MATERIAL COMPATABILITY BETWEEN LIQUID METAL CURRENT COLLECTOR ALLOYS AND SOLID METALS ON MATERIAL COLLECTOR SURFACES WILL BE INVESTIGATED. LOW MELTING FUSIBLE TYPE ALLOYS WITH CAPABILITY OF OPERATING AT 200 DEG F OR BELOW WILL BE FEATURED WITH SOME CONSIDERATION OF SUITABLE MATERIALS IN THE 0-500 DEG F RANGE. A THOROUGH LITERATURE SEARCH FOR PERTINENT PHYSICAL, MECHANICAL, AND SURFACE INTERACTIVE ...

WE WISH TO EXPLORE A NEW METHOD FOR PRODUCING VERY HARD DIAMOND-LIKE COATINGS ON OPTICAL COMPONENTS. TO DO THIS, WE WILL USE AN APPARATUS THAT ACCELERATES CARBON IONS FROM A CARBON ARCH OPERATING IN VACUUM. THIS METHOD HAS SEVERAL ADVANTAGES: LARGE QUANTITIES OF IONS CAN BE PRODUCED, SO COATINGS CAN BE MADE RAPIDLY. THE IONS' QUANTITY AND ENERGY, AND THUS THE PROPERTIES OF THE COATINGS RESULTING F ...

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 ...

SUPPLYING ADEQUATE DRINKING WATER TO SOLDIERS ON ARID OR CONTAMINATED BATTLEFIELDS IS A FORMIDABLE PROBLEM. ONE POSSIBLE SOURCE OF WATER IS ENGINE EXHAUST; FOR EXAMPLE, DIESEL EXHAUST CONTAINS 1.1 POUNDS OF WATER VAPOR FOR EACH POUND OF FUEL BURNED. WE PROPOSE TO DEVELOP AN ONBOARD, COMPACT, EASILY MAINTAINED MEMBRANE-BASED SYSTEM THAT CAN RECOVER AND PURIFY WATER FROM COMBAT VEHICLE EXHAUSTS IN A ...

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 ...

DEVELOPMENT IS PROPOSED OF A SMALL, SELF-CONTAINED POWER UNIT CAPABLE OF OPERATING UNATTENDED FOR LONG PERIODS WITH GREAT RELIABILITY. THE UNIT IS INTENDED FOR INCORPORATED AS THE STORAGE BATTERY TRICKLE CHARGER IN A DATA GATHERING AND COMMUNICATIONS SYSTEM FOR THE ARCTIC AND OTHER REMOTE ISOLATED AREAS. THE ENERGY SOURCES ANTICIPATED FOR THE POWERUNIT INCLUDE NUCLEAR (RADIOISOTOPE) AND CHEMICAL ( ...

A PROGRAM IS HEREIN DESCRIBED THAT WILL ESTABLISH THE POSSIBLE IMPROVEMENTS IN EXISTING RESTRAINT SYSTEMS AND THROUGH A CONCEPTUAL AND DEVELOPMENTAL TRADEOFF PHASE, ESTABLISH FEASIBILITY OF AT LEAST ONE CONCEPT THAT WILL REPRESENT A QUANTUM STEP IN THE PERFORMANCE OF CREW RESTRAINT SYSTEMS. THE PROGRAM CONSISTS OF CONCEPT TRADEOFF, OPERATIONAL AND STATIC AND DYNAMIC TESTING, AND SELECTION OF A CON ...
