N/A

RECENT DEVELOPMENTS IN THE MANUFACTURE OF METAL MATRIX COMPOSITE PRECURSORS BY PHYSICAL VAPOR DEPOSITION TECHNIQUES HAVE CREATED AN OPPORTUNITY TO FABRICATE HIGH-QUALITY, FINE-GAGE COMPOSITE WIRES HAVING PRECISE DIMENSIONS AND FIBER VOLUME FRACTIONS. SPECIALLY DESIGNED DIES WILL BE USED TO DRAW ION-PLATED GRAPHITE/ALUMINUM AND GRAPHITE/MAGNESIUM COMPOSITE TAPES INTO 1.8-MM DIAMETER COMPOSITE WIRES ...

N/A

RECENT ADVANCES IN THE UNDERSTANDING OF FLIGHT AT POST STALL CONDITIONS HAVE SHOWN A POTENTIAL MANEUVERING BENEFIT IN ALLOWING QUICKER MORE AGILE TURNING WITH AN ATTENDANT TIME ON TARGET ADVANTAGE. FURTHERMORE, STALL AND SPIN RECOVERY HAS BEEN SHOWN TO BE MADE MORE EFFECTIVE USING A COMPANY PATENTED, MODIFIED HORIZONTAL CONTROL SURFACE. THIS PROJECT (PHASE I) IS AIMED AT DEVELOPING METHODS FOR THE ...

THIS PROJECT INVOLVES A DESIGN STUDY AND DEVELOPMENT OF A MULTI-ELEMENT HIGH REYNOLDS NUMBER NLF AIRFOIL THAT MINIMIZES THE TURBULENT SEPARATION PROBLEM AT OFF DESIGN CONDITIONS. THE CONCEPT DEVELOPMENT WILL UTILIZE AN INTEGRATED MULTI-ELEMENT AIRFOIL SYSTEM TO BE DESIGNED TO FORM A SLOT BETWEEN THE UPPER AND LOWER SURFACE IN THE TURBULENT RECOVERY REGIONS. THIS SLOT BRINGS HIGHER ENERGY AIR FROM ...

SUPERCRITICAL (SC) LOW DRAG LFC AIRFOILS WITH HIGH DESIGN MACH NUMBERS OFFERING AN INCREASED OPERATING RANGE, WIDER HIGH SPEED BUFFET MARGINS (PREFERABLY WITHOUT BOUNDARY LAYER SUCTION IN THE REGION OF THE SPANWISE BENDING MATERIAL FOR COMPOSITE WINGS) AND SMALLER LIFT LOSS WITH TURBULENCE AT INTERMEDIATE MACH NUMBERS WILL BE DEVELOPED. INCREASED CLMAX NLF AND "HYBRID" TYPE SC LAMINAR FLOW AIRFOIL ...

EDDY CURRENT FIELD INSPECTIONS ARE PRESENTLY PERFORMED BY TECHNICIANS WHO MUST EXAMINE AND EVALUATE THE OUTPUT OF EDDYCURRENT EQUIPMENT AND MANUALLY RECORD THE RESULTS OF SUCH INSPECTIONS. AN INVESTIGATION INTO THE FEASIBILITY OF IMPLEMENTING A DIGITAL SYSTEM WHICH AUTOMATES THIS PROCESSS IS THE OBJECTIVE OF THIS STUDY. THE SYSTEM IS BASED UPON A GENERAL PURPOSE, LOW-COST PERSONAL COMPUTER. IT AUT ...

N/A

THIS PROJECT WILL DEVELOP A HIGH SPEED, DC BRUSHLESS, PERMANENT MAGNET TRACTION MOTOR USING NEODYMIUM BORON IRON AS THE PERMANENT MAGNET MATERIAL AND AN INTEGRAL SINGLE STAGE PLANETARY GEAR REDUCTION. THE MAGNET MATERIAL, NEWLY INTRODUCED AND DISCUSSED AT THE MMM CONFERENCE IN PITTSBURGH IN NOVEMBER 1983 AND THE INTERMAG CONFERENCE IN GERMANY IN APRIL 1984, HOLDS THE POTENTIAL FOR SIGNIFICANT SIZE ...

EXPERIENCE IN DEVELOPING PAYLOAD CONTROLLERS FOR USE BY SPACE SHUTTLE ORBITER CREWS HAS UNVEILED THE CONTINUING AND GROWING PROBLEMS OF NON-STANDARDIZED PROTOCOL AND THE DISTRESS OF CREWS REQUIRED TO LEARN NEW KEYBOARDS AND OPERATING SYSTEMS WITH "EVERY NEW EXPERIMENT". THE KEY TO SOLVING THIS PROBLEM IS TO DEVELOP A HIGH LEVEL LANGUAGE FAMILIAR TO THE ORBITER CREWS INCLUDING SUCH FEATURES AS: (1) ...
