuals and institutions which contribute to the development of reproductive health care services are working to alleviate the distress of unwanted pregnancy and infertility, laudable humanitarian goals which should be encouraged. Those who try to restrict the development of abortion methods and services simply show contempt for women, treating them as people devoid of conscience who are incapable of making moral choices.

Lo, Sue S T; Ho, P C

2015-10-01

Research on medical abortion has been conducted in Hong Kong since the 1990s. It was not until 2011 that the first-trimester medical abortion service was launched. Mifepristone was registered in Hong Kong in April 2014 and all institutions that are listed in the Gazette as a provider for legal abortion can purchase mifepristone from the local provider. This article aimed to share our 3-year experience of this service with the local medical community. Our current protocol is safe and effective, and advocates 200-mg mifepristone and 400-µg sublingual misoprostol 24 to 48 hours later, followed by a second dose of 400-µg sublingual misoprostol 4 hours later if the patient does not respond. The complete abortion rate is 97.0% and ongoing pregnancy rate is 0.4%. Some minor side-effects have been reported and include diarrhoea, fever, abdominal pain, and allergy. There have been no serious adverse events such as heavy bleeding requiring transfusion, anaphylactic reaction, septicaemia, or death.

STS-55 pad abort: Engine 2011 oxidizer preburner augmented spark igniter check valve leak

NASA Technical Reports Server (NTRS)

1993-01-01

The STS-55 initial launch attempt of Columbia (OV102) was terminated on KSC launch pad A March 22, 1993 at 9:51 AM E.S.T. due to violation of an ME-3 (Engine 2011) Launch Commit Criteria (LCC) limit exceedance. The event description and timeline are summarized. Propellant loading was initiated on 22 March, 1993 at 1:15 AM EST. All SSME chill parameters and launch commit criteria (LCC) were nominal. At engine start plus 1.44 seconds, a Failure Identification (FID) was posted against Engine 2011 for exceeding the 50 psia Oxidizer Preburner (OPB) purge pressure redline. The engine was shut down at 1.50 seconds followed by Engines 2034 and 2030. All shut down sequences were nominal and the mission was safely aborted. The OPB purge pressure redline violation and the abort profile/overlay for all three engines are depicted. SSME Avionics hardware and software performed nominally during the incident. A review of vehicle data table (VDT) data and controller software logic revealed no failure indications other than the single FID 013-414, OPB purge pressure redline exceeded. Software logic was executed according to requirements and there was no anomalous controller software operation. Immediately following the abort, a Rocketdyne/NASA failure investigation team was assembled. The team successfully isolated the failure cause to the oxidizer preburner augmented spark igniter purge check valve not being fully closed due to contamination. The source of the contaminant was traced to a cut segment from a rubber O-ring which was used in a fine clean tool during valve production prior to 1992. The valve was apparently contaminated during its fabrication in 1985. The valve had performed acceptably on four previous flights of the engine, and SSME flight history shows 780 combined check valve flights without failure. The failure of an Engine 3 (SSME No. 2011) check valve to close was sensed by onboard engine instruments even though all other engine operations were normal. This resulted in an engine shutdown and safe sequential shutdown of all three engines prior to ignition of the solid boosters.

The ocular pathology of Norrie disease in a fetus of 11 weeks' gestational age.

PubMed

Parsons, M A; Curtis, D; Blank, C E; Hughes, H N; McCartney, A C

1992-01-01

The ocular pathology of Norrie disease was studied for the first time in a fetus of 11 weeks' gestation, following prenatal diagnosis using genetic markers for Norrie disease and elective abortion. The eyes were histologically normal, with no evidence of primary neuroectodermal maldevelopment of the retina, previously postulated to be the cause of the ocular changes. We believe that the retinal and other manifestations of Norrie disease are the result of a primary abnormality of vascular proliferation, probably in relation to persistent hyperplastic primary vitreous after approximately 14 weeks' gestation. We postulate that the ocular and otological effects of Norrie disease may be due to a genetically mediated abnormality of secretion of, or sensitivity to, angiogenic growth factors at endodermal-neuroectodermal interfaces during fetal and postnatal development.

Shuttle Orbiter Contingency Abort Aerodynamics: Real-Gas Effects and High Angles of Attack

NASA Technical Reports Server (NTRS)

Prabhu, Dinesh K.; Papadopoulos, Periklis E.; Davies, Carol B.; Wright, Michael J.; McDaniel, Ryan D.; Venkatapathy, Ethiraj; Wercinski, Paul F.

2005-01-01

An important element of the Space Shuttle Orbiter safety improvement plan is the improved understanding of its aerodynamic performance so as to minimize the "black zones" in the contingency abort trajectories [1]. These zones are regions in the launch trajectory where it is predicted that, due to vehicle limitations, the Orbiter will be unable to return to the launch site in a two or three engine-out scenario. Reduction of these zones requires accurate knowledge of the aerodynamic forces and moments to better assess the structural capability of the vehicle. An interesting aspect of the contingency abort trajectories is that the Orbiter would need to achieve angles of attack as high as 60deg. Such steep attitudes are much higher than those for a nominal flight trajectory. The Orbiter is currently flight certified only up to an angle of attack of 44deg at high Mach numbers and has never flown at angles of attack larger than this limit. Contingency abort trajectories are generated using the data in the Space Shuttle Operational Aerodynamic Data Book (OADB) [2]. The OADB, a detailed document of the aerodynamic environment of the current Orbiter, is primarily based on wind-tunnel measurements (over a wide Mach number and angle-of-attack range) extrapolated to flight conditions using available theories and correlations, and updated with flight data where available. For nominal flight conditions, i.e., angles of attack of less than 45deg, the fidelity of the OADB is excellent due to the availability of flight data. However, at the off-nominal conditions, such as would be encountered on contingency abort trajectories, the fidelity of the OADB is less certain. The primary aims of a recent collaborative effort (completed in the year 2001) between NASA and Boeing were to determine: 1) accurate distributions of pressure and shear loads on the Orbiter at select points in the contingency abort trajectory space; and 2) integrated aerodynamic forces and moments for the entire vehicle and the control surfaces (body flap, speed brake, and elevons). The latter served the useful purpose of verification of the aerodynamic characteristics that went into the generation of the abort trajectories.

Induced abortion patterns and determinants among married women in China: 1979 to 2010.

PubMed

Wang, Cuntong

2014-05-01

China has launched the one-child policy to control its rapidly expanding population since 1979. Local governments, tasked with limiting regional birth rates, commonly imposed induced abortions. After 1994, China's family planning policy was relatively loosened and mandatory induced abortion gradually gave way to client-centered and informed-choice contraceptive policy and the "Compensation" Fee policy. This study assesses trends in and determinants of induced abortion among married women aged 20-49 in China from 1979 to 2010, using data from national statistics and nationally representative sample surveys. The incidence of induced abortions among married women aged 20-49 began to decrease in the mid-1990s. The induced abortion rate reached its highest level in the early 1980s (56.07%) and its lowest level in the 2000s (18.04%), with an average annual rate of 28.95% among married women 20-49 years old. The likelihood of a pregnant woman undergoing an induced abortion during this period depended not only on individual characteristics (including ethnicity, age, education level, household registration, number of children, and sex of children), but also on the stringency of the family planning policy in place. The less stringent the family planning policy, the less likely married women were to undergo an induced abortion. Copyright © 2014 Reproductive Health Matters. Published by Elsevier Ltd.

Orion Launch Abort Vehicle Attitude Control Motor Testing

NASA Technical Reports Server (NTRS)

Murphy, Kelly J.; Brauckmann, Gregory J.; Paschal, Keith B.; Chan, David T.; Walker, Eric L.; Foley, Robert; Mayfield, David; Cross, Jared

2011-01-01

Current Orion Launch Abort Vehicle (LAV) configurations use an eight-jet, solid-fueled Attitude Control Motor (ACM) to provide required vehicle control for all proposed abort trajectories. Due to the forward position of the ACM on the LAV, it is necessary to assess the effects of jet-interactions (JI) between the various ACM nozzle plumes and the external flow along the outside surfaces of the vehicle. These JI-induced changes in flight control characteristics must be accounted for in developing ACM operations and LAV flight characteristics. A test program to generate jet interaction aerodynamic increment data for multiple LAV configurations was conducted in the NASA Ames and NASA Langley Unitary Plan Wind Tunnels from August 2007 through December 2009. Using cold air as the simulant gas, powered subscale models were used to generate interaction data at subsonic, transonic, and supersonic test conditions. This paper presents an overview of the complete ACM JI experimental test program for Orion LAV configurations, highlighting ACM system modeling, nozzle scaling assumptions, experimental test techniques, and data reduction methodologies. Lessons learned are discussed, and sample jet interaction data are shown. These data, in conjunction with computational predictions, were used to create the ACM JI increments for all relevant flight databases.

Aeroacoustics of Space Vehicles

NASA Technical Reports Server (NTRS)

Panda, Jayanta

2014-01-01

While for airplanes the subject of aeroacoustics is associated with community noise, for space vehicles it is associated with vibro-acoustics and structural dynamics. Surface pressure fluctuations encountered during launch and travel through lower part of the atmosphere create intense vibro-acoustics environment for the payload, electronics, navigational equipment, and a large number of subsystems. All of these components have to be designed and tested for flight-certification. This presentation will cover all three major sources encountered in manned and unmanned space vehicles: launch acoustics, ascent acoustics and abort acoustics. Launch pads employ elaborate acoustic suppression systems to mitigate the ignition pressure waves and rocket plume generated noise during the early part of the liftoff. Recently we have used large microphone arrays to identify the noise sources during liftoff and found that the standard model by Eldred and Jones (NASA SP-8072) to be grossly inadequate. As the vehicle speeds up and reaches transonic speed in relatively denser part of the atmosphere, various shock waves and flow separation events create unsteady pressure fluctuations that can lead to high vibration environment, and occasional coupling with the structural modes, which may lead to buffet. Examples of wind tunnel tests and computational simulations to optimize the outer mold line to quantify and reduce the surface pressure fluctuations will be presented. Finally, a manned space vehicle needs to be designed for crew safety during malfunctioning of the primary rocket vehicle. This brings the subject of acoustic environment during abort. For NASAs Multi-Purpose Crew Vehicle (MPCV), abort will be performed by lighting rocket motors atop the crew module. The severe aeroacoustics environments during various abort scenarios were measured for the first time by using hot helium to simulate rocket plumes in the Ames unitary plan wind tunnels. Various considerations used for the helium simulation and the final confirmation from a flight test will be presented.

Timing control system

Wiker, Gordon A. (Inventor); Wells, Jr., George H. (Inventor)

1989-01-01

A timing control system is disclosed which is particularly useful in connection with simulated mortar shells. Special circuitry is provided to assure that the shell does not overshoot, but rather detonates early in case of an improper condition; this ensures that ground personnel will not be harmed by a delayed detonation. The system responds to an externally applied frequency control code which is configured to avoid any confusion between different control modes. A premature detonation routine is entered in case an improper time-setting signal is entered, or if the shell is launched before completion of the time-setting sequence. Special provisions are also made for very early launch situations and improper detonator connections. An alternate abort mode is provided to discharge the internal power supply without a detonation in a manner that can be externally monitored, thereby providing a mechanism for non-destructive testing. The abort mode also accelerates the timing function for rapid testing.

Shuttle Abort Flight Management (SAFM) - Application Overview

NASA Technical Reports Server (NTRS)

Hu, Howard; Straube, Tim; Madsen, Jennifer; Ricard, Mike

2002-01-01

One of the most demanding tasks that must be performed by the Space Shuttle flight crew is the process of determining whether, when and where to abort the vehicle should engine or system failures occur during ascent or entry. Current Shuttle abort procedures involve paging through complicated paper checklists to decide on the type of abort and where to abort. Additional checklists then lead the crew through a series of actions to execute the desired abort. This process is even more difficult and time consuming in the absence of ground communications since the ground flight controllers have the analysis tools and information that is currently not available in the Shuttle cockpit. Crew workload specifically abort procedures will be greatly simplified with the implementation of the Space Shuttle Cockpit Avionics Upgrade (CAU) project. The intent of CAU is to maximize crew situational awareness and reduce flight workload thru enhanced controls and displays, and onboard abort assessment and determination capability. SAFM was developed to help satisfy the CAU objectives by providing the crew with dynamic information about the capability of the vehicle to perform a variety of abort options during ascent and entry. This paper- presents an overview of the SAFM application. As shown in Figure 1, SAFM processes the vehicle navigation state and other guidance information to provide the CAU displays with evaluations of abort options, as well as landing site recommendations. This is accomplished by three main SAFM components: the Sequencer Executive, the Powered Flight Function, and the Glided Flight Function, The Sequencer Executive dispatches the Powered and Glided Flight Functions to evaluate the vehicle's capability to execute the current mission (or current abort), as well as more than IS hypothetical abort options or scenarios. Scenarios are sequenced and evaluated throughout powered and glided flight. Abort scenarios evaluated include Abort to Orbit (ATO), Transatlantic Abort Landing (TAL), East Coast Abort Landing (ECAL) and Return to Launch Site (RTLS). Sequential and simultaneous engine failures are assessed and landing footprint information is provided during actual entry scenarios as well as hypothetical "loss of thrust now" scenarios during ascent.

