Quasars and the Caltech-Carnegie Connection  

NASA Astrophysics Data System (ADS)

A collaborative relationship existed between the California Institute of Technology (Caltech) and the Carnegie Institution of Washington (Carnegie) beginning in 1946, when a formal agreement was signed between the two groups of trustees. This agreement was designed to integrate Mount Wilson Observatory and the new unfinished Palomar Observatory into a single scientific entity. During the period from 1946 to 1979, much astronomical research was done at both institutions as a direct result of this collaboration. Part of this research included the first identification of a radio source with an apparently stellar object by Allan Sandage of Carnegie and Thomas Matthews of Caltech in 1960, and the first identification of spectral lines at large redshift from a radio source associated with such an object by Maarten Schmidt of Caltech in 1963. This paper examines how the discovery of these objects - which came to be known as quasars - and subsequent research an them, indirectly had an impact an the relationship between Caltech and Carnegie by leading to an environment of increased competitiveness that eventually resulted in the formal dissolution of the relationship in 1980. In this paper, the controversy surrounding the discovery and the interpretation of quasars is examined to provide further understanding about the working relationship when the two institutions were formally collaborating. Some of the data used in this paper were drawn from personal correspondence and interviews with the researchers themselves, and this research forms part of a dissertation for a Ph.D. degree in the Centre for Astronomy at James Cook University, Townsville, Australia.

Repurposing the Caltech Robinson Hall Coelostat  

NASA Astrophysics Data System (ADS)

We describe the repurposing of the historic coelostat atop Caltech’s Robinson Hall for building lighting, public education and scientific research. The coelostat was originally part of George Ellery Hale’s vision of the Astrophysical Laboratory on the Caltech campus in 1932. The coelostat, designed by Russell Porter, has a 36 inch diameter primary mirror a 30 inch diameter secondary mirror and provides a 24 inch un-vignetted beam of sunlight into the building. Although constructed in the 1930s, due to wartime pressures and other projects, it was used only briefly in the 1970s and never fully realized. Recently Robinson Hall has been fully renovated to house the Ronald and Maxine Linde Center for Global Environmental Science. The coelostat operation was modernized replacing the old motors and automating all the motions. Each morning, if the weather cooperates, the dome slit opens, the mirrors configured and sunlight pours into the building. The beam of sunlight is divided into three parts. One part goes into a refracting telescope which projects a ten inch diameter of the sun onto a ground glass screen visible to the public. A second fraction is distributed to fiber optic fixtures that illuminate some of the basement rooms. The final fraction goes into two laboratories where it is used in experiments monitoring trace constituents of our atmosphere and for solar catalysis experiments. The instrument as originally conceived required at least two human operators. Now it is fully automatic and doing real science

dc readout experiment at the Caltech 40m prototype interferometer  

NASA Astrophysics Data System (ADS)

The Laser Interferometer Gravitational Wave Observatory (LIGO) operates a 40m prototype interferometer on the Caltech campus. The primary mission of the prototype is to serve as an experimental testbed for upgrades to the LIGO interferometers and for gaining experience with advanced interferometric techniques, including detuned resonant sideband extraction (i.e. signal recycling) and dc readout (optical homodyne detection). The former technique will be employed in Advanced LIGO, and the latter in both Enhanced and Advanced LIGO. Using dc readout for gravitational wave signal extraction has several technical advantages, including reduced laser and oscillator noise couplings as well as reduced shot noise, when compared to the traditional rf readout technique (optical heterodyne detection) currently in use in large-scale ground-based interferometric gravitational wave detectors. The Caltech 40m laboratory is currently prototyping a dc readout system for a fully suspended interferometric gravitational wave detector. The system includes an optical filter cavity at the interferometer's output port, and the associated controls and optics to ensure that the filter cavity is optimally coupled to the interferometer. We present the results of measurements to characterize noise couplings in rf and dc readout using this system.

NASA Astrophysics Data System (ADS)

CASIMIR, the Caltech Airborne Submillimeter Interstellar Medium Investigations Receiver is a multiband, far infrared and submillimeter, high resolution, heterodyne spectrometer under development for SOFIA. It is a first generation, PI class instrument. CASIMIR is designed for detailed, high sensitivity observations of warm (100 K) interstellar gas both in external galaxies and Galactic sources, including molecular clouds, circumstellar envelopes, and protostellar cores. Combining the 2.5 m SOFIA mirror with state of the art superconducting mixers, will give CASIMIR unprecedented sensitivity. Initially, CASIMIR will have two bands, at 1000 and 1250 GHz, and a further three bands, 550, 750, 1400 GHz, will be added soon after. Any four bands will be available on each flight. The availability of multiple bands during each flight will allow for efficient use of flight time. For example, searches for weak lines from rare species in bright sources can be carried out on the same flight with observations of abundant species in faint or distant objects.

Observing Energetic Bursts in the Caltech Solar Coronal Loop Simulation  

NASA Astrophysics Data System (ADS)

X-ray bursts have previously been observed in a solar coronal loop experiment (J.F. Hansen, S.K.P. Tripathi, and P.M. Bellan, Phys. Plasma 2, 3177(2004)) where two parallel plasma-filled flux tubes merged in either a co-helicity or counter-helicity arrangement. These x-ray bursts were observed with a set of x-ray photo-diodes. We are developing means to observe these bursts with additional diagnostics. A low cost photo-electric detector was thoroughly tested on a test chamber using a xenon flashlamp. The detector utilizes the low work function of magnesium to measure ultraviolet radiation. A photo-scintillator is being developed to detect hard x-ray emission down to 10 keV. A smaller photo-scintillator was previously constructed and used in the Caltech spheromak experiment; we have enlarged the scintillating volume in hopes of increasing sensitivity. Finally, in a single loop experiment, spectroscopic measurements detect the onset of oxygen impurity lines at the loop apex; the onset is simultaneous with the formation of a bright spot at the same location. Future spectroscopic measurements are planned to investigate the apex region during merging.

In the past year we have mapped the polarization of thermal emission at 350 \\micron\\ of 12 galactic molecular clouds with the University of Chicago's array polarimeter Hertz (Schleuning et al 1997, Dowell et al 1997) at the Caltech Submillimeter Observatory. Polarimetry of thermal emission is proving to be a powerful method to investigate magnetic fields (eg Schleuning 1997, Dotson 1996) and dust properties (eg Hildebrand & Dragovan 1995) in molecular clouds. Here we will present polarization maps of the observed sources which include 3 galactic center clouds (the dust ring, M-0.13-0.08, M-0.02-0.07) and several high mass star formation regions (SgrB2, M17, DR21 and NGC 2024). In the elongated clouds DR21 and NGC 2024, the magnetic field is perpendicular to the cloud along its length. In the DR21 Main region, we resolve an apparent hourglass field geometry. We will also briefly discuss global trends observed in the data set.

Modernization of the Caltech/USGS Southern California Seismic Network  

NASA Astrophysics Data System (ADS)

The USGS/ANSS/ARRA program is providing Government Furnished Equipment (GFE), and two year funding for upgrading the Caltech/USGS Southern California Seismic Network (SCSN). The SCSN is the modern digital ground motion seismic network in southern California that monitors seismicity and provides real-time earthquake information products such as rapid notifications, moment tensors, and ShakeMap. The SCSN has evolved through the years and now consists of several well-integrated components such as Short-Period analog, TERRAscope, digital stations, and real-time strong motion stations, or about 300 stations. In addition, the SCSN records data from about 100 stations provided by partner networks. To strengthen the ability of SCSN to meet the ANSS performance standards, we will install GFE and carry out the following upgrades and improvements of the various components of the SCSN: 1) Upgrade of dataloggers at seven TERRAscope stations; 2) Upgrade of dataloggers at 131 digital stations and upgrade broadband sensors at 25 stations; 3) Upgrade of SCSN metadata capabilities; 4) Upgrade of telemetry capabilities for both seismic and GPS data; and 5) Upgrade balers at stations with existing Q330 dataloggers. These upgrades will enable the SCSN to meet the ANSS Performance Standards more consistently than before. The new equipment will improve station uptimes and reduce maintenance costs. The new equipment will also provide improved waveform data quality and consequently superior data products. The data gaps due to various outages will be minimized, and ‘late’ data will be readily available through retrieval from on-site storage. Compared to the outdated equipment, the new equipment will speed up data delivery by about 10 sec, which is fast enough for earthquake early warning applications. The new equipment also has about a factor of ten lower consumption of power. We will also upgrade the SCSN data acquisition and data center facilities, which will improve the SCSN performance and metadata availability. We will improve existing software to facilitate the update of metadata, and to improve the interoperability between SeisNetWatch and our database of metadata. The improved software will also be made available to other regional networks as part of the CISN software distribution. These upgrades, will greatly improve the robustness of the SCSN, and facilitate higher quality and more reliable earthquake monitoring than was available before in southern California. The modernized SCSN will contribute to more coordinated search and rescue as well as economic resilience following a major earthquake by providing accurate earthquake information, and thus facilitate rapid deployment of field crews and rapid business resumption. Further, advances in seismological research will be facilitated by the high quality seismic data that will be collected in one of the most seismically active areas in the contiguous US.

