THE OBJECTIVE OF THIS PROPOSAL IS TO DEVELOP A HIGH-ACCURACY, HIGHRANGE PRESSURE AND TEMPERATURE TRANSDUCER FOR THE MEASUREMENT OF RAPID TRANSIENTS TO 700 MPA AND TEMPERATURES TO 3000 K, AS WELL AS HEAT TRANSFER, IN GUN INTERIORS. ALL THREE MEASURING FUNCTIONS WILL BE PERFORMED BY ONE SMALL (ABOUT 20 MM IN DIAMENTER) SENSOR UNIT AND SOME EXTERNAL TEMPERATURE SENSORS. THE PRESSURE IS DETECTED BY CA ...

THIS PROPOSAL ADDRESSES THE DEVELOPMENT OF AN AUTOMATED ALIGNMENT MEASURING SYSTEM FOR THE HYPERVELOCITY RANGE/TRACK G FACILITY, LOCATED AT ARNOLD ENGINEERING DEVELOPMENT CENTER. THE OBJECTIVES OF THIS RESEARCH AND DEVELOPMENT EFFORT ARE TO EVALUATE METHODS FOR DEVELOPING A SYSTEM THAT CAN RAPIDLY AND COST-EFFECTIVELY INSPECT THE TEST TRACK. THIS WILL REQUIRE AN IN-DEPTH UNDERSTANDING OF THE ENVIR ...

AN EXPERIMENTAL INVESTIGATION OF INNOVATIVE FLAMEHOLDER DESIGNS TO ENHANCE MIXING IN A SUPERSONIC COMBUSTION RAMJET (SCRAMJET) ENGINE IS PROPOSED. IN A SCRAMJET ENGINE OPERATING AT HYPERSONIC FLIGHT SPEEDS,THE SHORTER RESIDENCE TIME AND DECREASED MIXING RATE CAUSE DETERIORATION IN THE COMBUSTION EFFICIENCY AS COMPARED WITH LOWER SPEEDS. TWO CONFIGURATIONS RECENTLY DEVELOPED TO PROMOTE RAPID MIXING ...

A SCANNING, PULSED DIODE LASER DOPPLER VELOCIMETER (DLDV/SP) WILL BE DEVELOPED FOR FLOW MEASUREMENTS IN AIR AND WATER, PARTICULARY COASTAL WATERS AND THE MARINE ATMOSPHERIC BOUNDARY LAYER. THE DLDV/SP, BASED ON A FIELD-PROVEN DLDV FOR OCEAN DEPLOYMENT UNDER ICE FLOWS, WILL BE DESIGNED FOR ON-AXIS BACKSCATTER OPERATION. IN A PULSED MODE, THE DIODE LASER WILL GENERATE INSTANTANEOUS LASER POWER IN TH ...

THE SAFETY OF THE FLYING PLATE DETONATOR IS KEY TO ITS USE IN IN-LINE FUZES. THE MAIN ADVANTAGE OF THE FLYING PLATE DETONATOR IS ONE OF ITS ADVANTAGES FROM A SAFETY VIEWPOINT; A SUBSTANTIAL AMOUNT OF ELECTRICAL ENERGY, ON THE ORDER OF A JOULE, MUST BE DELIVERED TO THE BRIDGE IN LESS THAN A MICROSECOND BEFORE THE UNIT WILL FIRE. THE FLYING PLATE DETONATOR, HOWEVER, HAS CHANGED LITTLE SINCE ITS ORIG ...

MOST OF THE ULTRASONIC SCANNING SYSTEMS IN SERVICE OR BEING INSTALLED AT DOD FACILITIES OFFER SOME MEANS OF RECORDING INSPECTION DATA. HOWEVER, THE ADVANTAGES OF THIS CAPABILITY AREN'T BEING FULLY REALIZED BECAUSE THE STORAGE MEDIA AND DATA ARCHIVAL FORMATS DIFFER FROM SYSTEM TO SYSTEM. THIS LACK OF STANDARDIZATION IS CAUSING A PROBLEM THAT IS BECOMING WIDESPREAD AS MORE AND MORE DOD FACILITIES IN ...

THIS PROPOSED WORK WILL EVALUATE THE USE OF ULTRA-HIGH PRESSURE (20,000 TO 55,000 PSI) WATERJETS AS A METHOD OF REMOVING COATINGS FROM SHIP'S HULL SYSTEMS. ULTRA-HIGH PRESSURE (UHP) WATERJETS ARE IN DAILY COMMERCIAL USE FOR NUMEROUS CLEANING AND COATING REMOVAL TASKS. THE ADVANTAGES OF UHP WATER INCLUDE: IMPROVE PRODUCTIVITY; LOWER REACTION THRUST RESULTING IN INCREASED OPERATOR SAFETY; ABILITY TO ...

IT HAS BEEN OBSERVED IN BOTH SMALL-SCALE EXPERIMENTS AND FULL-SCALE FUEL SYSTEM SIMULATORS THAT JET FUELS, WHEN HEATED, UNDERGO CHEMICAL REACTIONS THAT EVENTUALLY RESULT IN SEDIMENT/DEPOSIT FORMATION. THUS, THE THERMAL STABILITY OF JET FUELS HAS THE DELETERIOUS EFFECT OF CAUSING FUEL SYSTEM MALFUNCTIONS. THIS SITUATION IS ALSO POSSIBLE IN SUPERSONIC AIRCRAFT, WHERE AN INCREASE IN THE METAL SKIN TE ...

PERSONNEL WORKING IN EXTREME ENVIRONMENTS OR WEARING BALLISTIC AND/OR NUCLEAR/BIOLOGICAL/CHEMICAL (NBC) PROTECTIVE CLOTHING ARE SUBJECT TO THE HAZARDS OF OVERHEATING. THESE HAZARDS INCLUDE PHYSICAL DISCOMFORT, DECREASED PHYSICAL AND MENTAL ABILITIES, DEHYDRATION, AND EVENTUALLY DEATH FROM HEAT STRESS. THE NUMBER OF PERSONNEL VULNERABLE TO THESE HAZARDS IS ALREADY QUITE LARGE AND IS STEADILY INCREA ...
