We propose synergistically implementing two emerging ballistic materials,aluminum foams and 3-D woven polymeric composites, in theconstruction of lightweight armor with ceramic facing. In the recentballistic studies both materials have separately demonstrated improvementsin ceramic-faced armor. 3-D woven FRP enables to reduce dynamic deflection,localize damage and increase multiple hit capabilit ...

Higher inlet temperatures for turbine engines will provide significant benefits in fuel efficiency and performance for both military and commercial air vehicles. To accomplish this goal, new generation thermal barrier coatings (TBCs) with superiorreliability and durability will be needed. The currently-used zirconia-based TBCs do not adequately meet thermal conductivity requirements and they suf ...

The objective in this exploratory development is to design, fabricate and test a dual-mode radome for a high speed missile application. Performance, cost and ease of manufacturing will be emphasized. Radome models will be produced to be as close toflight hardware as practical. The use of an insert to provide performance enhancements will be incorporated into the design.

We propose to develop an efficient heat rejection unit for cryogenic cooling with ultra low parasitic thermal, mechanical, and electromagnetic noise for cooling filters and sensors at HTS conditions. The proposed device will incorporate active micro-scaleheat transfer surfaces, pump(s), and temperature sensors in a single package that will be directly attached to the heat source. EHD micro pumpi ...

The objective of this Phase II program is to achieve a commercial solar blind AlxGa1-xN based p-i-n ultraviolet (UV) photodetector product, with high solar blindness, high external quantum efficiency and low dark currents. The Phase II work will buildupon the results obtained from the completed Phase I project, which showed the feasibility of the proposed lateral epitaxial overgrowth approach to ...

The phase II proposed effort continues our studies initiated under our phase I work entitled Nitride Semiconductor Substrates. Having demonstrated the ability to produce large area (100-mm) GaN-on-silicon, Nitronex now proposes to advance the technologytowards fabrication and commercialization of X-band High IP3 AlGaN/GaN HEMT Low Noise Amplifiers (LNAs) on silicon. Our goals are to demonstrate ...

A portable hydrogen source for proton exchange membrane fuel cells (PEMFCs) isproposed. The design utilizes both an exothermic reaction between ammonia (NH3)and aluminum hydride (AlH3) and ammonia decomposition. This process isinitiated by catalytic decomposition of a small amount of NH3 at about 450 ¿Ctemperature and is subsequently self-sustained to provide hydrogen to the fuelcell on deman ...
