THREE AREAS OF ACTIVE MISSILE WING RESEARCH WILL BE PURSUED. THE FIRST SECTION WILL EVALUATE THE MATERIALS TO BE USED IN THE INFLATABLE WING SPARS, RIBS, SKINS, PRESSURE BLADDERS AND ACTIVE ELEMENTS. SPECIMENS OF HIGH ORTHOGONALITY COMPOSITES (POLYURETHANE-GRAPHITE) WILL BE CONSTRUCTED ALONG WITH SAMPLE ISOTROPIC BLADDER MATERIALS (MYLAR OR TEFLON) SO THAT THEIR FUNDAMENTAL PROPERTIES CAN BE EVALU ...

MOUTHSTICKS OR ORTHODONTIC ORTHOSES ARE WIDELY USED BY PEOPLE WITH SPINAL CHORD INJURIES OR SIMILAR DISABILITIES TO INCREASE CONTROL OVER THEIR ENVIRONMENT. PEOPLE WITH THE ADDITIONAL LIMITATION OF LITTLE OR NO ANTERIOR/POSTERIOR HEAD MOTION MAY BENEFIT FROM AN EXTENDIBLE MOUTHSTICK. HOWEVER, COMMERCIAL EXTENDIBLE MOUTHSTICKS SUFFER IN THAT THEIR ACTION IS OFTEN SLOW, EXTENDIBILITY IS LIMITED, OR ...

ASTROPOWER IS PROPOSING THE DEVELOPMENT OF AN ULTRA-LIGHTWEIGHT, HIGH PERFORMANCE, THIN LIGHT TRAPPING GAAS SOLAR CELL FOR ADVANCED SPACE POWER SYSTEMS. A THIN DEVICE LEADS TO HIGHER PERFORMANCE IN TERMS OF OPEN CIRCUIT VOLTAGE, RADIATION RESISTANCE, AND SPECIFIC POWER. IN A THIN DEVICE, THE INCORPORATION OF LIGHT TRAPPING TO EXTEND THE OPTICAL PATH LENGTH PERMITS GREATER CURRENT GENERATIC THAN CA ...

Three areas of research on low cost, reliable, folding aero surfaces will be conducted. First, different types of fin deployment and flight control actuators will be examined. These include conventional fin actuators, shape-memory-alloy, piezoelectric, magnetostrictive, and electrostrictive actuators. Second, different fin designs will be examined. These candidate designs are capable of flight con ...

REMOVAL OF TOXIC METALS FROM WASTEWATER STREAMS HAS BECOME A PROBLEM OF INCREASING NATIONAL IMPORTANCE, AS A RESULT OF INCREASING CONCERN FOR OUR ENVIRONMENT, AND INCREASINGLY STRINGENT WASTE DISPOSAL REGULATIONS. CHROMATOCHEM, INC., HAS DEVELOPED AN ECONOMICAL AND EFFECTIVE NEW TECHNOLOGY FOR THE REMOVAL OF LOW LEVELS OF TOXIC METAL IONS FROM WASTEWATER STREAMS, USING SOLID PHASE EXTRACTION (SPE) ...

Targets designed to withstand the effects of conventional (nonnuclear) munitions are assessed using standard vulnerability assessment methods. These assessment tools usually consider variabilities in site characteristics, target attributes like strength and stiffness, and weapon delivery charactenstics. Current vulnerability procedures are overly conservative in that, to ensure high confidence in ...
