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 ...

This proposal presents a Phase II SBIR project to produce prototypes of the automated high precision, low disperse rate powder disseminator for the US Army, that has been successfully designed and analyzed in the Phase I project. In the development of the sensitive detecting agent, we need to release a precise amount of C&B agents in the controlled detection experiments. At the end of this Phase ...

DESCRIPTION (provided by applicant): This project encompasses development and testing of a concatenative text-to-speech (TTS) synthesis system known as ModelTalker and software called InvTool which guides individuals in creating personal synthetic voices for use with ModelTalker. The overall system is intended to be of particular interest to Augmentative and Alternative Communication (AAC) device ...

The feasibility of ANP's proposed seld-calibrated rapid test forf AChE inhibitors has been clearly shown in Phase I. Its compatability with ANP's handheld reader for immuno-assay based threat agent rapid testing has been confirmed. Phase II will finalize the design for robustness, full integration with the ANP handheld reader, manufacturing and affordability. Expansion of testing to include a w ...

Longer-lived stripper foils operating in present-day DOE accelerator facilities, with elements up to mass 100, would provide substantial operating savings and reduced radiation exposure to maintenance personnel. However, the next generation of rare isotope facilities would need even more robust stripper foils to survive exposure to higher-power density beams of even heavier elements, up to uraniu ...

The detection and classification of reentry vehicles in the presence of jammers and clutter is a very important missile defense radar problem. High resolution, wideband adaptive beamforming (ADBF) is an important solution component in which both the transmit and receive beamforming weight vectors are dynamically updated to optimize performance in a time varying jammer and clutter environment. An i ...

This proposal will address the development of digital receivers and exciters capable of supporting > 1 GHz of instantaneous bandwidth (IBW). The technology will be used in large scalable BMD radar arrays employing a digital waveform generator and digital receiver at the analog input/output of each subarray panel. The receivers/exciters include the necessary up/downconversion and local oscillator c ...

In the proposed Phase II effort, Applied Radar, Inc. will develop a wideband scaleable digital beamforming (DBF) processor capable of supporting > 1 GHz of instantaneous bandwidth (IBW). The new patented hardware architecture paradigm developed in Phase I is scaleable in the number of input channels, the number of output beams, and bandwidth. Hence, it is directly applicable to large BMD radars su ...

The development of broadband high-isolation active circulators with simultaneous transmit and receive (STAR) capabilities would enable increased persistence in intelligence, surveillance and reconnaissance (ISR) systems and allow multiple simultaneous radar modes including SAR, GMTI and AMTI for global and local multifunction and multi-task operations. Previous works in MMIC active circulators dem ...

Our missile defense capability crucially depends on radar performance to detect, track and discriminate hostile targets. New radar designs being developed offer enhanced capability. However, a significant impediment to the deployment of these new radars is the high cost of active electronically scanned arrays (AESAs) and in particular the antennas upon which they are based. Together with our inter ...
