Functionally smart materials, which have to ability to perform both sensing and actuating operations, are being developed to perform many aircraft type of control events. Smart materials, fabricated suing "continuous ferroelectric fibers," are being consider for full flight control of subsonic missiles, as the servoactuator system, specifically, and for active aerodynamic surface cont ...

The goal of this program is to design and fabricate selected liquid rocket engine combustion components. This goal will be accomplished by developing a low-cost, near net-shape technology for fabrication and rapid densification of ablation and oxidation-resistant LRE components for a wide variety of Air Force missions. The material which will be used for this purpose is zirconium diboride/boron ...

AeroMed Software, L.L.C., proposes to develop an interactive virtual environment simulator for vertical aircraft signal training. The proposed system is intended to provide Landing Signal Enlisted (LSE) trainees with a dynamic training device similar to the operational flight trainers used by aviators. Recent advances in data acquisition, signal processing and graphics software, computer process ...

Investment castings have well served both the military and commercial markets in such areas as waveguides and splitters for microwave applications, and for connectors, housings, heat sinks and mechanical parts for electronics, optical, instrumentation, and medical devices. Tomorrow's higher RF millimeter wave and communications electronics products, and more compact optical, instrumentation and m ...

We propose a new epitaxial growth technology for low-defect SiC substrates based on metallic solution growth of SiC on silicon and SiC wafers. A significant feature of the our approach is the use of epitaxial lateral overgrowth for "defect filtering." In the Phase I proposal, we present arguments that the proposed technology will lead to SiC material of unprecedented quality with respect to defect ...

There is much need for lasers with emission wavelengths in the mid-infrared (2 to 5 microns) for applications that include molecular spectroscopy, environmental and atmospheric trace gas analysis, long haul fiber communications, laser surgery, and atmospheric free-space laser transmission. The Lebedev Physical Institute in Moscow has reported double heterostructure GaInAsSb/GaAlAsSb lasers emittin ...

AstroPower proposes to develop a new high voltage solar cell for photovoltaic linear concentrator arrays based on our thin GaAs solar cell and epitaxial lateral overgrowth technologies and applying lateral segment interconnection techniques. This solar cell design has several advantages which make it ideal for space concentrator systems. These are high system voltage (10 to 500 volts per cell), re ...
