THE TREND IN ALL MATERIALS IS TOWARD THE CONTROL OF MICROSTRUCTURE. IN CERAMICS AND CERMETS THE EMPHASIS IS ON THE REDUCTION OF CRYSTALLITE SIZE AND THEREBY ON IMPROVING PHYSICAL PROPERTIES. POWDERS SHOULD BE EQUIZAXED AND LIMITED TO SUBMICRON RANGE, WITHIN A NARROW AND SPECIFIC SIZE DISTRIBUTION. EVEN MORE IMPORTANTLY LARGE QUANTITIES OF POWDERS MUST BE AVAILABLE AT REASONABLE COST. AS PRESENTLY ...

THE ABILITY TO FABRICATE CERAMIC ARMOR ECONOMICALLY IS DEPENDENT UPON SEVERAL FACTORS INCLUDING POWDER COST, FABRICATION TECHNIQUE, AND FINAL MACHINE COST. CANDIDATE CERAMIC SUCH AS TIB (2), AND B (4)C DO NOT SINTER TO FULL DENSITY. THEREFORE, NEAR-NET SHAPE FORMATION IS DIFFICULT AND EXPENSIVE, ESPECIALLY WHERE COMPLEX GEOMETRIES ARE INVOLVED. ART PROPOSES TO UTILIZE NEW POWDER SYNTHESIS TECHNOLO ...

THE ESTIMATION OF THE COMPUTER CAPACITIES REQUIRED TO SUPPORT A MISSION ARE USUALLY THE SUBJECT OF MUCH DISCUSSION. ESTIMATES OF THE WORKLOAD AND OTHER PARAMETERS VARY GREATLY. THE REASON FOR THIS IS THAT MOST APPLICATIONS DO NOT FIT THE TRADITIONAL TIMING AND SIZING EFFORT. NONE OF THE THREE COMPONENTS (WORKLOAD, PERFORMANCE REQUIREMENTS AND ARCHITECTURE) IS USUALLY PRESENT. WE CONTEND THAT THE M ...

THE HIGHLY SUCCESSFUL BOUNDARY LAYER ACOUSTIC MONITOR (BLAM) PROGRAM PRODUCED BLAM GAUGES WHICH WERE USED ON MINUTEMAN FLIGHTS TO TEST FLOW AROUND RE-ENTRY VEHICLES (RV), AND DETECT THE LOCATION OF THE TRANSITION TO TURBULENT FLOW. IT IS POSTULATED THAT THESE BLAM GAUGES CAN BE RECONFIGURED TO OPERATE TO DETECT TURBULENT FLOW IN WATER TUNNELS. IN ORDER TO EFFECT THIS REDESIGN, THE WATER TUNNEL ENV ...

THE PURPOSE OF THIS DEVELOPMENT PROPOSAL IS TO DEMONSTRATE HIGH SPEED RANGING AND CLASSIFICATION OF OBJECTS WITH A VERSION OF A&F'S PROPRIETARY 3D VISION SYSTEM. THIS SYSTEM HAS ALREADY DEMONSTRATED TARGET CLASSIFICATION AND RANGING IN REALISTIC ENVIRONMENTS IN WORK SUPPORTED BY NSWC. THE EMPHASIS OF THIS PROJECT IS TO INCREASE THE SPEED OF THE SYSTEM FROM IT'S PRESENT LEVEL.

TWO MECHANISMS ARE IDENTIFIED BY WHICH AN ELECTRICALLY CHARGED ROTORCRAFT MIGHT ACT AS A SOURCE OF ELECTROMAGNETIC RADIATION. THESE ARE NARROW BAND ELF RADIATION PRODUCED BY CURRENTS INDUCED BY ROTOR ROTATION AND BROADBAND ELECTROMAGNETIC RADIATION FROM P STATIC. IN ORDER TO DETERMINE WHETHER OR NOT RADIATION DUE TO THESE MECHANISMS IS DETECTIBLE A COMBINATION OF NUMERICAL MODELLING TECHNIQUES IS ...
