The proposed program is to develop the use of aqueous biopolymers for the solid freeform fabrication of ceramic components. It will be a collaborative effort between ACR and Battelle PNL. PNL has expertise in colloidal ceramic processing and experience on utilizing biopolymers in ceramic slurries. ACR has already developed extensive software and hardware capability for solid freeform fabricatio ...

The goal of this program is to develop a low cost, flexible manufacturing method for the production of Cf reinforced composites for ablation-resistant propulsion components for Theater Missile Defense (TMD) concepts. The matrix material selected for demonstration of the technology will be HfC, a material which has demonstrated good oxidation and ablation resistance at elevated temperatures.

Standard U.S. Navy fiber optic assemblies require that the fiber be bonded to the connector using an adhesive that is labor intensive and heat controlled (MIL-A-24792). Advanced Material Systems (AMS) proposes a study that could solve this problem through the development of an adhesive system that would cure at room temperature in less that 3 minutes and yet meet all of the in-service req ...

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 ...

1The most important reason for reduction and subsequent elimiantion of cadmuim coating in fasteners is the high potential health hazard. Industry is eliminating this metal from usage where ever possible. A family of zinc based alloys has shown favor for replacement. Binary systems with several other elemental additions have been investigated by workers in the plating field and found to be credible ...

Anholt Technologies proposes to develop a low cost replacement aircraft Idoor. Preliminary analysis indicates Anholt Technologies' design, using Cpultruded stiffeners, flat panels and advanced adhesion techniques Jpossesses the required structural strength at a significantly reduced end Iitem cost. Anholt Technologies proposes to design, fabricate and test a Frepresentative stiffened structu ...

GaN high electron mobility transistors or HEMTs are proposed for use as high temperature electronic devices. HEMTs are excellent for both power and low noise amplification since they posses a high carrier concentration and an enhanced carrier mobility. GaN has a large bandgap of 3.2 a, which gives it a greater breakdown voltage and a higher saturated electron velocity than GaAs. GaN, in addition, ...

We propose a six month Phase I research program aimed at developing compliant substrates for the epitaxy of GaN and AlGaN films. We present two alternate approaches one with silicon and the other with GaAs as the starting substrate material and a unique multilayer structure to be deposited using low pressure MOCVD. We propose to investigate an approach based on the use of SIMOX substrates. These c ...

1 New concepts in optical computing and optical interconnects require hardware developments of generic, compact, multi-element LED source array. A two dementional array of individually-addressable Light-emitting Diode optical emitters will be developed. An innovative CVD/LPE heteropitaxy technique will be employed for the monolithic integration of high-speed-surface-emitting AlGaAs/GaAs LEDs on si ...
