THE OBJECTIVE OF THE PROPOSED WORK IS TO USE ADVANCED THEORETICAL AND COMPUTATIONAL TECHNIQUES FOR STUDIES OF HYPERSONIC BOUNDARY LAYER STABILITY AND TRANSITION TO TURBULENCE. THESE STUDIES WILL ENHANCE OUR UNDERSTANDING OF THE TRANSITION PHENOMENA AND THUS HELP PREDICT AND CONTROL TRANSITION WITH A HIGH DEGREE OF CONFIDENCE. TO ACHIEVE OUR GOAL, WE USE LINEAR STABILITY THEORY, SECONDARY INSTABILI ...

THIS PROJECT WILL EXAMINE THE NEEDS OF OLDER PERSONS FOR IMPROVEMENTS IN THE INTERFACE DESIGNS OF HAND-HELD CONTROL UNITS FOR REMOTELY CONTROLLING EQUIPMENT AND SOFTWARE, ESPECIALLY TELEROBOTS. THESE REMOTE CONTROL UNITS (RCUS), PROLIFERATING WITHOUT ADEQUATE HUMAN FACTORS ENGINEERING, WILL BE USED INCREASINGLY BY SENIORS IN THEIR HOMES AND AT WORK. THE ONLY STUDY OF RCUS INDICATES THAT THEIR OPER ...

IT IS PROPOSED TO INVESTIGATE AND DEVELOP INNOVATIVE PROPELLER BLADE SECTION GEOMETRY WHICH WILL RESULT IN IMPROVED ACOUSTIC AND POWERING PERFORMANCE OF SURFACE SHIPS THROUGH THE ATTAINMENT OF HIGHER CAVITATION INCEPTION SPEEDS AND REDUCE BLADE DRAG. THESE SECTIONS ARE CHARACTERIZED BY A BLUNT TRAILING EDGE WITH A SEPARATED, NONCAVITATING WAKE. THE EFFECT OF THE BLUNT TRAILING EDGE, WHEN COUPLED W ...

THE EFFICIENCY WITH WHICH ASSETS ARE ALLOCATED DURING COMBAT HAS USUALLY PLAYED A DOMINANT ROLE IN THE OUTCOME OF THE CONFLICT -OFTEN ECLIPSING ALL OTHER FACTORS, INCLUDING VARIANCES IN FORCE STRUCTURE. THE SOLUTION OF OPTIMAL ALLOCATION PROBLEMS IS NO LESS CRITICAL TO THE DESIGN AND OPERATION OF C3I NETWORKS. THUS, THE ABILITY TO PERFORM THIS ENABLING TASK AS EFFICIENTLY AS POSSIBLE IS VITAL. WE ...

WE PROPOSE TO DEVELOP A NEW HIGH-TEMPERATURE DIRECTIONAL SPECTRAL EMISSIVITY MEASUREMENT SYSTEM BASED ON A SPECIAL INTEGRATING SPHERE CONFIGURATION. CURRENTLY AVAILABLE SYSTEMS MEASURE ONLY THE NORMAL EMISSIVITY AT TEMPERATURES APPROACHING 1000 DEGREES CENTIGRADE WITH UNKNOWN ACCURACY, BY MEASURING THE EMITTED FLUX WHICH IS HIGHLY SENSITIVE TO TEMPERATURE UNCERTAINTIES. THE PROPOSED APPROACH MEASU ...

A RECENT BREAKTHROUGH IN THERMOPLASTIC MATERIALS TECHNOLOGY NOW PERMITS PRACTICAL, LIGHTWEIGHT, LOW VOLUME INTEGRATED STRUCTURE/ ENERGY STORAGE SYSTEMS TO BE FABRICATED. THESE MATERIALS WILL PERMIT SPACECRAFT WEIGHT AND VOLUME SAVINGS WHICH ARE NOT POSSIBLE WITH ANY OTHER SEPARATE STRUCTURE/SECONDARY BATTERY COMBINATION WHICH IS NOW UNDER CONSIDERATION. THIS PROPOSAL DESCRIBES A PHASE I CONCEPT FE ...

A NEW APPROACH TO ALKALI BATTERY DEVELOPMENT, WHICH CAN SATISFY THE DEMANDING HIGH RATE, HIGH SPECIFIC ENERGY SPACE MISSION REQUIREMENTS, IS PROPOSED. THE PROPOSED APPROACH OFFERS SPEPCIFIC ENERGY PERFORMANCE COMPARABLE TO THE BEST RECHARGEABLE LITHIUM BATTERY CHEMISTRIES CURRENTLY UNDER DEVELOPMENT, WITH SUBSTANTIAL INCREASES IN SPECIFIC POWER. THIS PROPOSAL DESCRIBES A PHASE I BATTERY CONCEPT FE ...

A RECENT BREAKTHROUGH IN POLYMER BATTERY TECHNOLOGY NOW PERMITS A PRACTICAL, VERY HIGH ENERGY DENSITY, LONG LIFE SECONDARY BATTERY TO BE FABRICATED. THIS PROPOSAL DESCRIBES A PHASE I CONCEPTUAL DESIGN STUDY AND PRELIMINARY CELL EVALUATION. PHASE II WILL CULMINATE WITH THE DEMONSTRATION OF A PROTOTYPE 600 WH/KG BATTERY.
