A PROTOTYPE GUIDANCE AND CONTROL SYSTEM SENSOR FOR DIRECTED ENERGY WEAPONS IS PROPOSED. THIS GUIDANCE SUBSYSTEM SENSOR WILL USE THE GLOBAL POSITIONING SYSTEM (GPS) SATELLITE CONSTELLATION FOR BOTH POSITION AND ATTITUDE DETERMINATION OF THE DEW. THIS GPS ATTITUDE DETERMINATION SYSTEM CAN BE CAN BE APPLIED FOR POINTING AND ATTITUDE CONTROL OF MANY TYPES OF DEWS, INCLUDING GROUND, AIR, AND SPACE BASE ...

This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped n-type conducting channel. The 2-D JFET should have excellent high speed, low power characteristics ...

DMS (DILUTED MAGNETIC SEMICONDUCTOR) CRYSTAL WILL MEASURE MAGNETIC FIELD STRENGTHS OF A HYPERVELOCITY GUN (HVG), WITH UNIQUELY HIGH DIRECTIVITY AND SPATIAL RESOLUTION, UNDER A HARSH ELECTRO-MAGNETIC INTERFERENCE (EMI) CONDITION. KNOWLEDGE OF THE MAGNETIC FIELD STRUCTURE BEHIND AND AHEAD OF A PROJECTILE IS ESSENTIAL FOR DESIGNING AN EFFICIENT HVG OF SDI INTEREST, ALTHOUGH EMI MAKES SUCH A MEASUREME ...

OVER THE PAST 6 YEARS, ENTECH HAS DEVELOPED A UNIQUE PRISMATIC COVER FOR PHOTOVOLTAIC CELLS. THE NEW CAST SILICONE COVER OPTICALLY ELIMINATES THE USUAL SHADOWING LOSS CAUSED BY METAL GRIDLINES ON THE ILLUMINATED CELL SURFACE, THEREBY BOOSTING CELL PERFORMANCE TO PREVIOUSLY UNATTAINABLE LEVELS. THE NEW COVER HAS BEEN USED TO SET TEN WORLD RECORDS FOR CELL PERFORMANCE, INCLUDING 31% IN NASA-LEWIS TE ...

THE NEXT GENERATION SPACECRAFT WILL BE MADE OF NEW STRONG, LIGHTWEIGHT MATERIALS WITH LITTLE DAMPING SO THAT ACTIVE VIBRATION SUPPRESSION IS ESSENTIAL. THESE SPACECRAFT, FUNCTIONING IN A REMOTE HOSTILE ENVIRONMENT WHERE IMMEDIATE REPAIR IS PRECLUDED, MAY SUSTAIN DAMAGE FROM EXTERNAL DISTURBANCES AND AGING. TO ADDRESS THE OPERATIONAL REQUIREMENTS OF FUTURE SPACECRAFT, THIS PROGRAM IS DEVELOPING AN ...

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, ...
