ABSTRACT: This program targets development of a high-performance thermoelectric (TE) cooler with a figure-of-merit, ZT>3, which greatly exceeds currently available technology. The cooler is fabricated using Group II-VI compound semiconductors, i.e. HgCdSe or HgCdTe, using a low dimensional structure know as a"superlattice"(SL). The proposed TE coolers will operate at temperatures ranging from 5 ...

ABSTRACT: Accurate prediction of part performance/reliability is at the core of health management of air vehicles and of supply chain management. Methodologies are needed to accurately predict/evaluate parts performance/reliability with compounding problem criteria/factors for early corrective actions and acquisition of aerospace parts. Accurate problem part (bad actor) identification and resou ...

The use of advanced composite materials in all applications has increased dramatically, but the methods for managing and processing have remained unchanged for thirty years. Advanced, mulitple sensor technology has been demonstrated to reduce process time and costs. AvPro proposes to develop a single sensor system to provide multiple data inputs. It would be a means to validate models for proce ...

TMSSequoia proposes to develop a software system to allow conversion of paper-based legacy engineering drawings, technical manuals and reports, to a digital format. This process will include automatic extraction of data from the scanned images that is input into a Configuration Management Information System (CMIS) for storage, query and retrieval. TMSSequoia will then identify current software t ...

The need for small portable, low-cost instruments for field environmental measurements is well documented. Nomadics is developing powerful handheld instruments based on the portable computers and PCMCIA cards. We intent to marry existing proven (but not yet deployed) sensor technologies with portable computers (such as laptops, palmtops and PDAs) using the industry standard PCMCIA card and virtu ...

DEVELOPMENT OF A PLAN AND ITS DEMONSTRATION IN PRODUCING MODERN DATABASE FOR RV TECHNOLOGIES IS PROPOSED BY USING CLOUD MICROPHYSICAL DATA SETS COLLECTED SINCE 1985 OVER THE NORTH AMERICAN CONTINENT AND U.S. ARMY KWAJALEIN ATOLL. THE PLAN INCLUDES THE USE OF AIRBORNE RADAR, MODELING, AND SATELLITE ADDITIONS TO THE PARTICLE SIZE DATA TO CORRELATE PARTICLE SIZE AND LIQUID WATER CONTENT OVER AN EXTEN ...

THE PLANNED INCREASED USAGE BY THE AIR FORCE OF BIPROPELLANT SYSTEMS SUCH AS NITROGEN TETROXIDE AND MONOMETHYL HYDRAZINE FOR SPACECRAFTS REQUIRES THAT A PROCESS PRODUCING ESSENTIALLY PURE LIQUID NITROGEN TETROXIDE BE DEVELOPED. LIQUID NITROGEN TETROXIDE CURRENTLY PRODUCED BY AVAILABLE TECHNIQUES CONTAINS IMPURITIES WHICH CAN CLOG FILTERS AND VALVES ON BIPROPELLANT SYSTEMS. LABORATORY PREPARATION O ...
