ADVANCED COMPOSITES HAVE POTENTIAL FOR EFFECTING WEIGHT SAVINGS AND PROVIDING CORROSION RESISTANCE TO A VARIETY OF MILTARY APPLICATIONS. THE MK112 ASROC LAUCHER MODS 1-8 AND GUIDE, ES114, HAVE BEEN IDENTIFIED AS HAVING EXPERINECED CORROSION AND WEIGHT PROBLEMS. THERE ARE A VARIETY OF RESINS AND FIBERS AVAILABLE FOR USE AS STRUCTURAL MATERIALS THESE INCLUDE GLASS, KEVLAR & CARBON FIBERS,AND POLYEST ...

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 ...

HEAT EXCHANGE MATRIX THE FUNCTION OF A HEAT EXCHANGER IS DEPENDENT UPON THE AREA OF EXPOSURE TO THE FLUIDS IN PROCESS. FINS ARE COMMONLY USED TO INCREASE EXTERNAL SURFACE AREAS. TO EXTEND THE INNER SURFACE OF A TUBE OR VESSEL IS MORE DIFFICULT AND THERE IS CURRENTLY NO COST EFFECTIVE METHOD TO DO SO. THIS REDEARCH IS TO DEVELOP THE USE OF A MATRIX COMPOSED OF SMALL, HOLLOW, METAL CYLINDERS, BRAZED ...

FIBER REINFORCED PLASTIC COMPOSITE MATERIALS ARE AVAILABLE WITH A VARIETY OF PERFORMANCE FACTORS AND MANUFACTURING METHODS. THERE ARE SEVERAL STRUCTURAL CONCEPTS THAT CAN BE UTILIZED WITH COMPOSITES. THIS PROJECT IS TO PERFORM A FEASIBILITY STUDY TO DETERMINE THE APPLICABILITY OF FIBER REINFORCED PLASTIC COMPOSITE MATERIALS FOR COMBATANT SUBMARINE STRUCTURES. EXAMPLES OF STRUCTURES TO BE ANALYZED ...

THIS PROPOSAL DESCRIBES THE PHASE I DEVELOPMENT WORK FOR A DUAL OUTPUT, "FAIL-SAFE" FIBER OPTIC FUZE CONTACT TRANSDUCER FOR USE IN AIRBORNE MISSILE APPLICATIONS. THE SENSOR WOULD EXPLOIT THE SENSITIVITY OF SPECIALIZED OPTICAL FIBERS TO MICROBENDING: THIS PHENOMENON WOULD BE USED TO DETECT PHYSICAL DEFORMATION OF A MISSILE SKIN. THE OBJECTIVES OF THE PHASE I EFFORT INCLUDE RESEARCHING AND IDENTIFYI ...

OPTOELECTRONIC SOURCES, INTEGRATED AS MONOLITHIC ELEMENTS ON SILICON VLSI CHIPS, OFFER IMPORTANT ADVANTAGES IN THE TRANSMISSION OF INFORMATION WITHIN THE CHIP OR BETWEEN CHIPS IN ADVANCED COMPUTER SYSTEMS. THE SPEED OF OPTICAL-INTEGRATED VLSI DEVICES IS EXPECTED TO BE CONSIDERABLY HIGHER THAN EQUIVALENT VLSI WITH METALLIC INTERCONNECTS, DUE TO ABSENCE OF THE RC DELAY INHERENT IN THE METALLIC CONDU ...

THE ULTIMATE HIGH-EFFICIENCY CRYSTALLINE SILICON SOLAR CELL DESIGN CONSISTS OF A THIN FILM OF ELECTRICALLY-ACTIVE SILICON EPITAXIALLY GROWN ON AN OXIDE-OVERCOATED, INFRARED-TRANSPARENT GALLIUM PHOSPHIDE (GAP) SUBSTRATE. IN ADDITION TO HIGH CONVERSION EFFICIENCY AND INTRINSIC RADIATION RESISTANCE DUE TO THE THIN ACTIVE LAYERS, THIS NOVEL DESIGN HAS SEVERAL UNIQUE PERFORMANCE ENHANCING FEATURES. THE ...

THE LOW COST NON-INTRUSTIVE TORQUE TRANSDUCER IS ADDED TO AN EXISTING DRIVE TRAIN. IT MEASURES DIRECTLY THE ENGINE OUTPUT TORQUE WITH SHORT RESPONSE TIME. THE ANGULAR DEFLECTION AT BOTH ENDS OF THE CRANKSHAFT IS DETECTED BY TWO NON-CONTACTING ENCODER-PICKUP COMBINATIONS. THE PHASE ANGLE BETWEEN THE PULSE TRAINS FROM THE ENCODERS IS PROPORTIONAL TO THE SHAFT DEFLECTION AND THEREFORE A MEASURE OF TH ...

REPAIR OF SHIPBOARD MACHINERY AND EQUIPMENT REQUIRES INFORMATION AND EXPERTISE NOT EASILY AVAILABLE TO SHIPBOARD MAINTENANCE PERSONNEL. WHAT INFORMATION THAT IS AVAILABLE IS GENERALLY EMBEDDED IN TECHNICAL MANUALS OR MAINTENANCE/REPAIR CARDS THAT ARE DIFFICULT TO DECIPHER, BULKY, AND SOMETIMES HARD TO MAINTAIN. A SYSTEM THAT ALLOWED FOR IMPROVED MAINTENANCE AIDING AND GUIDANCE TO NON-EXPERTS WOULD ...

THE SUCCESSFUL GROWTH OF GAAS ON SILICON SUBSTRATES USING DOUBLE SELECTIVE LIQUID EPITAXIAL (DSLE) PROCESS HAS RECENTLY BEEN ACCOMPLISHED. THESE RESULTS SET THE STAGE FOR THE DEVELOPMENT OF AN EXTREMELY USEFUL MATERIAL--LARGE PLANAR WAFERS OF SMOOTH GAAS ON SILICON. DOUBLE SELECTIVE LIQUID PHASE EPITAXY COULD SIGNIFICANTLY REDUCE THE PROBLEMS CAUSED BY LATTICE MISMATCH AND DIFFERENTIAL THERMAL EXP ...