Aerospace Robotics Laboratory  

NSDL National Science Digital Library

The Aerospace Robotics Laboratory (ARL), operated at Stanford University, focuses its research "on improving robotic performance through the application of feedback control, integrated sensing systems, and task-level autonomy." The systems designed at ARL allow the human operator to have varying levels of control over the robot. Specifically, the robot performs given tasks until it reaches a point that it can not perform on its own. The human can then intervene and direct the robot manually. A comprehensive list of all ARL publications is available on the Web site, ranging from the 1960's to 2002 (many of the publications after 1990 are available for download). There are even movies of laboratory experiments and demonstrations that can be downloaded and viewed. The Projects section explains the various research projects currently underway.

Aerospace and military  

SciTech Connect

This article reviews military and aerospace developments of 1989. The Voyager spacecraft returned astounding imagery from Neptune, sophisticated sensors were launched to explore Venus and Jupiter, and another craft went into earth orbit to explore cosmic rays, while a huge telescope is to be launched early in 1990. The U.S. space shuttle redesign was completed and access to space has become no longer purely a governmental enterprise. In the military realm, events within the Soviet bloc, such as the Berlin Wall's destruction, have popularized arms control. Several big treaties could be signed within the year. Massive troop, equipment, and budget reductions are being considered, along with a halt or delay of major new weapons systems. For new missions, the U.S. military is retreating to its role of a century ago - patrolling the nation's borders, this time against narcotics traffickers.

Aerospace Safety Advisory Panel  

NASA Astrophysics Data System (ADS)

This report provides findings, conclusions and recommendations regarding the National Space Transportation System (NSTS), the Space Station Freedom Program (SSFP), aeronautical projects and other areas of NASA activities. The main focus of the Aerospace Safety Advisory Panel (ASAP) during 1988 has been monitoring and advising NASA and its contractors on the Space Transportation System (STS) recovery program. NASA efforts have restored the flight program with a much better management organization, safety and quality assurance organizations, and management communication system. The NASA National Space Transportation System (NSTS) organization in conjunction with its prime contractors should be encouraged to continue development and incorporation of appropriate design and operational improvements which will further reduce risk. The data from each Shuttle flight should be used to determine if affordable design and/or operational improvements could further increase safety. The review of Critical Items (CILs), Failure Mode Effects and Analyses (FMEAs) and Hazard Analyses (HAs) after the Challenger accident has given the program a massive data base with which to establish a formal program with prioritized changes.

Retention of Women in Geoscience Undergraduate and Graduate Education at Caltech  

NASA Astrophysics Data System (ADS)

Institutional barriers encountered by women in undergraduate and graduate schools may take many forms, but can also be as simple as a lack of community support. In the 1990's the California Institute of Technology (Caltech) made a commitment to the retention of women in their graduate and undergraduate schools. Their program included mentoring, focussed tutoring, self-esteem support groups, and other retention efforts. Under this program, the attrition rate of women has dramatically slowed. In this paper, we will discuss recent data from the American Geological Institude chronicling the enrollment and successes of women in the geosciences, the program instituted by Caltech, possible causes of attrition among women in the geosciences, as well as potential programs to address these problems. We will also present, from the nationwide study, data on geoscience departments which have been relatively successful at retaining and graduating women in Earth and Space Sciences.

Aluminum-lithium for aerospace  

SciTech Connect

Aluminum-lithium alloys were developed primarily to reduce the weight of aircraft and aerospace structures. Lithium is the lightest metallic element, and each 1% of lithium added to aluminum reduces alloy density by about 3% and increases modulus by about 5%. Though lithium has a solubility limit of 4.2% in aluminum, the amount of lithium ranges between 1 and 3% in commercial alloys. Aluminum-lithium alloys are most often selected for aerospace components because of their low density, high strength, and high specific modulus. However, other applications now exploit their excellent fatigue resistance and cryogenic toughness.

Developing an Education and Public Outreach (EPO) program for the Caltech Tectonics Observatory  

NASA Astrophysics Data System (ADS)

The Caltech Tectonics Observatory (TO) is an interdisciplinary center, focused on geological processes occurring at the boundaries of Earth's tectonic plates. The timescales of these processes span from a few tens of seconds (the typical duration of an earthquake) to tens of millions of years (the time it takes to build mountains). Over the past four years, the TO has brought together 15 Caltech faculty from different fields, several visiting scientists from around the globe, and a few tens of graduate students and postdoctoral students, collaborating on scientific projects. A major objective of the TO now is to develop an Education and Public Outreach (EPO) program. Our goals are to (1) stimulate the interest of students and the general public in Earth Sciences, particularly in the study of tectonic processes, (2) inform and educate the general public about TO discoveries and advancements, and (3) make available the data and techniques developed by the TO for use in classrooms of all levels. To this effect, we have been developing our website for accessibility by the general public and writing educational web articles on TO research. A recent well-visited example is "The science behind the recent 2008 earthquake in China." We distribute animations that illustrate the mechanisms of earthquakes and tsunamis, and the various techniques used by TO scientists in their scientific investigations. The TO website also provides access to geodetic data collected by TO instruments and to the source models of recent large earthquakes as analyzed by TO scientists. The TO hosts tours of its facilities for local elementary school students and is working on developing education modules for high school and undergraduate classes. We are now working on a plan to offer short courses over the summer for undergraduate and graduate students in other institutions, in order to train them to analyze a variety of data and use techniques developed by TO scientists.

Spectral Line Surveys of Young Stellar Objects Using the Caltech Submillimeter Observatory  

NASA Astrophysics Data System (ADS)

Advancements in radioastronomical instrumentation have allowed for the identification of approximately 170 interstellar molecules, many of which are complex organic molecules (COMs). Many of the detected COMs, including species such as glycolaldehyde and formamide, are thought to be prebiotic precursors in the chemistry of these star-forming regions. Complex organic chemistry is especially rich in hot cores/corinos, where thermal evaporation during the warm-up phase of star-formation releases molecules from icy grain mantles into the gas phase. Grain surface and gas phase astrochemical models provide predicted abundances of COMs, and these predictions can be tested through observations of a variety of sources. We have used the Caltech Submillimeter Observatory (CSO) to conduct deep ?=1.3mm unbiased line surveys of 8 sources including hot cores, hot corinos, dense molecular clouds, and shocked regions. These line surveys cover frequencies in the range of 215 - 270 GHz with an RMS noise level of ˜30 mK, which is sufficiently deep to probe many of the largest COMs that have been identified to date. We have performed detailed spectral analyses for these line surveys targeting a range of COMs that test the chemical mechanisms included in astrochemical models. Here we present the spectra and results of a quantitative analysis of these sources, and discuss the implications of these results for astrochemical models.

