The Award database is continually updated throughout the year. As a result, data for the given year is not complete until April of the following year. Annual Reports data is a snapshot of agency reported information for that year and hence might look different from the live data in the Awards Information charts.

  1. GENERATION OF LARGE OPTICAL SURFACES THROUGH CNC THERMALLY ASSISTED DUCTILE REGIME GRINDING

    SBC: Sensintel Inc.            Topic: N/A

    DUCTILE CHIP FORMATION, UNLIKE THE BRITTLE CHIP FORMATION TYPICALLY OBSERVED IN DIAMOND GRINDING OF CERAMICS, DOES NOTLEAVE BEHIND SURFACE OR SUBSURFACE MICROCRACKS. ACCORDINGLY, MACHINE PROCESSES INVOLVING POLISHING CAN BE ELIMINATED FROM FABRICATION IF MATERIAL REMOVAL DURING GRINDING OCCURS THROUGH DUCTILE CHIP FORMATION. DUCTILE CHIP FORMATION IS ESSENTIALLY AN EXTRUSION PROCESS IN WHICH AN IN ...

  2. VISUAL MOTION FOR ROTORCRAFT GUIDANCE

    SBC: Advanced Decision Systems            Topic: N/A

    FOR ROTORCRAFT IN A NAP-OF-THE-EARTH (NOE) FLIGHT REGIME, COLLISION WITH WIRES PRESENTS A SIGNIFICANT THREAT TO SAFETY. WIRE DETECTION AND AVOIDANCE IS THUS AN IMPORTANT PART OF SAFE NOE GUIDANCE. WIRE DETECTION CAN BE DIFFICULT:WIRES ARE OFTEN NOT STRONGLY SPATIALLY EVIDENT, DANGEROUS WIRES OFTEN OCCUR AT THE FOCUS-OF-EXPANSION (FOE), THERE IS OFTEN SIGNIFICANT BACKGROUND CLUTTER AND NOISE, AND T ...

  3. THERMIONIC NETCON FOR OUT-OF-CORE SPACE POWER SYSTEM

    SBC: Advanced Energy Technology,            Topic: N/A

    NETCON (NEW THERMIONIC CONVERTER) IS A NEW IDEA FOR AN ADVANCED POWER CONVERSION SYSTEM. THE EMITTERS ARE TYPICALLY 0.5 CM IN DIMENSION. THE EMITTER AND COLLECTOR ARE SEPARATED BY LESS THAN 0.5 MILS ( 12 MU M), WITH OPERATION IN THE QUASI-VACUUM (UNIGNITED) MODE. THE INTERELECTRODE GAP IS SET BY THE THERMAL EXPANSION OF A CERAMIC PEDESTAL SUPPORTING THE EMITTER. HEAT TRANSPORT TO THE EMITTER IS BY ...

  4. AN INTEGRATED-FUNCTION X-RAY LABORATORY FOR THE GEOLOGICAL AND EXOBIOLOGICAL

    SBC: Aracor            Topic: N/A

    THE PROPOSED R&D WILL ESTABLISH A NEW CAPABILITY OF LIGHT-ELEMENT X-RAY FLUORESCENCE ANALYSIS THAT SUPPORTS THE ACCURATE QUANTITATIVE MEASUREMENT OF THE BIOGENIC ELEMENTS. THE BASIS FOR THIS NEW CAPABILITY IS A CLASS OF INNOVATIVE X-RAY WAVELENGTH-DISPERSIVE OPTICAL COMPONENTS KNOWN AS LAYERED SYNTHETIC MICROSTRUCTURES (LSM). THESE COMPONENTS, WHEN COMBINED WITH EXISTING ENERGY-DISPERSIVE DETECTOR ...

  5. AUTOMATED RADIATION/RELIABILITY VLSI QUALIFICATION

    SBC: Aracor            Topic: N/A

    THE DEVELOPMENT OF AN AUTOMATED TEST METHOD TO EXTRACT CMOS VLSI CIRCUIT PARAMETERS TO ASSESS HOT-ELECTRON RELIABILITY AND RADIATION HARDNESS IS PROPOSED. THE INSTRUMENT, COMBINED WITH STANDARDIZED TEST CHIPS, WOULD BE UNIQUELY SUITED FOR QUALIFICATION OF LOW-VOLUME ASIC CIRCUITS FOR SPACEBOURNE APPLICATIONS. THE PROPOSED CONCEPTINCLUDES THE DEVELOPMENT OF AUTOMATED TRANSFER OF TEST DEVICES BETWEE ...

