This effort will result in the development of a Satellite Telemetry Anomaly Resolution (STAR) tool that automatically: 1) analyzes historical telemetry data, 2) learns expected signal characteristics for specific telemetry signals using prediction networks¿ (an advanced statistical modeling approach) and innovative case based reasoning (CBR) techniques, and 3) applies these models to detect and ...

The topic presented in this proposal has direct application to the development and demonstration of high Mach combined cycle engines. The proposed effort would allow the coupling of a pulse detonation engine (PDE) with a realistic solid fueled gas generator. The specific key technical problems identified in this proposal are the absence of experimental gas generator effluent detonability informat ...

The opportunity addressed in this proposal is an innovative pulse detonation rocket engine (PDRE) which could significantly out-perform current state-of-the-art chemical rocket propulsion systems. The innovation is based in a novel combustion concept developed by Adroit Systems, Inc. (ASI) in the area of airbreathing pulse detonation propulsion. The concept relies on detonation combustion, as op ...

Adroit Systems Inc. (ASI) proposes to develop an innovative concept which reduces the required volume of predetonator mixture in pulse detonation engines (PDEs). The propulsive efficiency of the PDE hinges on the ability to quickly initiate a detonation in a fuel/air mixture. Since most fuel/air mixtures are difficult to detonate, an easily detonable predetonator mixture is typically ...

Aircraft landing gear, and wheels in particular, are subjected to heavy loads during service. Controlled surface compressive stresses help to improve the fatigue life by reducing the probability of crack initiation and propagation from the wheel surface. Manufacturers such as Allied Signal will induce a surface compressive stress by either shot peening or roll burnishing. Acoustic an ...

The proposed research combines an innovative eigenvector method with other electromagnetic techniques to produce a hybrid approach towards solving the EM coupling to satellite cavity problem. The physical structure is divided into an exterior region and one or more interior regions. The exterior region is modeled with method of moments (MOM) and or hybrids of MOM with the uniform theory of diffr ...

A typical Air Force base will produce several thousand gallons per year of used turbine engine lubricants. These lubricants can be collected on site and sold at relatively low cost for other uses (e.g., plasticizer). The potential for contamination of the collected lubricants, particularly with halogenated compounds such as degreasing solvents or turbine fuels, reduces the effectiveness of a previ ...

The Air Force has requirements for site cleanup and environmental compliance related to contaminated groundwater. Remedial operations of water contaminated with volatile organic compounds (VOCs) presently utilize technologies such as air stripping, activated carbon treatment, reverse osmosis, ultrafiltration, and pervaporation. All of these methods require an advancement in monitorin ...

AeroSoft proposes the development of efficient and accurate Computational Fluid Dynamics methods for calculating the airflow characteristics over complex bodies with time-dependent, Reynolds-Averaged, Navier-Stokes equations which have been augmented to allow for dynamic meshes as well as non-equilibrium chemistry and thermodynamics. The dynamic-mesh approach proposed here is based on ...

The trend toward replacement of highly toxic chemicals with less hazardous alternatives has created the demand for replacement of chromate conversion coatings for corrosion protection of aluminum alloys. Aluminum alloys are the predominate structural material used in aircraft because of their high strength-to-weight ratios, affordability and processability. Aluminum is subject to catastrophic fail ...
