IN HYPERSONIC CRUISE, THE OUTER SURFACE OF A VEHICLE MADE OF A COMPOSITE MATERIAL ABLATES. THE ABLATED PARTICLES PENETRATE INTO THE BOUNDARY LAYER AFFECTING THE FLOW DYNAMICS AS WELL AS RADIATIVE AND CONVECTIVE HEAT TRANSFER TO AND FROM THE VEHICLE. THE AUTHORS PROPOSE TO PERFORM THEORETICAL ANALYSIS OF RADIATIVE AND CONVECTIVE HEAT TRANSFER IN A TURBULENT BOUNDARY LAYER OF HEAT RADIATION SCATTERI ...

GEOLOGIC MATERIAL PROPERTY REQUIREMENTS FOR NUMERICAL CALCULATION OF AN EXPLOSIVE EVENT DEPEND ON SEVERAL FACTORS, INCLUDING: THE PEAK PRESSURE EXPECTED OR ACHIEVED, THE GEOMETRY OF LOADING, AND THE TYPE OF CALCULATION BEING PERFORMED. ADDITIONALLY, THE CLASS OF GEOLOGIC MATERIAL INVOLVED; E.G., SAND VERSUS CLAY VERSUS ROCK, WILL DICTATE REQUIREMENTS BASED ON WHAT ARE ANTICIPATED TO BE THE IMPORTA ...

THE EFFECTIVENESS OF NON-NUCLEAR MUNITIONS AND ARMAMENTS IS ENHANCED IF TERMINAL GUIDANCE IS PROVIDED. ILLUMINATION OF THE TARGET FROM A SELF-CONTAINED TRANSMITTER PROVIDES THE GREATEST MISSION FLEXIBILITY. THE USE OF MILLIMETER WAVELENGTH TERMINAL GUIDANCE TARGET SEEKERS IS NOW UNDER FAVORABLE CONSIDERATION BECAUSE OF SUPERIOR PERFORMANCE RELATIVE TO OPTICAL WAVELENGTH SYSTEMS IN ADVERSE BATTLEFI ...

THE GUIDANCE OF SMALL MUNITIONS AND MISSILES USING SEEKER FRONT ENDS AT MILLIMETER WAVE LENGTHS HAS GAINES INCREASING DEVELOPMENT ATTENTION. MILLIMETER SEEKERS HAVE ADVANTAGES IN TERMS OF GROUND CLUTTER REJECTION AND OTHER BATTLE FIELD CONDITIONS (SMOKE AND DUST). THE MAJOR PROBLEM PLAGUEING THESE SYSTEMS TO DATE HAS BEEN THE HIGH COST DRIVEN BY THE INABILITY TO INTEGRATE AND MASS PRODUCE. MICROST ...

IT IS PROPOSED TO INVESTIGATE THE APPLICATION OF AN INNOVATIVE METHOD FOR SPACECRAFT THERMAL ENERGY MANAGEMENT AS WELL AS ENHANCED HEAT TRANSFER AND STORAGE IN ELECTRONIC SYSTEMS USING A TWO-COMPONENT SLURRY CONTAINING A MICROENCAPSULATED, PHASE-CHANGE MATERIAL (PCM). A DEMONSTRATION MODEL OF A THERMAL MANAGEMENT SYSTEM CONTAINING BOTH A PRIMARY BUSS AND A SECONDARY LOOP WILL BE DESIGNED, FABRICAT ...