Optics for MUSIC: a new (sub)millimeter camera for the Caltech Submillimeter Observatory  

NASA Astrophysics Data System (ADS)

We will present the design and implementation, along with calculations and some measurements of the performance, of the room-temperature and cryogenic optics for MUSIC, a new (sub)millimeter camera we are developing for the Caltech Submm Observatory (CSO). The design consists of two focusing elements in addition to the CSO primary and secondary mirrors: a warm off-axis elliptical mirror and a cryogenic (4K) lens. These optics will provide a 14 arcmin field of view that is diffraction limited in all four of the MUSIC observing bands (2.00, 1.33, 1.02, and 0.86 mm). A cold (4K) Lyot stop will be used to define the primary mirror illumination, which will be maximized while keeping spillover at the sub 1% level. The MUSIC focal plane will be populated with broadband phased antenna arrays that efficiently couple to factor of (see manuscript) 3 in bandwidth,1, 2 and each pixel on the focal plane will be read out via a set of four lumped element filters that define the MUSIC observing bands (i.e., each pixel on the focal plane simultaneously observes in all four bands). Finally, a series of dielectric and metal-mesh low pass filters have been implemented to reduce the optical power load on the MUSIC cryogenic stages to a quasi-negligible level while maintaining good transmission in-band.

Smart materials and aerospace structures  

NASA Astrophysics Data System (ADS)

Starting from the very definition of smart structures and smart materials, this paper addresses the fundamental mechanism of operation of some well known smart materials like piezoelectric ceramic/polymer, electrostrictive ceramic, magnetostrictive alloy, shape memory alloy, electroheological fluid, magnetoheological fluid, optical fibers and so on. It also describes briefly the working principles of the actuators and sensor based upon these materials. In addition to that an overview of the various applications and research dealing with the application of these smart materials in aerospace structures mainly in the context of vibration suppression, shape control and adaptive structures for their efficient functioning has been presented. On the whole the presentation stresses on actuators. Since it is the actuator not the sensor that is often the limiting factor in smart structure used for active control. Numerous investigations have been made and are on the way to improve upon the piezoelectric and electrostrictive actuator for greater generating force and larger stroke, as well as shape memory alloy actuator for fast response. Development of multilayer piezoelectric and electrostrictive actuator and discovery of precompressed piezoelectric element and actuator is a forward leap in that direction.

Modernization of the Caltech/USGS Southern California Seismic Network - ARRA and Beyond  

NASA Astrophysics Data System (ADS)

The USGS/ANSS/ARRA program provided equipment and funding to upgrade the equipment and infrastructure of the Caltech/USGS Southern California Seismic Network (SCSN). The SCSN is a modern digital seismic network that provides real-time earthquake information products such as rapid notifications, moment tensors, and ShakeMap. ARRA funds were used to modernize 178 of 300 SCSN stations, upgrade telemetry hubs, and build a state-of-the-art microwave telemetry backbone. With these upgrades complete, we are taking the next step of upgrading the analog short-period stations to digital short-period stations and adding strong motion sensors to them. We also are installing NetQuakes strong motion instruments to fill gaps in our urban recording capability. The ARRA-funded upgrades allow the SCSN to meet the ANSS Performance Standards more consistently than before. The new equipment makes the SCSN stations more homogeneous, significantly boosts station uptimes, reduces maintenance costs, and improves waveform data quality. The new data-loggers send data with reduced delays, which is critical for earthquake early warning applications. Station data quality was checked before each upgrade allowing sensor and site problems to be found, so that they could be addressed and data quality could be improved during the upgrade site visit. Data quality checks also were performed during the upgrade work and station metadata was changed in real time as work progressed. Sensor orientations were checked at over 115 sites using an OCTANS gyro-compass and mis-orientations were documented and corrected. To further take advantage of the ARRA-supplied equipment, we have developed scripts to take advantage of features from the new Q330 data-loggers: automatic detection of out-of-range mass positions with automatic recentering, and automatic data requests to fill data gaps. We also expanded the features and extended the utility of our Station Information System (SIS).

Modernization of the Caltech/USGS Southern California Seismic Network - Progress Report  

NASA Astrophysics Data System (ADS)

The USGS/ANSS/ARRA program has provided Government Furnished Equipment (GFE) and funding to upgrade the Caltech/USGS Southern California Seismic Network (SCSN). The SCSN is a modern digital ground motion seismic network in southern California. The SCSN monitors seismicity and provides real-time earthquake information products such as rapid notifications, moment tensors, and ShakeMap. Of the roughly 300 stations in the SCSN, 178 digital stations are the focus for the ARRA-funded upgrade. We have completed over half of these upgrades, and will complete the remainder by the end of September 2011. The ARRA-funded upgrades are enabling the SCSN to meet the ANSS Performance Standards more consistently than before, and also are presenting many unique opportunities for the network. The new equipment gives the network a higher level of standardization across 178 digital stations - more than half the network. This is improving station uptimes and reducing maintenance costs. The new equipment also provides improved waveform data quality and consequently superior data products. Data gaps due to various outages can now be minimized and “late” data has become readily available from increased on-site storage. Compared to the outdated equipment, the new dataloggers are producing data with reduced delays, increasing the efficacy of future earthquake early warning applications. The new dataloggers also decrease station power consumption by roughly a factor of ten. The ARRA upgrades are allowing us to do preventative maintenance that is increasing each station's robustness and longevity. In addition, we are upgrading all of our strong motion sensors at digital sites to 4g Episensors, increasing the network's ability to resolve strong ground motions - a significant consideration in southern California. Station data quality is checked in anticipation of each upgrade so that instrumentation problems can be addressed and data quality improved during the upgrade site visit. Data quality checks performed during the upgrade work allow the station metadata to be changed in real time to reflect the installation of new equipment. In conjunction with the ARRA upgrade, we have begun a campaign to verify the orientation of all the sensors at each SCSN site. Using an Octans gyrocompass, we have completed orientation verifications at 50 of the SCSN broadband sites. Mis-orientations are now being documented in the metadata for affected stations, and sensors with the largest mis-orientations are being reinstalled with true north orientation. Once completed, the combined upgrades and orientation verifications will have greatly improved the robustness of the SCSN, facilitating higher quality and more reliable earthquake monitoring than was previously available in southern California.

Recent advances in aerospace composite NDE  

NASA Astrophysics Data System (ADS)

As the aerospace industry continues to advance the design and use of composite structure, the NDE community faces the difficulties of trying to keep up. The challenges lie in manufacturing evaluation of the newest aerospace structures and materials and the in-service inspection and monitoring of damaged or aging composites. This paper provides examples of several promising NDI applications in the world of aerospace composites. Airborne (or non-contact) Ultrasonic Testing (UT) has been available for decades, but recently has generated new interest due to significant improvements in transducer design and low noise electronics. Boeing is developing inspection techniques for composite joints and core blankets using this technology. In-service inspection techniques for thick, multi-layer structures are also being advanced. One effective technique integrates the S-9 Sondicator, a traditional bond testing device, with Boeing's Mobile Automated Scanner (MAUS) platform. Composite patches have seen limited use on-aircraft, due, in part, to the difficulty of determining the quality of a bonded joint. A unique approach using Electronic Speckle Pattern Interferometry (ESPI) is showing promise as a bonded patch-inspection method. Other NDI techniques currently being developed for aerospace application are also briefly discussed.

The cryomechanical design of MUSIC: a novel imaging instrument for millimeter-wave astrophysics at the Caltech Submillimeter Observatory  

NASA Astrophysics Data System (ADS)

MUSIC (Multicolor Submillimeter kinetic Inductance Camera) is a new facility instrument for the Caltech Submillimeter Observatory (Mauna Kea, Hawaii) developed as a collaborative effect of Caltech, JPL, the University of Colorado at Boulder and UC Santa Barbara, and is due for initial commissioning in early 2011. MUSIC utilizes a new class of superconducting photon detectors known as microwave kinetic inductance detectors (MKIDs), an emergent technology that offers considerable advantages over current types of detectors for submillimeter and millimeter direct detection. MUSIC will operate a focal plane of 576 spatial pixels, where each pixel is a slot line antenna coupled to multiple detectors through on-chip, lumped-element filters, allowing simultaneously imaging in four bands at 0.86, 1.02, 1.33 and 2.00 mm. The MUSIC instrument is designed for closed-cycle operation, combining a pulse tube cooler with a two-stage Helium-3 adsorption refrigerator, providing a focal plane temperature of 0.25 K with intermediate temperature stages at approximately 50, 4 and 0.4 K for buffering heat loads and heat sinking of optical filters. Detector readout is achieved using semi-rigid coaxial cables from room temperature to the focal plane, with cryogenic HEMT amplifiers operating at 4 K. Several hundred detectors may be multiplexed in frequency space through one signal line and amplifier. This paper discusses the design of the instrument cryogenic hardware, including a number of features unique to the implementation of superconducting detectors. Predicted performance data for the instrument system will also be presented and discussed.

