THIS PROPOSAL DESCRIBES A FEASIBILITY STUDY FOR IMPLEMENTING A REALTIME, THREE-DIMENSIONAL CLOUD MODEL TO SUPPORT REENTRY VEHICLE TEST OPERATIONS. AN EXISTING RESEARCH CLOUD MODEL WOULD BE INTERFACED TO A MESOSCALE ATMOSPHERIC MODEL. THE COMBINED MODELING SYSTEM WOULD BE ADAPTED FOR USE AT THE KWAJALEIN MISSILE RANGE (KMR). FORECASTS OF DETAILED CLOUD FEATURES SUCH AS WATER CONTENT, RADAR REFLECTI ...

A PLAN FOR THE DEVELOPMENT OF A MESOSCALE WEATHER NOWCASTING SYSTEM IS PROPOSED. THAT SYSTEM WOULD BE USED AS A TACTICAL DECISION AID FOR SUPPORT OF TACTICAL ARMY OPERATIONS. THE SYSTEM WOULD BE COMPOSED OF MODULAR SENSOR PACKAGES, A TELEMETRY SYSTEM, A FLEXIBLE SYSTEM OF SENSOR DEPLOYMENT, AND A MICROPROCESSOR BASED TACTICAL COMPUTER SYSTEM FOR THE ANALYSIS AND DISPLAY OF DATA COLLECTED. THE PROP ...

THIS RESEARCH WILL INVESTIGATE PERFORMANCE MEAUREMENT TECHNIQUES AND COMPUTER SIMULATION TECHNIQUES REQUIRED FOR AN ON-BOARD AIRCRAFT "EMBEDDED TRAINING" CAPABILITY APPLICABLE TO BOTH TRAINING AND MUNITION CONCEPT EVALUATION. DATA REQUIREMENTS FOR ON-BOARD SIMULATION OF THE MUNITIONS TO ACCOMPLISH SIMULATED LAUNCH, FLYOUT AND TERMINAL ENGAGEMENT WILL BE DETERMINED. AVAILABILITY OF REAL-WORLD INPUT ...

CONTRACTOR WILL DEVELOP A LAGRANGIAN FORMULATION FOR THE ELECTROMAGNETIC RESPONSE OF A METALLIC ENCLOSURE WITH THIN, SLIGHTLY DIFFUSIVE WALLS AND A WIRE SPANNING THE ENCLOSURE. CONTRACTOR WILL FIRST DERIVE A LAGRANGIAN OPERATOR ON THE FIELDS WHICH IS STATIONARY WHEN MAXWELL'S EQUATIONS ARE SATISFIED. THE LAGRANGIAN WILL THEN BE USED TO DETERMINE THE ENCLOSURE EIGENMODES (WIRE INCLUDED) AND THE AMP ...

CODES CURRENTLY EXIST THAT WILL CALCULATE THE ELECTROMAGNETIC ENVIRONMENT (EMP) PRODUCED BY A BEAM OF COLLIMATED GAMMA RAYS. THE COLLIMATION MAY BE EITHER CYLINDRICAL OR CONICAL. THE CURRENT EFFORT WILL BE TO INSTALL THE CODES ON AN ARMY CRAY COMPUTER AND TO SET THEM UP AND RUN THEM FOR PROBLEMS OF INTEREST TO THE ARMY.

THERE IS AN ESTABLISHED NEED FOR A SIMPLE ROBUST TRANSDUCER TO MEASURE PARTICLE VELOCITY IN SEVERE BLAST AND SHOCK ENVIRONMENTS SUCH AS NUCLEAR AND HIGH EXPLOSIVE TESTS. A GAGE CONCEPT IS PROPOSED FOR DEVELOPMENT, BASED ON THE PROVEN MEASUREMENT PRINCIPLES USED IN THE HIGHLY SUCCESSFUL DX GAGE, BUT RECONFIGURED MECHANICALLY AND ELECTRICALLY TO WITHSTAND THE HARSH SHOCK ENVIRONMENTS. THE CONCEPT RE ...

THE PROPOSED EFFORT IS TO DEVELOP MATERIALS AND PROCEDURES TO APPLY REECH-FROUDE SCALING TO SUB-SCALE MODEL TESTS OF REINFORCED CONCRETE STRUCTURES SUBJECTED TO CONVENTIONAL (NON-NUCLEAR) WEAPON EFFECTS.

THE COMBINED REQUIREMENTS FOR HIGH SPATIAL RESOLUTION AND HIGH SIGNAL-TO-NOISE RATIO HAVE LED MANY RECENT TRACKING SYSTEMS ANALYSTS TO CONSIDERACTIVE TRACKERS IMPLEMENTED WITH PHASED ARRAY OPTICS. THE PHASED ARRAY OVERCOMES THE TECHNOLOGY LIMITS ON APERTURE SIZE WHILE THE LASER SOURCES PROVIDE A DETECTABLE TARGET RETURN. THE PHASED ARRAY IMAGER HAS BEEN MODELLED FOR BOTH NON-COHERENT AND FULLY COH ...

ULTRASONIC NONDESTRUCTIVE TESTING HAS BECOME THE METHOD OF CHOICE FOR THE QUALITY ASSURANCE OF ADVANCED COMPOSITE MATERIALS. THE PROPOSED RESEARCH PROGRAM COVERS THE DEVELOPMENT OF A COMPUTER-BASED NDT METHOD FOR DETERMINING LOCAL FIBER VOLUME FRACTION AND RESIN POROSITY IN PRACTICAL LAMINATED COMPOSITES. THE COMPUTER ALGORITHMS WILL BE BASED ON EARLIER STUDIES THAT HAVE BEEN SUCCESSFUL FOR UNIDIR ...
