A FEASIBILITY STUDY ON THE DEVELOPMENT OF A STOICHIOMETRIC DIESEL ENGINE IS PROPOSED USING THE THERMAL IGNITION COMBUSTION CHAMBER. THE ADIABATIC DIESEL ENGINE WITHOUT WATER OR AIR COOLING ALLOWS THE THERMAL IGNITION CHAMBER TO STORE HEAT DURING COMBUSTION AND RELEASE THE ENERGY FOR IGNITION IN THE FOLLOWING CYCLE. INJECTION OF FUEL ON TO 1800-2000 DEG. F WALL TEMPERATURE WILL PREPARE THE FUEL FOR ...

A MACHINE TO EVALUATE THE FRICTION AND WEAR PROPERTIES OF MATERIALS AT TEMPERATURES UP TO 1000 DEG C IS PROPOSED. BOTH LUBRICATED AND UNLUBRICATED TESTING WITH LIQUIDS AND SOLIDS WILL BE POSSIBLE USING A PIN-ON-DISC GEOMETRY. COMPLETE CONTROL OVER THE TEST ATMOSPHERE AND MANUAL OR COMPUTER-CONTROL OF ALL VARIABLES WILL BE POSSIBLE DATA ACQUISITION AND STORAGE WILL BE PERFORMED BY COMPUTER. THE TRI ...

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 ...

PRESENT INFRARED DECOYS FOR PROTECTION OF NAVY SHIPS ARE RELIABLE, HIGH INTENSITY COMBUSTION SOURCES. HOWEVER, THEIR EMISSION SPECTRA HAVE CHARACTERISTICS WHICH ALLOW THEM TO BE DISTINGUISHED FROM THE SHIPS THEY ARE INTENDED TO PROTECT. IT IS DESIRABLE TO DEVELOP MODIFIED FUELS WHOSE COMBUSTION WOULD PRODUCE INFRARED SIGNATURES WITH THE APPROPRIATE SPECTRAL PROPERTIES. THIS GOAL REQUIRES A DETAILE ...

AN APPROACH IS BEING INVESTIGATED FOR THE FLUORINATION OF DIAMOND THIN FILMS FOR TRIBOLOGICAL APPLICATIONS. THE APPROACH USES LOW PRESSURES OF F AND/OR CFX FREE RADICALS. TO DEMONSTRATE THE FEASIBILITY OF THIS APPROACH, DATA IS BEING COLLECTED ON: FLUORINATION KINETICS, THE COMPOSITION AND STRUCTURE OF THE SURFACE AND NEAR SURFACE LAYERS, THE EFFECTS OF TEMPERATURE ON THE FLUORINATION PROCESS, AND ...

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 ...

ANALYTIC POWER PROPOSES A SYSTEM ANALYSIS OF THREE POTENTIAL NAVAL AUXILIARY POWER PLANTS USING FUEL CELL TECHNOLOGY. A SYSTEMS ANALYSIS OF THIS APPLICATION IS MANDATORY BECAUSE, MORE OFTEN THAN NOT, THE FUEL CELL IS NOT THE LIMITING TECHNOLOGY. IN MANY CASES, THE FUEL PROCESSOR CAN BE MUCH LARGER THAN THE FUEL TAN AND THE POWER CONDITIONER MAY BE LARGER THAN THE FUEL CELL. CONVENTIONAL COMMERCIAL ...

A CLOSED CYCLE CRYOCOOLER IS BEING INVESTIGATED USING AN APPROACH THAT COMBINES ELECTROCHEMICAL COMPRESSOR AND EJECTOR TECHNOLOGIES. AN ELECTROCHEMICALLY INACTIVE CRYOGEN IS BEING USED IN A UNIQUE TERNARY REFRIGERANT. LIKEOTHER ELECTROCHEMICALLY-DRIVEN REFRIGERATION SYSTEMS UNDER DEVELOPMENT, THIS SYSTEM HAS NO MOVING PARTS. THE SYSTEM ISDESIGNED TO REACH A TEMPERATURE OF 77K, BUT A SIMPLE MODIFIC ...

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 ...

THIS PROJECT WILL DEMONSTRATE THE EFFECTIVENESS OF A NEW APPROACH TO THE TRANSFER OF TECHNOLOGY IN IMAGE UNDERSTANDING (IU). IT IS BASED UPON THE USE OF A SHARED SOFTWARE DEVELOPMENT ENVIRONMENT FOR IU, CALLED THE KBVISION (TM) SYSTEM, WHICH CAN SERVE TO EASE THE TRANSFER OF COMPUTER VISION ALGORITHMS. THE PHASE I PROPOSAL WILL DEMONSTRATE THE FEASIBILITY OF THE TRANSFER OF IU SOFTWARE BY SHARING ...