Fathers and fetuses.

PubMed

Harris, George W

1986-04-01

Harris postulates that in certain instances it would be morally impermissible for a woman to have an abortion because it would be a wrongful harm to the father and a violation of his autonomy. He constructs and analyzes five cases chosen to elucidate the moral issues involved and concludes that, for a man to lay claim to the fetus being his in a sense that the mother is obligated to respect, the fetus must be the result of his having pursued a legitimate interest in procreation in a morally legitimate way. When a man has satisfied the requirements of autonomy both for himself and for his sexual partner in regard to the interest in procreation, the woman has a prima facie obligation to him not to harm the fetus. Therefore, unless there is some contravening moral consideration that overrides this obligation, the abortion of the fetus is morally impermissible.

The astronauts toured the pad for an up-close look at modifications that are in work for the SpaceX Crew Dragon flight tests. The tower modifications included removal of the space shuttle era rotating service structure. Future integration of the crew access arm will allow for safe crew entry for launch and exit from the spacecraft in the unlikely event a pad abort is required.

Orion / Space Launch System: NASA has selected the design of a new Space Launch System SLS that will take the agency's astronauts farther into space than ever before and provide the cornerstone for America's future human space exploration efforts. The SLS will launch human crews beyond low Earth orbit in the Orion Multi-Purpose Crew Vehicle. Orion is America’s next generation spacecraft. It will serve as the exploration vehicle that will provide emergency abort capability, sustain the crew during space travel, carry the crew to distant planetary bodies, and provide safe return from deep space.

