A DYNAMIC ATTRIBUTE SPECIFICATION AND ATTACHMENT KIT (DASAK) IS PROPOSED TO SERVE AS A SUPPORT COMPONENT FOR THE RAPIDLY RECONFIGURABLE CREWSTATION (RRC) PROGRAM. A DASAK WILL PROVIDE A USERFRIENDLY INTERFACE TO COCKPIT DESIGNERS WITHOUT PROGRAMMING EXPERIENCE FOR DEFINING DYNAMIC ATTRIBUTES AND ATTACHING THEM TO GRAPHIC OBJECTS, SUCH AS TARGET AIRCRAFT, WEAPONS, ETC., WHICH ARE FOUND IN COCKPIT D ...

COMPUTED TOMOGRAPHY (CT) IS RAPIDLY BECOMING AN IMPORTANT COMPLEMENT TO OTHER NON-DESTRUCTIVE EVALUATION (NDE) METHODS AND IS THE PREFERRED NDE TECHNIQUE WHENEVER THE PRIMARY GOAL IS TO LOCATE AND SIZE PLANAR AND VOLUMETRIC DETAIL IN THREE DIMENSIONS. HOWEVER, MODERN MILITARY CT SYSTEMS ARE CAPABLE OF GENERATING MORE THAN A GIGABYTE OF CT INSPECTION DATA PER DAY--AND EVEN HIGHER DATA RATES CAN BE ...

THE DEVELOPMENT OF ANALOG DEVICES FABRICATED ON DEFECT-FREE ADVANCED SUBSTRATES WITH INCREASED NEUTRON TOLERANCE IS PROPOSED. THIS CONCEPT WILL IMPLEMENT ULTRA-THIN, DEFECT-FREE, SILICON-ON-INSULATOR SUBSTRATES FABRICATED BY BONDING AND ETCH BACK (BESOI) TO DEMONSTRATE LATERAL BIPOLAR DEVICES WITH EXTREMELY LOW BASE RESISTANCE AND RECOMBINATION VOLUME. DEVICES WITH A CUT-OFF FREQUENCY IN EXCESS OF ...

THERE IS A NEED FOR A PORTABLE DETECTOR SYSTEM THAT CAN DETECT ILLEGAL DRUGS, PRIMARILY MARIJUANA, COCAINE, AND HEROIN, ENTERING THE UNITED STATES ABOARD MARITIME VESSELS. A PRELIMINARY INVESTIGATION HAS SHOWN THAT SAW TECHNOLOGY CAN DETECT 10 FEMTOGRAMS (1 X 10-14) WITH A SIGNAL TO NOISE RATIO OF 3:1. IN ADDITION, THESE SENSORS HAVE A DYNAMIC RANGE OF OVER 1,000,000. BY COMBINING SAW TECHNOLOGY W ...

A NOVEL HIGH POWER MILLIMETER/MICROWAVE SOURCE IS PROPOSED IN WHICH TWO INTERPENETRATING STREAMS OF ELECTRONS, FLOWING THROUGH A BACKGROUND PLASMA IN A STATIC MAGNETIC FIELD ARE USED TO GENERATE A HOT-ELECTRON PLASMA THAT IS CONFINED IN A MIRROR-LIKE MAGNETIC FIELD IN THE FORM OF A FOLDED-CUSP MAGNETIC CONFIGURATION. ENERGY STORED IN THE ANISOTROPIC, HOT-ELECTRON PLASMA IS THEN USED TO AMPLIFY UNS ...

THE OBJECTIVE OF THE PROPOSED WORK IS TO ANALYZE THE HYPERVELOCITY MODELS TESTED AT ARNOLD ENGINEERING DEVELOPMENT CENTER TO DETERMINE THE CAUSE OF NOSETIP FRACTURES. WE WILL ACCOMPLISH THIS GOAL BY PERFORMING TWOAND THREE-DIMENSIONAL FINITE ELEMENT ANALYSES OF THE HYPERVELOCITY MODEL USING DYNA2D AND DYNA3D. IF NECESSARY, WE WILL ALSO DO HYDRODYNAMIC ANALYSES OF THE GAS EXPANSION WHICH DRIVES THE ...

THE FEASIBILITY OF USING AERODYNAMIC HEATING LOADS ON THE HPJ JAMMER BODY TO ACTIVATE A HIGH POWER MINIATURE BATTERY WILL BE INVESTIGATED. A MOLTEN ELECTROLYTE BATTERY OF NOVEL DESIGN APPEARS CAPABLE OF ACHIEVING MORE THAN TWICE THE VOLUMETRIC POWER DENSITY REQUIRED BY THE JAMMER AND ROUGHLY 50 TO 100 TIMES THE POWER DENSITY OF SMALL LITHIUM LIQUID-ELECTROLYTE CELLS. AUTOMATIC BATTERY ACTIVATION A ...

DATA FROM RECOVERED ROCKET MOTORS HAS CONVINCINGLY SHOWN THAT MORE CHARRING/EROSION OCCURS ON FORWARD DOME INSULATION DURING FLIGHT THAN IN STATIC FIRING. THE PROBLEM OF FLIGHT AMPLIFICATION OF CHARRING/EROSION HAS GREATLY INCREASED TO COMPLEXITY OF THE DESIGN PROCESS FOR FUTURE ROCKET MOTORS, ESPECIALLY THOSE SUBJECTED TO HIGH ACCELERATION. LARGE SAFETY FACTORSMUST OFTEN BE APPLIED RESULTING IN T ...

THE DEFICIENCIES IN CURRENT ANTENNA WINDOW MATERIALS AND DESIGN METHODS RESTRICT THE PERFORMANCE GOALS OF CERTAIN ADVANCED AIR FORCE SYSTEMS. TO IMPROVE THE PERFORMANCE AND/OR EXPERIMENTAL EVALUATION OF ANTENNA WINDOWS AND THEREFORE IMPROVE OVERALL SYSTEM EFFECTIVENESS; MATERIAL FORMULATIONS, MATERIAL CONSTRUCTIONS, DESIGN METHODS AND TEST FACILITY IMPROVEMENTS WILL BE EVALUATED. THIS STUDY WILL I ...

TRANSPIRATION COOLED NOSETIPS (TCNTS) FOR ICBM REENTRY VEHICLES OFFER SHAPE STABILITY, ENHANCED THERMAL/EROSION PERFORMANCE AND POTENTIAL DESIGN SOLUTIONS FOR HIGH STRENGTH AND SMALL RADIUS NOSETIPS. CURRENT TCNT DESIGN AND FABRICATION PROCESSES ARE TIME-CONSUMING AND EXPENSIVE, HAMPERING RESEARCH EFFORTS AND INHIBITING APPLICATION OF TCNTS TO REENTRY SYSTEMS. ADVANCED DESIGN AND FABRICATION METHO ...
