THERE HAS BEEN LITTLE, IF ANY, DEVELOPMENT IN RECENT YEARS IN THE AREA OF MECHANICAL SHOCK (MS) SENSORS, ESPECIALLY SENSORS WITH HIGH FREQUENCY AND HIGH-G RESPONSE. IT IS PROPOSED THAT THROUGH THE USE OF LITERATURE SOURCES AN ASSESSMENT BE MADE OF THE STATE-OF-THE-ART IN MS SENSORS AND OF THE IMPROVABILITY OF THE MOST ADVANCED DEVICES TO EXTEND THEIR FREQUENCY AND DYNAMIC RANGE. IT IS ALSO PROPOSE ...

THERMOPLASTIC COMPOSITES SUCH AS FIBERGLASS/PPS ARE STRONG, LIGHTWEIGHT, TOUGH MATERIALS SUITABLE FOR HARSH ENVIRONMENTS WHERE WEIGHT SAVINGS AND DURABILITY ARE REQUIRED. THIS PROGRAM IS DESIGNED TO APPLY THOSE BENEFITS TO TEMPORARY ROADWAY SURFACES FOR MILITARY BRIDGE SITE ACESS/EGRESS. AFTER A REVIEW OF PRIOR WORK, ESPECIALLY TESTING OF SANDWICH PANELS, IMPROVED PANEL UTILIZING FIBERGLASS/PPD SK ...

THERMOPLASTIC MATRIX COMPOSITE MATERIALS SUCH AS GRAPHITE/PEEK AND GLASS/ULTEM OFFER GREAT POTENTIAL AS STRUCTURAL MATERIALS FOR HELICOPTER AIRFRAMES. THROUGH THE USE OF THERMOPLASTIC MATRIX COMPOSITES IT IS POSSIBLE TO BUILD THE LIGHTWEIGHT, DURABLE, DAMAGE TOLERANT STRUCTURE REQUIRED FOR HELICOPTERS. THIS PROGRAM IS DESIGNED TO DEVELOP AN AUTOMATED FIBER-REINFORCED THERMOPLASTIC FIBER PLACEMENT ...

THE PROPOSAL IS CONCERNED WITH THE DEVELOPMENT OF A NEW CONCEPT FOR THE CONTROL OF THE AERODYNAMICS OF HELICOPTER ROTOR BLADES. SUCH A CONTROL DEVICE WILL MAKE IT POSSIBLE TO MECHANIZE THE HELICOPTER ROTOR AIR FOIL MUCH IN THE SAME WAY THAT THE WINGS OF FIXED WING AIRCRAFT ARE MECHANIZED TO ACHIEVE HIGH LIFT, STALL-FREE PERFORMANCE AT LOW SPEEDS. EXISTING METHODS FOR ACTIVE CONTROL OF HELICOPTER R ...

MERCURY CADMIUM TELLURIDE (MCT) HAS EMERGED AS THE SUPERIOR MATERIAL FOR INFRARED APPLICATIONS IN IMPORTANT 3-5 MICROMETER AND 8-13 MICROMETER RANGES CORRESPONDING TO ATMOSPHERIC WINDOWS. BULK GROWTH METHODS CANNOT PROVIDE DEVICE GRADE LARGE AREA CRYSTALS OF THIS MATERIAL. HENCE, IN ORDER TO REALIZE THE STATE-OF-THE-ART LARGE AREA DEVICES, EPITAXIAL GROWTH IS THE ONLY PLAUSIBLE TECHNIQUE AT THE PR ...
