Petroleum products from fueling and maintenance facilities are common pollutants in surface and groundwater. Most oil/water separators currently in use are coalescing plate interceptor (CPI) units made up of closely-spaced plastic plates submerged in the waste stream. Microscopic oil droplets coalesce on the surfaces of the plates, then collect and rise to the water surface in the plate chamber. T ...

This proposal is in response to the topic objective to apply and control the application of multilayer seal coatings on all surfaces of integral fuel tanks. An alternate polymer deposition method is proposed to meet the objective without the need for expensive, complex sensors and controls. A polymer coating, composed of Teflon and a second resin, is to be deposited electrochemically from aqueous ...

Fasteners are used extensively on both military and civilian aircraft structures. Stress concentrations introduced by fastener holes, the intimate contact between these materials dissimilar in nature and/or stiffness and the inherent load transfer demands placed on the fasteners themselves can all lead to problems in service. One of the critical parameters which determines the longevity of a joint ...

Studies have shown that halocarbon refrigerants (CFCs and HCFCs) damage the earth's ozone layer. To halt the damage, regulations (i.e., U.S. Clean Air Act of 1990) were created that prohibit emission of these refrigerants into the atmosphere. These regulations have created a need for refrigerant recovery and recycle systems. However, units avilable today are limited in their capabilities. Most are ...

ORBITEC proposes to develop a means to produce and utilize cyrogenic solid-based hydrogen fuels in a combustion chamber. Controlled freezing from the gaseous phase at or below the triple point assures uniform solid phase formation directly from gaseous phase. The vapor pressure of hydrogen is negligible at temperatures below 10K (< 0.1psi), and sublimation rates would be negligibly slow. We propos ...

CRUSH SENSORS AND PROBES USED IN INEXPENSIVE MISSILES AS CONTACT DEVICES ARE EASILY DAMAGED BY HANDLING OR ANTI-MISSILE DEFENSES. PIEZOELECTRIC ACCELEROMETER CONTACT FUZES WITH FIXED THRESHOLDS HAVE TROUBLE DETECTING A "SOFT" IMPACT WITH AN AIRCRAFT-S ALUMINUM SKIN IN THE PRESENCE OF ACCELERATION NOISE. AN ADAPTIVE CONTACT FUZE IS NEEDED TOSENSE SUCH SOFT IMPACTS IN THE PRESENCE OF ROCKET MOTOR, W ...
