The design of future Micro Air Vehicles (MAVs) requires detailed understanding of unsteady flows around flexible lifting surfaces with strong interactions between separation and transition at low Reynolds numbers. Since flexure often involves large deformations exceeding the Kolmogorov scale by orders-of-magnitude, methods employing moving and deforming computational grids may require excessive re ...

Nanoscale infrared detectors are emerging as a potentially powerful alternative to traditional infrared detector technologies. The University of New Mexico has developed dots in a double well (DDWELL) quantum dot infrared photodetectors which have a spectral responsivity that can be tuned by controlling the bias voltage applied. In this Phase II effort, Polaris Sensor and UNM would fabricate a g ...

ABSTRACT:nou Systems proposes an innovative analysis and test methodology for testing space-based high-resolution wide field-of-view (WFOV) focal plane arrays (FPAs). Current space sensor test facilities are incapable of fully testing state-of-the-art high-resolution WFOV sensors without infrastructure modifications. The test methodology described in this proposal focuses on testing only a subset ...

Our objective is to develop advanced mediator architectures for efficient electron transfer in enzymatic fuel cells (EFCs) for low power systems. The proposed EFC will leverage ongoing research at both CFDRC and Michigan State University to provide a fully-integrated lightweight, low-cost, manufacturable, and renewable power supply, for various military and civilian applications. EFC systems offer ...

We propose to develop a space based radiation hardened GPS transmit antenna capable of forming spot beams to enhance the GPS signal on the ground by greater than 5 dB. It is expected that our transverse compound hybrid antenna will provide as much as 30 dB gain over a hemispherical antenna allowing enhanced signals over specific areas as large as 500 km. A tradeoff between spot size and signal g ...

ABSTRACT: The overall goal of the proposed effort is to develop and demonstrate a general-purpose, fast, and reliable management and learning software tool for analyzing massive data sets generated by dynamic multi-disciplinary simulation. In Phase I, key technology elements were developed and proof-of-principle was successfully demonstrated. Data management software encapsulating salient feature ...

Modern combustion systems such as liquid rocket engines and gas turbines are characterized by high operating pressures and temperatures due to increased power-density. Thermal radiation has significant impact on both heat fluxes at the wall and on physical phenomena controlling the combustion process at these conditions. Coupling between radiation, turbulence and chemistry can have a large effect ...

ABSTRACT:Modern combustion systems such as gas-turbine combustors and rocket engines are characterized by high operating pressures and temperatures due to increased power density. Thermal radiation has significant impact on both, the heat fluxes at the wall and physical phenomena controlling the combustion process.

In the proposed SBIR project, CFDRC will develop an efficient, high-fidelity computational tool to simulate compaction wave propagation and the ensuing multi-physics phenomena in heterogeneous explosives (HEs), including the effects of shock wave on external targets. Physics that will be accurately modeled include: (1) Resolution of subgrain-size hot spots; (2) Granular deformation and packing du ...

Protein manufacturing is of paramount importance to chemical and biological defense applications. Existing protein purification methods primarily rely on synthetic-resin based chromatography, which is time-consuming, labor-intensive, expensive, and consequently, ill-suited for developing rapid countermeasures to chemical and biological threats. To overcome these limitations, the overall goal of th ...
