Very long wavelength infrared (VLWIR) detectors are highly needed for midcourse phase missile defense. Blocked impurity band detectors are capable of sensing at these wavelengths but require extremely low temperatures, in the 10K or less range. The InAs/GaSb Type II heterostructure system offers unique design flexibility for new innovative detectors. By incorporating dark current reduction techniq ...

The MDA's request to detect, track and discriminate long range targets requires infrared focal plane arrays (IRFPAs) that have higher sensitivities, longer cutoff wavelengths (>14 µm), larger formats (> 256 x 256), and higher operating temperatures than the current infrared technology. PbSnTe is an ideal material for the MDA's requirements. Its carrier mobilities and quantum efficiencies are comp ...

ORBITEC proposes to develop MAELSTROM, an advanced hybrid rocket motor, to meet the demands of highly flexible boost propulsion for Aegis Ballistic Missile Defense applications. Key MAELSTROM features include: versatile energy management, high propulsive performance, inherent safety of a hybrid, non-toxic and insensitive propellants, and a long-term storable system. MAELSTROM combines four ORBI ...

End-to-end communications systems are often so complex that system designers have difficulty keeping track of the constraints, trades, interface requirements, and interdependencies among components. The Communications System Taxonomy (CommTax) and Toolkit proposed herein represents further refinement of an innovative tool that Infinite Global Infrastructures has recently developed internally to as ...

C2BMC is an important component of BMDS. The logistics support tail sustainment challenges in C2BMC are related to the unusual spiral development process employed by C2BMC. Formal metrics such as MTTR and MLDT have not been defined. Nor have spare parts analysis, training needs analysis or documentation support issues been formalized. There is enormous scope for both process re-engineering and tec ...

Many advanced HgCdTe (MCT) infrared detector structures are grown by the molecular beam epitaxy (MBE) technique, which is especially sensitive to small imperfections, impurities, precipitates, and polishing damage on the substrate surface. In order to achieve very high crystalline quality MCT structures, the substrate surface must be of superior quality (MBE-quality). EPIR demonstrated the ability ...

Various oily wastes are generated when performing vehicle maintenance operations, including used oil drained from the engine, the oil filter, and even oil absorbent used to clean up oil that has spilled on the floor. At one time these wastes were placed in landfills. Concerns with oil from these wastes migrating into surface and groundwater has prompted a number of state and federal ...

Lead in household paint and dust is a serious health hazard, as low-level lead exposure can result in a number of adverse health effects, especially in children. Onsite and real-time detection and quantification of lead in paint/dust are very important to homeowners and certified lead-based paint removal professionals. Toward this end, both field-portable equipment (such as X-ray fluorescenc ...

The primary objective of CU Aerospace's Phase I work will be to investigate innovative iodine injection concepts for the chemical oxygen-iodine laser (COIL) that improve mixing at higher total pressures. The designs will be made to significantly improve the pressure recovery of COIL systems while retaining efficiency. The results of the Phase I research will lay the foundation for developing a h ...