The All Weather ARrival and Departure (AWARD) program is supported by the European Commission under the Brite-EuRam III structure. Following the VERSATILE preparation program, it started on June 1996 and is planned to finish end of 1999. The program consortium consists of ten partners such as a major airline, aircraft and equipment manufacturers, research and tests centers, and an university. Contractors from France, Germany, Great Britain, Italy and The Netherlands are coordinated by Sextant Avionique. AWARD main objective is to demonstrate the efficiency of vision systems under adverse weather conditions. In order to evaluate the added benefits of these concepts within aircraft operations of approach, landing, taxi and takeoff, two applications are developed: (1) Enhanced Vision System (EVS) based on Head Up Display enhancement with Forward Looking Infrared (FLIR) and Millimeter Wave Radar (MMWR) images. (2) Synthetic Vision System (SVS) displaying an overlaid symbology on a perspective presentation of the environment, thanks to the combination of database and accurate positioning systems. The evaluation of these two tests systems will focus on: (1) Performance and human acceptability aspects. They will be appreciated according to human factors criteria as well as an integration within realistic environments. The NLR Research Flight Simulator and the DLR ATTAS flight test aircraft will be used. (2) Reliability, integrity aspects thanks to a theoretical certification/system study which will propose guidelines for certification, and will address impact on the system architecture. The paper addresses the work structure of AWARD in order to show what are the keypoints addressed in this program.

Advanced electromagnetic methods for aerospace vehicles  

NASA Astrophysics Data System (ADS)

High- and low-frequency methods to analyze various radiation elements located on aerospace vehicles with combinations of conducting, nonconducting, and energy absorbing surfaces and interfaces. The focus was on developing fundamental concepts, techniques, and algorithms which would remove some of the present limitations in predicting radiation characteristics of antennas on complex aerospace vehicles. In order to accomplish this, the following subjects were examined: (1) the development of techniques for rigorous analysis of surface discontinuities of metallic and nonmetallic surfaces using the equivalent surface impedance concept and Green's function; (2) the effects of anisotropic material on antenna radiation patterns through the use of an equivalent surface impedance concept which is incorporated into the existing numerical electromagnetics computer codes; and (3) the fundamental concepts of precipitation static (P-Static), such as formulations and analytical models. A computer code was used to model the P-Static process on a simple structure. Measurement techniques were also developed to characterized the electrical properties at microwave frequencies. Samples of typical materials used in airframes were tested and the results are included.

The conceptual design of a military transatmospheric aerospace plane candidate involves the selection of the mission(s), operating environment, operational concept, payload definition, specific design choices, and a close look at the technology base. A broad range of missions and concepts were reviewed prior to the selection of the mission and concepts presented in this paper. The mission selected was CONUS based global strike. The flight profile selected was a boost-glide-skip unrefuled global range trajectory. Two concepts were selected. The first was a rocket-powered design and the second was a combined air-breathing and rocket powered design. The rocket-powered configuration is a high lift-to-drag ratio modified lifting body. The rocket engine is an advanced dual fuel linear aero-spike. The air-breathing powered configuration is a modified waverider configuration. The engine for the air-breather is a rocket based combined cycle engine. Performance and technology readiness comparisons are presented for the two concepts. The paper closes with a discussion of lessons learned about military transatmospheric aerospace planes over the past twenty years. {copyright} {ital 1997 American Institute of Physics.}

CALTECH CORE-COLLAPSE PROJECT (CCCP) OBSERVATIONS OF TYPE IIn SUPERNOVAE: TYPICAL PROPERTIES AND IMPLICATIONS FOR THEIR PROGENITOR STARS  

SciTech Connect

Type IIn supernovae (SNe IIn) are rare events, constituting only a few percent of all core-collapse SNe, and the current sample of well-observed SNe IIn is small. Here, we study the four SNe IIn observed by the Caltech Core-Collapse Project (CCCP). The CCCP SN sample is unbiased to the extent that object selection was not influenced by target SN properties. Therefore, these events are representative of the observed population of SNe IIn. We find that a narrow P-Cygni profile in the hydrogen Balmer lines appears to be a ubiquitous feature of SNe IIn. Our light curves show a relatively long rise time (>20 days) followed by a slow decline stage (0.01-0.15 mag day{sup -1}), and a typical V-band peak magnitude of M{sub V} = -18.4 {+-} 1.0 mag. We measure the progenitor star wind velocities (600-1400 km s{sup -1}) for the SNe in our sample and derive pre-explosion mass-loss rates (0.026-0.12 M{sub Sun} yr{sup -1}). We compile similar data for SNe IIn from the literature and discuss our results in the context of this larger sample. Our results indicate that typical SNe IIn arise from progenitor stars that undergo luminous-blue-variable-like mass loss shortly before they explode.

30 GHz flux density measurements of the Caltech-Jodrell flat-spectrum sources with OCRA-p  

NASA Astrophysics Data System (ADS)

Aims:To measure the 30-GHz flux densities of the 293 sources in the Caltech-Jodrell Bank flat-spectrum (CJF) sample. The measurements are part of an ongoing programme to measure the spectral energy distributions of flat spectrum radio sources and to correlate them with the milliarcsecond structures from VLBI and other measured astrophysical properties. Methods: The 30-GHz data were obtained with a twin-beam differencing radiometer system mounted on the Toru? 32-m telescope. The system has an angular resolution of 1.2´. Results: Together with radio spectral data obtained from the literature, the 30-GHz data have enabled us to identify 42 of the CJF sources as Giga-hertz Peaked Spectrum (GPS) sources. Seventeen percent of the sources have rising spectra (? > 0) between 5 and 30 GHz.

CALTECH CORE-COLLAPSE PROJECT (CCCP) OBSERVATIONS OF TYPE II SUPERNOVAE: EVIDENCE FOR THREE DISTINCT PHOTOMETRIC SUBTYPES  

SciTech Connect

We present R-band light curves of Type II supernovae (SNe) from the Caltech Core-Collapse Project (CCCP). With the exception of interacting (Type IIn) SNe and rare events with long rise times, we find that most light curve shapes belong to one of three apparently distinct classes: plateau, slowly declining, and rapidly declining events. The last class is composed solely of Type IIb SNe which present similar light curve shapes to those of SNe Ib, suggesting, perhaps, similar progenitor channels. We do not find any intermediate light curves, implying that these subclasses are unlikely to reflect variance of continuous parameters, but rather might result from physically distinct progenitor systems, strengthening the suggestion of a binary origin for at least some stripped SNe. We find a large plateau luminosity range for SNe IIP, while the plateau lengths seem rather uniform at approximately 100 days.

Design search and optimization in aerospace engineering.  

