The proposed research program aims to develop a physics-based identification, modeling and management infrastructure for aeroelastic limit-cycle oscillations. This infrastructure will be built upon high fidelity state-of-the-art theoretical/computational methods as validated and verified by available experimental data bases, and will include (1) rapid flutter boundary determination for a wide ran ...

Applied Optimization, Inc., in working with EWI, Inc., Ohio State University, and Boeing Phantom Works, proposes to demonstrate feasibility of using microstructural models to predict the required processing conditions that can produce nanostructured grain sizes in the thermo-mechanical affected zone in friction stir processing [FSP] of 7075-T6 aluminum. First step will be an FSP trial using the p ...

Crystalplex has developed novel semiconductor nanocrystal technology that can be a platform solution to meet the Army's desire for a light emitting diode (LED) with enhanced output in the deep green region using nanoparticles. This innovation produces an efficient deep green (555-585 nm) nanoparticle emitter capable of sustaining the Army's stated goal of 120 lumens per watt of input power. Crys ...

Development of new generation of integrated FPAs that are both multispectral and polarimetric in the IR window is proposed for the detection and classification of battlespace objects. The use of existing sensor and camera technology, as the baseline, allows for reduced prototype and development time. The integration of both the wavelength and polarization selective elements within the FPA will p ...

This project will develop an open architecture "component based" surgical information system for the military health care system. The system will build upon our current commercial data collection system that is FDA cleared and the result of several prior SBIR awards. We will add components to complete the solicitation requirements. To address a broader and more durable goal we will focus on deve ...

The objective of this research is to improve the effectiveness of scalable wireless mesh networks in bulk data transfers and multimedia streaming. Several studies have shown that the performance of 802.11-based mesh networks degrades rapidly as the number of hops increases. Mesh networks based on newer technologies, such as WiMAX, could alleviate these problems by using innovative protocols which ...

A unified project comprising basic research and technology development is proposed to address all important issues critical to the design, fabrication, testing, and implementation of an integrated micro thruster and power-generation system. This program will fully utilize the state-of-art and projected technologies in the areas of energy conversion and micro fabrication. A novel design of the ig ...

This STTR Phase I program is focused on evaluating both fine-grained alpha-alumina and polycrystalline YAG materials for utilization as visible and UV-transparent windows in advanced propulsion systems. These applications require improved window materials that provide for higher temperatures and pressures, along with low energy losses and lower weight; both fine grained alumina and ceramic YAG ha ...

The proposed work addresses the problem of determining whether a given small unmanned ground vehicle (SUGV) can traverse a given terrain, when the state of both the SUGV and the terrain are not known exactly. In our previous work, we developed computational models of an Army-relevant tracked SUGV-the PackBot-traversing terrain. Using SolidWorks, we built three-dimensional solid models of the veh ...

ABSTRACT: Modern gas-turbine engines designs for the next-generation warfighter need to reduce exhaust gas temperatures to reduce effective thermal footprint thereby improving the mission capability. In such situations, high-altitude engine operation is often limited by the overall combustion efficiency, lean flame blow out (LBO) limit, and combustion instabilities that results in narrower opera ...