Production Transcript for Ep25_ A Rocket on a Rocket.mp3 [00:00:00] >> Houston We Have a Podcast. Welcome to the official podcast of the NASA Johnson Space Center. I'm Gary Jordan, and I'll be your host today. So before we cross into the new year and witness the spectacle of thousands of fireworks launching everywhere, for Episode 25, we're talking about rockets -- specifically, a special rocket that's, well, on a rocket. So today, we're talking about launch abort systems with Wahab Alshahin. He's a guidance, navigation, and control engineer here at the NASA Johnson Space Center in Houston, Texas, and we had a great discussion about what a launch abort system is, how it works, a little bit of history, and why they're necessary to send humans into space. So with no further delay, let's go light speed and jump right ahead to our talk with Mr. Wahab Alshahin. Enjoy. [00:00:43] [ Music ] But Wahab, it's actually, it's really good to see you, and thanks for coming on the podcast today, for taking the time to do this. [00:01:11] >> Yeah, of course. [00:01:12] >> This is an interesting topic because it's sort of, you know, we were talking a lot about a lot of big things, right. We were talking the International Space Station. We talked about space food, landing, these big concepts, but this is sort of, it is a big concept, but it's kind of like, you know, if you're looking at a rocket, you're looking at the tippy, tippy top of a rocket. [00:01:30] >> Yeah. [00:01:31] >> So, yeah. I mean, that's kind of what we're, what this is, right? This is about, I titled this "A Rocket on a Rocket." Is that a fair way to say it? [00:01:38] >> That, so when you-- [00:01:39] >> Okay. [00:01:39] >> Told me that you mention, or you were trying to call it a rocket on a rocket, I thought about that, and then I thought about the specifications for what this thing actually does. [00:01:46] >> Yeah. [00:01:47] >> It's 30 feet tall. It produces 400,000 pounds plus or thrust. [00:01:51] >> Whoa. [00:01:52] >> That is basically, you, at that point, yes, that is a rocket that is sitting on top of an even larger rocket. [laughs] Yeah, so certainly, that's a fair assessment. Yeah. [00:02:00] >> Wow, all right. [00:02:01] >> Yeah. [00:02:02] >> Yeah, I didn't think, because I was like, it kind of is, right, because the whole point of this is it's called a launch abort system, correct? So-- [00:02:10] >> That's right. [00:02:10] >> If a rocket is launching and something goes wrong, there is another rocket on top of it that could safely get our crew members away. [00:02:17] >> That's correct. [00:02:18] >> Is that kind of the overall concept of why this is what it is? [00:02:22] >> Yeah, yeah. [00:02:22] >> Okay. [00:02:23] >> So with regards to the capability, yeah, it is, the primary purpose is to separate the crew module from the launch vehicle that may or may not be having a problem. So whether or not you use a tower or you have built-in engines like some of our private partners, like SpaceX and Boeing have built-in engines as opposed to tower-- [00:02:41] >> Oh, okay. [00:02:42] >> That's up to the design engineers, but form, first and foremost, it's separating the crew from the failing launch vehicle. That's the primary purpose. [00:02:49] >> Awesome. So that's, yeah, that's kind of the overarching, you know, what is the purpose of this? [00:02:54] >> That's right. [00:02:55] >> That's pretty much it, okay. So like you said -- what was that number you said at the very beginning? How many pounds of thrust? [00:03:01] >> So for the Orion launch abort system-- [00:03:03] >> Okay. [00:03:04] >> The abort motor that separates that crew module from the launch vehicle generates about 400,000 pounds of thrust. [00:03:10] >> Whoa. [00:03:11] >> Yeah. [00:03:11] >> Okay. [00:03:12] >> Yeah, so [laughter] it is-- [00:03:12] >> That's a lot. [00:03:14] >> Yes, yeah. [00:03:15] >> Wow. What, compared to, I mean, when you think about it, you're talking about, it's called aborting a launch, right? So really, you're escaping-- [00:03:22] >> That's right. [00:03:23] >> From a speeding rocket. [00:03:24] >> That's right. [00:03:24] >> Right? So what kinds of, what, that's the energy that really has to go into that, so how does that happen? [00:03:30] >> Yeah. So again, so I work on the Orion launch abort system. [00:03:34] >> Okay. [00:03:34] >> So speaking from what we're doing on that project, but-- [00:03:38] >> Okay. [00:03:38] >> Like I said, there are different kinds of launch abort systems and people do things differently. But in general, you have to be able to provide capability to separate from the rocket all the way from when it's on the pad, essentially prior to launching, up to prior to going into orbit. So that design space is zero feet in altitude to 300,000 feet in altitude and traveling at zero miles per hour to seven times the speed of sound. [00:04:03] >> Whoa. [00:04:04] >> So you're, a single system has to be capable and robust enough to provide abort capability throughout that entire spectrum. [00:04:12] >> Okay. [00:04:12] >> So you can imagine, yeah, you have to have enough thrust capability to separate when you're not moving, but also when the vehicle is traveling at thousands of miles per hour. [00:04:20] >> Whoa, okay. [00:04:21] >> Yeah. [00:04:21] >> But there's, like, okay, so you said -- you kind of hinted at this -- there's different types, right, and so for you specifically, you're working on Orion. [00:04:28] >> That's right. [00:04:28] >> And I can't believe it, but up until this point, we actually haven't had a podcast that's just the overall concept of Orion. We're actually starting with the launch abort. So let's-- [00:04:36] >> Okay. [laughs] [00:04:36] >> Go back, and let's talk about, you know, what is Orion? [00:04:39] >> Sure. [00:04:39] >> What are you designing this launch abort system for? [00:04:42] >> All right. So in general, Orion is the crew module that is built, that's going to be built to house our astronauts and take them to low Earth orbit as well as our deep-space missions, so whether that be to the Moon or Mars. [00:04:52] >> Okay. [00:04:53] >> So that's just the capsule itself. [00:04:55] >> I see. [00:04:55] >> The part that I work on is the tower that is attached at the top of the crew module, which is on top of the large space launch system, which is our rocket. So-- [00:05:06] >> Okay. [00:05:06] >> Yeah. In total, the rocket plus the crew module plus the abort system is about 330 feet high. [00:05:12] >> Okay. [00:05:13] >> Yeah, so it's a [laughs] big rocket, yeah. [00:05:15] >> Yeah. That's like a tall building. [00:05:16] >> That is basically a tall building. That's right. [00:05:18] >> Yeah, that's amazing. Okay, cool. So you're, if I'm imagining, so the Orion capsule, right. I, if I were to imagine a shape, I'd kind of imagine it mostly like a capsule or like sort of the rounded trapezoid. Is that a fair-- [00:05:30] >> A rounded trapezoid is definitely fair. [00:05:32] >> Is that kind of the -- yes. [00:05:33] >> Yep, that's right. [00:05:34] >> So if-- [00:05:34] >> Yeah. [00:05:34] >> You're imagining a rounded trapezoid with the angles inward going, or the angles on the side going up, you kind of just fit this you said tower right on top of it? [00:05:42] >> That's right, yeah. And, or the Orion design actually calls for a shroud that actually encompasses and goes around the Orion or Orion crew module itself. So we have a shroud that covers the capsule. [00:05:53] >> Okay, so it's not just-- [00:05:54] >> Yeah. [00:05:54] >> A tower-- [00:05:54] >> Yeah. [00:05:55] >> A pole sticking up. You have, you're actually-- [00:05:56] >> That's right. [00:05:56] >> Covering the-- [00:05:57] >> Yeah. Previously-- [00:05:58] >> Okay. [00:05:59] >> Previously, for Apollo and Mercury, it was just the tower. [00:06:01] >> I see. [00:06:01] >> But we opted for a shroud instead for better aerodynamics. [00:06:04] >> I was just about to ask why, but-- [00:06:06] >> One reason. [00:06:06] >> Okay, okay. Very cool. [00:06:07] >> Among others. [00:06:07] >> All right, well-- [00:06:08] >> Yeah. [00:06:08] >> So, okay, so the idea is that, like you said, the purpose is to safely get the crew away from a speeding rocket or in several different scenarios, right. [00:06:17] >> Yeah. [00:06:17] >> So what needs to happen, right, just in general talking about the general concept of launch abort system? It's not just fire a rocket and just go wherever you need to go, right? There's some intricate engineering that goes into that. [00:06:30] >> That's right. I call it an abort ballet, yeah. [laughs] It is, it's definitely, this is one of, probably one of the hardest things to work on in engineering. [00:06:40] >> Wow. [00:06:40] >> Like I said, just because you have to design something that's so robust, that's built to work in any contingency failure, so it's kind of like a Murphy's law. You have to assume what can go wrong will go wrong. [00:06:51] >> Yeah. You have to be the devil's advocate. [00:06:53] >> But-- [00:06:53] >> Every situation. [00:06:54] >> Exactly. [00:06:54] >> Yeah. [00:06:54] >> Exactly, so for Orion specifically, there's three motors, so let's just think, visualize this in your head. You're-- [00:07:01] >> Okay. [00:07:01] >> Going up on the rocket and you're at some altitude, you know, barreling toward space. Your mission's fine. [00:07:07] >> Okay. [00:07:07] >> Something happens, and there's a, either a software switch or some kind of signal that indicates that there's something wrong with the launch vehicle. That gets sent to the flight computer. The flight computer says, all right, we need to escape. As soon as that command is sent, the abort motor burns, is ignited, and it starts burning, and that burns for about five seconds, and that does the heavy lifting of separating the crew module from the launch vehicle. [00:07:30] >> Is that, is it fair to say that's the most powerful-- [00:07:32] >> That's right. It definitely is. [00:07:33] >> Okay. [00:07:33] >> Yeah, yeah. The abort motor is, it's completely passive. It's not controlled in any way. It just fire and go. It just separates the crew module from the launch vehicle. [00:07:41] >> So there's no big, red Abort button in the scenario, right? [00:07:43] >> There is not, no. [00:07:44] >> It's automatic. [00:07:44] >> This is all automatic. [00:07:45] >> Okay, okay. [00:07:46] >> That's right. So once we've separated, there's another motor that's on top of the -- it kind of acts like a very large lever arm at the top of the 30-foot abort tower, and that's the attitude control motor. It's the most complex motor of the three that are inside in the launch abort system. And the purpose of that one is to literally flip, you're basically doing a front flip in midair of the crew module because if you imagine we just separated, we're facing with the tower pointed forward. In order to deploy the parachutes, we have to go heat shield forward. So we have to do an entire 180-degree reorientation maneuver so that the capsule is falling blunt end first. [00:08:26] >> Whoa, okay. [00:08:27] >> Yeah. [00:08:27] >> So you fire the super-powerful rockets to get away from the larger rockets that you're-- [00:08:31] >> That's right. [00:08:32] >> On top of, and then you fire more rockets so that you do a front flip-- [00:08:35] >> That's right. [00:08:35] >> And get oriented. Okay. [00:08:36] >> Yeah. [00:08:37] >> So it's very complex. [00:08:38] >> Yep, and then once you're, once you are in the orientation that you want for deploying the parachutes, there's a third motor, that jettison motor, that actually separate, now there's another separation of the-- [00:08:47] >> Yeah. [00:08:47] >> Launch abort system, which you no longer need-- [00:08:49] >> Because it already did the front flip. [00:08:50] >> From the -- that's right-- [00:08:51] >> Yeah. [00:08:51] >> From the crew module. [00:08:52] >> Okay, cool. [00:08:52] >> Yeah. So there's three separate motors on the launch abort system that have nothing to do with getting you to space. [laughs] Yeah. [00:08:58] >> It's just to get you away from-- [00:09:00] >> That's right. [00:09:01] >> This rocket that-- [00:09:02] >> That's right. [00:09:03] >> Doesn't, I guess is not going to take you to space anymore. [00:09:06] >> Yeah. [00:09:07] >> So the launch abort system is just a series of motors, a series of rockets, right? The parachutes are completely separate? [00:09:12] >> That's right. [00:09:13] >> Once it does that separation, then the parachutes are coming from the capsule, so-- [00:09:17] >> Yeah. Yeah, exactly. [00:09:18] >> Okay. [00:09:18] >> And depending on how high we are in altitude, the parachute sequence is no different than what it would be if we were coming back from a mission. Say we had a successful mission and we were deploying the parachutes. It goes through that same process. [00:09:29] >> Nice. [00:09:29] >> Yep. [00:09:29] >> Okay, so there has to be a lot of, there has to be a story behind how you got to this, did you say rocket ballet? Is that what you called it? [00:09:36] >> Yeah. [00:09:36] >> It's, yeah, is-- [00:09:37] >> Or abort ballet. [00:09:38] >> Abort ballet, yeah. There has to be a story to it. So what, how was, how did launch abort systems come about? What was the initial, you know, design of this system? [00:09:46] >> Yeah. So obviously, it was first conceived when we were thinking about human spaceflight, so back in the 1950's and '60's during the Apollo mission. [00:09:53] >> Okay. [00:09:53] >> So that was first and foremost. We knew that this was a dangerous field, especially back then doing it for the first time. We didn't necessarily expect failures, but we knew that those were a high, they were high in likelihood. [00:10:05] >> Yeah. [00:10:05] >> So we had to design something to save the crew in the event of one of those emergencies. So that's kind of where it all started. And ever since then, we've, every human-rated abort vehicle, or, I'm sorry, every human-rated vehicle that goes to space has to have a escape mechanism, and that's, that just varies across different people who are designing it. [00:10:26] >> Nice. Okay, so how did they, you know, what were some of the early designs, and kind of how did you go from those early designs to more modern? Like, what did you learn along the way? [00:10:38] >> Yeah. So all of the early designs, and by early designs, I'm talking about the early Soyuz, Mercury, Apollo, all those were a tower design. [00:10:46] >> Okay. [00:10:46] >> So however that was conceived, people decided that was the way to do it. It made the most engineering sense. Just something to pull the capsule away from the launch vehicle that-- [00:10:57] >> Right. [00:10:58] >> That's failing. So all those kind of operated the same way. And for all those systems, they're all passively controlled. So they're not actively controlled. So the motors are not controlled in any way. They just burn, and separate the crew, and then dispose of the crew capsule so that it can separate, deploy the parachutes. [00:11:16] >> Okay. [00:11:17] >> Yeah. So all those are passively controlled. We've kind of moved into the world of active control, so that's where we are now. The, like I said, the Orion launch abort motor, launch abort system, sorry, is completely, the attitude control motor portion of it that actually steers the abort motor-- [00:11:34] >> The front flip. [00:11:34] >> Yep, the front flip, [laughs] is controlled. Yeah. You would not be able to do that with a passive system. [00:11:38] >> Okay. [00:11:38] >> So that's actively controlled. [00:11:40] >> So for different rockets, there have to be different designs, right? So the tower design seems to be pretty, a pretty good one for-- [00:11:47] >> Yeah. [00:11:48] >> A upward-facing rocket. I know something had to change for the shuttle arrow, right? [00:11:52] >> That's right. [00:11:53] >> Okay. [00:11:53] >> Yeah, so the shuttle arrow was a little interesting because it was basically a, you know, a space plane, essentially, that was attached to the side of an external tank and two solid rocket boosters. And unfortunately, I don't think we had, we definitely don't have as great of abort capability on the abort, or, I'm sorry, on the space shuttle as we do on Orion. Kind of one of the main reasons we've shifted back towards toward the long, monolithic rocket with the capsule on top. [00:12:22] >> Sure. [00:12:22] >> It's just a safer design in general. [00:12:24] >> Yeah. [00:12:24] >> And most people don't know this, but for the space shuttle, you could not do an abort from the space shuttle stack until the solid rocket boosters were completely burned out-- [00:12:34] >> Oh. [00:12:34] >> Which-- [00:12:35] >> So even, you had to keep ascending-- [00:12:36] >> That's right. [00:12:37] >> Wow. [00:12:37] >> There was no abort capability until the solid rocket motor, solid rocket boosters burned out, which was about two-and-a-half minutes. [00:12:43] >> Oh, wow. [00:12:44] >> So two-and-a-half minutes, that puts you at about, I don't know, 140,000 feet. [00:12:49] >> Wow. [00:12:49] >> That's basically halfway up to the current abort capability. I mean-- [00:12:55] >> Yeah. [00:12:56] >> I mentioned earlier the Orion launch abort system is capable up to 300,000 feet, so half of that is about 150. [00:13:02] >> Right. [00:13:02] >> So for half of that entire region, you couldn't abort. But now, with this system, post space shuttle, we can. We have that-- [00:13:09] >> There you go. [00:13:09] >> Abort capability. [00:13:10] >> And your window's that much smaller, right-- [00:13:11] >> Right. [00:13:12] >> Because you're constantly accelerating up there. So even the window from 150,000 feet to 300,000 feet is-- [00:13:17] >> Right. [00:13:17] >> That's a quicker window. [00:13:17] >> Exactly, exactly. Yeah, so again, that was, that's kind of a side topic, but one of the reasons we-- [00:13:23] >> Yeah, right. [00:13:23] >> Went back to the stack monolithic approach. [00:13:26] >> Got it, sure. [00:13:26] >> But for our design, the, like I mentioned this earlier, if we don't have an abort, that entire abort tower and those, all those motors are just jettison. We don't use them at all. So they serve no purpose outside of an abort. [00:13:38] >> I see. [00:13:39] >> Yeah. [00:13:39] >> When are they jettisons? If, for an Orion mission, right. Say the Orion, the SLS is on top of-- [00:13:44] >> Yeah. [00:13:44] >> Is the rocket, right. Space launch system. That's the one that we're designing and you put the-- [00:13:47] >> That's right. [00:13:48] >> Orion right on top. Everything goes according to plan. You're in space. You're doing your thing. At what point is the launch abort system going to say, I'm not needed anymore; I'm going to detach? [00:13:57] >> Yeah, like, it's a little after 300,000 feet. And at that-- [00:14:01] >> Oh, okay. [00:14:01] >> Point, you could still have an abort. We just wouldn't use the launch abort tower. We would use the service module. [00:14:06] >> Oh, okay. [00:14:07] >> Yeah, so that would-- [00:14:08] >> So that's the part that, if you're looking at the rocket, is underneath it. [00:14:11] >> That's right. Yep. [00:14:12] >> I see, okay. [00:14:13] >> And so we would use that engine for an abort to orbit or something like that. [00:14:16] >> Okay. [00:14:17] >> Yeah. [00:14:17] >> Okay. [00:14:17] >> So at that point, you are, your requirements aren't necessarily, come back to the Earth. It's, you are high enough that you can abort to orbit, some low Earth orbit and, or not low Earth, but some lower orbit, and then come back. [00:14:28] >> Yeah, it's not like, oh, I need to get back right now-- [00:14:30] >> That's right. [00:14:30] >> With launching. Okay, okay. So you got some time, and you have to, your, it's different physics, right? Now you're in orbit. Now you're-- [00:14:36] >> Yeah, yeah. There's, yeah, there's no air drag, or very little, rather. [00:14:39] >> Yeah, so you're talking about a whole nother thing. We'll have to do another podcast now. [00:14:42] >> That's right. [laughter] [00:14:45] >> Okay, very cool. So, you know, going back to Orion, we talked a little bit about, you know, the history of launch abort. It seems like it was this tower, and let's just keep improving it. So, you know, what is -- we'll get into the weeds in a little bit -- what are some of the cool things? You mentioned a shroud. [00:15:01] >> Yeah. [00:15:01] >> Shroud is one of the things