As the unmanned exploration of Mars and Venus becomes more of a focus area at NASA, inflatable, rigidizable wings will become an enabling technology. The successful development of this type of wing will also have significant military applications. The utility of unmanned aerial vehicles (UAVs) for the military has been dramatically demonstrated in the conflict in Afghanistan. Rigidization of infla ...

IT IS PROPOSED TO DETERMINE THE FEASIBILITY OF USING A NONEQUILIBRIUM PLASMA JET, DEVELOPED AT AEROCHEM OVER THE PAST QUARTER CENTURY, AS A MEANS OF ENHANCING IGNITION AND FLAME STABILIZATION IN AIR-BREATHING ENGINES AND IN SUPERSONIC COMBUSTION. SPECIFICALLY, WE WILL DETERMINE; IF IGNITION OF LEAN OR LOW PRESSURE MIXTURES CAN BE MADE MORE RELIABLE; IF FLAME HOLDING LIMITS CAN BE BROADENED, E.G., ...

DIRECT COMPUTATION OF TURBULENCE NOISE IS A LOGICAL APPLICATION FOR ADVANCED COMPUTATIONAL FLUID DYNAMICS, CFD, PROGRAMS RUN ON SUPERCOMPUTERS. THIS WOULD ELIMINATE THE HIGHLY EMPIRICAL ASPECTS OF PRESENT NOISE PREDICTION TECHNIQUES AND ENABLE STUDY OF ADVANCED HYPERSONIC PROPULSION SYSTEMS. HOWEVER, MANY OF THE SAME PERSISTENT PROBLEMS OF IMPLEMENTATION THAT EXIST IN AEROACOUSTIC THEORY AND MEASU ...

THE GENERIC ARTIFICIAL INTELLIGENCE EXPERT SYSTEM FOR SPACE-STATION APPLICATIONS WILL BE USER-FRIENDLY AND WILL UTILIZE A HIERARCHY OF FRAMES FOR DATA INPUT, AUTOMATIC FAULT DIAGNOSIS AND ANALYSIS AND REPAIR FUNCTIONS. IT WILL PROVIDE PROMPT DIAGNOSIS AND SUGGESTIONS FOR SYSTEM REPAIR. IT WILL PROVIDE AS MUCH AUTOMATION AS POSSIBLE FOR REPAIR FUNCTIONS. THE DESIGN WILL BE APPROPRIATE FOR INTERFACI ...

Accelerated development of directed energy technologies has presented new problems to mission planners and weapon operators regarding the capabilities, lethality and performance of weapon systems. The Emerging Weapons Technology Evaluation Model willaddress these shortcomings by providing users of varying technical expertise 1) the ability to model a variety of weapons in various mission scenario ...

THE DIGITAL ACTIVE MATERIALS-PROCESSING PLATFORM EFFORT BE- ING PROPOSED HERE SEEKS TO DEVELOP AN ACTIVELY STABILIZD PLATFORM UPON WHICH MICRO-G MATERIALS PROCESSING EXPERIMENTSCAN BE PERFORMED IN SPACE. WITH THE SUC- CESSFUL COMPLETION OF THE TWO-STEP PHASE I WORKPLAN APPLIED TECHNOLOGY ASSOCIATES (ATA) HAS CLEARLY AND SUCCINTLY DEFINED THE PROBLEM OF PLATFORM ISOLATION IN SPACE AND HAS COMPLETEL ...

This firm has, in ongoing work in collaboration with the Air Force, NASA and JPL, developed a unique Variable Emittance technology based on the electrochromism of unique Conducting Polymers. This comprises thin (< 0.5 mm), flexible, lightweight (0.16 g/cm^2), variable area (0.5 cm^2 to 0.5 m^2), very low cost flat panels. Delta Emittance (DE) of 0.33 in space-qualified devices, and 0.53 in vacuum- ...

COMPUTATIONAL FLUID DYNAMICS (CFD) TOOLS HAVE NOW DEVELOPED TO THE POINT WHERE THEY CAN BE RELIABLY USED FOR THE DESIGN,EVALUATION, AND ANALYSIS OF SUCH HIGH-PERFORMANCE GAS TURBINES AS THOSE USED IN MODERN AERONAUTICAL PROPULSION SYSTEMS. FOR THESE APPLICATIONS, IT IS NECESSARY TO USE A THREE-DIMENSIONAL VISCOUS CFD CODE THAT COMBINES EFFICIENCY,ACCURACY, AND USER-FRIENDLINESS. FOR AXIAL TURBOMAC ...
