THE PURPOSE OF THIS RESEARCH EFFORT IS TO EXPLORE THE FEASIBILITY OF DEVELOPING AN GENERIC EXPERT SYSTEM WHICH WOULD BE USED TO DEVELOP EXPERT SYSTEMS TAILORED FOR SPECIFIC APPLICATION. ANALYTICS HAS DEVELOPED AN ADVANCED, PRODUCT-ORIENTED CONCEPT FOR BUILDING, TESTINGS, AND EXECUTING AI APPLICATION SYSTEMS CALLED NINA. THE NINA CONCEPT SUPPORTS THE DESIGN, IMPLEMENTATION, AND EXECUTION OF A WIDE ...

The use of cryogenic solid hydrogen as a rocket propellant may lead to major advances in rocket propulsion. To use solid hydrogen as a propellant requires a system designed to solidfy, store, and transport hydrogen. We propose to study different methods for creating H2 for more than one hour at temperature less than 10 K. Alternative methods of delivering the solid hydrogen to the combustion chamb ...

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 ...

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 ...

TWO YEARS AGO IT WAS EXPERIMENTALLY SHOWN THAT CHARGED WATERDROPLETS COULD KNOCK-DOWN SMOKE RAPIDLY. WE NOW PROPOSE TO TO DEVELOP A DEVICE WHICH USES A CHRGED FINELY POWERED SOLIDAEROSOL TO KNOCK-DOWN SMOKE. USING A SOLID INSTEAD OF A LIQUID AEROSOL HAS SIGNIFICANT ADVANTAGES. THE SOLID PART ICLES CAN BE PRE-FORMED IN A READY-TO-USE STATE. PARTICLE SIZE CAN BE RIGOROUSLY CONTROLLED AND HAVE OPTIMU ...

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 ...
