ASTROPOWER IS PROPOSING THE DEVELOPMENT OF AN ULTRA-LIGHTWEIGHT, HIGH PERFORMANCE, THIN LIGHT TRAPPING GAAS SOLAR CELL FOR ADVANCED SPACE POWER SYSTEMS. A THIN DEVICE LEADS TO HIGHER PERFORMANCE IN TERMS OF OPEN CIRCUIT VOLTAGE, RADIATION RESISTANCE, AND SPECIFIC POWER. IN A THIN DEVICE, THE INCORPORATION OF LIGHT TRAPPING TO EXTEND THE OPTICAL PATH LENGTH PERMITS GREATER CURRENT GENERATIC THAN CA ...

TRADITIONALLY, THE DETONATION HAS BEEN TREATED BY THE SHOCK THEORY, AND EXPLOSIVES AND PROPELLANTS HAVE BEEN CONSIDERED AS ENERGETIC FLUIDS. MANY SOLID PROPERTIES HAVE NOT BEEN MEASURED AND ARE NOT AVAILABLE FROM THE HANDBOOKS. RECENT RESULTS IN MUNITION SENSITIVITY STUDIES SHOW THAT SHEARING IS ONE OF THE MAIN MECHANISMS IN CAUSING DETONATION, AND IS CONTROLLED BY CERTAIN SOLID PROPERTIES. IN THE ...

THIS PROPOSAL DESCRIBES THE EFFORTS REQUIRED TO STUDY THE EFFECTS OF VARIOUS MATERIALS ON THE REDUCTION OF ELECTRONIC INTERFACE IN THE PLASMA OF A RE-ENTRY VEHICLE HEAT SHIELD. A FUNDEMENTAL UNDERSTANDING OF THE MECHANISM BY MEANS OF WHICH THESE MATERIALS ACHIEVE A REDUCTION IN ELECTRONIC INTERFERENCE IS THE GOAL OF THE PROPOSED INVESTIGATIONS, IN WHICH THE GSI FLAME TEST APPARATUS IS USED TO DETE ...

THERE IS A RAPIDLY GROWING NEED FOR TOOLS FOR THE DESIGN AND SYNTHESISOF ELECTRONIC SYSTEMS AND MULTI-DEVICE CIRCUITS: TO SUPPORT GREATER CLOCK SPEEDS; PACKAGING DENSITITES AND CIRCUIT COMPLEXITY; TO ENABLE DESIGNERS TO RAPIDLY CREATE AND COMPARE ALTERNATIVE DESIGN CONCEPTS; TO ELIMINATE MULTIPLE RE-DESIGN CYCLES; AND TO ENABLE REUSE OF PRIOR DESIGN KNOWLEDGE. THERE ARE NO CAE TOOLS COMMERCIALLY A ...

PHASE I OF THIS PROGRAM WILL OPTIMIZE THE GROWTH OF LATTICE MATCHED INGAAS/INALAS ON INP FOR EOIC APPLICATIONS THROUGH THE USE ON INNOVATIVE MOLECULAR BEAM EPITAXIAL (MBE) GROWTH AND CALIBRATION PROCEDURES. THE PROGRAM WILL STUDY THE EFFECTS OF SLIGHT LATTICE MISMATCH ON THICK EPITAXIAL LAYERS. THE PROGRAM WILL DEVELOP A MORE ACCURATE MEANS OF SETTING THE MOLECULAR BEAM RATIOS AS WELL AS NOVEL, EA ...

A NOVEL TECHNIQUE IS PROPOSED WHICH WILL ALLOW THE RESOLUTION, ANALYSIS, AND SUPPRESSION OF THE MULTIPATH COMPONENTS OF AN ANTENNA RANGE MEASUREMENT TEST SIGNAL% THE TECHNIQUE ACHIEVES TIME DELAY RESOLUTION MUCH FINER THAN THE RECIPROCAL OF THE BANDWIDTH OF THE TEST SIGNAL* AS A RESULT, ULTRA LOW SIDELOBE ANTENNA MEASUREMENTS CAN BE MADE IN REAL TIME WITHOUT USING AN ULTRA WIDEBAND TEST SIGNAL AND ...

THIS DOCUMENT IS AN SBIR TECHNICAL PROPOSAL SUBMITTED TO THEFEDERAL AVIATION ADMINISTRATION BY DELTA INFORMATION SYSTEMS, INC. IN RESPONSE TO SBIR SOLICITATION NUMBER 91-FA11. THE PURPOSE OF THE PROPOSED PROGRAM IS TO INVESTIGATE, ANALYZE, AND DESIGN ALTERNATIVE DATA COMPRESSION SYSTEMS TO EFFICIENTLY TRANSMIT AIR TRAFFIC CONTROL DISPLAY DATA FROM MAJOR AIRPORTS TO SMALLER SATELLITE AIRPORTS ON LI ...

THIS PROJECT WILL IDENTIFY AND CHARACTERIZE CANDIDATE SURFACTANTS FOR USE IN TWO DIFFERENT EXPLOSIVES SYSTEMS. THE OBJECTIVE IS TO IMPROVE PROCESSABILITY BY REDUCING VISCOSITY BY BETTER DISPERSION OF THE FILLERS. THIS WILL PERMIT HIGHER EXPLOSIVE FILLER LOADING (PBX AND TNT) AND/OR IMPROVE THE SUSPENSION OF SOLIDS (TNT). THIS PROJECT HAS A HIGH PROBABILITY OF SUCCESS. THE PROGRAM WILL SYSTEMATICAL ...

GAASP SOLAR CELLS PLACED ON TOP OF CONVENTIONAL SILICON SOLAR CELL ARRAYS CAN INCREASE THE ENERGY CONVERSION EFFICIENCY OF THE SYSTEM AS MUCH AS 100%. ASTROPOWER DIVISION OF ASTROSYSTEMS, INC. PROPOSES TO DEVELOP A HIGH BAND GAP TOP SOLAR CELL FOR ATTACHMENT TO CONVENTIONALS ILICON SOLAR CELLS. TRANSPARENT GAP SUBSTRATES WILL BE USED WITH EPITAXIALLY GROWN LAYERS OF GAASPH HAVING A BAND GAP OF 1.7 ...

SOLID LUBRICATION OFFERS SIGNIFICANT ADVANTAGES FOR ROLLING ELEMENT BEARINGS AND MACHINERY EXPOSED TO EXTREME CONDITIONS. A MAJOR CONSTRAINT IS THAT CURRENT DESIGNS FOR SUCH BEARINGS ARE BASED ON HYDRODYNAMIC LUBRICATION (OIL AND GREASE). THE CHALLENGE IS TO IDENTIFY A NEW CONCEPT THAT FOCUSES THE REQUIREMENTS FOR THE EFFECTVE USE OF SOLIDS AND A METHODOLOGY FOR SOLID LUBRICANT-BEARING SYSTEM INTE ...
