Resin transfer molding (RTM) is a low-cost composites fabrication method used in many commercial products and secondary aircraft structures such as doors. This project investigates a low-cost concept for fabricating higher strength RTM composites enabling their use in primary aircraft structures. The approach uses discrete fiber reinforcements positioned transverse to fabric or through a stiffen ...

THE PROPOSED PHASE I RESEARCH PROJECT WILL EXAMINE ALTERNATIVE METHODS FOR SYNTHESIS OF Y(2)O(3) AND Y(2)O(3)-BASED COATINGS ON CERAMIC FIBERS AND METALLIC PARTICLES FOR USE IN CERAMIC AND INTERMETALLIC BRITTLE MATRIX COMPOSITES. SYNTHESIS METHODS AND HEAT TREATMENT CONDITIONS WILL BE VARIED TO PRODUCE THERMOCHEMICALLY COMPATIBLE COATINGS HAVING A RANGE OF INTERFACIAL SHEAR STRENGTHS FROM NEAR-ZER ...

We propose to design and develop a wireless, light-weight biomedical data acquisition, transmission, and reception system for the interpretation of bioelectrical signals. Examples of biosensing includes sensors measuring voltage signals such as EEG, EKG, EMG, pulse oximetry, blood pressure, and capnography. The proposed WISP system will provide use in battlefield management, in home health care, ...

The Army, and other military and civilian organizations, have a need for large shelters that are air-transportable and rapidly erected in austere conditions. For example, the Army requires an Aviation Maintenance Shelter (AMS) having approximately 75 ft span. Recent advances in high pressure inflatable structures use a braiding process to fabricate seamless airbeams and to make curved airbeams e ...

Fast tuning microwave synthesizer systems are required by the Army for the demodulation of waveforms encoded by spread spectrum techniques. These systems are required as a method of jamming, countermeasures to jamming, secure communications and as low phase noise sources for rapid tuned radar. Our novel approach to these requirements involves the optical heterodyne between two diode laser-pumpe ...

QRC, with subcontractor Texas Instruments, submits this proposal in response to SBIR A96-060 for Wideband Fast Switched RF Synthesizer. The current state of practice of advanced communication and radar systems is to use short on time emitters at any frequency in the in the RF spectrum for various systems. Therefore in support of ESM, ELINT, SIGINT and EA systems, it is necessary to have a method ...

The current market for fast switching frequency sythesizers is growing rapidly. Most synthesizers available today will not meet the stringent requirements for switching quickly, providing spectrally pure RF outputs and minimizing physical size and cost. As part of a current SBIR program, S.T. Research has developed a wideband, fast switching synthesizer, based on the use of broadband phase-locke ...

The proof of concept research explores the potential for integrating the following four 'personal devices's () baseline IFF personal device () data applique interface to field processors () audio applique interface to voice headset or audio monitor () video applique interface to camera and display into a single, wearable non-line of sight spread spectrum IFF, tracking and duplex multimedia com ...

Systems & Processes Engineering Corporation (SPEC) proposes to develop a Waveform Agile Signal Processor (WASP) to support the next generation of fuzing systems and subsystems. WASP is designed to~provide high performance, waveform agile, adaptive signal processing for a variety of RF and optical fuze sensors. WASP is designed to support pulsed time domain, frequency domain, phase, direct sequen ...