PubMed

In this paper, we take a design-led perspective on the use of computational tools in the aerospace sector. We briefly review the current state-of-the-art in design search and optimization (DSO) as applied to problems from aerospace engineering, focusing on those problems that make heavy use of computational fluid dynamics (CFD). This ranges over issues of representation, optimization problem formulation and computational modelling. We then follow this with a multi-objective, multi-disciplinary example of DSO applied to civil aircraft wing design, an area where this kind of approach is becoming essential for companies to maintain their competitive edge. Our example considers the structure and weight of a transonic civil transport wing, its aerodynamic performance at cruise speed and its manufacturing costs. The goals are low drag and cost while holding weight and structural performance at acceptable levels. The constraints and performance metrics are modelled by a linked series of analysis codes, the most expensive of which is a CFD analysis of the aerodynamics using an Euler code with coupled boundary layer model. Structural strength and weight are assessed using semi-empirical schemes based on typical airframe company practice. Costing is carried out using a newly developed generative approach based on a hierarchical decomposition of the key structural elements of a typical machined and bolted wing-box assembly. To carry out the DSO process in the face of multiple competing goals, a recently developed multi-objective probability of improvement formulation is invoked along with stochastic process response surface models (Krigs). This approach both mitigates the significant run times involved in CFD computation and also provides an elegant way of balancing competing goals while still allowing the deployment of the whole range of single objective optimizers commonly available to design teams.

Outstanding student paper awards  

NASA Astrophysics Data System (ADS)

The Ocean Sciences Section presented the following outstanding student paper awards at the 1998 AGU-ASLO Ocean Sciences Meeting in San Diego, California, last February. Juli M. Berwald presented a poster titled “The Packet Model for the Downwelling Average Cosine of Irradiance in the Ocean,” coauthored by C. D. Mobley and D. A. Kiefer. Juli received her B.A. in mathematics from Amherst College in 1989. Her doctoral research at the University of Southern California focused on understanding relationships between the inherent and apparent optical properties in the ocean. Most of her work is based on results from radiative transfer calculations which mathematically describe how water and particles affect the magnitude and direction of radiance in the ocean. The Lamina Model of the Downwelling Average Cosine of Irradiance, which formed the basis of her AGU presentation, will be incorporated into a new model for reflectance in the ocean. Juli has also developed models of the average cosine of irradiance in which the effects of scattering and absorption on the shape of the underwater light field are individually identified. In addition, she has investigated the effects of raman scattering on the average cosine and the diffuse attenuation coefficient throughout the water column and into the asymptotic field. Juli's graduate work has been supported by a NASA fellowship in Global Change.

Electrical machines technology for aerospace power generators  

NASA Astrophysics Data System (ADS)

Electric power generators for aerospace and aircraft applications are now required to be more reliable. It is noted that the wound field synchronous generator has been the workhorse for producing 400-Hz AC electric power for many years. Substantial evolution has occurred over the years by replacing low-speed generators with the 24,000-rpm design. The quality of the AC waveform produced by the wound field generators is excellent, the excitation power requirement is low, and control of output power is easily accomplished under abnormal operating conditions. Other changing requirements include variety of power types, increased reliability, and higher speeds and temperatures. It is pointed out that wound field synchronous generators have limitations due to rotating windings and rotating rectifiers. Other options such as self-regulating permanent magnet generators, switched reluctance generators, reluctance generators, flux switches overcome these limitations. It is suggested that the selection from these options must be based on the specific requirements for a given application, evaluating overall system constraints such as weight, performance, and cost.

Lightweight acoustic treatments for aerospace applications  

NASA Astrophysics Data System (ADS)

Increase in the use of composites for aerospace applications has the benefit of decreased structural weight, but at the cost of decreased acoustic performance. Stiff, lightweight structures (such as composites) are traditionally not ideal for acoustic insulation applications because of high transmission loss at low frequencies. A need has thus arisen for effective sound insulation materials for aerospace and automotive applications with low weight addition. Current approaches, such as the addition of mass law dominated materials (foams) also perform poorly when scaled to small thickness and low density. In this dissertation, methods which reduce sound transmission without adding significant weight are investigated. The methods presented are intended to be integrated into currently used lightweight structures such as honeycomb sandwich panels and to cover a wide range of frequencies. Layering gasses of differing acoustic impedances on a panel substantially reduced the amount of sound energy transmitted through the panel with respect to the panel alone or an equivalent-thickness single species gas layer. The additional transmission loss derives from successive impedance mismatches at the interfaces between gas layers and the resulting inefficient energy transfer. Attachment of additional gas layers increased the transmission loss (TL) by as much as 17 dB at high (>1 kHz) frequencies. The location and ordering of the gasses with respect to the panel were important factors in determining the magnitude of the total TL. Theoretical analysis using a transfer matrix method was used to calculate the frequency dependence of sound transmission for the different configurations tested. The method accurately predicted the relative increases in TL observed with the addition of different gas layer configurations. To address low-frequency sound insulation, membrane-type locally resonant acoustic materials (LRAM) were fabricated, characterized, and analyzed to understand their acoustic response. Acoustic metamaterials with negative dynamic mass density have been shown to demonstrate a significant (5x) increase in TL over mass law predictions for a narrow band (100Hz) at low frequencies (100--1000Hz). The peak TL frequency can be tuned to specific values by varying the membrane and mass properties. TL magnitude as a function of frequency was measured for variations of the mass magnitude and membrane tension using an impedance tube setup. The dynamic properties of membranes constructed from different materials and thicknesses were measured and compared to the results of coupled field acoustic-structural finite element analysis (FEA) modeling to understand the role of tension and element quality factor. To better comprehend the mechanism(s) responsible for the TL peak, a laser vibrometer was used to map the out-of-plane dynamic response of the structure under acoustic loading at discrete frequencies. Negative dynamic mass was experimentally demonstrated at the peak TL frequency. The scale-up of the acoustic metamaterial structure was explored by examining the behavior of multiple elements arranged in arrays. Single membranes were stretched over rigid frame supports and masses were attached to the center of each divided cell. TL behavior was measured for multiple configurations with different magnitudes of mass distributed across each of the cell membranes in the array resulting in a multi-peak TL profile. To better understand scale-up issues, the effect of the frame structure compliance was evaluated, and more compliant frames resulted in a reduction in TL peak frequency bandwidth. In addition, displacement measurements of frames and membranes were performed using a laser vibrometer. The measured TL of the multi-celled structure was compared with TL behavior predicted by FEA to understand the role of non-uniform mass distribution and frame compliance. TL of membrane-type LRAM with added ring masses was analyzed using both finite element analysis and experimental techniques. The addition of a ring mass to the structure either increased th

Stanford Aerospace Research Laboratory research overview  

NASA Astrophysics Data System (ADS)

Over the last ten years, the Stanford Aerospace Robotics Laboratory (ARL) has developed a hardware facility in which a number of space robotics issues have been, and continue to be, addressed. This paper reviews two of the current ARL research areas: navigation and control of free flying space robots, and modelling and control of extremely flexible space structures. The ARL has designed and built several semi-autonomous free-flying robots that perform numerous tasks in a zero-gravity, drag-free, two-dimensional environment. It is envisioned that future generations of these robots will be part of a human-robot team, in which the robots will operate under the task-level commands of astronauts. To make this possible, the ARL has developed a graphical user interface (GUI) with an intuitive object-level motion-direction capability. Using this interface, the ARL has demonstrated autonomous navigation, intercept and capture of moving and spinning objects, object transport, multiple-robot cooperative manipulation, and simple assemblies from both free-flying and fixed bases. The ARL has also built a number of experimental test beds on which the modelling and control of flexible manipulators has been studied. Early ARL experiments in this arena demonstrated for the first time the capability to control the end-point position of both single-link and multi-link flexible manipulators using end-point sensing. Building on these accomplishments, the ARL has been able to control payloads with unknown dynamics at the end of a flexible manipulator, and to achieve high-performance control of a multi-link flexible manipulator.

Actively controlled shaft seals for aerospace applications  

NASA Astrophysics Data System (ADS)

This study experimentally investigates an actively controlled mechanical seal for aerospace applications. The seal of interest is a gas seal, which is considerably more compact than previous actively controlled mechanical seals that were developed for industrial use. In a mechanical seal, the radial convergence of the seal interface has a primary effect on the film thickness. Active control of the film thickness is established by controlling the radial convergence of the seal interface with piezoelectric actuator. An actively controlled mechanical seal was initially designed and evaluated using a mathematical model. Based on these results, a seal was fabricated and tested under laboratory conditions. The seal was tested with both helium and air, at rotational speeds up to 3770 rad/sec, and at sealed pressures as high as 1.48 x 10(exp 6) Pa. The seal was operated with both manual control and with a closed-loop control system that used either the leakage rate or face temperature as the feedback. The output of the controller was the voltage applied to the piezoelectric actuator. The seal operated successfully for both short term tests (less than one hour) and for longer term tests (four hours) with a closed-loop control system. The leakage rates were typically 5-15 slm (standard liters per minute), and the face temperatures were generally maintained below 100 C. When leakage rate was used as the feedback signal, the setpoint leakage rate was typically maintained within 1 slm. However, larger deviations occurred during sudden changes in sealed pressure. When face temperature was used as the feedback signal, the setpoint face temperature was generally maintained within 3 C, with larger deviations occurring when the sealed pressure changed suddenly.

