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 ...

AN EXPERIMENTAL APPARATUS WILL BE FABRICATED FOR INSTRUMENTED OPERATION OF CURRENT COLLECTORS IN CONTROLLED ATMOSPHERES. TERNARY ALLOYS OF GALLIUM, INDIUM AND TIN WILL BE MADE AND APPLIED TO SURFACES OF THE CURRENT COLLECTORS AND SUBJECTED TO OPERATION, ACCOMPANIED BY OBSERVATION OF FRICTION, WEAR, CONTACT RESISTANCE, AND CHEMICAL COMPOSITION OF THE FILM AND WEAR DEBRIS. INFORMATION OBTAINED WILL ...

COMMERCIALLY AVAILABLE IN-STACK TRANSMISSMETERS FOR OPACITY MEASUREMENT PRESENTLY ONLYHAVE THE CAPABILITY OF A ONE POINTDYNAMIC UPSCALE CHECK OR NO DYNAMIC UPSCALE CHECK DURING OPERATION. IN ORDER TO PERFORM NECESSARY MULTI-POINT AUDITSOF LINERARITY CHECKS, THE INSTRUMENT MUST BE REMOVED FROM SERVICE OR AT THE LEAST BE MANUALLY FITTED WITH AN EXTERNAL AUDIT DEVICE. THIS REQUIRES ACCESS TO THE INST ...

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 ...
