TAC PROPOSES TO CONDUCT A STUDY TO EVALUATE THE COMPARATIVE EFFECTIVENESS OF VARIOUS FORWARD-LOOKING AUTONOMOUS SENSORS AND ALGORITHMS FOR TLAM-C. THE CURRENT TLAM-C USES A TERRAIN MAPPING RADAR ALTIMETER AND CORRELATES THE SENSED AREA AT KEY WAYPOINTS WITH A STORED DIGITAL REPRESENTATION OF THE TERRAIN AREA AT THE WAYPOINTS TO PROVIDE MID-COURSE AND TERMINAL GUIDANCE CORRECTION TO THE INERTIAL NA ...

IMPROVED PERFORMANCE OF TONPILZ-TYPE TRANSDUCER ELEMENTS CAN RESULT FROM (1) INCREASING THE AREA OF THE RADIATING FACE AND (2) DECREASING THE MASS OF THE RADIATING HEAD. HOWEVER, SUCH IMPROVEMENT IS LIMITED BY THE INTRODUCTION OF A FLEXURE MODE, WITH THE OUTER RING MOVING AT A DIFFERENT VELOCITY AND PHASE FROM THE INNER AREA OF THE HEAD-MASS. THE UNDESIRABLE RESULT IS A BI-MODAL RESPONSE WITH, GEN ...

THIS PROPOSAL ENVISIONS DETERMINING THE FEASIBILITY OF USING PHOTOFABRICATION TECHNOLOGY TO PRODUCE LOW COST SEAWATER CORROSION SENSORS. UNLIKE CONVENTIONAL ELECTROCHEMICAL CORROSION SENSORS WHICH MEASURE ONLY INSTANTANEOUS CORROSION RATE, THE PROPOSED SENSORS WILL MEASURE BOTH INSTANTANEOUS RATE AND CUMULATIVE CORROSION. THE TENTATIVE DESIGN OF THESE SENSORS IS VERY COMPACT, ABOUT THE SIZE OF A P ...

A PROPOSAL IS PRESENTED HEREIN TO DEVELOP A NUMERICAL PROCEDURE FOR ANALYZING THE SHIP NUMERICAL PROCEDURE FOR ANALYZING THE SHIP PROPELLER TIP VORTEX PROBLEM. THE FLOW IN THIS REGION IS VERY COMPLEX AS IT CONTAINS THREE-DIMENSIONAL, VISCOUS AND CENTRIFUGAL EFFECTS. THE LONG TERMS GOAL OF THE PROPOSED EFFORT WOULD DEVELOP A COMPREHENSIVE PREDICTIVE PROCEDURE FOR THE SHIP PROPELLER TIP REGION WITH ...

METHYLENE BIS O-CHLORO ANILINE HAS LONG BEEN RECOGNIZED AS A SUPERIOR URETHANE CURATIVE BUT TOXICITY CONCERNS HAVE LIMITED ITS USE. ALTERNATIVE COMPOUNDS ARE AVAILABLE, BUT THEY CANNOT MATCH THE HANDLING AND ULTIMATE PHYSICAL PROPERTIES OF MOCA CURED ELASTOMERS. AN INVESTIGATIONS OF NOVEL PLYAMINE AND POLYOL COMPOUNDS SHOULD YIELD NEW AND USEFUL URETHANE CURATIVES. THE PROGRAM WOULD IN VOLVE SCREE ...

FLAME RETARDANT FLEXIBLE POLYURETHANE FOAM FINDS WIDESPREAD COMMERCIAL USE AS A SEATING MATERIAL DUE TO ITS FAVORABLE COST, SUPPORT, AND RESILIENCE CHARACTERISTICS. HOWEVER, SMOKE AND TOXIC GAS EVOLUTION IN THE EVENT OF FIRE IS A MAJOR PROBLEM. THE GOAL OF THIS PROGRAM IS TO CREATE A FIRE RESISTANT COMPOSITE FOAM STRUCTURE WHICH WILL GENERATE NEGLIGIBLE QUANTITIES OF TOXIC FUMES WHEN EXPOSED TO FI ...

THIS PROPOSED STUDY WILL EXAMINE THE FEASIBILITY OF USING A EULERIAN LIMITED AREA MODEL (LAM) TO IMPROVE PREDICTION OF CHEMICAL, BIOLOGICAL, AND OBSCURANT CLOUDS DURING AMPHIBIOUS OPERATIONS. THE LAM HAS BEEN USED TO PREDICT MESOSCALE AND MICROSCALE METEORO LOGICAL PHENOMENA FOR A WIDE VARIETY OF CLIMATIC REGIMES AND HAS BEEN TESTED FOR A NUMBER OF EXTENSIVE METEOROLOGICAL FIELD EXPERIMENTS. THE L ...

LOW-COST CIG SIMULATORS FOR WEAPONS TRAINING COULD BE PRODUCED THROUGH THE USE OF VLSI CHIPS SPECIFICALLY DESIGNED TO CARRY OUT THE MAJOR FUNCTIONS OF IMAGE GENERATION, NAMELY 3-D PERSPECTIVE, DIFFUSE REFLECTION AND SHADING, HIDDEN SURFACE REMOVAL AND OCCULTATION IN GENERAL, CLIPPING AND AREA FILL. THESE CHIPS WILL BE FAST ENOUGH TO ALLOW COMPUTATION AT 60 FRAMES/SEC WITH A RESOLUTION OF 1024 X 10 ...