Factors Influencing Advancement of Women Senior Leaders in Aerospace Companies  

NASA Astrophysics Data System (ADS)

The problem researched in this study was the limited number of women in senior leadership positions in the aerospace industry. The purpose of this qualitative phenomenological research study was to interview women senior leaders in the aerospace industry to explore the factors they perceived as beneficial to their advancement to senior leadership positions in the aerospace industry. The research study was guided by a central research question relating to what professional and personal factors might have led to promotional opportunities into senior leadership roles. Transformational leadership was the conceptual framework used to inform the study. The qualitative, phenomenological approach was selected to gain insights of the lived experiences and perceptions relating to career advancement of women to senior leadership positions in the aerospace industry. Data were collected using a modified Van Kaam method, coded, and analyzed to discern themes or patterns. Findings were that the attributes participants contributed to their success, included a focus on leadership, personal development, and the importance of mentoring relationships. This study presented a positive direction in addressing the gaps in the body of knowledge related to women and leadership development by exploring the experiences of women in senior leadership positions in the aerospace industry. Implications for social change include informing organizations and women about specific leadership development practices as one way to promote more women into leadership positions thus reducing the gap between the number of men and women leaders.

Such a measurement would be particularly useful in the Caltech coaxial magnetized plasma gun, an experiment used for fundamental studies relevant to spheromak formation, astrophysical jet formation/propagation, solar coronal physics, and the general behavior of twisted magnetic flux tubes that intercept a boundary. In order to measure the field strength in the Caltech experiment, a non-perturbing spectroscopic method is being implemented to observe the Zeeman splitting in the emission spectra. The method is based on polarization-resolving spectroscopy of the Zeeman-split ? components, a technique previously used in both solar and laboratory plasmas. We have designed and constructed an optical system that can simultaneously detect left- and right-circularly polarized emission with both high throughput and small extinction ratio. The system will be used on the 489.5 nm NII line, chosen because of its simple Zeeman structure and minimal Stark broadening.

The effects of limiting punitive damage awards.  

PubMed

In response to concerns that jury awards in tort cases are excessive and unpredictable, nearly every state legislature has enacted some version of tort reform that is intended to curb extravagant damage awards. One of the most important and controversial reforms involves capping (or limiting) the maximum punitive damage award. We conducted a jury analogue study to assess the impact of this reform. In particular, we examined the possibility that capping punitive awards would cause jurors to inflate their compensatory awards to satisfy their desires to punish the defendant, particularly in situations where the defendant's conduct was highly reprehensible. Relative to a condition in which punitive damages were unlimited, caps on punitive damages did not result in inflation of compensatory awards. However, jurors who had no option to award punitive damages assessed compensatory damages at a significantly higher level than did jurors who had the opportunity to do so. We discuss the policy implications of these findings. PMID:11480801

Aerospace toxicology overview: aerial application and cabin air quality.  

PubMed

Aerospace toxicology is a rather recent development and is closely related to aerospace medicine. Aerospace toxicology can be defined as a field of study designed to address the adverse effects of medications, chemicals, and contaminants on humans who fly within or outside the atmosphere in aviation or on space flights. The environment extending above and beyond the surface of the Earth is referred to as aerospace. The term aviation is frequently used interchangeably with aerospace. The focus of the literature review performed to prepare this paper was on aerospace toxicology-related subject matters, aerial application and aircraft cabin air quality. Among the important topics addressed are the following: · Aerial applications of agricultural chemicals, pesticidal toxicity, and exposures to aerially applied mixtures of chemicals and their associated formulating solvents/surfactants The safety of aerially encountered chemicals and the bioanalytical methods used to monitor exposures to some of them · The presence of fumes and smoke, as well as other contaminants that may generally be present in aircraft/space vehicle cabin air · And importantly, the toxic effects of aerially encountered contaminants, with emphasis on the degradation products of oils, fluids, and lubricants used in aircraft, and finally · Analytical methods used for monitoring human exposure to CO and HCN are addressed in the review, as are the signs and symptoms associated with exposures to these combustion gases. Although many agricultural chemical monitoring studies have been published, few have dealt with the occurrence of such chemicals in aircraft cabin air. However, agricultural chemicals do appear in cabin air; indeed, attempts have been made to establish maximum allowable concentrations for several of the more potentially toxic ones that are found in aircraft cabin air. In this article, I emphasize the need for precautionary measures to be taken to minimize exposures to aerially encountered chemicals, or aircraft cabin air contaminants and point out the need for future research to better address toxicological evaluation of aircraft-engine oil additives.

Actively controlled shaft seals for aerospace applications  

NASA Astrophysics Data System (ADS)

This study experimentally investigates an actively controlled mechanical seal for aerospace applications. The seal of interest is a gas seal, which is considerably more compact than previous actively controlled mechanical seals that were developed for industrial use. In a mechanical seal, the radial convergence of the seal interface has a primary effect on the film thickness. Active control of the film thickness is established by controlling the radial convergence of the seal interface with a piezoelectric actuator. An actively controlled mechanical seal was initially designed and evaluated using a mathematical model. Based on these results, a seal was fabricated and tested under laboratory conditions. The seal was tested with both helium and air, at rotational speeds up to 3770 rad/sec, and at sealed pressures as high as 1.48 x 10(exp 6) Pa. The seal was operated with both manual control and with a closed-loop control system that used either the leakage rate or face temperature as the feedback. The output of the controller was the voltage applied to the piezoelectric actuator. The seal operated successfully for both short term tests (less than one hour) and for longer term tests (four hours) with a closed-loop control system. The leakage rates were typically 5-15 slm (standard liters per minute), and the face temperatures were generally maintained below 100C. When leakage rate was used as the feedback signal, the setpoint leakage rate was typically maintained within 1 slm. However, larger deviations occurred during sudden changes in sealed pressure. When face temperature was used as the feedback signal, the setpoint face temperature was generally maintained within 3 C, with larger deviations occurring when the sealed pressure changes suddenly. the experimental results were compared to the predictions from the mathematical model. The model was successful in predicting the trends in leakage rate that occurred as the balance ratio and sealed pressure changed, although the leakage rates were not quantitatively predicted with a high degree of accuracy. This model could be useful in providing valuable design information for future actively controlled mechanical seals.

Potential aerospace applications of high temperature superconductors  

NASA Astrophysics Data System (ADS)

The recent discovery of High Temperature Superconductors (HTS) with superconducting transition temperature, T(sub c), above the boiling point of liquid nitrogen has opened the door for using these materials in new and practical applications. These materials have zero resistance to electric current, have the capability of carrying large currents and as such have the potential to be used in high magnetic field applications. One of the space applications that can use superconductors is electromagnetic launch of payloads to low-earth-orbit. An electromagnetic gun-type launcher can be used in small payload systems that are launched at very high velocity, while sled-type magnetically levitated launcher can be used to launch larger payloads at smaller velocities. Both types of launchers are being studied by NASA and the aerospace industry. The use of superconductors will be essential in any of these types of launchers in order to produce the large magnetic fields required to obtain large thrust forces. Low Temperature Superconductor (LTS) technology is mature enough and can be easily integrated in such systems. As for the HTS, many leading companies are currently producing HTS coils and magnets that potentially can be mass-produced for these launchers. It seems that designing and building a small-scale electromagnetic launcher is the next logical step toward seriously considering this method for launching payloads into low-earth-orbit. A second potential application is the use of HTS to build sensitive portable devices for the use in Non Destructive Evaluation (NDE). Superconducting Quantum Interference Devices (SQUID's) are the most sensitive instruments for measuring changes in magnetic flux. By using HTS in SQUID's, one will be able to design a portable unit that uses liquid nitrogen or a cryocooler pump to explore the use of gradiometers or magnetometers to detect deep cracks or corrosion in structures. A third use is the replacement of Infra-Red (IR) sensor leads on Earth Orbit Systems (EOS) with HTS leads. IR detectors on these EOS missions are cooled to a 4.2K to improve their signal to noise ratio. They are connected to data acquisitions systems using manganin wires (low thermal conductors) to reduce the heat load on the cryogen. Replacing these wires with HTS leads will increase the lifetime of these missions by about 50 percent. This is a promising application that is ready for actual implementation on such systems. The analysis also show that an the number of IR detectors increase in larger EOS systems, substantial increase in the lifetime of each mission will be realized by using HTS leads instead of the manganin ones.

