THE OBJECTIVE OF THIS PROPOSAL IS THE DEVELOPMENT OF A PULSED MID-IR LASER IN THE 3.5 TO 4.1 MICROMETER ATMOSPHERIC TRANSMISSION WINDOW. SUCH SPECTRAL SOURCE IS RELEVANT TO A VARIETY OF TACTICAL APPLICATIONS. THE DF CHEMICAL LASER HAS BEEN THE CHOICE, BUT SUFFERS FROM WASTE FUEL MANAGEMENT PROBLEMS. NO OTHER EFFICIENT DIRECT LASING SOURCE IS AVAILABLE. TO OBTAIN SUCH A SOURCE, WE PROPOSE THE USE O ...

LOW FLYING AIRCRAFT CANNOT BE DETECTED BY STANDARD RADAR BECAUSE OF INTERFERENCE FROM CLUTTER. THIS PROPOSAL DESCRIBES A COHERENT LASER RADAR SYSTEM APPROACH, CONSISTING OF 2 KM SPACED LASER RADAR SITES THAT SCAN THE SKY IN ELEVATION ANGLE, WHICH CAN DETECT AIRCRAFT BETWEEN THE HORIZON AND 300 METER ALTITUDE. EACH SITE WILL BE BATTERY POWERED AND INTERCONNECTED BY A FIBEROPTIC LOCAL AREA NETWORK T ...

ADVANCED COMPOSITES LABORATORIES WILL DEVELOP AN IMPROVED MOUNTAINEERING SKI FOR MILITARY USE. WE WILL INCORPORATE THE BEST OF DOWNHILL SKI TECHNOLOGY WITH THE BEST OF TELE MARK AND MOUNTAINEERING SKI TECHNOLOGY TO PRODUCE A SKI FOR THE US MARINE CORPS WHICH WILL MEET THE REQUIREMENTS OF THE MARINE CORPS TOICS N86-13. WE WILL USE ADVANCED COMPOSITE MATERIALS TO ALLOW US TO PROVIDE A HIGH PERFORMAN ...

METAL MATRIX COMPOSITES THAT MAY BE USED IN DEEP SPACE VEHICLES MIGHT HAVE SEVERE INTERNAL STRESSES DUE TO THE THERMAL EXPANSION DIFFERENCES BETWEEN THE MATRIX AND THE FIBERS. SINCE THE TEMPERATURES EXPERIENCED WITH THESE VEHICLES MAY BE AS LOW AS A FEW DEGREES ABOVE ABSOLUTE ZERO, IT IS NECESSARY TO KNOW THE THERMAL MECHANICAL BEHAVIOR OF METAL MATRIX COMPOSITES TO BE USED AS STRUCTURAL MATERIALS ...

THERE ARE MANY COMBAT VEHICLE AND EQUIPMENT APPLICATIONS WHERE AN AIR-COOLED HEAT EXCHANGER MUST OPERATE IN AN EN- VIRONMENT WITH HIGH CONCENTRATIONS OF SAND AND DIRT IN THE AMBIENT AIR. CONVENTIONAL COMPACT HEAT EXCHANGERS ARE SSUS- CEPTIBLE TO CLOGGING OF COOLING FINS. ONE APPROACH THAT MAY OFFER SIGNIFICANT ADVANTAGES AND INCREASED PERFORMANCE IN THAT OF A FLUIDIZED BED HEAT EXCHANGER. THE PROP ...

THE STORAGE AND USE OF COMBUSTILBLE LIQUIDS. VARIOUS SCENARIDS ARE POSSIBLE IN WHICH THE LIQUID IS ACCIDENTALLY RELEASED SUCH THAT IS CONTRACTS A HOT SURFACE RESULTING IN A POTENTIAL FIRE OR EXPLOSION HAZARD. THE OPTIMUM DESIGN OF APPROPRIATE SAFETY MEASURES IS SEVERELY HAMPERED BY THE FACT THAT THE THERMAL IGNITION OF LIQUIDS IS A PHENONMENON WHICH IS NOT WELL UNDERSTOOD NOR IS THERE ANY USEFUL E ...

A SERIOUS PROBLEM IN HEAT EXCHANGERS WHERE ATMOSPHERIC AIR IS COOLED TO CRYOGENIC TEMPERATURES IS THAT THE AMBIENT WATER VAPOR AND CO(2) FREEZE ONTO THE HEAT TRANSFER SURFACES. AS THE SOLID DEPOSITS ACCUMULATE THEY ADVERSELY AFFECT PERFORMANCE BY DECREASING HEAT EXCHANGER EFFECTIVENESS AND INCREASING PRESSURE DROP. AN INNOVATIVE APPROACH FOR DEALING WITH THE FREEZING PROBLEM WHICH OFFERS SIGNIFICA ...

THE OVERALL OBJECTIVE OF THE PHASE I PROGRAM IS TO DEMONSTRATE THE FEASIBILITY OF NEWLY DEVELOPED ADVANCED PERMEABLE MEMBRANES FOR THE COMBINED DUTIES ON MILITARY AIRCRAFT OF NITROGEN GENERATION TO INERT FUEL TANKS AND OXYGEN GENERATION FOR PILOT BREATHING IN A UNIQUE SYSTEM ARRANGEMENT. THESE COMPACT AND LIGHTWEIGHT MEMBRANES LEND THEMSELVES TO A MORE EFFICIENT OBIGGS/OBOGS DESIGN COMBINATION THA ...
