Current research initiataives, including DoD IHPTET and HyTech, DOE ATS, and commercial development, are agressively pursuing significant improvements in combustor performance Optimization typically results in operating regimes for which combustionstability is difficult to maintain. This proposed program continues the novel combustion control and optimization concepts with flexible dual-use appl ...

The U.S. Navy designed high-power active sonars like the Low Frequency Active (LFA) system to counter quiet submarines. High-power transmissions from mid- and low-frequency sonars are known to cause trauma for human divers. To comply with the MarineMammal Protection Act and the LFA Environmental Impact Statement (EIS), the U.S. Navy must effectively reduce active sonar transmissions to benign lev ...

This proposal is on the demonstration of a portable, thermally self-sustaining, Solid Oxide Fuel Cell (SOFC)-based power module, delivering 25 W at ~70% efficiency, continuous power operating on liquid hydrocarbon fuels, with energy density > 1300 Wh/liter(>2000 Wh/kg. for a 72hr. operation), including fuel canister. SOFC stack, operating at 550oC, is based on novel, anode-supported fuel cells wit ...

Frontier Technology, Inc. (FTI) and University of Florida (UF) propose to validate and demonstrate designs for biomimetic camouflage systems (

Phase I feasibility research will be based on developing novel organic/inorganic hybrid, inhibitor modified or reacted silane based corrosion inhibitor systems that will enhance corrosion suppression capability of existing organic/inorganic hybridcorrosion inhibition systems by incorporating novel inhibitor modified silanessuch as novel silanes modified with imidizoles as a novel corrosion inhibi ...

Crested multi-layer tunnel barriers have been proposed, which offer a revolutionary solution to overcome density to speed trade-offs characteristic of present data storage technologies. Practical implementation of the proposed technology will involve useof thin film materials which are readily manufacturable and CMOS-compatible. A critical need exists for experimental verification of the theoret ...

Our objective is to construct a new solution procedure for high frequency electromagnetic scattering and propagation problems, and to initiate building and validation of a new 3D high frequency Maxwell equations solver. The proposed method will constitutean extension of a recent asymptotic formulation of the electromagnetic integral equations for high frequency scatttering and radiation problem. ...

The present text proposes development of a new approach for the numerical evaluation of high-frequency electromagnetic scattering for structures of interest to DoD. This approach, which relies on high-order high-frequency integral asymptotics, is entirelyrigorous: it should account fully for all scatterer complexities and all electromagnetic effects - including multiple-scattering, diffraction, ca ...

This effort will investigate a recent breakthrough in damping materials developed under AFOSR sponsorship at UCLA for potential application to launch vehicle and spacecraft component vibration mitigation. CSA believes that the proposed effort is unique inthat it offers, for the first time, a practical high performance passive solution to the vibration suppression needs of several Air Force applica ...

We shall use recently developed numerical technology to compute detonation phenomena accurately,deal with mixed phase flow, high strain rate solid mechanics and complex geometry. These new techniques, developed largely by the personnel involved, includethe level set method, ghost fluid method, ENO and WENO shock capturing schemes, solid fluid interaction methodology and the fast closest point tran ...