Development of a polarization resolved spectroscopic diagnostic for measurements of the vector magnetic field in the Caltech coaxial magnetized plasma jet experiment.  

PubMed

In the Caltech coaxial magnetized plasma jet experiment, fundamental studies are carried out relevant to spheromak formation, astrophysical jet formation/propagation, solar coronal physics, and the general behavior of twisted magnetic flux tubes that intercept a boundary. In order to measure the spatial profile of the magnetic field vector for understanding the underlying physics governing the dynamical behavior, a non-perturbing visible emission spectroscopic method is implemented to observe the Zeeman splitting in emission spectra. We have designed and constructed a polarization-resolving optical system that can simultaneously detect the left- and right-circularly polarized emission. The system is applied to singly ionized nitrogen spectral lines. The magnetic field strength is measured with a precision of about ±13 mT. The radial profiles of the azimuthal and axial vector magnetic field components are resolved by using an inversion method. PMID:23464211

Scarf Award for outstanding dissertation research that contributes directly to solar-planetary science. Chen will receive a cash award of $1,000 and present an invited paper on the subject of her dissertation in a SPA-Magnetospheric Physics session at the meeting.Chen received her Ph.D. in physics from the University of California, Los Angeles, in September 1990. Her dissertation on “The Polar Wind and Ionic Outflow” involved the oretical analysis, numerical simulations, and comparison with observational data. Advised by Maha Ashour-Abdalla, Chen incorporated kinetic processes such as ion heating into a macroscopic hydrodynamical model of the polar wind in order to investigate “non-classical” effects in the polar wind. She also worked closely on this subject with Thomas E. Holzer of the NCAR High Altitude Observatory. In collaboration with William K. Peterson of Lockheed and Thomas E. Moore of NASA Marshall Space Flight Center, Chen analyzed measurements from the Dynamics Explorer 1 spacecraft of upflowing ion streams in the polar cap region. These data were used to guide the theoretical modeling.

We present the optical effects of different tests that simulate the aerospace environment on the liquid-crystal variable retarders (LCVRs) used in the Imaging Magnetograph eXperiment postfocal instrument of the SUNRISE payload within the NASA Long Duration Balloon program. Analysis of the influence of vacuum,temperature, vibration, and gamma and ultraviolet radiation is performed by measuring the effects of these tests on the optical retardance, the response time, the wavefront distortion,and the transmittance, including some in situ measurements. Outgassing measurements of the different parts of the LCVRs are also shown. From the results obtained it can be concluded that these optical devices are suitable and seem to be excellent candidates for aerospace platforms.

Measurement of Baseline and Orientation between Distributed Aerospace Platforms  

PubMed Central

Distributed platforms play an important role in aerospace remote sensing, radar navigation, and wireless communication applications. However, besides the requirement of high accurate time and frequency synchronization for coherent signal processing, the baseline between the transmitting platform and receiving platform and the orientation of platform towards each other during data recording must be measured in real time. In this paper, we propose an improved pulsed duplex microwave ranging approach, which allows determining the spatial baseline and orientation between distributed aerospace platforms by the proposed high-precision time-interval estimation method. This approach is novel in the sense that it cancels the effect of oscillator frequency synchronization errors due to separate oscillators that are used in the platforms. Several performance specifications are also discussed. The effectiveness of the approach is verified by simulation results.

NASA Aerospace Flight Battery Systems Program: An update  

NASA Astrophysics Data System (ADS)

The major objective of the NASA Aerospace Flight Battery Systems Program is to provide NASA with the policy and posture to increase and ensure the safety, performance, and reliability of batteries for space power systems. The program was initiated in 1985 to address battery problems experienced by NASA and other space battery users over the previous ten years. The original program plan was approved in May 1986 and modified in 1990 to reflect changes in the agency's approach to battery related problems that are affecting flight programs. The NASA Battery Workshop is supported by the NASA Aerospace Flight Battery Systems Program. The main objective of the discussions is to aid in defining the direction which the agency should head with respect to aerospace battery issues. Presently, primary attention in the Battery Program is being devoted to issues revolving around the future availability of nickel-cadmium batteries as a result of the proposed OSHA standards with respect to allowable cadmium levels in the workplace. The decision of whether or not to pursue the development of an advanced nickel-cadmium cell design and the qualification of vendors to produce cells for flight programs hinges on the impact of the OSHA ruling. As part of a unified Battery Program, the evaluation of a nickel-hydrogen cell design options and primary cell issues are also being pursued to provide high performance NASA Standards and space qualified state-of-the-art cells. The resolution of issues is being addressed with the full participation of the aerospace battery community.

Guided wave interaction with aerospace aluminium stringer feet  

NASA Astrophysics Data System (ADS)

Acoustic Emission has shown itself to be a valuable technology for reliably detecting damage initiation and growth in large structures. Monitoring of a structure, throughout its life, is possible with sparse sensor arrays. However aerospace structures can be geometrically complex and contain many structural features, the most common being stringers. Stringers are arranged in a way that they can span the length of the wings or fuselage, separated by less than 200mm in certain cases. Therefore it is almost inevitable that, for any reasonable sensor spacing, acoustic emission events propagating guided waves will interact with multiple stringers. A large aerospace aluminium panel is used to minimise the effects of edge reflections and to allow the two fundamental guided wave modes to separate before reception. It is shown that stringer foot height has a noticeable impact on guided wave propagation, for typical aerospace arrangements. A reduction in transmitted signal amplitude was noted as the stringer thickness was increased. However a local maximum was seen when the stringer foot thickness was equal to that of the plate thickness. This paper discusses quantitative analysis of stringer interaction with the fundamental guided wave modes. The effect of the stringer as a feature has been divided into three main interactions; stringer dimensions, coupling media and riveting. Stringer dimensions and coupling media interactions has been investigated here to quantify their effect on transmission and reflection of the fundamental guided wave modes.

Multiple regression analyses in the prediction of aerospace instrument costs  

NASA Astrophysics Data System (ADS)

The aerospace industry has been investing for decades in ways to improve its efficiency in estimating the project life cycle cost (LCC). One of the major focuses in the LCC is the cost/prediction of aerospace instruments done during the early conceptual design phase of the project. The accuracy of early cost predictions affects the project scheduling and funding, and it is often the major cause for project cost overruns. The prediction of instruments' cost is based on the statistical analysis of these independent variables: Mass (kg), Power (watts), Instrument Type, Technology Readiness Level (TRL), Destination: earth orbiting or planetary, Data rates (kbps), Number of bands, Number of channels, Design life (months), and Development duration (months). This author is proposing a cost prediction approach of aerospace instruments based on these statistical analyses: Clustering Analysis, Principle Components Analysis (PCA), Bootstrap, and multiple regressions (both linear and non-linear). In the proposed approach, the Cost Estimating Relationship (CER) will be developed for the dependent variable Instrument Cost by using a combination of multiple independent variables. "The Full Model" will be developed and executed to estimate the full set of nine variables. The SAS program, Excel, Automatic Cost Estimating Integrate Tool (ACEIT) and Minitab are the tools to aid the analysis. Through the analysis, the cost drivers will be identified which will help develop an ultimate cost estimating software tool for the Instrument Cost prediction and optimization of future missions.

