NONLINEAR OPTICAL MATERIALS ARE REQUIRED FOR A VARIETY OF POTENTIAL AIR FORCE APPLICATIONS INCLUDING OPTICAL SIGNAL PROCESSING (SWITCHES, MODULATORS, AND GUIDED WAVE DEVICES), AND NEW LASER SOURCES (OPTICAL PARAMETRIC OSCILLATORS AND HARMONIC GENERATORS). HOWEVER, PRESENTLY AVAILABLE MATERIALS ARE UNSATISFACTORY FOR MANY APPLICATIONS DUE TO SMALL NONLINEARITIES, POOR OPTICAL CLARITY, LONG RESPONSE ...

Simulation provides a means of duplicating the operating environment of a topic of interest in a laboratory setting, but the environment itself is rarely the topic of interest. Providing the simulated environment requires access to personnel with expertise in the environment but without expertise in the topic actually to be studied, consuming resources but only providing the means to complete the ...

AN INNOVATIVE INTEGRAL DIELECTRIC HEAT SINK MATERIAL, DIAMOND/CARBON/CARBON COMPOSITE, IS PROPOSED IN THIS PHASE I RESEARCH FOR THE USE IN FUTURE ADVANCED ELECTRONIC DEVICES. CARBONE/CARBONE COMPOSITE HAS A HIGHER THERMAL CONDUCTIVITY AND LOWER DENSITY, AND THEREFORE A HIGHER SPECIFIC THERMAL CONDUCTIVITY, AS COMPARED TO METALS. HOWEVER, CARBON IS ALSO AN ELECTRIC CONDUCTOR. WE PROPOSE TO APPLY DI ...

ADVANCED ENGINE TECHNOLOGY AND HYPERSONIC FLIGHT SPEEDS OF FUTURE MILITARY AIRCRAFTS PLACE INCREASING HEAT LOAD ON JET FUELS. THE INCREASE IN HEAT LOAD PUSH THE OPERATION OF FUELS INTO THEIR SUPERCRITICAL REGIME. THE PERFORMANCE OF FUTURE AIRCRAFT WILL BE SERIOUSLY LIMITED IF FUELS CANNOT BE OPERATED EFFECTIVELY AT SUPERCRITICAL CONDITIONS. THE PRECOMBUSTION CHEMISTRY AND TRANSPORT PROCESSES AT TH ...

For sustained high speed flight (Mach 3-6), recent studies have shown that endothermic fuels are required to cool aircraft systems. Such a cooling system would deliver fuel to the ramburner in varying amounts of liquid and gaseous phases. This project proposes to experimentally investigate and develop an innovative dual-phase fuel injector prototype suitable for crossflow injection in ramburners. ...

To develop an evaluation aid for Hypersonic Technologies, it will be necessary in this effort to achieve three technical objectives. First, a traceability from our national security objectives to the specific regional military objectives and tasks under Defense Planning Guidance Scenarios. This traceability must follow a consistent set of groundrules such as the functional capability requirements ...

This proposal is for the development of innovative lineary motor technology for application to a range of cryocooler systems of interest to DOD, including Stirling cycle, pulse-tube, and Joule- Thomson coolers. Teh VULCAN linear motor concept principle has been proven in hardware applications involving Stirling cycle refrigerators and electrical generators. The VULCAN linear motor offers significa ...