that's different about Orion, but what's some of the other parts that are different? [00:15:06] >> From the heritage technology that we were, the heritage designs that we had in the past, we being NASA-- [00:15:12] >> Okay. [00:15:12] >> The biggest thing is actively controlling this. Yeah. [00:15:14] >> The front flip. I keep going back to that. [00:15:16] >> So it is, that's, yeah. It's a, you can call it front flip, fine. It, the entire system has its own flight computer and flight brain, so that's just, it's one extra level of complexity. And like I said, being an engineer on the project, it's really interesting to kind of work on it day in, day out, but there, you have to design, you have to overdesign everything because you don't know-- [00:15:41] >> Yeah. [00:15:42] >> How this thing is going to be used. So in the event that we have to use this, it implies that the launch vehicle had exploded, had failed, had broke up. [00:15:51] >> Right. [00:15:51] >> Something was happening that triggered an abort. So you had no idea whether or not you're facing down, facing up, falling forward. It's just, you could be at any condition. [00:16:00] >> Yeah. You're talking about -- I don't, I can't even think of a number -- you're talking about a lot of different scenarios-- [00:16:07] >> That's right. [00:16:07] >> And it has to work in all of them. [00:16:09] >> That's right. [00:16:09] >> Interesting, okay. [00:16:10] >> Yeah. [00:16:11] >> So I think you may have addressed this before, but I'm going to come back to it, but, you know, there's a reason that Orion does this move, has the active motor, has the ability to do a front flip. Why did some of the older rockets not need that? Why were they only passive? [00:16:28] >> So some of those engines, they didn't necessarily acquire a, the pitch over portion of the abort, so they-- [00:16:35] >> Okay. [00:16:35] >> Would actually separate, and it was kind of a pointed in a direction, the engines were pointed in a direction to separate you out and away. [00:16:42] >> Oh, so no matter what, it was going away. [00:16:44] >> It was going away. [00:16:45] >> Okay. [00:16:45] >> Right, yeah. So this is a little more intricate, and we have more requirements for it. [00:16:50] >> I see. [00:16:50] >> Yeah. [00:16:51] >> Does it have anything to do with the fact that we are talking about escaping from a much larger, much bigger rocket? [00:16:56] >> No, not necessarily. [00:16:57] >> Very cool. [00:16:57] >> Yeah. [00:16:58] >> So what are some of the challenges of designing an active system? You said, like, there's a lot of computer work that goes into it-- [00:17:04] >> Yeah. [00:17:04] >> But what are some of the things that you've encountered? [00:17:07] >> Be, the portion that I told you about, like designing for Murphy's law. [00:17:10] >> Oh, yeah. [00:17:10] >> It's, you just, we end up using a lot of time to run simulations for all of these contingency scenarios that we would otherwise, you know, it's hard to say what will go wrong, so we just design for everything. [00:17:23] >> Yeah, yeah. [00:17:24] >> So it's quite complex to make sure that, oh, I have this great idea for design. You put it in. It's like, oh, okay, that's great, but it only works in this small region. It has to work for-- [00:17:33] >> Yeah. A bunch of different scenarios-- [00:17:35] >> Yeah. [00:17:35] >> That can happen-- [00:17:36] >> That's right. [00:17:36] >> Up to 300,000 feet, right? [00:17:38] >> Yeah. [00:17:38] >> So you got to think of everything in that space. [00:17:40] >> Yeah. And to take it away from technical -- you'd appreciate this -- another challenge of working on a launch abort system, so I've been at NASA full time for over six years now-- [00:17:50] >> Okay. [00:17:50] >> And this is kind of my main project, and I've done some other work on some other vehicles. But the Orion launch abort system has been my main project. So for six years of my full-time experience here at NASA, I've worked on something -- it's weird to say -- but I'm working on something that I hope never flies-- [00:18:06] >> Oh, yeah. [00:18:07] >> Because if we ever had to use this thing, it implies that, like I said, the launch vehicle-- [00:18:11] >> That something-- [00:18:12] >> We lost the mission-- [00:18:14] >> Went wrong. [00:18:14] >> And you're putting the crew's life in jeopardy. It's nothing you want to -- even if it succeeded, it-- [00:18:20] >> Yes. [00:18:20] >> The mission's failed, and now we have to figure out what happened on the launch vehicle. So it's never going to be a good day when we have to ever use it, so any mission that we have in the future, I'm going to be happen that we didn't fly it. [00:18:33] >> But, I mean, what you're saying makes sense because you just said, you know, there's so many different scenarios that could happen, so-- [00:18:38] >> Yeah. [00:18:38] >> What's the thing that you have control over? Let's just over engineer it. [laughs] Let's design for everything, and that's your responsibility, and it's a big one, right, because-- [00:18:46] >> Yeah. [00:18:47] >> You hope it never flies, and that's a good way of saying it. [00:18:50] >> Yeah. [00:18:50] >> Absolutely, because that means we're doing everything perfectly. Thumbs up. A-okay. But if it does, then you know this thing is going to work. [00:18:58] >> That's right. [00:18:59] >> Yeah. [00:18:59] >> Which is why I'm really excited for not actually flying this with humans on board but preplanned flight tests where you actually do perform an abort to test all that capability without humans on board. [00:19:09] >> Oh, okay. [00:19:10] >> Yeah, so we actually, before I started, we actually did that in 2010. We did a pad abort. So a pad abort is where it's just sitting, replicating it sitting on the pad, and then performing an abort not, while not on top of the launch vehicle. [00:19:25] >> I see. [00:19:26] >> Yeah. [00:19:26] >> Okay, so you just set, in this scenario, you just set the launch abort system-- [00:19:31] >> On the ground, essentially. [00:19:31] >> On the ground. [00:19:32] >> That's right. [00:19:32] >> And just test it to see if it would work at zero, you know-- [00:19:35] >> Yeah. [00:19:35] >> Like if the rocket was just there sitting, hasn't launched yet, and -- so how'd that go? How'd that-- [00:19:41] >> Fantastic test-- [00:19:42] >> All right. [00:19:42] >> From all the people I've talked to that were there and looking at all the design data after the fact, videos -- there are tons of great videos on the NASA website and YouTube-- [00:19:51] >> Yeah, yeah. [00:19:52] >> Perfect test. Everything went well, and the design's kind of matured a little bit since then, but we kind of still do the same thing where we, it's great video. You can see that front flip I was talking about [laughs] to kind of get a better understanding of what I'm talking about in terms of what's going on. [00:20:07] >> So was it -- going back to, is it just the launch abort system, or was there an Orion capsule-- [00:20:14] >> Oh, yeah. [00:20:14] >> Mock up? [00:20:14] >> Yeah, there was a boilerplate Orion capsule under there. [00:20:17] >> Nice. [00:20:17] >> Didn't necessarily have the avionics for anything on there-- [00:20:19] >> Okay. [00:20:20] >> Or any of the peripherals, like the crew life support system. [00:20:24] >> Yeah. [00:20:24] >> But it was a boilerplate capsule that basically weighed about the same as the crew module would when you put humans on board. [00:20:32] >> Makes sense, right? You want a test that's actually-- [00:20:33] >> Yeah, yeah. I mean-- [00:20:33] >> Going to be able to pull that weight at a certain speed. [00:20:34] >> Yeah, you absolutely, and the crew module weighs about like 300, or 30,000 pounds, so you want to make sure that you're, [laughs] that weight is there. [00:20:42] >> Yeah, yeah. Absolutely. That's something you don't want to just say-- [00:20:45] >> You just say-- [00:20:45] >> Oh, we'll just assume. Yeah. [00:20:47] >> Right. [00:20:47] >> [laughs] Awesome. I have seen that video before, and it is super cool, especially the, I don't what, if it's called super-slow motion, but they do have one-- [00:20:55] >> Yep. [00:20:55] >> Where it just, it fires, and you see those engines firing, and then the screen for a full second just goes like, it goes black a little bit, right. [00:21:03] >> Yeah. [00:21:03] >> So you just see, like, it's so bright that the camera is adjusting its exposure. And it's like, whoa. And it goes bright, black for just a second and then shoots straight up. [00:21:12] >> Yeah. [00:21:12] >> It's super cool. [00:21:13] >> I know exactly what part you're talking about. [00:21:15] >> Yeah. [00:21:15] >> And next time you're watching that slow-motion video and while they're going through the pitch over maneuver, I'm sorry, the reorientation maneuver where they're actually doing that flip-- [00:21:24] >> Yeah, yeah. [00:21:25] >> Put, like, ballet or classical music in your head, [laughs] and that's kind of why I [laughter] feel like that. [00:21:30] >> [inaudible] ballet. [00:21:30] >> It's, yeah, it's just this thing flying through the air, and it's-- [00:21:34] >> Dun, dun. [00:21:35] >> Yeah. Yeah. [00:21:35] >> All right, okay. [00:21:36] >> And that's kind of why, every time I [inaudible], that's what I think in my head, but that's just me. [00:21:40] >> Very cool. Awesome. Yeah, I'm definitely going to, definitely, we'll see -- do you know where on the website it is, where we can actually point some folks to to go listen to it? And what's the test called? Maybe they can just search it. [00:21:52] >> Sure, that's the easiest way. NASA videos that are on YouTube is the easiest way. [00:21:56] >> Yeah. [00:21:56] >> It's Pad Abort 1. [00:21:57] >> Pad Abort 1. [00:21:58] >> Yep. [00:21:58] >> Okay, everyone. [00:21:59] >> And it was in 2010. [00:22:00] >> Okay. Pad Abort 1 back in 2010. [00:22:02] >> That's right. [00:22:03] >> Awesome. So what have you done since 2010 that you said there's been some changes? [00:22:07] >> There's been some minor changes to, oh, both the hardware and the software. [00:22:12] >> I see. [00:22:12] >> But ever since I've started, we're gearing up for the next portion of the testing phase, which is actually putting the Orion, some boilerplate Orion capsule, the launch abort system, on a booster -- not necessarily the entire rocket -- but some booster, begin an ascent on the booster, and then perform an abort from that flight mission. So doing an abort as opposed to from the pad in, while the vehicle's moving. [00:22:38] >> A rocket on a rocket. [00:22:39] >> A rocket on a rocket. That's right. [00:22:40] >> Cool. When's that one scheduled for? [00:22:42] >> April 2019 is the current time frame. [00:22:44] >> Okay. [00:22:45] >> Yeah. [00:22:45] >> All right. Do you know what kind of rocket you're going to be using? [00:22:47] >> Yeah. It's a, it's just a booster that's being designed by Orbital ATK. [00:22:51] >> I see. [00:22:51] >> Yeah. [00:22:51] >> Okay. [00:22:51] >> It's an abort test booster. Just a custom rocket. [00:22:54] >> Custom rocket just for this. They're very cool. [00:22:55] >> Yeah. Nothing that's going to take you to space. [00:22:58] >> Yeah, but just because, you know, you have to test actually [laughs] escaping-- [00:23:02] >> Right. [00:23:03] >> From a speeding rocket. [00:23:04] >> Right. [00:23:04] >> I can understand that. That's pretty cool. [00:23:05] >> Yeah. So that's at, for me, that is the exciting flight test where I want to see this actually get used, and work, and, yeah, that'll be cool. [00:23:13] >> Yeah, that will be amazing. [00:23:14] >> Yeah. [00:23:14] >> That's awesome. So there's another one too, right? Are, is there, where, you know, the, we're talking about this in 2019. Is the launch abort system going to be part of EM-1, or EM-2, or anything like that? [00:23:29] >> Anytime there's crew on board, it will absolutely be on there. [00:23:33] >> Crew on board. [00:23:33] >> Yes, yeah. [00:23:33] >> Okay. [00:23:34] >> So for EM-1 is currently, as of recently, not a crew mission. [00:23:39] >> Okay, yeah. [00:23:39] >> So the launch abort system will not be used on that because we have no purpose for using it. [00:23:43] >> I see. [00:23:44] >> But for EM-2, when the crew is on there, absolutely, yeah. [00:23:46] >> Yes. [00:23:47] >> We will not be flying a crew without [laughs] an abort mechanism-- [00:23:49] >> Very cool. [00:23:50] >> Just because spaceflight is hard, and you can't design for everything. You just, it's-- [00:23:54] >> Yeah. [00:23:54] >> We have to make sure that we have -- the crew safety is top priority in spaceflight. [00:23:59] >> So EM-1, we keep referring to that -- I try to stay away from acronyms on the show, but-- [00:24:03] >> Sure. [00:24:04] >> We'll go back to it. It's Exploration Mission 1, right? [00:24:06] >> That's right. [00:24:06] >> That's where we're actually going to put Orion on top of the space launch system-- [00:24:10] >> That's right. [00:24:10] >> And test out to make sure everything's okay. And that one actually goes to the Moon, right? [00:24:14] >> That's right, yeah. It does. [00:24:15] >> Yeah. [00:24:15] >> It's going to circle around the Moon and come back, so-- [00:24:17] >> Yeah. It's going to go really far past the Moon too when it circles around. [00:24:20] >> That's right, yep. [00:24:21] >> It's going to be some good imagery. [00:24:22] >> Yeah, so it's, it'll be an exciting time for the first time we have some human-rated vehicle going out towards the Moon and coming back. [00:24:30] >> Yeah, first time in a long time. That's going to be awesome, yeah. [00:24:33] >> Very awesome, yes. [laughs] I agree. [00:24:34] >> And EM-2 is going to be later, but we're actually going to put a crew aboard, and they're going to do sort of the same thing, right? [00:24:40] >> That's right. [00:24:40] >> They're going to go around the Moon, and-- [00:24:41] >> Yeah. [00:24:42] >> Yeah. That'll be a great mission to do. So just Orion in general, obviously, you know, you're, when we talk about this, the reason that I'm excited about this episode, just besides learning about this really cool technology -- a rocket on a rocket just sounds so cool -- but the idea that each part of the rocket has so much intricate detail that needs to be paid attention to. [00:25:03] >> Yeah. [00:25:03] >> You know, you're talking about the launch abort system, Orion service module. All these different parts have to come together just right to make the whole thing. So, you know, what are some of the challenges for Orion for the capsule but also the whole system, the whole idea of space launch system and going farther and deeper into space than ever before? [00:25:27] >> Yeah. You kind of, as you were listening to all those things, in my head, I'm thinking about, who are our partners through, in the design process for building this, some of this hardware? And that's probably the most challenging thing. Like, the service modules being built by the European Space Agency. The crew modules being built here, but Lockheed has, is the primary contractor. The abort motor engines are being built by Orbital ATK. So there's all of these people that are spread out all across the globe, really-- [00:25:55] >> Yeah, yeah. [00:25:56] >> That are helping to build portions of the space launch system. And even if they are here in the United States, they're spread across the United States. So-- [00:26:04] >> Right. [00:26:05] >> That's one of the biggest challenges, and I deal with this every single day is dealing with and working with people remotely and trying to break those barriers to, you know, having efficient dialogue on a day-to-day basis. So-- [00:26:16] >> Because you're all-- [00:26:16] >> Yeah. [00:26:16] >> Designing stuff for this one idea, right-- [00:26:19] >> Yeah. [00:26:20] >> For a rocket that's going to go into deep space, so you've got to make sure you're talking and got to make sure everyone is on board for what's happening. [00:26:25] >> Absolutely, yeah. [00:26:26] >> Yeah. Makes a lot of sense. Awesome. Wahab, this was such a cool topic. Is there anything else about launch abort system that I may be missing or something that we go dive deeper into? [00:26:36] >> We, so I think we touched upon some of the interesting aspects of it technically. [00:26:42] >> Okay. [00:26:43] >> I guess I can leave you with one little story about, so it's historical testing-- [00:26:48] >> Okay. [00:26:48] >> Just because I find this one fascinating. [00:26:50] >> Oh, yeah. [00:26:52] >> So for the, we're doing our ascent abort test, like I said, in 2019. [00:26:56] >> Right. [00:26:56] >> We also did ascent abort tests in, for the Apollo era missions, so this test is going to be very similar to that, so we designed some custom booster in the 1960's to test the launch abort system. [00:27:08] >> Okay. [00:27:08] >> So when we were actually going out there for that test, it was I think 1966, the booster fired. So now, you're ascending through the atmosphere. And at some flight condition, the launch abort motor was going to be triggered to test the entire hardware. What actually happened was that something happened with the test booster during the design portion or the manufacturing portion, and the rate gyros were instrumented incorrectly -- upside down or something -- so the booster, as soon as it launched, started spinning, and it started spinning faster, and faster, and faster. [00:27:43] >> Whoa. [00:27:43] >> So instead of triggering an abort at some designated altitude, we actually had a real abort on an abort test [laughs] because the launch vehicle actually ended up breaking apart. [00:27:53] >> How about that? [00:27:53] >> Yeah, so that is the best test that you can actually have for this flight system. [00:27:58] >> So it worked, right? [00:27:59] >> It absolutely worked, yeah. [00:28:00] >> Because it did its job. It-- [00:28:01] >> That's right. [00:28:01] >> The rocket did something crazy-- [00:28:03] >> Exactly. [00:28:04] >> And it did its job. That's fantastic. [00:28:06] >> Yes, that's like another example of that was not the intent of that test. The intent was not to actually replicate a launch vehicle failure, but that's what we got. And the system performed admirably. [00:28:15] >> Wow. [00:28:16] >> Yeah. [00:28:16] >> I love that story. [laughs] [00:28:17] >> It's just a, yeah, it's, I hope that that doesn't happen for ascent abort test two, but the one that we had was-- [00:28:24] >> Hey, well, if you're over engineering it to deal with, you know, any situation, you know, you should be good to go. [00:28:29] >> Yeah. [00:28:29] >> I think you'll be fine. [00:28:31] >> And that one actually is, there's a great video of that as well on YouTube. That's the Little Joe booster Apollo abort test. [00:28:39] >> Little Joe, all right. I'm going to mention that again once we -- Little Joe booster, Apollo. [00:28:44] >> Yeah. [00:28:44] >> That's amazing. So cool. All right, Wahab, this was so cool. Thank you so much for coming on the show. For our listeners, if you want to stay tuned until after the music, we're going to tell you, we'll reference some of the videos that Wahab shared with us today so you can go watch them, a little bit more on how you can ask questions and be a part of this conversation. So Wahab, thanks again for coming on the show. It's been an absolute pleasure. [00:29:08] >> My pleasure as well. [00:29:10] [ Music ] [00:29:35] >> Hey, thanks for sticking around. So today, we talked about Wahab Alshahin about launch abort systems -- literally rockets on top of rockets. Super cool. If you want to know the latest updates of what's going on in that world, Wahab actually works on the Orion program. So if you go to NASA.gov/Orion, you can see all the latest updates there. They're also very active on social media, and we like to cover it on several accounts. You can go to the NASA Johnson Space Center account or the Orion accounts on Facebook, Twitter, and Instagram. Don't worry, they're all verified, so they're very easy to find. Just use the hashtag, #askNASA, or hashtag, #HWHAP, H-W-H-A-P, on your favorite platform and submit an idea, or maybe you have a question about launch abort systems or Orion, and we'll make sure to address it on one of the later podcasts here. This podcast was recorded on July 12th, 2017 thanks to Alex Perryman and John Stoll. And thanks again to Mr. Wahab Alshahin for coming on the show. We'll be back next week.