The appeal of online education and distance learning as an educational alternative is ever increasing. To support and accommodate the over-specialized knowledge available by different experts, information technology can be employed to develop virtual distributed pools of autonomous specialized educational modules and provide the mechanisms for retrieving and sharing them. New educational standards such as SCORM and Healthcare LOM enhance this process of sharing by offering qualities like interoperability, accessibility, and reusability, so that learning material remains credible, up-to-date and tracks changes and developments of medical techniques and standards through time. Given that only a few e-learning courses exist in aerospace medicine the material of which may be exchanged among teachers, the aim of this paper is to illustrate the procedure of creating a SCORM compliant course that incorporates notions of recent advances in social web technologies. The course is in accordance with main educational and technological details and is specific to pulmonary disorders in aerospace medicine. As new educational trends place much emphasis in continuing medical education, the expansion of a general practitioner's knowledge in topics such as aviation and aerospace pulmonary disorders for crew and passengers becomes a societal requirement.

PREFACE: Trends in Aerospace Manufacturing 2009 International Conference  

NASA Astrophysics Data System (ADS)

The aerospace industry is rapidly changing. New aircraft structures are being developed and aero-engines are becoming lighter and more environmentally friendly. In both areas, innovative materials and manufacturing methods are used in an attempt to get maximum performance for minimum cost. At the same time, the structure of the industry has changed and there has been a move from large companies designing, manufacturing components and assembling aircraft to one of large global supply chains headed by large system integrators. All these changes have forced engineers and managers to bring in innovations in design, materials, manufacturing technologies and supply chain management. In September 2009, the Advanced Manufacturing Research Centre (AMRC) at the University of Sheffield held the inaugural Trends in Aerospace Manufacturing conference (TRAM09). This brought together 28 speakers over two days, who presented in sessions on advanced manufacturing trends for the aerospace sector. Areas covered included new materials, including composites, advanced machining, state of the art additive manufacturing techniques, assembly and supply chain issues.

Requirements for effective use of CFD in aerospace design  

NASA Astrophysics Data System (ADS)

This paper presents a perspective on the requirements that Computational Fluid Dynamics (CFD) technology must meet for its effective use in aerospace design. General observations are made on current aerospace design practices and deficiencies are noted that must be rectified for the U.S. aerospace industry to maintain its leadership position in the global marketplace. In order to rectify deficiencies, industry is transitioning to an integrated product and process development (IPPD) environment and design processes are undergoing radical changes. The role of CFD in producing data that design teams need to support flight vehicle development is briefly discussed. An overview of the current state of the art in CFD is given to provide an assessment of strengths and weaknesses of the variety of methods currently available, or under development, to produce aerodynamic data. Effectiveness requirements are examined from a customer/supplier view point with design team as customer and CFD practitioner as supplier. Partnership between the design team and CFD team is identified as an essential requirement for effective use of CFD. Rapid turnaround, reliable accuracy, and affordability are offered as three key requirements that CFD community must address if CFD is to play its rightful role in supporting the IPPD design environment needed to produce high quality yet affordable designs.

The Guggenheim Aeronautics Laboratory at Caltech and the creation of the modern rocket motor (1936-1946): How the dynamics of rocket theory became reality  

NASA Astrophysics Data System (ADS)

This thesis explores and unfolds the story of discovery in rocketry at The California Institute of Technology---specifically at Caltech's Guggenheim Aeronautics Laboratory---in the 1930s and 1940s. Caltech was home to a small group of engineering students and experimenters who, beginning in the winter of 1935--1936, formed a study and research team destined to change the face of rocket science in the United States. The group, known as the Guggenheim Aeronautics Laboratory (GALCIT, for short) Rocket Research Group, invented a new type of solid-rocket propellant, made distinct and influential discoveries in the theory of rocket combustion and design, founded the Jet Propulsion Laboratory, and incorporated the first American industrial concern devoted entirely to rocket motor production: The Aerojet Corporation. The theoretical work of team members, Frank Malina, Hsueh-shen Tsien, Homer J. Stewart, and Mark Mills, is examined in this thesis in detail. The author scrutinizes Frank Malina's doctoral thesis (both its assumptions and its mathematics), and finds that, although Malina's key assertions, his formulae, hold, his work is shown to make key assumptions about rocket dynamics which only stand the test of validity if certain approximations, rather than exact measurements, are accepted. Malina studied the important connection between motor-nozzle design and thrust; in his Ph.D. thesis, he developed mathematical statements which more precisely defined the design/thrust relation. One of Malina's colleagues on the Rocket Research Team, John Whiteside Parsons, created a new type of solid propellant in the winter of 1941--1942. This propellant, known as a composite propellant (because it simply was a relatively inert amalgam of propellant and oxidizer in non-powder form), became the forerunner of all modern solid propellants, and has become one of the seminal discoveries in the field of Twentieth Century rocketry. The latter chapters of this dissertation discuss the creation of the jet Propulsion Laboratory, the founding of the Aerojet Corporation, and emphasizes the issue of JPL's close relation to military development of the rocket becomes a core subject of this thesis. Cooperation between engineers in an academic setting and the military was not merely inevitable in the 1940s---it was actively fostered and proved quite profitable to all concerned. The deep relationship between the Guggenheim Aeronautics Laboratory and the Army Air Force was one model of the evolution of a permanent institutional edifice, weaving academic research and military end-use together. The dissertation concludes that what began as a modest effort to understand rocket theory in greater depth led within ten years to both research and development tracks which have profoundly altered the technological and military definition of modern history.

Hybrid planar lightwave circuits for defense and aerospace applications  

NASA Astrophysics Data System (ADS)

We present innovations in Planar Lightwave Circuits (PLCs) that make them ideally suited for use in advanced defense and aerospace applications. We discuss PLCs that contain no micro-optic components, no moving parts, pose no spark or fire hazard, are extremely small and lightweight, and are capable of transporting and processing a range of optical signals with exceptionally high performance. This PLC platform is designed for on-chip integration of active components such as lasers and detectors, along with transimpedance amplifiers and other electronics. These active components are hybridly integrated with our silica-on-silicon PLCs using fully-automated robotics and image recognition technology. This PLC approach has been successfully applied to the design and fabrication of multi-channel transceivers for aerospace applications. The chips contain hybrid DFB lasers and high-efficiency detectors, each capable of running over 10 Gb/s, with mixed digital and analog traffic multiplexed to a single optical fiber. This highlyintegrated functionality is combined onto a silicon chip smaller than 4 x 10 mm, weighing < 5 grams. These chip-based transceivers have been measured to withstand harsh g-forces, including sinusoidal vibrations with amplitude of 20 g acceleration, followed by mechanical shock of 500 g acceleration. The components operate over a wide range of temperatures, with no device failures after extreme temperature cycling through a range of > 125 degC, and more than 2,000 hours operating at 95 degC ambient air temperature. We believe that these recent advancements in planar lightwave circuits are poised to revolutionize optical communications and interconnects in the aerospace and defense industries.

1984 James B. Macelwane Awards  

NASA Astrophysics Data System (ADS)

Mary Hudson is being honored as one of the 1984 James B. Macelwane award winners because her theoretical research on the microphysics of magnetospheric plasmas has been at the forefront of the field, has inspired many experimental and theoretical studies, and has stimulated her colleagues and students.From her earliest work as a graduate student, Mary has displayed a pronounced talent for recognizing a challenging problem, understanding the experimental data, formulating a theoretical approach, theoretically interpreting the data, and working with experimentalists on the consequences of her theory. Her Ph.D. research, on the equatorial Rayleigh-Taylor instability, called Equatorial Spread F, was undertaken on her own initiative and produced a sophisticated collisional, linear instability analysis which showed that drift waves play an important role in this phenomenon. Her collaborations with experimentalists verified this result and led to an analytic nonlinear solution for the evolution of two-dimensional plasma bubbles that are now known to occur in Equatorial Spread F.
