Accudyne proposes a SBIR program, endorsed by Sikorsky, Cytec Engineered Materials, and NASA-LaRC, to develop a cost-effective thermoplastic automated tow placement (ATP) process and demonstrate it by fabricating and testing a complex contoured skin (Phase 1) and a CH-53K rotorcraft lower cabin or ramp skin (Phase 2). The process employs in situ consolidation, avoiding the autoclave. The targete ...

This proposal will supply to NAVAIR and to rotorcraft manufacturing companies the emerging solution to their fabrication needs as it relates to the production of Rotor Blade Spars. The process and machine concept developed in Phase I will provide NAVAIR and the rotocraft manufacturing companies an automated solution to spar manufacturing. This will enable: • Low part manufacturing cost • High ...

ACTIVATED STEEL FOIL FABRICATED INTO ELEMENTS TO BE PACKAGED AS EXPENDABLE DECOYS HAS SHOWN GOOD PERFORMANCE IN LOW IR SIGNATURE APPLICATIONS. THE PRESENT BATCH PRODUCTION PROCESS FOR THESE FOILS ENTAILS, IN PART, TWENTY HOURS OF FURNACE TREATMENT. A COMBINATION OF NINE SEPARATE OPERATIONS, LOW PRODUCTION RATES AND HIGH LABOR COSTS YIELDS A UNIT MANUFACTURING COST OF MORE THAN $250.00. WE PROPOSE ...

In this proposal, AlphaSense, Inc. (AI) and the University of Michigan (UM) detail the development of a compact, portable, and low cost in-process weld defects detection system. Key innovations of the proposed system include: a) weld defects monitoring based on plasma emission characteristics; b) use the electron temperature of the plasma as an indicator of the weld quality, c) use multiple plasma ...

In this proposal, AlphaSense, Inc. (AI) and the Oklahoma State University (OKState) detail the development of a novel Cavity Enhanced Terahertz Absorption Spectrometer (CETAS). Key innovations of the proposed system include: a) the use of a small Whispering- Gallery- Mode (WGM) cavity to achieve very long pathlength; and b) the integration of the WGM cavity with the conventional pulsed and continu ...

ANP Technologies proposes to integrate a commercially available air sample concentrator from ICx MesoSystems with our automated detection instrument that uses the NIDS® multiplexed assays and NIDS® Auto-Reader (AR) device. A trigger device may also be incorporated into the final system, which might better enable the system to serve as a remote monitor of air streams. The proposed effort will b ...

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 ...