CAPE CANAVERAL, Fla. – Inside the Neil Armstrong Operations and Checkout Building high bay at NASA's Kennedy Space Center in Florida, members of the Brevard Police and Fire Pipes and Drums lead NASA and Lockheed Martin workers toward the Orion crew module, stacked atop its service module. A ceremony will begin to officially turn over the Orion spacecraft for Exploration Flight Test-1 to Lockheed Martin Ground Operations from Orion Assembly, Integration and Production. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of the Orion is scheduled to launch atop a United Launch Alliance Delta IV Heavy rocket from Cape Canaveral Air Force Station in Florida in December to an altitude of 3,600 miles above the Earth's surface. The two-orbit, four-hour flight test will help engineers evaluate the systems critical to crew safety including the heat shield, parachute system and launch abort system.

Go, Susie; Lawrence, Scott L.; Mathias, Donovan L.; Powell, Ryann

2017-01-01

This report documents a study of the historical safety and reliability trends of U.S. space launch vehicles from 1980 to 2015. The launch data history is examined to determine whether propulsion technology choices drove launch system risk and is used to understand how different propulsion system failures manifested into different failure scenarios. The historical data is processed by launch vehicle stage, where a stage is limited by definition to a single propulsion technology, either liquid or solid. Results are aggregated in terms of failure trends and manifestations as a functions of different propulsion stages. Failure manifestations are analyzed in order to understand the types and frequencies of accident environments in which an abort system for a crewed vehicle would be required to operate.

The safety review and approval process for space nuclear power sources

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bennett, G.L.

1991-01-01

Over the past 30 yr. the U.S. Government has evolved a process for the safety review and launch approval of nuclear power sources (NPSs) proposed for launch into space. This process, which involves a number of governmental agencies, ensures that the various postulated accident scenarios are considered, that the responses of the NPSs to the accident environments are assessed, and that appropriate elements of the Federal Government are involved in the launch approval. This process has worked very well in the successful launches of 37 radioisotope thermoelectric generators and 1 reactor by the United States since 1961. Particular attention willmore » be focused on the recent launch of the Galileo spacecraft. 19 refs., 12 figs., 4 tabs.« less

Abort Options for Human Missions to Earth-Moon Halo Orbits

NASA Technical Reports Server (NTRS)

Jesick, Mark C.

2013-01-01

Abort trajectories are optimized for human halo orbit missions about the translunar libration point (L2), with an emphasis on the use of free return trajectories. Optimal transfers from outbound free returns to L2 halo orbits are numerically optimized in the four-body ephemeris model. Circumlunar free returns are used for direct transfers, and cislunar free returns are used in combination with lunar gravity assists to reduce propulsive requirements. Trends in orbit insertion cost and flight time are documented across the southern L2 halo family as a function of halo orbit position and free return flight time. It is determined that the maximum amplitude southern halo incurs the lowest orbit insertion cost for direct transfers but the maximum cost for lunar gravity assist transfers. The minimum amplitude halo is the most expensive destination for direct transfers but the least expensive for lunar gravity assist transfers. The on-orbit abort costs for three halos are computed as a function of abort time and return time. Finally, an architecture analysis is performed to determine launch and on-orbit vehicle requirements for halo orbit missions.

Key to Prevention of Bradycardia: Be Relax Postoperatively: A Case Report.

PubMed

Chowdhury, Tumul; Schaller, Bernhard

2016-05-01

Hypotension and bradycardia are commonly observed after the spinal anesthesia and various mechanisms have been postulated for these hemodynamic changes.A middle-aged otherwise healthy male Caucasian patient developed several episodes of bradycardia postoperatively after the umbilical hernia repair under subarachnoid block (SAB) while trying to lean forward and move his legs. Episodes were aborted when patient was advised to relax in supine position.The common mechanism of bradycardia and hypotension under SAB is postulated as sympathetic blockade, decrease venous return, and parasympathetic over-dominance leading to a decrease in right arterial pressure and pressure in the great veins as they enter the right atrium. But over time, the parasympathetic inhibition is usually withdrawn first, leading to the risk of severe bradycardia that is probably favored by the reverse Trendelenburg position as described in our case.Postoperative severe hemodynamic changes can occur even under stable spinal anesthesia; however, can be prevented by vigilant monitoring and simple maneuver which includes maintenance of relax posture on the bed.

Grid Fin Stabilization of the Orion Launch Abort Vehicle

NASA Technical Reports Server (NTRS)

Pruzan, Daniel A.; Mendenhall, Michael R.; Rose, William C.; Schuster, David M.

2011-01-01

Wind tunnel tests were conducted by Nielsen Engineering & Research (NEAR) and Rose Engineering & Research (REAR) in conjunction with the NASA Engineering & Safety Center (NESC) on a 6%-scale model of the Orion launch abort vehicle (LAV) configured with four grid fins mounted near the base of the vehicle. The objectives of these tests were to 1) quantify LAV stability augmentation provided by the grid fins from subsonic through supersonic Mach numbers, 2) assess the benefits of swept grid fins versus unswept grid fins on the LAV, 3) determine the effects of the LAV abort motors on grid fin aerodynamics, and 4) generate an aerodynamic database for use in the future application of grid fins to small length-to-diameter ratio vehicles similar to the LAV. The tests were conducted in NASA Ames Research Center's 11x11-foot transonic wind tunnel from Mach 0.5 through Mach 1.3 and in their 9x7-foot supersonic wind tunnel from Mach 1.6 through Mach 2.5. Force- and moment-coefficient data were collected for the complete vehicle and for each individual grid fin as a function of angle of attack and sideslip angle. Tests were conducted with both swept and unswept grid fins with the simulated abort motors (cold jets) off and on. The swept grid fins were designed with a 22.5deg aft sweep angle for both the frame and the internal lattice so that the frontal projection of the swept fins was the same as for the unswept fins. Data from these tests indicate that both unswept and swept grid fins provide significant improvements in pitch stability as compared to the baseline vehicle over the Mach number range investigated. The swept fins typically provide improved stability as compared to the unswept fins, but the performance gap diminished as Mach number was increased. The aerodynamic performance of the fins was not observed to degrade when the abort motors were turned on. Results from these tests indicate that grid fins can be a robust solution for stabilizing the Orion LAV over a wide range of operating conditions.

Design, Development and Test Challenges: Separation Mechanisms for the Orion Pad Abort-1 Flight Test

NASA Technical Reports Server (NTRS)

Dinsel, Alison; Morrey, Jeremy M.; OMalley, Patrick; Park, Samuel

2011-01-01

On May 6, 2010, NASA launched the first successful integrated flight test, Pad Abort-1, of the Orion Project from the White Sands Missile Range in Las Cruces, New Mexico. This test demonstrated the ability to perform an emergency pad abort of a full-scale 4.8 m diameter, 8200 kg crew capsule. During development of the critical separation mechanisms for this flight test, various challenges were overcome related to environments definition, installation complications, separation joint retraction speed, thruster ordnance development issues, load path validation and significant design loads increases. The Launch Abort System retention and release (LAS R&R) mechanism consisted of 6 discrete structural connections between the LAS and the crew module (CM) simulator, each of which had a preloaded tension tie, Superbolt torque-nut and frangible nut. During the flight test, the frangible nuts were pyrotechnically split, permitting the CM to separate from the LAS. The LAS separation event was the driving case in the shock environment for many co-located hardware items. During development testing, it was necessary to measure the source shock during the separation event so the predicted shock environment could be validated and used for certification testing of multiple hardware items. The Lockheed Martin test team measured the source separation shock due to the LAS R&R function, which dramatically decreased the predicted environment by 90% at 100 Hz. During development testing a hydraulic tensioner was used to preload the joint; however, the joint relaxation with the tensioner proved unsatisfactory so the design was modified to include a Superbolt torque-nut. The observed preload creep during lab testing was 4% after 30 days, with 2.5% occurring in the first 24 hours. The conversion of strain energy (preload) to kinetic energy (retraction) was measured to be 50-75%. Design features and careful monitoring of multiple strain gauges on each tension tie allowed a pure tensile load to be applied after stacking at the launch pad. Following installation, preload in each joint was monitored for 24 hours. Due to unforeseen complications and the influence of temperature on the portable data acquisition system, the team encountered difficulty in tracking the joint relaxation. In some cases, bond-line failure of the strain gauges occurred.

Space Shuttle Ascent Flight Design Process: Evolution and Lessons Learned

NASA Technical Reports Server (NTRS)

Picka, Bret A.; Glenn, Christopher B.

2011-01-01

The Space Shuttle Ascent Flight Design team is responsible for defining a launch to orbit trajectory profile that satisfies all programmatic mission objectives and defines the ground and onboard reconfiguration requirements for this high-speed and demanding flight phase. This design, verification and reconfiguration process ensures that all applicable mission scenarios are enveloped within integrated vehicle and spacecraft certification constraints and criteria, and includes the design of the nominal ascent profile and trajectory profiles for both uphill and ground-to-ground aborts. The team also develops a wide array of associated training, avionics flight software verification, onboard crew and operations facility products. These key ground and onboard products provide the ultimate users and operators the necessary insight and situational awareness for trajectory dynamics, performance and event sequences, abort mode boundaries and moding, flight performance and impact predictions for launch vehicle stages for use in range safety, and flight software performance. These products also provide the necessary insight to or reconfiguration of communications and tracking systems, launch collision avoidance requirements, and day of launch crew targeting and onboard guidance, navigation and flight control updates that incorporate the final vehicle configuration and environment conditions for the mission. Over the course of the Space Shuttle Program, ascent trajectory design and mission planning has evolved in order to improve program flexibility and reduce cost, while maintaining outstanding data quality. Along the way, the team has implemented innovative solutions and technologies in order to overcome significant challenges. A number of these solutions may have applicability to future human spaceflight programs.

