The Air Force is seeking new technology that will provide the means to accurately measure and monitor turbine inlet gas temperature in gas turbine engines, particularly in advanced engines operating at very high temperatures (>3,100 degree F). In Phase I of this program, Advanced Fuel Research, Inc. demonstrated that turbine inlet gas temperature can be determined from non-intrusive measurements ...

The proposed multi-spectral IFF beacon will use 40 to 50 % effient high power laser diodes at 863, 1064, and 1550 nm wavelengths. Thermal emitters including diamond-like carbon thin films, photonic crystals, and quantum cascade lasers will be characterized and compared. Finally a model to predict the detection range of IFF beacons will be developed using proprietary emitter power and atmospheric ...

The continuing demand for improving the capabilities of Full Authority Digital Engine Control (FADEC) systems while reducing their size, weight and cooling requirements has led to investigations of alternate architectures and electronic devices for the next generation of advanced propulsion systems. The feasibility of using available Silicon On Insulator (SOI) technology devices that can operate i ...

With the depletion of fossil fuel reserves, hydrogen-based energy is becoming increasingly significant. Production, purification and compression of hydrogen represent key technical challenges. Hydrogen is most commonly produced from steam methane reformers, by gasification or as a refining or chemical system off-gas. All of these production systems require purification and compression steps and ...

The goal of this proposal is to demonstrate the feasibility of new multi-scale models for linking higher order micro-structure descriptions to failure initiation and crack propagation for high cycle fatigue of high strength titanium alloys. This includes new high temperature materials such as the lightweight intermetallic titanium aluminide turbine blades to be used in the lower pressure sections ...

There is currently no satisfactory solutions for real-time, continuous monitoring of are combustion efficiency and emissions. Since emission inventories are the foundation for efficiency controlling pollution's harmful effects, it is important to determine the combustion efficiency as well as the gas compositions and concentrations emitted from the area. In order to implement effective control and ...

We propose a suite of nonlinear image processing algorithms derived from the analysis of the underlying diffusion geometry of a collection of hyperspectral images of interest. These tools enable the comparison of spatio-spectral features of hyperspectral images acquired under different conditions, for the purposes of target detection, change detection and anomaly assessment. This methodology also ...

Residential and commercial air-conditioning consumes over 15% of all electric energy generated in the USA and creates two sources of environmental pollution: 1) the ozone-depletion effect of traditional refrigerants belonging to CFC and HCFC groups and 2) the emission of greenhouse gases connected with the generation of electricity. Both sources are contributing significantly to the global warming ...

This Small Business Technology Transfer Phase I project is proposed to address high temperature superconductor insulation to help improve stability and quench protection. Most importantly stability will be increased so that the power level at which quench occurs is greatly increased. Quench is the rapid, unintended transition from superconducting to normal conducting. It is a consequence of a faul ...

The development of electronic devices that are robust, highly efficient, compact, and powerful with wide operational frequency range is critical for enabling precision effects and full battlespace awareness for the U.S. Air Force. High performance tunable dielectric materials are needed with high dielectric permittivity, low dielectric loss, high dielectric strength, and large nonlinear response ...
