FABRICATION OF ADVANCED COMPOSITES INCLUDES MANY PROCESSES, SOME ARE AUTOMATED, OTHERS ARE ENTIRELY MANUAL. ROBOTIC WINDING SYSTEMS (ROWS) WAS INVENTED BY THE PRINCIPLEINVESTIGATOR IN AN ATTEMPT TO CREATE AN AUTOMATED TECHNIQUE OF LAYING UP PRE-IMPREGNATED MATERIAL AROUND A FORM WITH COMPLEX SHAPE. CONVENTIONAL WINDING EQUIPMENT REQUIRES THE MANDREL TO ROTATE WHILE THE MATERIAL IS DRAGGED ALONG TH ...

N/A

A PROCESS FOR PRODUCING A REAL-TIME CATHODE RAY TUBE (CRT) DISPLAY WITHOUT THE USE OF SPECIAL GLASSES OR DISPLAY CRT ISPROPOSED. THIS SYSTEM WILL INCORPORATE A PROCESS WHICH MAKES INNOVATIVE USE OF ASPECTS OF VISUAL PERCEPTION AND IS IN CURRENT DEVELOPMENT FOR MOTION PICTURES. PHASE I WILL PRODUCE A REAL-TIME DEMONSTRATION OF THE PROCESS ON A COMPUTER-DRIVEN CRT AND MAKE AN OBJECTIVE MEASURE TO SH ...

N/A

THE FEASIBILITY OF BUILDING AN EXTREMELY STABLE, SPECTRALLY NARROW (300 MHZ), AND TUNABLE CW SOLID STATE LASER OPERATINGAT 1.083 MICRON WAVELENGTH REGION USING A SINGLE CRYSTAL OF CHROMIUM DOPED ZINC TUNGSTATE AS THE ACTIVE MEDIUM IS EXAMINED. THE WIDE FLUORESCENCE BANDWIDTH 800-1200 NM OF THIS MATERIAL MAKES IT A PROMISING CANDIDATE FOR NASA SPACE APPLICATION, AS AN OPTICAL PUMPING SOURCE FOR HE3 ...

AN ATTITUDE SENSOR FOR SPINNING OR DUAL SPIN SPACECRAFT IS PROPOSED WHICH PROVIDES FULL SKY (4 PI STERADIAN) COVERAGE PROVIDES 5 INDEPENDENT ATTITUDE MEASUREMENTS IN ADDITION TO ACCURATELY MEASURING THE EARTH'S DIAMETER (WHICH COULD BE OF SUBSTANTIAL VALUE FOR ORBIT DETERMINATION WHEN NEAR THE EARTH.) WE ANTICIPATE AN ATTITUDE ACCRUACY SUBSTANTIALLBETTER THAN 0.1 DEGREES FOR NEARLY ALL SATELLITE O ...

PURPOSE: DETERMINE THE FEASIBILITY OF NEW, LOW COST COMPONENTS FOR 3-AXIS ATTITUDE CONTROL. SUBSYSTEM COST GOALIS $100K. THIS WILL REQUIRE ENGINEERING INNOVATION AND ATTENTION TO MANUFACTURE AND TEST PROCESSES AND, ULTIMATELY,REASONABLE VOLUME. THE ATTITUDE CONTROL ALGORITHMS ARE FLIGHT PROVEN ON HCMM, SAGE, ERBS AND SME. KEY ELEMENTS: AN INNOVATIVE 4-POINT SCANNING HORIZON SENSOR THAT IS ALTITUDE ...

N/A

MANUFACTURING METHOD FOR HIGH ELEVATED-TEMPERATURE STRENGTH FIBERS INCORPORATING RECENT ADVANCES IN SINTERING TECHNOLOGYAND REFRACTORY METAL ALLOY DEVELOPMENT WILL BE INVESTIGATED.A CONTROLLED ATMOSPHERE SINTERING OF POWDER METALLURGY INGOTS OF NEW MOLYBDENUM AND TUNGSTEN ALLOYS UNDER A SELECTED CHEMICAL POTENTIAL ENVIRONMENT, IN CONJUCTION WITH SUBSEQUENT OPTIMIZED WIRE DRAWING PROCESS MAY PRODUC ...

MODERN AVIATION REQUIRES ALL-WEATHER CAPABILITY. ONE OF THEMAJOR PROBLEMS INVOLVES THE RELIABLE DETECTION OF ICE FORMATION ON WINGS, ENGINES AND ROTORS, AS WELL AS ON AIRCRAFT RUNWAYS. AT PRESENT, NO SYSTEM HAS BEEN DEVELOPED WHICH POSITIVELY DETECTS ICE PER SE, AND NOT MERELY POTENTIAL ICING CONDITIONS. OUR PROPOSAL IS TO DEVELOP A DEVICE WHICH WILL NOT AFFECT THE AERODYNAMIC PROPERTIES OF WINGS, ...
