This SBIR effort proposes to develop tools that enable a capability in tamper proof source code. The proposed methods will protect against several modes of attack including malicious programmers, source code viruses, and system worms. The tools and techniques proposed are based on the fundamental logical structure of the application under protection and offer dynamic monitor and control of runtim ...

Strength and durability of commonly used bonded and bolted composite-to-composite and composite-to-metal structural joints suffer from sharp geometry variations, mismatch of elastic moduli, Poisson's ratios, coefficients of thermal expansion and thermal conductivity of the adherends, altogether causing high stress concentration and premature joint failure. The proposed work introduces several nove ...

The Air Force Research Laboratory (AFRL), Military Satellite Communication (MILSATCOM), and National Aeronautics and Space Administration (NASA) have a current and future need for advanced commercially available inherently radhard primitive cell libraries to support new designs for satellites and other spacecraft. American Semiconductor Inc. proposes the use of double gated Flexfet technology for ...

The proposed research will develop a non-equilibrium plasma source for deposition of thin films on refractory materials at temperatures less then 600K. The developed source will also have the flexibility to surface treat thermally sensitive substrates without damage. Our existing non-equilibrium atmospheric plasma source will be optimized for depositing amorphous SiC and ZrO2 thermal barrier mat ...

Significant recent research has shown that breath biomarkers are excellent indicators of oxidative stress caused by conditions ranging from radiation exposure to COPD. Current techniques for collection, concentration, and analysis of exhaled breath do not support real-time analysis, or require complex and bulky equipment. Streamline Automation, LLC will develop a portable Breath BioDetector in p ...

Combustion Large Eddy Simulation (LES) is a very promising approach for resolving acoustics in turbulent-reacting flows. CFD Research Corporation (CFDRC) has successfully developed and validated state-of-the-art Combustion LES software (CFD-ACE+) to analyze gas turbine acoustics, using unstructured grids with second-order temporal and spatial differencing. Still, unstructured LES has not yet matur ...

CFDRC proposes to develop a comprehensive, high fidelity commercial quality simulation tool for modeling the Cold Hearth Melting (CHM) processing of Titanium alloys. The code will accurately predict the transient temperature distribution, flow patterns, skull shape, species evaporation, and particle fates in the hearth region for a given set of dynamic operating conditions. The foundation for this ...

CFD Research has demonstrated improved atomization, mixing control and lower emissions using an electrostatic charged air-blast fuel injector retrofitable within the RR501-K U.S. Navy Shipboard gas turbine engine. Without altering current configurations electrostatic fuel injection and combustion charging could further reduce emissions, improve stability, enhance ignition and/or tailor thermal pr ...

Hydrocarbon combustion chemical kinetics are extremely complex, with detailed reaction mechanisms typically consist of thousands of reaction steps and hundreds of species. However, most reacting flow CFD simulations can only afford reduced global mechanisms with standard Arrhenius rates. Unfortunately, global mechanisms are typically only valid over limited operating ranges and cannot account fo ...

Modern aerospace vehicles operate at high angles of attack and perform aggressive maneuvers, which lead to flow separation, turbulence, high dynamic loads problems such as buffet and flutter. Accurate CFD model-based simulation of these problems requires careful attention to fluid-grid movement, fluid-structure interfacing and turbulence. CFDRC proposes to develop and validate a novel structural-b ...
