Next-generation turbulent combustion models must enable accurate prediction of lean blow-out and flashback for complex geometries, fuels and operating conditions relevant to the Air Force. Improved models are needed to better predict kinetically and hydr...

The ability of Large-eddy simulation (LES) techniques to accurately predict combustion instabilities and the onset of lean blow-out is not yet firmly established, especially in realistic operating conditions. A number of modeling choices play an importan...

GrammaTech proposes WARP, a tool for Weaving Application-specific Runtime Policies into embedded systems binaries.Perimeter defenses such as firewalls or network filters provide insufficient security and generic inline defenses such as control flow or ...

In this Air Force Phase I STTR program, MATECH proposes to demonstrate novel pre-ceramic polymer systems complimenting the development of Ultra High Temperature (UHT), high ceramic yield, refractory ceramic matrix composites (CMCs). A leader in developme...

This proposal describes the development of a process to synthesize low defect Ge1-xSnx and SiyGe1-x-ySnx layers on silicon and silicon-on-insulator (SOI) substrates through low thermal budget excimer laser and rapid thermal annealing/crystallization for ...

A diagnostic is proposed for obtaining instantaneous three-dimensional volumetric distributions of density in a flow field at velocities ranging from subsonic to supersonic. Two variants of laser-based Rayleigh scattering will be investigated, each of wh...

Future gas turbine propulsion designs, in addition to incorporating variable geometrical engine features, will require controlling and integrating large power generation/extraction, as well as, managing thermal limits of the components. The engine contro...

allowing the sensitive RF front-end to be located away from the now more compact phased array antenna. We are proposing a rugged photonic integrated spatial division multiplexing RF link for phased array system with low cost, size, weight and power cons...

We propose to develop a 3D tomographic background-orientated Schlieren measurement technique, including hardware setup and post-processing software to produce 3D visualization of compressible flow features in subsonic, transonic, and supersonic wind tunn...

Next-generation intelligent engines will operate at higher temperatures for increased efficiency and will migrate from centralized to distributed control. There is critical need for sensors for operation at ultra-high temperatures (3000F). Conven...