  6. PASSIVE PROPELLER CONTROL

    SBC: AEROVIRONMENT, INC.            Topic: N/A

    VERY-HIGH-ALTITUDE, LONG-ENDURANCE (VHALE) TYPE AIRCRAFT OPERATE OVER A WIDE POWER RANGE DUE TO ALTITUDE AND FUEL LOAD CHANGES. MATCHING THE PROPELLER TO THE ENGINE OVER THIS RANGE IS DIFFICULT WITHOUT A COMPLICATED VARIABLE-PITCHPROPELLER OR GEARING. PASSIVE, OPTIMAL-PITCH CONTROL IS THEGOAL OF THIS PROJECT. THE CONCEPT CONSISTS OF AN AERODYNAMICALLY TAILORED BLADE, BALANCE WEIGHTS, AND TORSIONAL ...

  7. SIMULTANEOUS MEASUREMENT OF TEMPERATURE, SIZE, AND VELOCITY OF DROPS IN SPRAYS

    SBC: Aerometrics Inc.            Topic: N/A

    MOST POWER PLANTS CURRENTLY BEING USED FOR AERONAUTICAL PROPULSIVE PURPOSES FUNCTION BY BURNING LIQUID FUELS IN THEIR COMBUSTION CHAMBERS. THEREFORE, THE DESIGN AND DEVELOPMENT OF EFFICIENT PROPULSION SYSTEMS REQUIRE THE COMPLETE UNDERSTANDING OF SPRAY COMBUSTION PROCESSES. TOWARDS THIS END, SEVERAL THEORETICAL MODELS HAVE BEEN DEVELOPED OVER THE YEARS, BUT THEIR CAPABILITIES ARE STILL OPEN TO QUE ...

  8. COMPACT RUGGED LASER DOPPLER VELOCIMETER PROBE FOR IN-FLIGHTGAS TURBINE INLET FLOW MEASUREMENT

    SBC: Aerometrics Inc.            Topic: N/A

    N/A

    SBIR Phase I 1991 National Aeronautics and Space Administration
  9. FOCAL PLANE IMAGE COMPRESSION IN THE CHARGE DOMAIN

    SBC: Altadena Instruments            Topic: N/A

    THIS PROJECT ADDRESSES CHARGE-DOMAIN IMAGE COMPRESSION ON A MONOLITHIC CHARGE-COUPLED DEVICE (CCD) DETECTOR. SUCH A DEVICE WOULD HAVE SUBSTANTIALLY REDUCED OUTPUT BANDWIDTH COMPARED WITH EXISTING PIXEL-BY-PIXEL READOUT SYSTEMS. BECAUSE CURRENT IMAGE COMPRESSION ALGORITHMS CAN PROVIDE COMPRESSION FACTORS OF GREATER THAN 10:1 WITH LITTLE VISIBLEDEGRADATION, A CHARGE-DOMAIN COMPRESSOR CCD COULD REDUC ...

  10. GAS TURBINE NOISE REDUCTION

    SBC: Altex Technologies Corporation            Topic: N/A

    REDUCTION OF GAS TURBINE PROPULSION SYSTEM NOISE, AND ASSOCIATED VIBRATIONS, IS AN IMPORTANT GOAL FOR FUTURE AIRCRAFT. THE OBJECTIVE OF THIS PROJECT IS TO USE AN INNOVATIVE METHODOLOGY TO IDENTIFY AND QUANTIFY THE PRIMARY SOURCE OF NOISE IN GAS-TURBINE COMBUSTORS AND USE THE RESULTS TO IDENTIFY A HIGH-POTENTIAL, NOISE-AVOIDANCE CONCEPT. AN INNOVATIVE UNSTEADY FLOW MODEL WILL BE USED TO IDENTIFY AN ...
