"Three-dimensional textile reinforcement architectures with straight in-plane fibers and optimized through thickness fiber content are considered as efficient solutions for the next generation of light weight, damage tolerant, high strength compositesallowing for cost-effective manufacturing solutions. The 3-D weaving process is gentle to the fibers, thus making automated fiber optic sensor insert ...

"We propose to develop a new technique for imaging underground facilities based on the passive monitoring of acoustic emissions from both stationary and moving equipment within such facilities. It is well known that all mechanical devices, such as motors,gears, etc, emit acoustic signals. It is possible to identify an acoustic source based on its noise spectrum. In addition, by monitoring the acou ...

"It has been shown theoretically and experimentally, that one-dimensional photonic bandgap (1DPBG) structures enhance nonlinear effects for one to three orders of magnitude. By exploiting these effects, one can achieve efficient frequency conversion (secondand third harmonic generation, and parametric) in materials with modest nonlinear optical properties and in structures with a total path length ...

"After 4 years of basic research, MicroPhase Coatings, Inc. was awarded a Phase I SBIR contract to develop an "ice-phobic" coating for B-2 bomber engine inlets. The coating is an epoxy-silicate base with additives of silicone and melting point depressants.It is hard, durable, slick, hydrophobic, and ice-phobic. The Phase I effort was completed in October 2001 and established technical feasibility. ...

Spatial disorientation is a significant problem in military aviation that has resulted in loss of life and aircraft. Creare is developing a Disorientation Analysis and Prediction System for use in pilot training, accident investigation, spatialdisorientation research, and ultimately as a cockpit-based warning system. The system is capable of determining whether or not the pilot is disoriented, m ...

The excited or dissociated gaseous species created in non-thermal glow discharge plasmas are effective agents for killing or neutralizing certain biological or chemical warfare agents. For decontaminating sensitive equipment or personnel, the effluentfrom such plasmas must be near room temperature to avoid harming the equipment or persons being cleaned and to prevent unintentional dispersal of th ...

"Military and civilian experience has shown that long-duration assignments present increased risk of performance failures as the mission progresses. This is due to interruption of normal sleep cycles and to the psychological pressures of the living andworking environment. The overall objective of this project is twofold: (1) to ensure the safety and effectiveness of friendly military personnel, ...

"Advanced space-borne infrared sensor technology requires cooling at temperatures near 10 K. Cooling loads for these detectors will range from 0.25 to 1.0 W. The satellites carrying these sensors also have additional cooling loads at differenttemperatures. A multistage cooler capable of cooling multiple loads will offer large potential gains in system efficiency and weight. Turbomachine-based, ...

"Creare proposes to design, fabricate, and test a system that will simultaneously protect personnel working in extremely high noise environments and enhance voice communications. Current Air Force ground crews are forced to work in close proximity toaircraft engines that produce in excess of 150 db of noise, which can result in noise-induced hearing loss after brief exposures without sufficient h ...
