N/A

MANY CURRENT AND PLANNED DEFENSE AEROSPACE PROGRAMS DEPEND CRITICALLY UPON RAPID DEVELOPMENT OF LIGHTWEIGHT COMPOSITE MATERIALS HAVING UNPRECEDENTED HIGH-TEMPERATURE PROPERTIES. CONTINUOUS FIBER REINFORCED INTERMETALLIC MATRIX COMPOSITES (IMC'S) HAVE THE POTENTIAL TO MEET THESE PERFORMANCE REQUIREMENTS, AND CONSIDERABLE RESEARCH EFFORT IS NOW DEVOTED TO DEVELOPING THEM. WE RECENTLY DEMONSTRATED A ...

N/A

Essential Research, Inc. proposed to develop an ultra-high efficiency, dislocation-free, monolithic two-terminal, two-junction InGaP/InGaAs on Ge solar cells for space applications. The energy bandgap (Eg) values for the top and bottom cells will be 1.7 eV and 1.1 eV, respectively. These bandgaps are theoretically optimal for a two-junction tandem cell configuration. This solar cell will have a pr ...

N/A

InP based heterojunction bipolar transistors (HBTs) exhibit proven potential for use in high performance digital integrated circuits and discrete microwave components. For high speed applications, it is desirable to utilize structures that have been designed to promote high levels of nonequilibrium electron transport as this allows realization of higher electron velocities than possible for diffus ...

Novel ionic self-assembled monolayer (ISAM) processes for the fabrication of advanced electronic materials and devices will be developed through this program. Revolutionary ISAM methods to create nanostructured multi-layer inorganic/organic thin-films offer major advantages over conventional manufacturing processes, since the process is simple, low-cost and environmentally friendly in that no vola ...

F&S and Virginia Tech will cooperatively develop high performance protective ionic self-assembled monolayer (ISAM) organic/inorganic coatings for space-based optical and structural components, and work with Litton to upscale practical coating manufacturing. Revolutionary ISAM methods of creating multi-layer protective nanopartwcle films offer major advantages over con-ventional coating processes, ...

We offer an approach to a multiple-order-of-magnitude processing speed/efficiency improvement in vector quantization (VQ) data/image compression, automatic target recognition/classification, and time signal/signature classification. We base our approach on an algorithmic breakthrough, the TABULAR NEAREST-NEIGHBOR ENCODER (TNE), which we discovered and partially developed last year. This algorithm ...

Current rare earth permanent magnets have proven to be in adequate for higher temperatures (300-500_C) military and Air Force applications. Development of permanent magnetic materials which can operate in high temperature regime will enable design of simpler, more efficient magnetic systems. The More Electric Aircraft (MEA) concept pursued by the US Air Force drives this need. We propose a novel p ...
