  1. A RELIABLE, MECHANICAL CRYOCOOLER FOR 80 K COOLING IN SPACE

    SBC: Alabama Cryogenic Engineering, Inc.            Topic: N/A

    THIS PROPOSAL COVERS THE DEVELOPMENT OF A 0.25 WATT, 80 K MECHANICAL CRYOCOOLER FOR USE IN SENSOR COOLING IN SPACE. THE CRYOCOOLER WILL USE THE MIKULIN PULSE TUBE CYCLE THAT HAS NO MOVING PARTS IN THE COLD SECTION OF THE CRYOCOOLER. THE ELIMINATION OF COLD MOVING PARTS REMOVES THE MAIN SOURCES OF FAILURE AND OF VIBRATION IN THE CRYOCOOLER. LIFETIMES OF OVER FIVE YEARS SHOULD BE POSSIBLE WITH THIS ...

  2. EXPERT SYSTEM FOR FINITE ELEMENT MODELING

    SBC: Autodesk Inc.            Topic: N/A

    MOST TYPICAL PROBLEMS IN STRUCTURAL ENGINEERING ARE BEST ANALYZED BY APPROXIMATING AN OBJECT'S GEOMETRY WITH FINITE ELEMENTS. SELECTING AN APPROPRIATE MESHING STRATEGY FOR A GIVEN SOLID REQUIRES KNOWLEDGE ABOUT FINITE ELEMENT THEORY IN GENERAL, AND ABOUT PACKAGE-SPECIFIC DETAILS IN PARTICULAR. THE ADEPT SYSTEM INTEGRATES A TRADITIONAL SOLIDMODELER WITH AN EXPERT SYSTEM EQUIPPED WITH THIS KNOWLEDGE ...

  3. TACTILE TELEPRESENCE SYSTEM FOR DEXTEROUS TELEROBOTICS

    SBC: Begej Corp.            Topic: N/A

    THE OBJECTIVE OF THIS PROJECT IS TO DESIGN AND FABRICATE AN INNOVATIVE FINGERTIP-SHAPED TACTILE TELEPRESENCE SYSTEM FOR DEXTEROUS TELEROBOTIC SYSTEMS. THE PRINCIPAL TASKS TO BE PERFORMED ARE: (1) DESIGN OF VARIOUS MINIATURE TACTILE STIMULATOR ELEMENTS AND EVALUATION OF THE ACTUATION STRENGTH, DISPLACEMENT MAGNITUDE, FREQUENCY RESPONSE RANGE, AND THERMAL LOADING CHARACTERISTICS, (2) CONSTRUCTION OF ...

  4. HIGH SPATIAL RESOLUTION/LARGE FIELD OF VIEW DETECTOR AND DATA HANDLING SYSTEM FOR A SPACE BASED SOLAR VECTOR MAGNETOGRAPH

    SBC: Bgb Inc.            Topic: N/A

    CIVILIAN AND MILITARY SPACECRAFT SYSTEMS, COMMUNICATIONS, DETECTION, TRACKING AND SURVEILLANCE ACTIVITES CAN BE ENDANGERED OR DEGRADED BY SOLAR ACTIVITY. THE SUN INDUCES THESE DISTURBANCES THROUGH MAGNETIC FIELD DISTURBANCES, ELECTROMAGNETIC AND CHARGED PARTICLE IRRADIATION OF THE EARTH'S UPPER ATMOSPHERES. ONE METHOD OF CIRCUMVENTING SERIOUS CONSEQUENCES OF THIS ACTIVITY IS THROUGH SPACE BASEDMON ...

  5. MODELING OF TURBULENT SPRAY COMBUSTION IN LIQUID ROCKET ENGINE COMPONENTS

    SBC: CFD Research Corporation            Topic: N/A

    FUNDAMENTAL PHYSICS OF THE COMBUSTION PROCESSES IN LIQUID ROCKET ENGINES IS VERY COMPLEX. RECENT ADVANCES IN COMPUTATIONAL FLUID DYNAMICS (CFD) PROVIDE A BASIC MECHANISM FOR DETAILED ANALYSES. THE EXISTENCE OF CFD TECHNIQUES INCREASES THE NEED OF ADEQUATE MODELS FOR PHYSICAL PROCESSES, SUCH AS: ATOMIZATION AND SPRAY FORMATIONUNDER SUB AND SUPERCRITICAL CONDITIONS, DROPLET-DROPLET INTERACTION, TURB ...