Ares I-X: On the Threshold of Exploration

NASA Technical Reports Server (NTRS)

Davis, Stephan R.; Askins, Bruce

2009-01-01

Ares I-X, the first flight of the Ares I crew launch vehicle, is less than a year from launch. Ares I-X will test the flight characteristics of Ares I from liftoff to first stage separation and recovery. The flight also will demonstrate the computer hardware and software (avionics) needed to control the vehicle; deploy the parachutes that allow the first stage booster to land in the ocean safely; measure and control how much the rocket rolls during flight; test and measure the effects of first stage separation; and develop and try out new ground handling and rocket stacking procedures in the Vehicle Assembly Building (VAB) and first stage recovery procedures at Kennedy Space Center (KSC) in Florida. All Ares I-X major elements have completed their critical design reviews, and are nearing final fabrication. The first stage--four-segment solid rocket booster from the Space Shuttle inventory--incorporates new simulated forward structures to match the Ares I five-segment booster. The upper stage, Orion crew module, and launch abort system will comprise simulator hardware that incorporates developmental flight instrumentation for essential data collection during the mission. The upper stage simulator consists of smaller cylindrical segments, which were transported to KSC in fall 2008. The crew module and launch abort system simulator were shipped in December 2008. The first stage hardware, active roll control system (RoCS), and avionics components will be delivered to KSC in 2009. This paper will provide detailed statuses of the Ares I-X hardware elements as NASA's Constellation Program prepares for this first flight of a new exploration era in the summer of 2009.

STS-51 pad abort. OV103-engine 2033 (ME-2) fuel flowmeter sensor open circuit

NASA Technical Reports Server (NTRS)

1993-01-01

The STS-51 initial launch attempt of Discovery (OV-103) was terminated on KSC launch pad 39B on 12 Aug. 1993 at 9:12 AM E.S.T. due to a sensor redundancy failure in the liquid hydrogen system of ME-2 (Engine 2033). The event description and time line are summarized. Propellant loading was initiated on 12 Aug. 1993 at 12:00 AM EST. All space shuttle main engine (SSME) chill parameters and Launch Commit Criteria (LCC) were nominal. At engine start plus 1.34 seconds a Failure Identification (FID) was posted against Engine 2033 for exceeding the 1800 spin intra-channel (A1-A2) Fuel Flowrate sensor channel qualification limit. The engine was shut down at 1.50 seconds followed by Engines 2032 and 2030. All shut down sequences were nominal and the mission was safely aborted. SSME Avionics hardware and software performed nominally during the incident. A review of vehicle data table (VDT) data and controller software logic revealed no failure indications other than the single FID 111-101, Fuel Flowrate Intra-Channel Test Channel A disqualification. Software logic was executed according to requirements and there was no anomalous controller software operation. Immediately following the abort, a Rocketdyne/NASA failure investigation team was assembled. The team successfully isolated the failure cause to an open circuit in a Fuel Flowrate Sensor. This type of failure has occurred eight previous times in ground testing. The sensor had performed acceptably on three previous flights of the engine and SSME flight history shows 684 combined fuel flow rate sensor channel flights without failure. The disqualification of an Engine 2 (SSME No. 2033) Fuel Flowrate sensor channel was a result of an instrumentation failure and not engine performance. All other engine operations were nominal. This disqualification resulted in an engine shutdown and safe sequential shutdown of all three engines prior to ignition of the solid boosters.

The Orion crew module will be stacked on the service module in the FAST cell and then both modules will be put through their final system tests for Exploration Flight Test-1, or EFT-1, prior to rolling out of the facility for integration with the United Launch Alliance Delta IV Heavy rocket. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of Orion, EFT-1, is scheduled to launch later this year atop a Delta IV rocket from Cape Canaveral Air Force Station in Florida to an altitude of 3,600 miles above the Earth's surface. The two-orbit, four-hour flight test will help engineers evaluate the systems critical to crew safety including the heat shield, parachute system and launch abort system.

A Review of the MLAS Parachute Systems

NASA Technical Reports Server (NTRS)

Taylor, Anthony P.; Kelley, Christopher; Magner, Eldred; Peterson, David; Hahn, Jeffrey; Yuchnovicz, Daniel E.

2009-01-01

The NASA Engineering and Safety Center (NESC) is developing the Max Launch Abort System (MLAS) as a risk-mitigation design should problems arise with the baseline Orion spacecraft launch abort design. The Max in MLAS is dedicated to Max Faget, the renowned NASA spacecraft designer. The MLAS flight test vehicle consists of boost skirt, coast skirt and the MLAS fairing which houses a full scale boilerplate Orion Crew Module (CM). The objective of the flight test is to prove that the CM can be released from the MLAS fairing during pad abort conditions without detrimental recontact between the CM and fairing, achieving performance similar to the Orion launch abort system. The boost and coast skirts provide the necessary thrust and stability to achieve the flight test conditions and are released prior to the test -- much like the Little Joe booster was used in the Apollo Launch Escape System tests. To achieve the test objective, two parachutes are deployed from the fairing to reorient the CM/fairing to a heatshield first orientation. The parachutes then provide the force necessary to reduce the total angle of attack and body angular rates required for safe release of the CM from the fairing. A secondary test objective after CM release from the fairing is to investigate the removal of the CM forward bay cover (FBC) with CM drogue parachutes for the purpose of attempting to synchronously deploying a set of CM main parachutes. Although multiple parachute deployments are used in the MLAS flight test vehicle to complete its objective, there are only two parachute types employed in the flight test. Five of the nine parachutes used for MLAS are 27.6 ft D(sub 0) ribbon parachutes, and the remaining four are standard G-12 cargo parachutes. This paper presents an overview of the 27.6 ft D(sub 0) ribbon parachute system employed on the MLAS flight test vehicle for coast skirt separation, fairing reorientation, and as drogue parachutes for the CM after separation from the fairing. Discussion will include: the process used to select this design, previously proven as a spin/stall recovery parachute; descriptions of all components of the parachute system; the minor modifications necessary to adapt the parachute to the MLAS program; the techniques used to analyze the parachute for the multiple roles it performs; a discussion of the rigging techniques used to interface the parachute system to the vehicle; and a brief description of how the evolution of the program affected parachute usage and analysis. An overview of the Objective system, rationale for the MLAS approach and the future of the program will also be presented. We hope to have flight test results to report at the time of the Conference Presentation.

Simulation and Analysis of Launch Teams (SALT)

NASA Technical Reports Server (NTRS)

2008-01-01

A SALT effort was initiated in late 2005 with seed funding from the Office of Safety and Mission Assurance Human Factors organization. Its objectives included demonstrating human behavior and performance modeling and simulation technologies for launch team analysis, training, and evaluation. The goal of the research is to improve future NASA operations and training. The project employed an iterative approach, with the first iteration focusing on the last 70 minutes of a nominal-case Space Shuttle countdown, the second iteration focusing on aborts and launch commit criteria violations, the third iteration focusing on Ares I-X communications, and the fourth iteration focusing on Ares I-X Firing Room configurations. SALT applied new commercial off-the-shelf technologies from industry and the Department of Defense in the spaceport domain.

Space Shuttle guidance for multiple main engine failures during first stage

NASA Technical Reports Server (NTRS)

Sponaugle, Steven J.; Fernandes, Stanley T.

1987-01-01

This paper presents contingency abort guidance schemes recently developed for multiple Space Shuttle main engine failures during the first two minutes of flight (first stage). The ascent and entry guidance schemes greatly improve the possibility of the crew and/or the Orbiter surviving a first stage contingency abort. Both guidance schemes were required to meet certain structural and controllability constraints. In addition, the systems were designed with the flexibility to allow for seasonal variations in the atmosphere and wind. The ascent scheme guides the vehicle to a desirable, lofted state at solid rocket booster burnout while reducing the structural loads on the vehicle. After Orbiter separation from the solid rockets and the external tank, the entry scheme guides the Orbiter through one of two possible entries. If the proper altitude/range/velocity conditions have been met, a return-to-launch-site 'Split-S' maneuver may be attempted. Otherwise, a down-range abort to an equilibrium glide and subsequent crew bailout is performed.

Projects: (1) Boeing Launch Abort Analysis My first project for the summer was analyzing the Boeing CCDev Vehicle's abort aerodynamics using an inviscid solver (CART3D). The goal of the project was to develop the grid and CFD inputs necessary to use CART3D as a quick tool for investigating loading trends at various points along abort trajectories. As a supplementary task, I analyzed a few cases and compared them to the aerodatabase from the last generation geometry. (2) My second project for the summer dealt with investigating how heating changes as the height of a protuberance on top of a flat plate changes. The goal of this investigation is to better understand how to properly model heating on and around a protuberance. This is one of the biggest challenges when designing a re ]entry vehicle because very small changes in the shape and conditions leading up to a protuberance, not to mention the protuberance geometry, will greatly impact the local heating.

2003-01-01

The Lockheed Martin Orbital Space Plane System provides crew transfer and rescue for the International Space Station more safely and affordably than current human space transportation systems. Through planned upgrades and spiral development, it is also capable of satisfying the Nation's evolving space transportation requirements and enabling the national vision for human space flight. The OSP System, formulated through rigorous requirements definition and decomposition, consists of spacecraft and launch vehicle flight elements, ground processing facilities and existing transportation, launch complex, range, mission control, weather, navigation, communication and tracking infrastructure. The concept of operations, including procurement, mission planning, launch preparation, launch and mission operations and vehicle maintenance, repair and turnaround, is structured to maximize flexibility and mission availability and minimize program life cycle cost. The approach to human rating and crew safety utilizes simplicity, performance margin, redundancy, abort modes and escape modes to mitigate credible hazards that cannot be designed out of the system.

Koch's postulates, carnivorous cows, and tuberculosis today.

PubMed

Tabrah, Frank L

2011-07-01

With Koch's announcement in 1882 of his work with the tubercle bacillus, his famous postulates launched the rational world of infectious disease and an abrupt social change--strict patient isolation. The postulates, so successful at their inception, soon began to show some problems, particularly with cholera, which clearly violated some of Koch's requirements. Subsequent studies of other diseases and the discovery of entirely new ones have so altered and expanded the original postulates that they now are little but a precious touch of history. The present additions and replacements of the original concepts are skillful changes that several authors have devised to introduce new order into understanding complex viral and prion diseases. In 1988, this knowledge, with the totally rational response of the British population and its cattle industry, was critical in promptly blocking the threatened epidemic of human prion disease. In contrast, the recent upsurge of tuberculosis (TB) in the worldwide AIDS epidemic in developing countries, and the sudden increase in metabolic syndrome in wealthy ones, suggests the need for focused sociobiologic research seeking ways to affect the damaging lifestyle behavior of many less educated populations in both settings. The world awaits an equivalent of Koch's Postulates in sociobiology to explain and possibly avert large self-destructive behaviors.

Family planning is reducing abortions.

PubMed

Clinton, H R

1997-01-01

This news brief presents the US President's wife's statement on the association between use of family planning and a decline in abortions worldwide. Hillary Rodham Clinton attended the Sixth Conference of Wives of Heads of State and Government of the Americas held in La Paz, Bolivia. The conference was suitably located in Bolivia, a country with the highest rates of maternal mortality in South America. Bolivia has responded by launching a national family planning campaign coordinated between government, nongovernmental, and medical organizations. Half of Bolivian women experience pregnancy and childbirth without the support of trained medical staff. Mortality from abortion complications account for about half of all maternal deaths in Bolivia. Voluntary family planning workers teach women about the benefits of child spacing, breast feeding, nutrition, prenatal and postpartum care, and safe deliveries. Bolivia has succeeded in increasing its contraceptive use rates and decreasing the number of safe and unsafe abortions. Bolivia's program effort was supported by USAID. USAID provided technical assistance and funds for the establishment of a network of primary health care clinics. Mrs. Clinton visited one such clinic in a poor neighborhood in La Paz, which in its first six months of operation provided 2200 consultations, delivered 200 babies, registered 700 new family planning users, and immunized 2500 children. Clinics such as this one will be affected by the US Congress's harsh cuts in aid, which reduce funding by 35% and delay program funding by 9 months. These US government cuts in foreign aid are expected to result in an additional 1.6 million abortions, over 8000 maternal deaths, and 134,000 infant deaths in developing countries. An investment in population assistance represents a sensible, cost-effective, and long-term strategy for improving women's health, strengthening families, and reducing abortion.

