SKIN COATINGS FOR IR SIGNATURE SUPPRESSION REQUIRE MORE THAN SIMPLE EMISSIVITY CONTROL. CONTROL OF THE DIRECTIONAL DISTRIBUTION OF EMITTED/REFLECTED RADIATION AND ACTIVE HEATING OR COOLING ARE ALSO NECESSARY. THE RADIANCE FROM THE OBJECT NEEDS TO APPROXIMATE THE RADIANCE FROM THE BACKGROUND OVER A BROAD RANGE OF VIEWING ANGLES. THIS REQUIRES A COMPLICATED BIDIRECTIONAL REFLECTANCE DISTRIBUTION FUN ...

THE ABILITY TO GROW HETEROSPITAXIAL THIN FILMS OF DIAMOND IS LIMITED IN PART BY THE PROPENSITY OF SUCH FILMS TO NUCLEATE AT MULTIPLE SITES WITHOUT PROPER ORIENTATION. WE PROPOSE TO DEVELOP A 2-DIMENSIONAL GROWTH PROCESS BY ATOMIC LAYER EPITAXY (ALE) USING ADVANCED MOLECULAR BEAM TECHNIQUES. THE PHASE I RESEARCH WILL FOCUS ON DETERMINING THE MICROCHEMISTRY OF DEPOSITION PROCESSES AND THUS ALLOW FOR ...

WE PROPOSE TO DEMONSTRATE AN OPTICAL ANALOG-TO-DIGITAL CONVERTER FOR MICROWAVE ANALOG SIGNALS WHICH UTILIZES A SINGLE ELECTROOPTIC BROADBAND VELOCITY MATCHED TRAVELLING WAVE MODULATOR BUT WITH MULTIPLE PULSED OPTICAL BEAMS TO SAMPLE THE SIGNAL AND MULTIPLE STANDARD ELECTRONIC A/D'S TO ACCOMPLISH THE CONVERSION IN PARALLEL. THE DIGITAL OUTPUT WORDS APPEAR ON MULTIPLE SETS OF LINES APPROPRIATE FOR A ...

THE POLARIZATION CHARACTERISTICS OF AIRCRAFT INFRARED SIGNATURES HAVE BEEN STUDIED AS A MEANS TO ENHANCE THE PERFORMANCE OF LONG RANGE PASSIVE INFRARED DETECTION SYSTEMS OPERATING IN THE PRESENCE OF CLUTTER. THESE STUDIES ALSO GENERATED EVIDENCE THAT THE AMOUNT AND ANGLE OF POLARIZATION AS WELL AS ITS SPATIAL DISTRIBUTION ARE UNIQUE BETWEEN DIFFERENT TYPES AND CLASSES OF AIRCRAFT. IT MAY BE POSSIB ...

THE PROPOSED PROGRAM WOULD PROVIDE THE AIR FORCE BALLISTIC SYSTEMS DIVISION (BSD) WITH AN ENGINEERING LEVEL SIGNATURE MODELING CAPABILITY FOR VARIOUS TYPES OF REENTRY VEHICLES (RVS) DURING THE MIDCOURSE PHASE. THE PRESENT AERODYNE RESEARCH, INC. (ARI) SPIRITS SIGNATURE MODEL OFFERS THE BASSIS FOR THE MODELING CAPABILITY IN THE ULTRAVIOLET (UV) THROUGH THE INFRARED (IR) SPECTRUM. THE SPIRITS MODEL ...

MODERN MILITARY OPERATIONS HAVE MADE IT NECESSARY FOR COMMANDERS TO HAVE RADIOLOGICAL INFORMATION CONCERNING NUCLEAR CONTAMINATION OF OCCUPIED AREAS. THIS INCREASING NEED FOR MORE ACCURATE AND RELIABLE INFORMATION FOR THE PURPOSE OF LOCATING AND IDENTIFYING POTENTIALLY HAZARDOUS NUCLEAR SOURCES, HAS LED TO NEED FOR IMPROVED INSTRUMENTATION. IN PARTICULAR, A NUCLEAR SURVEY INSTRUMENT WITH IMAGING C ...

MANY POTENTIAL SPACE SYSTEMS WILL REQUIRE STRUCTURES CAPABLE OF MAINTAINING EXTREMELY TIGHT TOLERANCES ON DIMENSIONS AND VIBRATIONS. ONE APPROACH TO ACHIEVING THE NECESSARY TOLERANCES IS TO EMPLOY TRUSSES MADE USING SMART STRUCTURES. A SMART STRUCTURE IS ONE IN WHICH THE CONTROL, SENSING AND ACTUATION FUNCTIONS ARE INTEGRATED INTO THE MATERIAL WHICH MAKES UP THE INDIVIDUAL TRUSS ELEMENTS. PROPERLY ...

A RARE-EARTH, MAGNETOSTRICTIVE, MATERIAL, TB(X)DY(1-X) (0.50.6), OPERATING AT CRYOGENIC TEMPERATURES, CAN STORE AND RELEASE TWENTY TIMES THE ENERGY OF PIEZOELECTRIC MATERIALS, AND FIVE TIMES THE ENERGY OF THE BEST ROOM-TEMPERATURE, MAGNETOSTRICTIVE, RARE-EARTH ALLOYS. THIS MAKES IT IDEAL FOR THE CONSTRUCTION OF LOW-FREQUENCY, HIGH-POWER, UNDERWATER, ACOUSTIC PROJECTORS. BROAD-BAND, LOW-Q, PROJECTO ...

WE PROPOSE TO DEVELOP A MEMBRANE-BASED EXTRATION PROCESS FOR THE RECOVERY OF ICING INHIBITOR ADDITIVE FROM WATER SEPARATED FROM JP-5 AVIATION TURBINE FUEL; THE TECHNOLOGY WILL ENABLE REBLENDING OF THE ADDITIVIE. THE NOVEL ELEMENT IN THE PROCESS CONSISTS OF A HOLLOWFIBER CROSSFLOW MEMBRANE CONTACTOR TO WHICH AN AQUEOUS FEED SOLUTION OF ANTI-ICING AGENT AND A SUITABLE WATER-IMMISCIBLE EXTRACTION FLU ...

IT IS PROPOSED TO ELUCIDATE ELECTROLYTIC CORROSION IN COOLING SYSTEMS OF THE TYPE EMPLOYED ON NAVY SHIPS FOR HIGH-POWER ELECTRONIC EQUIPMENT. DURING TRANSMISSION, VERY HIGH PULSED DC VOLTAGE DIFFERENCE IS EXPERIENCED BY OPPOSITE METAL HOSE FITTINGS, IN CONTACT WITH DEIONIZED WATER COOLANT. ANOMALOUSLY HIGH RATES OF CORROSION NECESSITATE AN EXPENSIVE FITTING AND HOSE REPLACEMENT PROGRAM. A MAJOR ST ...
