ORDNANCE RECLAMATION ACTIVITIES RESULT IN A SURPLUS OF PLASTIC BONDED EXPLOSIVES (PBXS). AS CURRENTLY FORMULATED, THESE MATERIALS ARE TOO ENERGETIC FOR COMMERCIAL BLASTING APPLICATIONS. PBXS COULD BE MODIFIED THROUGH THE USE OF LOW DENSITY FILLERS TO GENERATE APPROPRIATE EXPLOSIVE CHARACTERISTICS. SUCH MATERIALS COULD REDUCE DRILLING REQUIREMENTS FOR BLASTIN PURPOSES, THUS, ACHIEVING COST SAVINGS. ...

THE OBJECTIVE OF THIS PROGRAM IS TO DEVELOP A COMPACT, RUGGED, TWELVE-CHANNEL (MINIMUM) DIGITAL DATA ACQUISITION SYSTEM CAPABLE OF MEASURING AND RECORDING SHOCK EXPERIENCES ASSOCIATED WITH WEAPON DELIVERY AND USE. THE SYSTEM MAY BE MODULAR, BUT EACH MODULE MUST CONTAIN FOUR DATA CHANNELS AND BE NO LONGER THAN 2.5 INCHES MAXIMUM DIMENSION. MECHANICAL DESIGN OF THE SYSTEM MUST BE SUCH THAT IT WILL O ...

THE PROPOSED RESEARCH WILL INCORPORATE THE PARAMETRIC AVALANCHE NEURAL NETWORK ARCHITECTURE INTO A MAXIMUM LIKELIHOOD DETECTION AND TRACKING ALGORITHM FOR USE IN AUTONOMOUS WEAPON SYSTEMS. THE PARAMETRIC AVALANCHE WILL PERFORM O(1) SEARCH IN ITS STORED PATTERN FEATURES TO IDENTIFY THE TARGET AND ITS MOTION EQUATIONS, AFTER WHICH IT WILL TRACK THE TARGET. A SECOND PARAMETRIC AVALANCH WILL USE THE S ...

A ROBOTIC POSITIONER WILL BE DEVELOPED FOR HANDLING AND CHANGING DEVICES TO BE TESTED (DUTS) IN HAZARDOUS RADIATION ENVIRONMENTS SUCH AS THAT FOUND INSIDE THE TEST CELL OF THE BROOKHAVEN NATION LABORATORY PROTON ACCELERATOR. PRESENTLY, PERSONNEL SAFETY INDICATES A LONG "COOLING" TIME BEFORE TEST FIXTURES CAN BE ACCESSED. THIS RESULTS IN LOWERED FACILITY USEFULNESS, INCREASED REAL FACILITY COSTS AN ...

A TEST INSTRUMENTATION SYSTEM IS PROPOSED FOR THE DETECTION AND ISOLATION OF UPSET FAULTS PRODUCED BY TRANSIENT RADIATION IN VHSIC CLASS ASICS AND GENERAL PURPOSE MICROCIRCUITS. THE PROPOSED SYSTEM IS COMPOSED OF A HIGH SPEED WORK STATION, A PORTABLETESTER, AND A SEPARABLE TEST HEAD CONTAINING THE DEVICE UNDER TEST TO BE PLACED IN THE RADIATIONN BEAM. THE WORK STATION ACTS AS A CONTROLLER FOR THE ...

WOOD AND RESIN MATRIX COMPOSITE PROPELLERS FOR UNMANNED AIR VEHICLES SUFFER UNACCEPTABLE EROSION DAMAGE DUE TO LIQUID AND SOLID IMPACT. POLYMERIC PROTECTIVE COATINGS ARE INEFFECTIVE IN SOLID PARTICLE ENVIRONMENTS. THE BROAD DAMAGE AREA OF PROPELLERS MAKES METALLIC PROTECTIVE COATINGS, SUCH AS HAVE BEEN DEVELOPED FOR HELICOPTER BLADES, UNACCEPTABLE FROM A WEIGHT PENALTY. CONVENTIONAL CERAMIC COATIN ...

HIGH-VALUE TEST ITEMS ARE OFTEN LOST IN OPEN-OCEAN TEST AND PRACTICE RANGES. SUCH ITEMS INCLUDE WEAPONS, FLIGHT DATA RECORDERS, MISSILES, DRONES, AND MANNED TACTICAL AIRCRAFT. THE LOSS OF VALUABLE TEST DATA CAN BE A SERIOUS PROBLEM. IN ADDITION, RECOVERY OF SOME ITEMS BY FOREIGN GOVERNMENTS NOT ONLY COMPROMISES WEAPON TECHNOLOGY, BUT CAN RENDER AN ENTIRE WEAPON SYSTEM SUSCEPTIABLE TO FOREIGN COUNT ...

DEVELOPMENT OF REACTIVE PRIMER/MODIFIED PHENOLIC ADHESIVE SYSTEM IS PROPOSED FOR BONDING RADOME MATERIALS. INITIAL STUDIES HAVE SHOWN THAT THE REACTIVE PRIMER CHEMISTRY WILL FORM CHEMICAL BONDS WITH METALS, CERAMICS AND POLYMERS. A TWO-STAGE PRIMER IS PROPOSED THAT CAN BE BONDED TO A RADOME SUBSTRATE AND AN ADHESIVE IN TWO SEPARATE OPERATIONS, EITHER BY TEMPERATURE, ACTINIC LIGHT OR A COMBINATION ...

A SERIES OF WELL CHARACTERIZED IM6/3501-6 COMPOSITE PLATES WILL BE EXPOSED TO CONTROLLED, WILL INSTRUMENTED JP4 POOL FIRES OF VARYING DURATION. FIRE EXPOSED PLATES WILL BE CHARACTERIZED USING PULSE-ECHO ULTRASONIC, MICROSCOPY, DSC, TAG AND MECHANICAL TESTING IN FLEXURE AND SHORT BEAM SHEAR. TEMPERATURE AND HEAT FLUX DATA COMBINED WITH COMPOSITE CHARACTERIZATION RESULTS WILL BE USED TO DETERMINE OP ...