Sammons, Matthew; Powell, Cory; Pellicciotti, Joseph; Buehrle, Ralph; Johnson, Keith

2012-01-01

The Crew Exploration Vehicle (CEV) was intended to be the next-generation human spacecraft for the Constellation Program. The CEV Isolator Strut mechanism was designed to mitigate loads imparted to the CEV crew caused by the Thrust Oscillation (TO) phenomenon of the proposed Ares I Launch Vehicle (LV). The Isolator Strut was also designed to be compatible with Launch Abort (LA) contingencies and landing scenarios. Prototype struts were designed, built, and tested in component, sub-system, and system-level testing. The design of the strut, the results of the tests, and the conclusions and lessons learned from the program will be explored in this paper.

Evaluation of the Space Shuttle Transatlantic Abort Landing Atmospheric Sounding System

NASA Technical Reports Server (NTRS)

Leahy, Frank B.

2003-01-01

A study was conducted to determine the quality of thermodynamic and wind data measured by or derived from the Transatlantic Abort Landing (TAL) Atmospheric Sounding System (TASS). The system has Global Positioning System (GPS) tracking capability and includes a helium-filled latex balloon that carries an instrument package (sonde) and various ground equipment that receives and processes the data from the sonde. TASS is used to provide vertical profiles of thermodynamic and low-resolution wind data in support of Shuttle abort landing operations at TAL sites. TASS uses GPS to determine height, wind speed, and wind direction. The TASS sonde has sensors that directly measure air temperature and relative humidity. These are then used to derive air pressure and density. Test flights were conducted where a TASS sonde and a reference sonde were attached to the same balloon and the two profiles were compared. The objective of the testing was to determine if TASS thermodynamic and wind data met Space Shuttle Program (SSP) accuracy requirements outlined in the Space Shuttle Launch and Landing Program Requirements Document (PRD).

New laws on population urged.

1976-12-03

A workshop on ''Population and the Law'' sponsored by the Family Planning Organization of the Philippines and the International Planned Parenthood Federation recommended the following changes in Philippine law to implement family planning: legalization of abortion for women whose life or health are endangered by pregnancy and those who become pregnant despite contraceptives; delaying age of marriage to 18; extension of family planning incentives and maternity leave to women in government service; allow trained nurses and midwives to dispense contractives; legalize sterilization; include sterilization in medicare benefits; specify by law which contraceptive drugs may be dispensed by nonphysicians and nonpharmacists in rural areas; legalize premarital family planning counseling; declare family planning materials tax exempt; encourage reluctant doctors to practice sterilization through professional regulatory agencies; extend industrial family planning services to women living near the plant; launch massive information drives to advise young people of the hazards of premarital sex; strict enforcement of abortion laws in areas where illegal abortion still exists; grant women equal rights in area of consent for sterilization; and eliminate the stigma of illegitimacy for those born out of wedlock.

Analysis and Results from a Flush Airdata Sensing (FADS) System in Close Proximity to Firing Rocket Nozzles

Ali, Aliyah N.; Borrer, Jerry L.

2013-01-01

This presentation presents information regarding the nose-cap flush airdata sensing (FADS) system on Orion's Pad Abort 1 (PA-1) vehicle. The purpose of the nose-cap FADS system was to test whether or not useful data could be obtained from a FADS system if it was placed in close proximity to firing rockets nozzles like the attitude control motor (ACM) nozzles on the PA-1 launch abort system (LAS). The nose-cap FADS systems use pressure measurements from a series of pressure ports which are arranged in a cruciform pattern and flush with the surface of the vehicle to estimate values of angle of attack, angle of side-slip, Mach number, impact pressure and free-stream static pressure.

CAPE CANAVERAL, Fla. -- The SpaceX Falcon 9 rocket static fire test on Space Launch Complex-40 at Cape Canaveral Air Force Station was aborted at T minus 1.1 seconds due to high engine chamber pressure. During the test, all nine Merlin engines, which use rocket-grade kerosene and liquid oxygen to produce 1 million pounds of thrust, are expected to fire at once. After the test, SpaceX will conduct a thorough review of all data as engineers make final preparations for the first launch of the Commercial Orbital Transportation Services (COTS) Dragon spacecraft to low Earth orbit atop the Falcon 9. This first stage firing is part of a full launch dress rehearsal, which will end after the engines fire at full power for two seconds, with only the hold-down system restraining the rocket from flight.

Trends in selective abortions of girls in India: analysis of nationally representative birth histories from 1990 to 2005 and census data from 1991 to 2011.

2011-06-04

India's 2011 census revealed a growing imbalance between the numbers of girls and boys aged 0-6 years, which we postulate is due to increased prenatal sex determination with subsequent selective abortion of female fetuses. We aimed to establish the trends in sex ratio by birth order from 1990 to 2005 with three nationally representative surveys and to quantify the totals of selective abortions of girls with census cohort data. We assessed sex ratios by birth order in 0·25 million births in three rounds of the nationally representative National Family Health Survey covering the period from 1990 to 2005. We estimated totals of selective abortion of girls by assessing the birth cohorts of children aged 0-6 years in the 1991, 2001, and 2011 censuses. Our main statistic was the conditional sex ratio of second-order births after a firstborn girl and we used 3-year rolling weighted averages to test for trends, with differences between trends compared by linear regression. The conditional sex ratio for second-order births when the firstborn was a girl fell from 906 per 1000 boys (99% CI 798-1013) in 1990 to 836 (733-939) in 2005; an annual decline of 0·52% (p for trend=0·002). Declines were much greater in mothers with 10 or more years of education than in mothers with no education, and in wealthier households compared with poorer households. By contrast, we did not detect any significant declines in the sex ratio for second-order births if the firstborn was a boy, or for firstborns. Between the 2001 and 2011 censuses, more than twice the number of Indian districts (local administrative areas) showed declines in the child sex ratio as districts with no change or increases. After adjusting for excess mortality rates in girls, our estimates of number of selective abortions of girls rose from 0-2·0 million in the 1980s, to 1·2-4·1 million in the 1990s, and to 3·1-6·0 million in the 2000s. Each 1% decline in child sex ratio at ages 0-6 years implied 1·2-3·6 million more selective abortions of girls. Selective abortions of girls totalled about 4·2-12·1 million from 1980-2010, with a greater rate of increase in the 1990s than in the 2000s. Selective abortion of girls, especially for pregnancies after a firstborn girl, has increased substantially in India. Most of India's population now live in states where selective abortion of girls is common.

Struggling to survive in Russia.

PubMed

Gadasina, A

1997-01-01

Abortion has long been the traditional method of family planning (FP) in Russia. Today, abortions are free, but contraception is not. The birth rate has decreased between 1989 and 1995, and the death rate has increased. The present economic situation has had a marked adverse effect on women who are expected to juggle jobs, household duties, and child care responsibilities. In order to survive, women sometimes must engage in work that compromises their health. Many women have resorted in prostitution, and this has caused an unprecedented explosion in the incidence of sexually transmitted diseases, especially syphilis. The number of people newly registered as HIV-positive in the first half of 1997 exceeded the total for 1996. While sex education is still restricted, erotica and pornography is widely available. Cases of syphilis are increasing among the young, and, in 1996, about 2500 girls under age 15 gave birth and an equal number had abortions. Only 12% of all pregnant women and 25% of newborn infants can be considered healthy. In 1994, the government launched a FP program that is being carried out by a few public and private organizations. One of these, the Russian FP Association, has created more than 50 branches in different regions, opened youth centers, and provided sex education and reproductive health counseling. The overall effort has led to a 27% reduction in abortions, and a 25% reduction in abortion mortality. These efforts, however, have been opposed by "pro-life" forces and by the Communist wing of the government that reduced the budget. The FP Association is fighting back by lobbying and explaining the need for its work.

Cyclic Cryogenic Thermal-Mechanical Testing of an X-33/RLV Liquid Oxygen Tank Concept

NASA Technical Reports Server (NTRS)

Rivers, H. Kevin

1999-01-01

An important step in developing a cost-effective, reusable, launch vehicle is the development of durable, lightweight, insulated, cryogenic propellant tanks. Current cryogenic tanks are expendable so most of the existing technology is not directly applicable to future launch vehicles. As part of the X-33/Reusable Launch Vehicle (RLV) Program, an experimental apparatus developed at the NASA Langley Research Center for evaluating the effects of combined, cyclic, thermal and mechanical loading on cryogenic tank concepts was used to evaluate cryogenic propellant tank concepts for Lockheed-Martin Michoud Space Systems. An aluminum-lithium (Al 2195) liquid oxygen tank concept, insulated with SS-1171 and PDL-1034 cryogenic insulation, is tested under simulated mission conditions, and the results of those tests are reported. The tests consists of twenty-five simulated Launch/Abort missions and twenty-five simulated flight missions with temperatures ranging from -320 F to 350 F and a maximum mechanical load of 71,300 lb. in tension.

CAPE CANAVERAL, Fla. – Inside the Neil Armstrong Operations and Checkout Building high bay at NASA’s Kennedy Space Center in Florida, Lockheed Martin technicians prepare to do a fit check of the forward bay cover for the Orion crew module. The cover is a shell that fits over Orion's crew module to protect the spacecraft during launch, orbital flight and re-entry into Earth's atmosphere. When Orion returns from space, the cover must be jettisoned high above the ground so that the parachutes can deploy and unfurl. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted flight test of Orion is scheduled to launch in December 2014 atop a United Launch Alliance Delta IV Heavy rocket and in 2018 on NASA’s Space Launch System rocket.

CAPE CANAVERAL, Fla. – The umbilical swing arm for Orion's Exploration Flight Test 1, or EFT-1, has been attached to the uppermost location on the fixed umbilical tower at Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida. All three swing arms on the tower are undergoing tests to confirm that they are operating correctly. The uppermost swing arm will carry umbilicals that will be mated to Orion's launch abort system and environmental control system. During launch, all three umbilicals will pull away from Orion and the United Launch Alliance Delta IV Heavy rocket at T-0. During the EFT-1 mission, Orion will travel farther into space than any human spacecraft has gone in more than 40 years. The data gathered during the flight will influence design decisions, validate existing computer models and innovative new approaches to space systems development, as well as reduce overall mission risks and costs for later Orion flights. Liftoff of Orion on its first flight test is planned for fall 2014. Photo credit: NASA/Daniel Casper

2017-03-14

A team of engineers recently tested a newly installed emergency egress system at Space Launch Complex 41 at Cape Canaveral Air Force Station to prepare for crew launches for NASA’s Commercial Crew Program. Boeing’s CST-100 Starliner spacecraft and United Launch Alliance Atlas V rocket that will boost astronauts to the International Space Station, will have many safety elements built into the systems. The Starliner emergency egress system operates a lot like a zip line, with four egress cables connecting at level 12 of the Crew Access Tower to a landing zone about 1,300 feet away from the launch vehicle. Five individual seats on four separate lines can transport up to 20 people off of the tower in the unlikely event there is an emergency on the launch pad. NASA has partnered with private industry to take astronauts to the space station. Boeing and SpaceX are building their own unique systems that meet NASA safety and mission requirements. The systems also will include launch abort systems and additional controls that astronauts can use during flight to enhance crew safety.

The NASA MLAS Flight Demonstration - A Review of a Highly Successful Test

NASA Technical Reports Server (NTRS)

Taylor, Anthony P.; Kelley, Christopher; Magner, Eldred; Peterson, David; Hahn, Jeffrey; Yuchnovicz, Daniel

2010-01-01

NASA has tested the Max Launch Abort System (MLAS) as a risk-mitigation design should problems arise with the baseline Orion spacecraft launch abort design. The Max in MLAS is not Maximum, but rather dedicated to Max Faget, The renowned NASA Spacecraft designer. In the fall of 2009, the mission was flown, with great success, from the NASA Wallops Flight Facility. The MLAS flight test vehicle prototype consists of a boost ring, coast ring, and the MLAS fairing itself, which houses an Orion Command Module (CM) boilerplate. The objective of the MLAS flight test is to reorient the fairing with the CM, weighing approximately 29,000 lbs and traveling 290 fps, 180 degrees to an orientation suitable for the release of the CM during a pad abort and low altitude abort. Although multiple parachute deployments are used in the MLAS flight test vehicle to complete its objective, there are only two parachute types employed in the flight test. Five of the nine parachutes used for MLAS are 27.6 ft DO ribbon parachutes, and the remaining four are standard G-12 cargo parachutes. This paper presents an overview of the 27.6 ft DO ribbon parachute system employed on the MLAS flight test vehicle for coast ring separation, fairing reorientation, and as drogue parachutes for the CM after separation from the fairing. Discussion will include: the process used to select this design, previously proven as a spin/stall recovery parachute; descriptions of all components of the parachute system; the minor modifications necessary to adapt the parachute to the MLAS program; the techniques used to analyze the parachute for the multiple roles it performs; a discussion of the rigging techniques used to interface the parachute system to the vehicle; a brief description of how the evolution of the program affected parachute usage and analysis; and a summary of the results of the flight test, including video of the flight test and subsequent summary analysis. . A discussion of the flight test which was highly successful as well as the flight test observations will be a significant portion of the review.