  7. COMPUTATIONAL METHODOLOGIES FOR CONVECTION-DIFFUSION PHASE CHANGE PROBLEMS

    SBC: Cham Of North America Inc            Topic: N/A

    THE OBJECTIVE OF THIS PROJECT WAS TO DEVELOP NUMERICAL METHODOLOGIES FOR ANALYZING SOLID-LIQUID PHASE CHANGE PROBLEMS INVOLVING MULTI-COMPONENT MATERIALS SUCH AS BINARY MIXTURES AND ALLOYS. THE POTENTIAL NASA INTEREST FOR THIS WORK STEMS FROM MATERIALS SCIENCE APPLICATIONS IN SPACE, E.G. CRYSTAL GROWTH. THE AIM OF PHASE I WAS TO DEFINE A FRAMEWORK FOR DEVELOPMENTOF A GENERAL PURPOSE COMPUTER PROGR ...

  8. ASYNCHRONOUS MULTILEVEL ADAPTIVE METHODS FOR PARTIAL DIFFERENTIAL EQUATIONS ON THE NAVIER-STOKES COMPUTER

    SBC: Colorado Research Development            Topic: N/A

    NASA IS CURRENTLY SUPPORTING A VERY PROMISING PROJECT FOR DEVELOPMENT OF A HIGH-POWERED MULTIPROCESSOR SYSTEM, THE NAVIER-STOKES COMPUTER (NSC). WHILE MULTILEVEL ALGORITHMS ARE BEING STUDIED IN THE NSC ENVIRONMENT FOR SOLVING THE ELLIPTIC EQUATIONS THAT ARISE IN DISCRETIZING INCOMPRESSIBLENAVIER-STOKES EQUATIONS, NO RESEARCH HAS YET FOCUSED ON LOCAL ADAPTIVE SCHEMES FOR THIS PURPOSE. THIS IS IMPOR ...

    SBIR Phase I 1988 National Aeronautics and Space Administration
  9. SYMBOLIC IMAGERY MANAGEMENT SYSTEM (SIMS)

    SBC: Command Control, Inc.            Topic: N/A

    THE USE OF IMAGERY FOR THE PRESENTATION OF DATA IS BECOMING INCREASINGLY COMMON. INTEGRATING IMAGE DATA WITH GRAPHIC DATA STRUCTURES AND FEATURE INFORMATION IS VERY DIFFICULT USING TRADITIONAL DIGITAL REPRESENTATIONS. SEPARATE IMAGE AND FEATURE INFORMATION DATABASES ARE COMMONLY USED, BUT THE ANALYST IS REQUIRED TO MAINTAIN TWO OR MORE DATABASES AND TO PERFORM INTEGRATION OF THE INFORMATION IN HIS ...

  10. TEMPERATURE MEASUREMENT BY NONCONTACT METHOD FOR CZOCHRALSKITYPE CRYSTAL GROWTH

    SBC: Electro Design Manufacturing            Topic: N/A

    IN THE GROWTH OF CRYSTALS FROM MELTING MATERIALS USING THE CZOCHRALSKI METHOD, A GOOD TECHNIQUE OF ACCURATELY CONTROLLING THE PROCESS DOES NOT EXIST. THERMOCOUPLES ARE LARGELY USED AT PRESENT, BUT THEY DO NOT PROVIDE ADEQUATE INFORMATION SUCH AS THE THERMAL GRADIENT ACROSS A SINGLE LARGE CRYSTAL. THE USE OF CHARGE-COUPLED DEVICES TO MEASUREAND CONTROL CRYSTAL GROWTH USING THE CZOCHRALSKI METHOD IS ...
