The innovation presented in this proposal involves the use of a liquid melt thermal spray process for cost effective rapid prototyping of near-net shape tooling for the lay up of advanced composite materials. The process uses a focused beam of charged liquid droplets to form tooling directly from three-dimensional computer generated drawings eliminating traditional steps associated with fabricatio ...

Space-based systems must dissipate tens to hundreds of watts for communications, housekeeping, etc. TRA proposes a novel thermal strap which would allow efficient energy conduction from heat sources to the structure of the spacecraft or to heat dissipation units. The thermal strap would utilize high thermal conductivity graphite fibers. Techniques for joining the fibers to end connectors will be i ...

One of the limiting factors in the operation of MEMS is energy transmission and storage. It is often necessary to transmit energy for a MEMS from some external source into the circuit, thereby suffering power losses which can be significant. The reduction of the power losses is therefore a desirable goal. The purpose of this work is to develop and build microscopic batteries (0.0001 cm2) which can ...

The proposed process will provide the capability to deposit metal coatings onto heat sensitive composite substrates. The process eliminates problems associated with thermal spray technologies, including oxidation, contamination and overheating of the coating and substrate materials. This process enables dense, adherent coatings to be applied to low temperature composite materials for wear, corrosi ...

We propose to develop intermediate to high power (.1 to 4 W), frequency- stable diode lasers with high modulation capability and long life. Our approach can provide fixed-frequency radiation sources for 1 pace-based ballistic missile defense applications. To demonstrate the technology we will develop a compact, lightweight, relatively inexpensive, proprietary external-cavity-stabilized diode laser ...

A Phase I research program is proposed with two primary technical objectives that are critical to the development of real optical memory devices based on solid state materials. The first objective will be to characterize striae in optical memory materials and subsequently grow improved reduced striae crystals. Striae is currently limiting the performance of technololgies based on the ...

This project proposes to exploit the Giant Magnetostriction of Terfenol-D, along with the properties of piezoelectric ceramics to develop a new class of electric voltage transformer. The Magnetostrictive Piezoelectric Charge Pump (MPCP), when perfected, will provide a new option for the generation of high-voltage electricity. MPCP devices can be built in a wide range of configurations. The primary ...