Acoustic-Modal Testing of the Ares I Launch Abort System Attitude Control Motor Valve

Davis, R. Benjamin; Fischbach, Sean R.

2010-01-01

The Attitude Control Motor (ACM) is being developed for use in the Launch Abort System (LAS) of NASA's Ares I launch vehicle. The ACM consists of a small solid rocket motor and eight actuated pintle valves that directionally allocate.thrust_- 1t.has-been- predicted-that significant unsteady. pressure.fluctuations.will.exist. inside the-valves during operation. The dominant frequencies of these oscillations correspond to the lowest several acoustic natural frequencies of the individual valves. An acoustic finite element model of the fluid volume inside the valve has been critical to the prediction of these frequencies and their associated mode shapes. This work describes an effort to experimentally validate the acoustic finite model of the valve with an acoustic modal test. The modal test involved instrumenting a flight-like valve with six microphones and then exciting the enclosed air with a loudspeaker. The loudspeaker was configured to deliver broadband noise at relatively high sound pressure levels. The aquired microphone signals were post-processed and compared to results generated from the acoustic finite element model. Initial comparisons between the test data and the model results revealed that additional model refinement was necessary. Specifically, the model was updated to implement a complex impedance boundary condition at the entrance to the valve supply tube. This boundary condition models the frequency-dependent impedance that an acoustic wave will encounter as it reaches the end of the supply tube. Upon invoking this boundary condition, significantly improved agreement between the test data and the model was realized.

CAPE CANAVERAL, Fla. – NASA Administrator Charlie Bolden helps mark the T-6 months and counting to the launch of Orion on Exploration Flight Test-1, or EFT-1, during a visit to the Operations and Checkout Building high bay at NASA's Kennedy Space Center in Florida. The crew module has been stacked on the service module in the Final Assembly and System Testing cell. EFT-1 will provide engineers with data about the heat shield's ability to protect Orion and its future crews from the 4,000-degree heat of reentry and an ocean splashdown following the spacecraft’s 20,000-mph reentry from space. Data gathered during the flight will inform decisions about design improvements on the heat shield and other Orion systems, and authenticate existing computer models and new approaches to space systems design and development. This process is critical to reducing overall risks and costs of future Orion missions. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of the Orion is scheduled to launch later this year atop a Delta IV rocket from Cape Canaveral Air Force Station in Florida to an altitude of 3,600 miles above the Earth's surface. The two-orbit, four-hour flight test will help engineers evaluate the systems critical to crew safety including the heat shield, parachute system and launch abort system.

Conceptual Design For Interplanetary Spaceship Discovery

NASA Astrophysics Data System (ADS)

Benton, Mark G.

2006-01-01

With the recently revived national interest in Lunar and Mars missions, this design study was undertaken by the author in an attempt to satisfy the long-term space exploration vision of human travel ``to the Moon, Mars, and beyond'' with a single design or family of vehicles. This paper describes a conceptual design for an interplanetary spaceship of the not-to-distant future. It is a design that is outwardly similar to the spaceship Discovery depicted in the novel ``2001 - A Space Odyssey'' and film of the same name. Like its namesake, this spaceship could one day transport a human expedition to explore the moons of Jupiter. This spaceship Discovery is a real engineering design that is capable of being implemented using technologies that are currently at or near the state-of-the-art. The ship's main propulsion and electrical power are provided by bi-modal nuclear thermal rocket engines. Configurations are presented to satisfy four basic Design Reference Missions: (1) a high-energy mission to Jupiter's moon Callisto, (2) a high-energy mission to Mars, (3) a low-energy mission to Mars, and (4) a high-energy mission to the Moon. The spaceship design includes dual, strap-on boosters to enable the high-energy Mars and Jupiter missions. Three conceptual lander designs are presented: (1) Two types of Mars landers that utilize atmospheric and propulsive braking, and (2) a lander for Callisto or Earth's Moon that utilizes only propulsive braking. Spaceship Discovery offers many advantages for human exploration of the Solar System: (1) Nuclear propulsion enables propulsive capture and escape maneuvers at Earth and target planets, eliminating risky aero-capture maneuvers. (2) Strap-on boosters provide robust propulsive energy, enabling flexibility in mission planning, shorter transit times, expanded launch windows, and free-return abort trajectories from Mars. (3) A backup abort propulsion system enables crew aborts at multiple points in the mission. (4) Clustered NTR engines provide ``engine out'' redundancy. (5) The design efficiently implements galactic cosmic ray shielding using main propellant liquid hydrogen. (6) The design provides artificial gravity to mitigate crew physiological problems on long-duration missions. (7) The design is modular and can be launched using the proposed upgrades to the Evolved Expendable Launch Vehicles or Shuttle-derived heavy lift launch vehicles. (8) High value modules are reusable for Mars and Lunar missions. (9) The design has inherent growth capability, and can be tailored to satisfy expanding mission requirements to enable an in-family progression ``to the Moon, Mars, and beyond.''

McFarland, Shane M.

2011-01-01

In support of the NASA Constellation Program, a space-suit architecture was envisioned for support of Launch, Entry, Abort, Micro-g EVA, Post Landing crew operations, and under emergency conditions, survival. This space suit architecture is unique in comparison to previous launch, entry, and abort (LEA) suit architectures in that it utilized rigid mobility elements in the scye and the upper arm regions. The suit architecture also employed rigid thigh disconnect elements to allow for quick disconnect functionality above the knee which allowed for commonality of the lower portion of the suit across two suit configurations. This suit architecture was designed to interface with the Orion seat subsystem, which includes seat components, lateral supports, and restraints. Due to this unique configuration of spacesuit mobility elements, combined with the need to provide occupant protection during dynamic landing events, risks were identified with potential injury due to the suit characteristics described above. To address the risk concerns, a test series was developed to evaluate the likelihood and consequences of these potential issues. Testing included use of Anthropomorphic Test Devices (ATDs), Post Mortem Human Subjects (PMHS), and representative seat/suit hardware in combination with high linear acceleration events. The ensuing treatment focuses on detailed results of the testing that has been conducted under this test series thus far.

Simulation Assisted Risk Assessment Applied to Launch Vehicle Conceptual Design

NASA Technical Reports Server (NTRS)

Mathias, Donovan L.; Go, Susie; Gee, Ken; Lawrence, Scott

2008-01-01

A simulation-based risk assessment approach is presented and is applied to the analysis of abort during the ascent phase of a space exploration mission. The approach utilizes groupings of launch vehicle failures, referred to as failure bins, which are mapped to corresponding failure environments. Physical models are used to characterize the failure environments in terms of the risk due to blast overpressure, resulting debris field, and the thermal radiation due to a fireball. The resulting risk to the crew is dynamically modeled by combining the likelihood of each failure, the severity of the failure environments as a function of initiator and time of the failure, the robustness of the crew module, and the warning time available due to early detection. The approach is shown to support the launch vehicle design process by characterizing the risk drivers and identifying regions where failure detection would significantly reduce the risk to the crew.

Concept of Operations for a Prospective "Proving Ground" in the Lunar Vicinity

NASA Technical Reports Server (NTRS)

Love, Stanley G.; Hill, James J.

2016-01-01

NASA is studying a "Proving Ground" near the Moon to conduct human space exploration missions in preparation for future flights to Mars. This paper describes a concept of operations ("conops") for activities in the Proving Ground, focusing on the construction and use of a mobile Cislunar Transit Habitat capable of months-long excursions within and beyond the Earth-Moon system. Key elements in the conops include the Orion spacecraft (with mission kits for docking and other specialized operations) and the Space Launch System heavy-lift rocket. Potential additions include commercial launch vehicles and logistics carriers, solar electric propulsion stages to move elements between different orbits and eventually take them on excursions to deep space, a node module with multiple docking ports, habitation and life support blocks, and international robotic and piloted lunar landers. The landers might include reusable ascent modules which could remain docked to in-space elements between lunar sorties. The architecture will include infrastructure for launch preparation, communication, mission control, and range safety. The conops describes "case studies" of notional missions chosen to guide the design of the architecture and its elements. One such mission is the delivery of a 10-ton pressurized element, co-manifested with an Orion on a Block 1B Space Launch System rocket, to the Proving Ground. With a large solar electric propulsion stage, the architecture could enable a year-long mission to land humans on a near-Earth asteroid. In the last case, after returning to near-lunar space, two of the asteroid explorers could join two crewmembers freshly arrived from Earth for a Moon landing, helping to safely quantify the risk of landing deconditioned crews on Mars. The conops also discusses aborts and contingency operations. Early return to Earth may be difficult, especially during later Proving Ground missions. While adding risk, limited-abort conditions provide needed practice for Mars, from which early return is likely to be impossible.

Assessment of community awareness and risk perceptions of zoonotic causes of abortion in cattle at three selected livestock-wildlife interface areas of Zimbabwe.

A study was conducted to assess the awareness of cattle abortions due to brucellosis, Rift Valley fever (RVF) and leptospirosis, and to compare frequencies of reported abortions in communities living at the periphery of the Great Limpopo Transfrontier Conservation Area in southeastern Zimbabwe. Three study sites were selected based on the type of livestock-wildlife interface: porous livestock-wildlife interface (unrestricted); non-porous livestock-wildlife interface (restricted by fencing); and livestock-wildlife non-interface (totally absent or control). Respondents randomly selected from a list of potential cattle farmers (N = 379) distributed at porous (40·1%), non-interface (35·5%) and non-porous (26·4%), were interviewed using a combined close- and open-ended questionnaire. Focus group discussions were conducted with 10-12 members of each community. More abortions in the last 5 years were reported from the porous interface (52%) and a significantly higher per cent of respondents from the porous interface (P < 0·05) perceived wildlife as playing a role in livestock abortions compared with the other interface types. The odds of reporting abortions in cattle were higher in large herd sizes (odds ratio (OR) = 2·6; 95% confidence interval (CI) 1·5-4·3), porous (OR = 1·9; 95% CI 1·0-3·5) and non-porous interface (OR = 2·2; 95% CI 1·1-4·3) compared with livestock-wildlife non-interface areas. About 21·6% of the respondents knew brucellosis as a cause of abortion, compared with RVF (9·8%) and leptospirosis (3·7%). These results explain to some extent, the existence of human/wildlife conflict in the studied livestock-wildlife interface areas of Zimbabwe, which militates against biodiversity conservation efforts. The low awareness of zoonoses means the public is at risk of contracting some of these infections. Thus, further studies should focus on livestock-wildlife interface areas to assess if the increased rates of abortions reported in cattle may be due to exposure to wildlife or other factors. The government of Zimbabwe needs to launch educational programmes on public health awareness in these remote areas at the periphery of transfrontier conservation areas where livestock-wildlife interface exists to help mitigate the morbidity and mortality of people from some of the known zoonotic diseases.

NASA conducted the latest successful test of the Orion spacecraft’s parachute system on March 8 in the skies above the U.S. Army’s Yuma Proving Ground in Arizona. The test was designed to evaluate the parachutes’ performance in an emergency abort situation that would require Orion to be jettisoned from the agency’s Space Launch System rocket during a launch. Even at this relatively low altitude, the parachutes are designed to fully deploy and safely return Orion and its crew to Earth.

Pressure and heat transfer tests were conducted simulating flight conditions which the space shuttle external tank will experience prior to break-up. The tests were conducted in the Calspan 48-inch Hypersonic Shock Tunnel and simulated entry conditions for nominal, abort-once-around (AOA), and return to launch site (RTLS) launch occurrences. Surface pressure and heat-transfer-rate distributions were obtained with and without various protuberences (or exterior hardware) on the model at Mach numbers from 15.2 to 17.7 at angles of attack from -15 deg to -180 deg and at several roll angles. The tests were conducted over a Reynolds number range from 1300 to 58,000, based on model length.

The emergency response dose assessment system (ERDAS) is a protype software and hardware system configured to produce routine mesoscale meteorological forecasts and enhanced dispersion estimates on an operational basis for the Kennedy Space Center (KSC)/Cape Canaveral Air Station (CCAS) region. ERDAS provides emergency response guidance to operations at KSC/CCAS in the case of an accidental hazardous material release or an aborted vehicle launch. This report describes the evaluation of ERDAS including: evaluation of sea breeze predictions, comparison of launch plume location and concentration predictions, case study of a toxic release, evaluation of model sensitivity to varying input parameters, evaluation of the user interface, assessment of ERDA's operational capabilities, and a comparison of ERDAS models to the ocean breeze dry gultch diffusion model.
