APPLIED TECHNOLOGIES, INC. PROPOSES A DESIGN PROGRAM TO DESIGN A SIMPLE, MOBILE, VERTICAL AXIS FM-CW RADAR. THE PROGRAM WILL ENCOMPASS A LITERATURE SEARCH TO FIND THE LATEST STATE-OF-THE-ART ADVANCES IN RADAR TECHNOLOGY. THE DATA FROM THE LITERATURE SEARCH WILL FORM THE BASIS FOR A DESIGN THAT INCLUDES ANTENNA DESIGN, TRANSMITTER DESIGN, RECEIVER DESIGN, AND DATA COLLECTION AND PROCESSING. COST TR ...

THE OBJECTIVE OF THE PROPOSED WORK IS TO ANALYZE THE HYPERVELOCITY MODELS TESTED AT ARNOLD ENGINEERING DEVELOPMENT CENTER TO DETERMINE THE CAUSE OF NOSETIP FRACTURES. WE WILL ACCOMPLISH THIS GOAL BY PERFORMING TWOAND THREE-DIMENSIONAL FINITE ELEMENT ANALYSES OF THE HYPERVELOCITY MODEL USING DYNA2D AND DYNA3D. IF NECESSARY, WE WILL ALSO DO HYDRODYNAMIC ANALYSES OF THE GAS EXPANSION WHICH DRIVES THE ...

THE OVERALL GOAL OF PHASE I AND PHASE II IS TO DEVELOP SOFTWARE THAT WILL FIND THE OPTIMAL SIZE AND SHAPE OF MARB DESIGNS ACCORDING TO USER DEFINED DESIGN CRITERIA. PHASE I WILL SHOW THE FEASIBILITY OF MARB SHAPE DESIGN OPTIMIZATION BY COMBINING A GEOMETRIC MODELER, OPTIMIZATION SOFTWARE, AND FREE-FORM DEFORMATION WITH AN ANALYSIS MODULE. THE PHASE I ANALYSIS MODULE WILL CONTAIN AERODYNAMICS AND I ...

INCREASES IN SOLAR CELL EFFICIENCY CAN BE ACHIEVED WITH TANDEM MULTI-JUNCTION STRUCTURES TO IMPROVE THE PERFORMANCE AND SCALE OF SPACE PHOTOVOLTAIC CONCENTRATORS. THE "TOP SOLAR CELL" TANDEM APPROACH COULD INCREASE ENERGY CONVERSION EFFICIENCY BY AS MUCH AS 100%. A SELF-SUPPORTING ALUMINUM-GALLIUM-ARSENIDE (ALGAAS) TOP SOLAR CELL IS BEING DEVELOPED FOR MECHANICAL ATTACHMENT TO A SILICON CONCENTRAT ...

EXISTING METALLIC-TYPE CONTACTS ON GALLIUM ARSENIDE (GAAS) HAVE NOT BEEN STABLE AT HIGH TEMPERATURES BECAUSE OF INTERDIFFUSION AND/OR ALLOYING OF THE GAAS TOP LAYER. HIGH TEMPERATURE CONTACTS TO GAAS SPACE PHOTOLTAIC CELLS ARE BEING DEVELOPED BASED ON THE FORMATION OF A HIGHLY-STABLE INTERMEDIATE DEGENERATE SEMICONDUCTOR LAYER BETWEEN THE GAAS AND A HIGH TEMPERATURE METAL ALLOY. THE INTERMEDIATE S ...

UNIFORM LARGE AREA, DEVICE QUALITY INDIUM PHOSPHIDE (INP) EPITAXIAL LAYERS ON INSULATING SUBSTRATES COULD LEAD TO THE DEVELOPMENT OF A NEW GENERATION OF PRODUCIBLE, RADIATION-HARDENED MICROELECTRONIC AND OPTOELECTRONIV INTEGRATED CIRCUITS. INP ALLOYS OFFER THE ADVANTAGES OF: PROVEN RESISTANCE TO RADIATION DAMAGE; LOWER SURFACE RECOMBINATION THAN GAAS; HIGH PEAK ELECTRON VELOCITY; AND BANDGAPS THAT ...

HIGH TEMPERATURE (>600 DEGREES CELSIUS) INDIUM PHOSPHIDE (INP) SPACE SOLAR CELLS ARE BEING DEVELOPED TO ELIMINATE THEPROBLEMS, SURFACE DECOMPOSITION AND CONTACT FAILURE, ENCOUNTERED WHEN INP SOLAR CELLS ARE EXPOSED TO HIGH TEMPERATURES. KEY TO THIS PROGRAM ARE THE USE OF AN ENCAPSULANT LAYER TO ARREST SURFACE DECOMPOSITION AND A HIGHLY-STABLE INTERMEDIATE DEGENERATE SEMICONDUCTOR CONTACT SYSTEM DE ...

SOLID-STATE LASER SYSTEMS HAVE BEEN IDENTIFIED AS A PARTICULARLY EFFECTIVE TRANSMITTER TECHNOLOGY FOR USE IN COHERENT LASER RADAR SYSTEMS, DUE TO THEIR NEAR-IR WAVELENGTH (1-2UM), COMPACTNESS, FREQUENCY AGILITY, AND EFFICIENCY. RECENT ADVANCES IN LASER DIODE ARRAY TECHNOLOGYHAVE OPENED NEW PROSPECTS FOR LONG LIFE, HIGH ENERGY AND AVERAGE POWER SOLID-STATE LASER RADAR INSTRUMENTS SUITABLE FOR EXTEN ...

A HYPERGOLIC FUEL INJECTOR IS DESCRIBED THAT ENABLES MULTIFUEL OPERATION, LOWER FUEL CONSUMPTION, AND ENHANCED ALL WEATHER STARTING FOR INTERNAL COMBUSTION ENGINES. THE DEVICE EMPLOYS A NOVEL DUAL FUNCTION HIGH PRESSURE PUMP PERMITTING THE TRANSPORT OF HEATED FUEL IN A FUEL INJECTOR SUITABLE FOR USE IN SUCH ENGINES. HIGH TEMPERTURE AND VERY HIGH PRESSURE FUEL IS DELIVERED TO THE COMBUSTION SPACE O ...

THE ADVENT OF THE CORDRAY ROTARY ENGINE HAS MADE POSSIBLE SUBSTANTIAL INCREASES IN THE POWER TO WEIGHT RATIO AVAILABLE TO THE AIRCRAFT DESIGNER. ENGINE SELECTION IS HISTORICALLY THE PRIMARY DETERMINATIVE OFVEHICLE DESIGN AND PERFORMANCE. THE AVAILABILITY OF THIS ENGINE ALONGWITH ADVANCES IN COMMAND AND CONTROL ELECTRONICS MAKES POSSIBLE A NEW CLASS OF VEHICLE CAPABLE OF VERTICAL TAKE OFF AND THEN ...
