Carbon seals generlly used for bearing compartments will incrasingly become unsuitable for future gas turbine engines with higher buffer air temperatures, higher pressur and rotor surface speeds.Phase I effort will focus on a synergistic approach including advanced materials and design.Three materials including a (Ti,Mo)(C,N) cermet, B-C composite and a current high temperature grade carbon MAT-12 ...

Many technical challenges will need to be surmounted to create practical cybercraft: assurance, control, rules of engagement, representation and discovery of the target environment, among others. However a serious challenge lurks behind all of these: scaling solutions to fleets of up to a million craft. New approaches are needed to deploy and control the craft at this scale. Failure to come to gr ...

With improvements in high performance military jet aircraft engines and the increase in complexity of the exhaust systems the noise produced has become problematic. Reducing these noise levels, while maintaining overall system performance, has become the driving issue in new nozzle designs. This proposal will focus on nozzle designs of practical application that can be implemented on current high ...

Due to the phasing out of TNT usage in explosives due to safety and environmental concerns, insensitive explosives utilizing wax binders instead of TNT have gradually replaced TNT in bombs and other explosive shells. The wax material that has been the most utilized in this application has been carnauba wax, but due to its non-domestic production and its dependence on natural growth and harvest me ...

We propose a compact broadband underwater cylindrical transducer with directional capabilities for acoustic communications (ACOMMS) for unmanned underwater vehicles (UUVs) and gliders. Our proposed solution is to incorporate single crystals and directional capabilities into the acoustic modem transducer, thereby increasing overall system capability. BTech has designed and built improved modem tran ...

We propose a compact broadband underwater cylindrical transducer with integrated power amplifier for multiple applications, including acoustic communications (ACOMMS) for unmanned underwater vehicles (UUVs) and gliders. Such compact, modular devices could be used alone or arranged into various array configurations. On existing platforms, the power amplifier and tuning inductor resides within the i ...

This proposal is for the design and development of a new low cost directional acoustic sensor technology with integrated acoustic modem capabilities for distributed sensor systems. The study addresses the feasibility to significant improve legacy performance of current A-size directional sonobuoy sensors with a new sensor and processing approach and to establish performance predictions for the ne ...

A single crystal cylindrical ring transducer with multi-resonant broadband operation is described with counter measure and general purpose sonar applications.

A “Small Buoy for Energy Harvesting” has applications for use on current and future buoy systems used by the submarine fleet of the United States Navy. This work proposes to meet the requirements by converting mechanical wave energy to electrical energy using a generation system housed in a spar buoy. The energy extraction method will work with the natural orientation and motion of the buoy. ...

This SBIR Phase I proposal requests $99739 for Flight Safety Technologies, Inc. to investigate the feasibility and all-weather capability of a novel radar concept as an active, non-cooperative SAA sensor for UAVs. The concept radar, which we call Unicorn, is a narrow-band pulsed radar operating around a center frequency of 5.145 GHz in the aviation C-band, which has been approved for this develop ...
