RELIABILITY AND CIRCUIT DENSITY OF STANDARD ELECTRONIC MODULES (SEM) CAN BE INCREASED SIGNIFICANTLY BY TAILORING THERMOPHYSICAL PROPERTIES OF THE HEAT SINK MATERIALS. NEWLY DEVELOPED TECHNIQUES FOR MANUFACTURING METAL MATRIX COMPOSITES (MMC) BY VAPOR DEPOSITION METHODS WILL BE USED TO DEMONSTRATE LIGHT-WEIGHT, HIGH-PERFORMANCE HEAT SINKS HAVING THERAML CONDUCTIVITIES IN EXCESS OF 300 W/M-K AS WELL ...

LARGE, PERIODIC TEMPERATURE EXCURSIONS CAUSE SIGNIFICANT DIMENSIONAL CHANGES IN LARGE ORBITING SPACE STRUCTURES. SIMILARLY, LARGE GROUND-BASED ANTENNAS AND OPTICAL SYSTEMS ARE SUBJECT TO DIURNAL DIMENSIONAL CHANGES THAT DIMINISH PRECISION AND SENSITIVITY. OUR RECENTLY DEVELOPED GRAPHITE/MAGNESIUM METAL MATRIX COMPOSITES (MMC) HAVE BEEN SHOWN TO BE DIMENSIONALLY STABLE (ZERO CTE AND ZERO HYSTERESIS ...

THIS RESEARCH WILL EXPAND UPON PRELIMINARY STUDIES THAT DEMONSTRATED THE FEASIBILITY OF A SOLID-PHASE, FLOW-THROUGH DEVICE TO CARRY OUT CATALYTIC HYDROGEN TRANSFER REACTIONS. THESE STUDIES USED PALLADIUM-COATED GLASS FIBER FILTERS AS WELL AS SILICA/POLYVINYLCHLORIDE MEMBRANE. PHASE I RESEARCH WILL EVALUATE OTHER SUPPORTS, FOR EXAMPLE, CONTROLLED PORE GLASS AND SILICA/POLYETHYLENE MEMBRANES, AS MAT ...

ALGORITHMS FOR FUSING AND DISPLAY OF ACTIVE AND PASSIVE SENSOR INFORMATION IN THE AIRBORNE TACTICAL ENVIRONMENT ARE OUTLINES. FUSION AND DISPLAY IS PARTITIONED INTO TRACK EXTRAPOLATION, OBSERVATION UPDATE, CORRELATION, GRIDLOCK, ERROR MANAGMENT, AND USER INTERACTION. METHODS OF TESTING THE TOTAL PROCESS WITH SENSOR DATA SIMULATION, CONFLICT SIMULATION, AND MEASURES OF EFFECTIVENESS ARE DISCUSSED.

A NOVEL APPROACH TO ASSESSING THE PERFORMANCE OF COMBINED U.S. NAVAL BATTLE FORCES IS PROPOSED. A MODEL SYSTEM BASED UPON THE ANALYTIC HIERARCHY PROCESS (AHP) AND THE USE OF PAIRWISE COMPARISON MATRICES IS USED TO DETERMINE THE RELATIVE VALUE OF COMPONENTS OF PROJECTING POWER IN THE WARFARE MISSION AREAS. THIS POWER MEASURE COMBINED ESTIMATES OF VULNERABILITY GENERATED IN A SIMILAR FASHION ARE THE ...

THE USMC NIGHT TARGETING SYSTEM (NTS), DESIGNED FOR INSTALLATION IN THE AH-1 ATTACK HELICOPTER BY 1994, IS REPRESENTATIVE OF THE MULTI-SENSOR SYSTEMS REQUIRING COMPREHENSIVE TRAINING FOR SKILLS OF AIR AND GROUND CREWS. DCS WILL CONDUCT A DETAILED STUDY OF TRAINING REQUIREMENTS FOR OPERATOR AND MAINTENANCE PERSONNEL IMPOSED BY THE INCORPORATION OF THE NIGHT TARGETING SYSTEM (NTS) IN THE AH-1W AIRCR ...

DGI CURRENTLY HAS LIGHTWEIGHT, LOW VOLUME ROTARY (I.E., WENKEL) ENGINES CAPABLE OF PRODUCING OUTPUTS IN THE 80 TO 150 HP RANGE. THESE ENGINES HAVE ALUMINUM HOUSING (BODIES) BUT OTHER PARTS OF THE ENGINE ARE STEEL MADE OR OTHER FERROUS METALS. DGI PROPOSES A PROGRAM TO REDUCE THE MAGNETIC SIGNATURE OF A 150 HP ENGINE. THIS WILL BE DONE THROUGH IDENTIFICATION OF THE PARTS OF THE ENGINE WITH MAGNETIC ...

RADIO RELAYS INSTALLED ON ELEVATED PLATFORMS SUCH AS KITES AND BALLOONS CAN EXTEND LINE-OF-SIGHT VHF AND UHF COMMUNICATIOS RANGE BEYOND THE HORIZON. THESE RELAYS MUST BE LIGHTWEIGHT, OPERATE FOR SEVERAL HOURS ON SELF-CONTAINED BATTERIES, AND, BECAUSE THEY ARE EXPENDABLE ITEMS, BE LOW COST. A REPEATER WILL BE DEVELOPED USING CURRENT LOW-COST TECHNOLOGY THAT WILL SIMULTANEOUSLY REPEAT THREE COMMUNIC ...
