This effort explores and assesses the options available for refractory composite leading edges cooled by embedded metallic heat pipes. Currently, the heat pipe cooled leading edges (HPCLE's) being investigated are fabricated primarily from refractory superalloys. However, even the best superalloys have a temperature limit of ~2400°F, which places substantial limitations on the possible geometry ...

This Phase II proposal outlines an ambitious research and development effort the objectives of which are to provide a high-voltage pulsed power generator that is compact, portable, reliable, exhibits a fast rise or fall time, and is capable of being command fired at a high pulse repetition rate (PRR) with low jitter. Another objective of this effort is to design and realize a feedback control sys ...

This Phase I SBIR proposal outlines an effort that will advance the state of the art in high repetition rate solid state pulse generators. For this effort, we have assembled a team of key people with direct experience in high peak power solid state pulse generator design, measurement and characterization of fast transient waveforms, and semiconductor interconnection and packaging techniques. The ...

In this proposal RMA describes two fresh new approaches, based on the Characteristic Basis Function Method (CBFM), as a way to handle the radiation and scattering problems of interest in this project. We offer two versions of the CBFM, one for the frequency and the other for the time domain, based on the MoM and FDTD formulations. In contrast to the Fast Multipole Method (FMM), the CBMOM solves la ...

We propose to continue our Phase I efforts by demonstrating the class of hybrid Kalman particle filters (HKPF) for tracking ground targets on road in Phase II. In the proposed formulation, the road network is represented with one-dimensional (1D) models. This 1D modeling simplifies the target kinematics considerably and reduces the size of the target state space by up to ½, which directly transla ...

We propose to continue our Phase I efforts by demonstrating the full potential of the nonlinear filters for GPS OCS precision estimation in Phase II. The demonstration will be carried out in a more realistic computer simulated software environment. We also plan to use the recommended architecture and the validated software to process real GPS data for demonstration. The Phase I study has showed pe ...

78208S Current processes to produce liquid fuels by direct hydrogenation of coal are not cost-effective. Therefore, improved process chemistry and/or reactor design will be required to produce transportation fuels from coal at prices that are competitive with currently used fuels. This project will develop a coal liquefaction process that uses a nanoscale active catalyst precursor in a plug flo ...

79788S The DOE-sponsored Solid State Energy Conversion Alliance (SECA) seeks to develop commercially-viable 3 to 10 kW Solid Oxide Fuel Cell (SOFC) systems by the year 2010. One of the weak links in this system is the heat exchanger, which typically consumes more than 30% of the installed cost ($ 400/kW) and fails before the 40,000 hour design lifetime goal. While traditional ceramic materials ...

This project will modify TerraTools(R), our COTS simulation database generation software, to generate visual databases with attribution containing relevant thermal and spectral parameters for each object or polygon in the scene. The output visual database will then be fed into existing sensor simulation systems, using a TerraSim API, to support the construction of highly-detailed and accurate vis ...

Touchstone Research Laboratory proposes to investigate use of a CFOAM core in a sandwich panel configuration for an all-composite, low-cost, lightweight, EMI-shielded Rigid Wall Relocatable Structure (RWRS). Carbon foam offers excellent EMI shielding properties due to its high electrical conductivity. An all-composite shelter would eliminate metallic components that are susceptible to environmen ...
