NEW COMMAND AND CONTROL SYSTEMS CONSIST OF COMPLEX NETWORKS OF DISTRIBUTED PROCESSING ELEMENTS, WORKSTATIONS, AND DATA BASES. MANY OF THESE SYSTEMS, SUCH AS WIS, USAFE INCOMNET, AND MAC GDSS HAVE IDENTIFIED REQUIREMENTS FOR A MLS/TRUSTED GATEWAY INTERFACE DEVICE TO PROVIDE AUTOMATED INTERCONNECTION TO SYSTEMS AT OTHER SECURITY LEVELS.THE DDN SECURITY ARCHITECTURE HAS IDENTIFIED A SIMILAR REQUIREME ...

THE DIRAD TEAM HAS IDENTIFIED A DIGITALLY IMPLEMENTED RECEIVER ARCHITECTURE THAT PROVIDES UNIQUE PERFORMANCE CAPABILITIES PRESENTLY UNATTAINABLE IN CONVENTIONAL ANALOG RECEIVER IMPLEMENTATIONS; BANDPASS FILTER CHARACTERISTICS, WIDEBAND AGC OPERATION, NOISE REDUCTION/ ADAPTABILITY, MULTIPLE INTEGRATED CONFIGURATIONS, IMPROVED A/J PERFORMANCE, AND GREATLY REDUCED ILS POTENTIAL ARE INCLUDED. THIS PRO ...

THE USE OF GRAPHITE/MAGNESIUM COMPOSITES FOR SPACE STRUCTURES WITH ZERO THERMAL EXPANSION CHARACTERISTICS HAS BEEN HAMPERED BY THE HYSTERESIS CAUSED BY MATRIX YIELDING. THIS HYSTERESIS HAS BEEN ELIMINATED IN LABORATORY SAMPLES BY HEAT TREATING THE COMPOSITE TO OBTAIN A MATRIX YIELD STRENGTH IN EXCESS OF 40 KSI FOR ALUMINUM MATRIX COMPOSITES. THE REQUIRED HEAT TREATMENT WILL BE IMPRACTICAL WHEN LAR ...

THE OBJECTIVE OF THE PROPOSED RESEARCH IS TO DEVELOP CONCEPTS AND PROCEDURES WHICH CAN COMPENSATE FOR GRAVITY EFFECTS (WITHOUT USING ARTIFICIALLY-INDUCED GRAVITY) IN SMALL SCALE ONE-G MODEL TESTS SIMULATING THE EFFECTS OF CLOSE-IN AND SHALLOWLY BURIED DETONATION OF NONNUCLEAR WEAPONS ON PROTECTIVE STRUCTURES. THE SUCCESS OF THIS PROPOSED PROGRAM WILL LEAD TO THE IMPROVED DESIGN/UPGRADE METHODOLOGI ...

"RECENT TECHNOLOGICAL ADVANCES HAVE ASSURED THE POSSIBILITY OF RADICALLY EXPANDING THE MANEUVERING ENVELOP OF FUTURE FIGHTER DESIGNS. INCREASES IN FORCE AND MOMENT GENERATION AS WELL AS ENHANCED DEPARTURE RESISTANCE WILL ENABLE THE NEXT GENERATION OF FIGHTERS TO PERFORM MANEUVERS BEYOND TODAY'S CONVENTIONAL FLIGHT BOUNDARIES. WHILE THE FEASIBILITY OF SUCH MANEUVERS, REFERRED TO AS SUPERMANEUVERS, ...

MODERN FIGHTER AIRCRAFT ARE OPERATING IN A FLIGHT REGIME WITH INCREASING DEMANDS FOR MANEUVERABILITY AND CONTROLLABILITY TO BE EFFECTIVE IN THE COMBAT ARENA. ONE OF THE LIMITATIONS TO THAT EFFECTIVENESS IS THE INABILITY TO ACCURATELY TRACK TARGETS FOR GUN OR MISSILE SHOTS DUE TO THE DEGRADING CHARACTERISTICS OF WING ROCK. WING ROCK IS A SELF-INDUCED, LIMIT-CYCLE OSCILLATION IN ROLL, SOMETIMES ACCO ...

INCIDENTS OF G-INDUCED LOSS OF CONSCIOUSNESS (G-LOC) OCCUR WITH ALARMING FREQUENCY IN TODAY'S HIGH PERFORMANCE TACTICAL AIRCRAFT AND POSE A SIGNIFICANT HAZARD TO FLIGHT SAFETY. IT IS CLEAR THAT THE NUMBER OF G-LOC RELATED MISHAPS NOW OCCURING IN THE PEACE-TIME TRAINING ENVIRONMENT IS ONLY A FRACTION OF WHAT MIGHT BE EXPECTED IN COMBAT OR WITH ADVANCED FIGHTERS WITH IMPROVED MANEUVERING PERFORMANCE ...

THE DEVELOPMENT OF THE SILICON RESISTOR ARRAY TECHNOLOGY HAS BEEN PROPOSED TO FABRICATE AN IR (INFRARED) AIR TARGET SIMULATOR SPECIFICALLY FOR SIMULATING, TESTING AND MODELING OF SEEKER-TO-TARGET RANGE CLOSURE CONDITIONS. EACH RESISTOR HEATED BY A PASSAGE OF CURRENT ACTS AS A BLACKBODY RADIATOR, AND THIS CURRENT IS INDIVIDUALLY CONTROLLED BY A MOS (METAL-OXIDE-SEMICONDUCTOR) CIRCUIT (ONE OF EACH R ...
