THIS PROJECT WILL PREPARE FOR EVALUATION A MATERIAL WHICH SHOULD DEMONSTRATE SUPERIOR PERFORMANCE IN ABSORBING AND DISSIPATING EXPLOSION SHOCK ENERGY. THE COMPOSITION PROPOSED AND ITS BASIS FOR PERFORMANCE ARE EXPLAINED. SHOCK WAVE TESTING WILL BE UNDERTAKEN; AND BASED ON THE RESULTS, RECOMMENDATIONS WILL BE MADE FOR FUTURE PROJECT DIRECTION.

THE OBJECTIVES OF THE PROPOSAL EFFORT ARE TO IMPROVE THE RELIABILITY AND TO REDUCE THE FABRICATION COSTS OF SINGLE MODE FIBEROPTICS COUPLERS BY: 1. DEVELOPING THICK, SINGLE MODE WAVEGUIDES WITH IDENTICAL CROSS SECTIONAL PROFILE MATCHING THAT OF SINGLE MODE FIBERS; AND 2. LOCATING THESE FIBERS TO WAVEGUIDES, MADE OF ELECTROOPTIC MATERIAL, USING PREALIGNED ETCHED "V" GROOVES IN A GAAS SUBSTRATE. OUR ...

THE NAVY DESIRES TO ELIMINATE GASOLINE TO FUEL REMOTELY PILOTED VEHICLES BECAUSE OF GASOLINE'S LOW FLASH POINT AND RELATIVE UNAVAILABILITY ABOARD SHIPS. THE NAVY REQUIRES ENGINES IN THE 25 TO 35 BHP RANGE, WEIGHING LESS THAN 20 POUNDS, THAT ARE FUELED BY JP-5 AND/OR DIESEL FUEL, THAT WILL START AND OPERATE RELIABLY AT -40 DEG. F AND THAT HAVE REASONABLE FUEL CONSUMPTION CHARACTERISTICS UNDER BOTH ...

FUTURE MILITARY AVIONICS SYSTEMS WILL BE DEPENDING MORE ON BUILT-INTEST (BIT) FOR FAULT DETECTION AND ISOLATION TO MEET STRINGENT RELIABILITY, MAINTAINABILITY, AND SUPPORTABILITY GOALS. RECENT EXPERIENCE INDICATES THAT BIT IS NOT MEETING SPECIFICATION REQUIREMENTS IN FIELD OPERATIONS, EXHIBITS A HIGH FALSE ALARM RATE, HAS LOW RELIABILITY, AND IS UNABLE TO ISOLATE FAILURES TO A SINGLE MODULE. AS A ...

THE COMPLEXITY OF THE NEXT-GENERATION FAULT-TOLERANT ELECTRONIC SYSTEM DESIGN TASKS WILL REQUIRE INTERACTIVE ACCESS TO THE RELIABILITYPREDICTION TOOLS IN ORDER TO ACHIEVE THE DESIRED RELIABILITY GOALS. THIS PROPOSAL ADDRESSES THE INTEGRATION OF THE AFHRL DEVELOPED MISSION RELIABILITY MODEL (MIREM) AND THE AVAILABLE CIRCUIT DESIGN PROGRAMS IN AN ENGINEERING WORKSTATION ENVIRONMENT. THE PROPOSED EFF ...

CURRENTLY AVAILABLE AUTHORING SYSTEMS HAVE BEEN PROVEN EFFECTIVE IN PRODUCING COMPUTER-BASED TRAINING LESSONS CONTAINING SEQUENCES OF TEXT AND GRAPHICS SCREENS THROUGH WHICH THE STUDENT IS GUIDED UNTIL MASTERY IS ACHIEVED. IN A PERSONNEL TRAINING SIMULATION, FAR MORE ADVANCED CAPABILITIES ARE REQUIRED, INCLUDING MULTITASKING, COMMUNICATION WITH EXTERNAL DEVICES, HIGH SPEED DATA ANALYSIS AND GRAPHI ...

THE PURPOSE OF THE PROPOSED RESEARCH IS TO EXPLORE THE WORTHINESS OF EMPLOYING REACTIVE PROTECTION FOR STRUCTURES SUBJECTED TO THE EFFECTS OF MODERN CONVENTIONAL WEAPONS. THE REACTIVE PROTECTION CONSISTS OF HIGH EXPLOSIVE (HE) CHARGES EMBEDDED IN PROTECTIVE LAYERS. THE SYSTEM IS INTENDED FOR DISTRUBING THE PENETRATION CAPABILITIES OF MODERN CONVENTIONAL WEAPONS, CONTROLLING THE MAGNITUDE OF LOADS ...
