RAPID INTENSE HEATING OF COMPOSITE LAMINATES DUE TO DIRECT ENERGY WEAPONS WILL INDUCE STRONG THERMAL GRADIENTS THAT IN TURN PRODUCE DYNAMIC STRESSES IN THE FORM OF WAVE MOTION. THE OBJECTIVE OF THIS RESEARCH IS TO DEVELOP A MINDLIN PLATE FINITE ELEMENT PROGRAM FOR ANALYSIS OF THE DYNAMIC BEHAVIOR IN A COMPOSITE LAMINATE SUBJECTED TO COMBINED THERMAL/SHOCK AND SIMULATED IN-FLIGHT AERODYNAMIC LOADIN ...

THIS PHASE I SBIR PROGRAM PROPOSES TO DETERMINE THE FEASIBILITY OF USING HIGH-RESOLUTION DIGITAL RADIOGRAPHY (DR), LAMINOGRAPHY, AND COMPUTED TOMOGRAPHY (CT) TO EXAMINE LAMINAR BONDS IN COMPOSITE SAMPLES SUPPLIED BY THE ARMY. THE PROJECT WILL UTILIZE DISCRETE, SOLID-STATE X-RAY DETECTORS DESIGNED AND BUILT BY BIO-IMAGING RESEARCH, INC. THE PHASE I PROGRAM WILL ALSO RECOMMEND A PRELIMINARY DESIGN F ...

THE AUDIO-VISUAL INITIAL DEBUG (AVID) METHOD IS PROSPOSED ASA FIRST- LINE SOFTWARE DEVELOPMENT TOOL FOR LOCATING ERRORS IN NEW SOURCE CODE. THE CONCEPT INVOLVES USING A COMPUTERR SPEECH SYNTHESIZER CONNECTED TO THE TERMINAL TO PROVIDE AN AUDIO PLAY-BACK OF THE SOURCE CODE WHILE AS CURRENTLY ENVISIONED IS SPECIFICALLY DESIGNED TO ANALYZE AND SPEAK COMPUTER LANGUAGE. CERTAIN STANDARD AND USER-DEFINE ...

THE DESIGN AND CONSTRUCTION OF A LARGE SCALE SOIL LABORATORY FACILITY CAPABLE OF IMPOSING AXISYMMETRIC STRESSES UP TO 1,000 PSI ON CYLINDRICAL SOIL SPECIMENS AS LARGE AS THREE METERS IN DIAMETER IS PROPOSED. THE OPTION OF PHASED CONSTRUCTION OF A 1-1/2 METER DIAMETER, FOLLOWED BY CONSTRUCTION OF A THREE METER DIAMETER FACILITY IS OFFERED. THE DESIGN WILL INCLUDE ALL ANCILLARY SPECIAL EQUIPMENT TO ...

VARIOUS RADAR AND TARGET SEEKER SYSTEMS ARE BEING DEVELOPED TO OPERATE AT MILLIMETER SYSTEMS. LOW COST, HIGHLY RELIABLE FRONT END HARDWARE IS REQUIRED FOR THESE MUNITIONS. DIELECTRIC INSULAR WAVEGUIDE PLANAR INTEGRATED CIRCUITS FOR THIS PURPOSE WERE DESCRIBED INITIALLY BY EPSILON LAMBDA PERSONNEL IN 1970. SOME OF THESE RADARS ARE OF THE FM-CW TYPE, AND THIS PROPOSAL ADDRESSES THE NEED FOR DEMONSTR ...

CURRENTLY A PRIMARY DRAWBACK OF FIBER OPTIC SYSTEMS FOR MILITARY USE IS THE DIFFICULTY OF REPAIRING AND SERVICING THESE SYSTEMS. THE OBJECTIVE OF THIS PROJECT WILL BE TO DEVELOP TECHNIQUES FOR RAPID, RELIABLE FIELD REPAIR OF FIBER OPTIC CONNECTORS AND CABLES, TO PUT MAINTENANCE OF THESE SYSTEMS ON PAR WITH COPPER WIRE INTERCONNECTIONS.TECHNIQUES FOR RELIABLE HIGH PERFORMANCE TERMINATION OF GLASS F ...

A TECHNIQUE IS PROPOSED WHEREBY THE BORESIGHT ALIGNMENT BETWEEN A HELICOPTER MISSILE OR ROCKET LAUNCH SUPPORT STRUCTURE AND THE REFERENCE SYSTEM CAN BED DETERMINED IN THREE AXES. THE TECHNIQUE EMPLOYS NEWLY-DEVELOPED FAST SCANNING ELECTRO-OPTICAL SENSORS AND FAST SPECIALMICROPROCESSOR SUBSYSTEMS. THE WORKPLAN INCLUDES DESIGN AND EVALUATION OF THE APPROPRIATE ALGORITHMS, SCALED EXPERIMENTS USING A ...
