Cured aircraft composite materials present a particularly difficult challenge for recycling technology. Those materials have mostly thermosetting epoxy matrices and occur in intimate association with metals, paints, and coatings. Current techniques for recycling thermoset composites, mostly for automotive sheet molding compounds (SMC), involve pulverizing the material for use as fillers. Th ...

A novel tertiary recycling process is proposed for investigation as an economical means for recycling shipboard plastic waste. Early development work has shown that this process can convert a wide variety of polymers and composites into low molecular weight hydrocarbons at temperatures below 200'C. The hydrocarbons produced can then be reused as chemicals, fuels, or monomers. Metal, glass, and fil ...

HYPERSONIC AND SUPERSONIC SPEEDS ARE FEASIBLE DUE TO ADVANCES IN AEROSPACE ENGINEERING, VEHICLE DESIGN, AND PROPULSION TECHNOLOGY. THE EFFICIENCIES, RELIABILITY, AND ULTIMATE POTENTIAL OF AIR BREATHING PROPULSION SYSTEMS HINGE UPON NEW MATERIALS THAT CAN SURVIVE THE HARSH COMBUSTION ENVIRONMENTS. HAFNIUM AND ZIRCONIUM CARBIDE AND BORIDE MATRICES ARE CANDIDATE MATERIALS SYSTEMS, BUT ONLY IF MANUFAC ...

MANY INFRARED AND ELECTRO-OPTICAL IMAGING SYSTEMS ARE CONFOUNDED BY FOG AND DUST. MILLIMETER EAVE IMAGING SYSTEMS WOULD NOT BE AFFECTED BY THESE BATTLEFIELD OBSCURANTS. HOWEVER, THE LIQUID HELIUM COOLING REQUIREMENT OF TODAYS HIGH PERFORMANCE LOW NOISE MIXERS IS BLOCKING THE DEPLOYMENT OF ADVANCED MILLIMETER WAVE COMMUNICATIONS AND IMAGING SYSTEMS. IN PRINCIPAL, JOSEPHSON MIXERS FABRICATED WITH TH ...

THE DEVELOPMENT OF COMPACT, HIGH ENERGY DENSITY, HIGH POWER (AND POTENTIALLY C.W.) LASER SYSTEMS CAPABLE OF PROPAGATING THROUGH BOTH AIR AND WATER COULD PAVE THE WAY FOR NEXT GENERATION TACTICAL NAVAL SYSTEMS. APPLICATIONS IN OTHER DEFENSE AREAS AS WELL AS A HOST OF COMMERCIAL APPLICATIONS ARE ALSO POSSIBLE WITH THESE TYPES OF SYSTEMS. WE PROPOSE TO PROVIDE A DETAILED PLAN AND DESIGN OF SPECIFIC E ...

THE INCREASED DEMANDS FOR LARGE SCALE INTEGRATION AND VERY HIGH SPEED PROCESSING OF INFORMATION HAVE LED TO INCREASING DENSITY OF CHIPS IN ELECTRONIC MODULES. THIS, IN TURN, HAS INCREASED DRAMATICALLY THE HEAT GENERATED PER UNIT AREA. IN ORDER TO MEET THE NEW DESIGN SPECIFICATIONS, AN INNOVATIVE HEAT SINK CONCEPT IS PROPOSED. THE HEAT SINK WILL HAVE A THERMAL EXPANSION IN THE RANGE OF 2.8 PPM/DEG ...

Warhead design calculations and weapons effectiveness estimates require a methodology to predict the terminal ballistic structural response and the associated functional damage to operating missile batteries subjected to warhead fragment impacts at speeds up to 16,000 ft/sec. The objectives for the proposed Phase I study effort are to develop a candidate structural representation for the missile b ...

A miniaturized lighter-than-air (LTA) unmanned air vehicle (UAV) is proposed as a low altitude, station keeping, optical instrumentation platform. The advanced airship design will be derived from parameters developed during the successful Small Aerostat Surveillance System, Low Intensity Target Exploitation (SASS LITE) UAV program. This miniature airship developed by Applied Research Associates, I ...
