The objective of this effort is to demonstrate a prototype advanced diagnostic system for the T800 turboshaft engine using a hybrid polynomial network and production-rule expert system. The resulting system will demonstrate the feasibility of developing a revolutionary diagnostic capability which can model the engine at a system level, detect failures before they become signficant isolate faults, ...

Adroit Systems, Inc. proposes to develop a hand-held , autonomous Satellite Location and Point System (SLAPS). The system will store communication satellites' ephemeris data to calculate and display visibility windows. SLAPS also will use this data to calculate the azimuth and elevation angle to the communication satellite of interest. The system will use interferometry of Global Positioning Syste ...

Kinetic energy penetrators are currently relied upon as a way to defeat enemy armor. Historically these penetrators have been composed of unanium or tungsten based alloys due to their high densities. In addition to density, the deformation behavior of the alloy determines it's performance. A penetrator whose tip mushrooms or fractures on impact is less effective than a penetrator that retains it's ...

A number of advanced fiber-reinforced organic matrix composites employed in a variety of Army systems are exposed to environmental weathering and/or in-service loading. This may induce chemical, physical, and mechanical changes in the composite material, and ultimately lead to component failure. This proposal will develop a fiber optic based Fourier transform Raman (FT-Raman) spectrometer for the ...

See Charles River Analytic comment. It applies here also.

The use of high-temperature laser densification/annealing techniques for enhancing materials surface characteristics has opened new opportunities in material/laser-process diagnostic instrumentation. Important issues in fabrication of reproducible refractory ceramic coating film lies in understanding of the interrelationship between processing parameters and surface properties. To respond to this ...

The new aerospace materials are finding applications in the design of military armor vehicles. However, the effect on ride quality, fire control, and internal structural loads due to the increased flexibility of these new vehicles must be ascertained by dynamic analysis. The size of models required to simulate these flexible body effect can be prohibitive from both cost and time perspective. There ...

This receiver sets forth a plan to utilize commercial GPS receivers for real time ionospheric prediction at a remote location. The project will demonstrate the feasibility of using TEC measurements and evaluate the accuracy and applicability of these measurements for improvements in HF propagation. For this we assess the predictability of the slab thickness parameter T towards solar and geophysica ...

EASE (Electrically Adaptive Suspension Element) is comprised of three major sub-systems, these being the electromagnetic Coaxial linear (EMCL) actuator, the Adaptive Feedback Network, and the Thermal Management System. The EMCL actuator is designed for use as the active suspension element of a combat vehicle. The EMCL actuator is particularly suited to this adaptive architecture because the actuat ...
