Acadia Optronics, LLC, in partnership with the University of Kansas, proposes to develop a hybrid reconfigurable Software-Defined-Radio (SDR) architecture in which plug-in, front-end, rf modules interface to powerful, reconfigurable processing hardware and software through high-throughput interconnects. The complexity of the plug-in modules may range from simple antennas, to complete communication ...

The present proposal is focused on developing novel methods to counteract excessive heat build-up in underwater sonar projectors. Building on over 25 years of experience in the design of Navy sonar devices and thermal management applied to high power density transducers and smart material actuators, Active Signal Technologies and Alfred University will model several readily implemented passive an ...

Software Defined Radio (SDR) technology and solutions are proven and capable. However, the cost of the systems limits their immediate use outside of military applications. Beside the cost of the SDR systems, it has been difficult to develop SDR concepts and prototypes on platforms that have clear migration paths to become commercial products. EFJI and Virginia Tech propose to develop a versati ...

Large format, low cost, reliable and high performance infrared focal plane arrays are essential for the Army’s Third Generation IR Imaging Technology. HgCdTe (MCT) detectors fabricated on silicon substrates are an attractive alternative generating considerable interest. State of the art technology produces CdTe buffer and MCT epitaxial layers with dislocation densities of 5x105 and 106-107/cm2 r ...

CompuTherm, LLC in collaboration with Oak Ridge National Laboratory proposes to develop a modeling tool that can be used to understand the effect of Ti, Zr, and Hf addition on the improvement of ductility of the (Mo) phase in the Mo-Si-B system. The tool will be developed by integrating thermodynamic modeling with mechanical testing. Thermodynamic descriptions of the Mo-Si-B-X (X=Ti, Zr, Hf) syste ...

Surface ship generated bubbles are a major signature contributor. For advanced ships such as the LCS, waterjet propulsion adds another source of air entrainment through the waterjet free surface interactions. In littoral warfare, such wakes provide an opportunity to wake homing torpedoes due to large acoustic cross-section of bubbles. While there is research on breaking waves bubbles, little is ...

This Small Business Technology Transfer Program is aimed at the development of an innovative method and procedure for depositing corrosion-resistant material to aircraft components as an alternative to aluminum cladding approaches. We plan to use environmentally compliant amorphous metal coatings from the Al-Co-Ce and similar alloy families that have recently been developed at the University of Vi ...

In Phase I, technical and commercial feasibility was demonstrated for the application of friction stir processing (FSP) following by superplastic forming (SPF) of a 5083 aluminum alloy, and for FSP following by room temperature bending. An application showing significant promise for FSP followed by SPF is an aluminum water tight door. The use of FSP followed by SPF enables a significant part co ...

Friction Stir Welding (FSW) has been demonstrated to provide significant benefit for Naval applications. However, its use has been limited to fabrication of panels, because no portable multi-axis FSW solution exists. If FSW could be used for in situ fabrication of complex assemblies, significant further benefits could be realized, including cost reduction and improved quality (significantly less ...

Friction Stir Processing (FSP) has been demonstrated to generate refined microstructures, resulting in improved material properties. This has several areas of application. First, FSP can enhance the formability of the particular alloy of interest. This is especially important for the superplastic forming process, where the use of FSP can be used to create superplastic behavior at high strain r ...
