A UNIQUE HIGH TEMPERATURE, HIGH PRESSURE GASEOUS PHOTOCHEMICAL REACTOR WITH OPTICAL AND MASS SPECTROMETRIC SPECIES DETECTION CAPABILITIES WILL BE DESIGNED. THE PROPOSED DESIGN, UTILIZING AEROCHEM'S EXPERIENCE IN CONSTRUCTING AND USING SIMILAR APPARATUS, WILL EXCEED THE UPPER TEMPERATURE AND PRESSURE SPECIFICATIONS GIVEN IN THE SOLICITATION IN ORDER TO GIVE THE INSTRUMENT GREATER UTILITY. ALTERNATE ...

A NEW DESIGN CONCEPT FOR ELECTRONIC SHELTERS USING SOME OF THE ADVANCED MATERIALS SUCH AS CONDUCTIVE COMPOSITES, AND REINFORCED CONDUCTIVE SILICONE FABRICS WILL BE TESTED. THE MOST RELEVENT APPLICATION PARAMETERS SUCH AS CONDUCTIVITY OF THE COMPOSITES AND FABRICS, THE JOINING MECHANISM TO ENSURE ELECTROMAGNETIC COMPATIBILITY, THE FLEXIBILITY, THE TRANSPORTABILITY AND TOTAL SYSTEM WEIGHT WILL BE AD ...

ALTHOUGH THERE ARE NO INTRINSIC CONFLICTS FOR THE SAME MATERIAL SYSTEMS TO ACHIEVE BOTH THE RADAR ABSORPTION AND THERMAL SUPPRESSION CHARACTERISTICS THERE EXISTS NO COMMERCIAL PRODUCT THAT HAS THE DESIRED DUAL PROPERTIES. A THEORETICAL CALCULATION ON THE FEASIBILITY OF SEVERAL PROPOSED MATERIAL SYSTEMS WILL BE PERFORMED. THE CALCULATIONS ARE BASED ON A MEAN FIELD THEORY FOR DIELECTRIC PROPERTIES. ...

A POLYIMIDE BASED POLYMER ALLOY IS PROPOSED TO BE USED AS THE MATRIX FOR A QUARTZ FILLED MULTILAYER CIRCUIT BOARD. POLYIMIDE WHICH HAS THERMAL EXPANSION COEFFICIENT (TEC) OF 30 PPM/DEG C IS SUBSTANTIATLY LOWER THAN THAT OF EPOXY (50-60 PPM/ DEG C). THE POLYMER ALLOY WHICH CONSISTS OF RIGID-RODLIKE MOLECULES, HOWEVER, WILL HAVE TEC AS LOW AS 10-20 PPM/DEG C. QUARTZ FIBER FILLED IN DIFFERENT GEOMETR ...

This SBIR Phase I project proposes the feasibility study of integrated all-optical 2R regeneration and 3R optical signal regeneration devices for use as high-speed interfaces in satellite applications (solicitation AF04-043). Currently available products achieve regeneration of signals by resorting to Optical to Electrical and then Electrical to optical conversion (OEO), which results in costly, ...

WAFER PROBING IS THE CRITICAL LINK BETWEEN WAFER FABRICATION, AND DEVICE PACKAGING OR HYBRID SUBSYSTEM INSERTION. FOR GAAS MMICS TO BE COST EFFECTIVE, THEY MUST BE TESTED IN A MANNER THAT IS RELIABLE, FAST, AND EFFICIENT. THIS PROPOSAL DESCRIBES A PROGRAM TO DEVELOP EQUIPMENT AND TECHNIQUES FOR HIGH RATE, HIGH VOLUME MMIC WAFER PROBING. PHASE I OF THIS PROGRAM WILL INCLUDE AN EXPERIMENT USING EXIS ...

Development of three Bipropellant Tank designs with mechanically linked pistons for Advanced Small Missile Systems. The study will consider the technical and fabrication issues associated with the design, and rate the comparative merits leading to the selection of Phase II continuation.

The objective of the proposed research is to develop new technologies based on principles of Time Reversal Acoustics (TRA) that will provide highly sensitive land mine detection. We suggest applying the Time Reversal Acousto-seismic method in combination with a nonlinear acousto-seismic mine detection technique. The TRA focused system provides a high concentration of seismic wave energy at any des ...

The objective of this proposal is to develop a Muscle Water Content (MWC) sensor, an ultrasonic device for assessment of body hydration status in soldiers with accuracy better than 2% during deployment and training. The MWC assessment is based on measurement of ultrasound velocity in muscle, which is, to a good approximation, a linear function of the water content. The expected outcome will be ...
