This project is the development of a single crystal underwater acoustic modem transducer for Unmanned Underwater Vehicles (UUV) which is compact in size, operates at low to moderately low center frequencies, in a broad band frequency range to accommodate state-of-the-art binary, FSK and spread spectrum signaling schemes that promote covertness. The device exploits the high coupling coefficient an ...

The FCS (Future Combat Systems), WIN-T (Warfighter Information Network-Tactical), and JTRS (Joint Tactical Radio System) programs have all identified the need for secure and survivable ad hoc wireless tactical networks to support the network centric battlefield environment of the future. To address this need, Architecture Technology Corporation (ATC) will build and demonstrate STAMINA (Survivable ...

This Phase II SBIR project addresses the development of novel solid state Zinc Oxide-based light emitting device. These devices will find widespread application in civilian and military markets. The objective of the Phase II is to develop UV/Blue emitters using the CdZnO/ZnO material system. SVT Associates utilize innovative approaches for material epitaxial growth p-type doping and device design. ...

In self-repairing composites, usually liquid chemicals are contained inside a fiber or bead vessel that is embedded inside the polymer composite matrix or laminate. Damage such as an impact or fatigue microcracking causes the breaking of the vessel, release of internal chemicals into the damage site where they wet the sides of the damage site, react together or with the matrix resin and close or f ...

Maintaining wire integrity of aging aircraft is an immense effort and cost for the military and commercial airlines. The Navy is reported to spend 1.8 million maintenance hours annually trouble shooting and repairing aircraft wiring. The development of an in-situ wire fault location system is critical to the solution to reduce cost, minimize downtime and improve safety. A key component of this sys ...

Integral bladed rotors (IBR) manufacturing is an essential part of gas turbine fabrication for modern fighter aircraft. Stringent dimensional tolerance and surface finish requirements necessitate precision manufacturing and consequently, resulting in increased cost. Our Phase II proposal will demonstrate innovative high speed machining (HSM) technologies the Air Force needs for affordable fabrica ...

The overall goal of our Phase II project is to demonstrate innovative, scalable high-performance machining (HPM) processes the Navy needs for thin-web, large-pocket Ti-6Al-4V firewalls and bulkheads. The anticipated benefits of the program are the ability to fabricate unitized structures resulting in reduced labor costs, part count and improved quality while achieving desired weight requirements a ...

This Small Business Technology Transfer Phase II Program will demonstrate a magnetic field sensor device of high sensitivity using spin-dependent tunnel (SDT) materials. The tunnel materials will be developed with guidance from the state of the art realistic atomistic modeling and aided by state of the art nanostructural characterization techniques of 3-D atom probe and high-resolution transmissio ...

The use of Net-Centric Enterprise Services (NCES) to provide ubiquitous access to information within the Department of Defense presents challenges in both the design and implementation of these systems. The need to provide information to the war-fighter in a timely manner while maintaining the security of the system in challenging environments far exceeds the capabilities of present day enterpris ...

Diesel engines are attractive for military use because of good fuel economy and ability to use JP8-type fuels. However naturally-aspirated (n.a.) diesel engines have low power density, and small diesel engines are not amenable to turbo-charging. To overcome this disadvantage for weight-sensitive applications such as portable generators (gensets), the use of a novel supercharger is proposed. In ...
