FOR ROTORCRAFT IN A NAP-OF-THE-EARTH (NOE) FLIGHT REGIME, COLLISION WITH WIRES PRESENTS A SIGNIFICANT THREAT TO SAFETY. WIRE DETECTION AND AVOIDANCE IS THUS AN IMPORTANT PART OF SAFE NOE GUIDANCE. WIRE DETECTION CAN BE DIFFICULT:WIRES ARE OFTEN NOT STRONGLY SPATIALLY EVIDENT, DANGEROUS WIRES OFTEN OCCUR AT THE FOCUS-OF-EXPANSION (FOE), THERE IS OFTEN SIGNIFICANT BACKGROUND CLUTTER AND NOISE, AND T ...

NETCON (NEW THERMIONIC CONVERTER) IS A NEW IDEA FOR AN ADVANCED POWER CONVERSION SYSTEM. THE EMITTERS ARE TYPICALLY 0.5 CM IN DIMENSION. THE EMITTER AND COLLECTOR ARE SEPARATED BY LESS THAN 0.5 MILS ( 12 MU M), WITH OPERATION IN THE QUASI-VACUUM (UNIGNITED) MODE. THE INTERELECTRODE GAP IS SET BY THE THERMAL EXPANSION OF A CERAMIC PEDESTAL SUPPORTING THE EMITTER. HEAT TRANSPORT TO THE EMITTER IS BY ...

THE PROPOSED R&D WILL ESTABLISH A NEW CAPABILITY OF LIGHT-ELEMENT X-RAY FLUORESCENCE ANALYSIS THAT SUPPORTS THE ACCURATE QUANTITATIVE MEASUREMENT OF THE BIOGENIC ELEMENTS. THE BASIS FOR THIS NEW CAPABILITY IS A CLASS OF INNOVATIVE X-RAY WAVELENGTH-DISPERSIVE OPTICAL COMPONENTS KNOWN AS LAYERED SYNTHETIC MICROSTRUCTURES (LSM). THESE COMPONENTS, WHEN COMBINED WITH EXISTING ENERGY-DISPERSIVE DETECTOR ...

THE DEVELOPMENT OF AN AUTOMATED TEST METHOD TO EXTRACT CMOS VLSI CIRCUIT PARAMETERS TO ASSESS HOT-ELECTRON RELIABILITY AND RADIATION HARDNESS IS PROPOSED. THE INSTRUMENT, COMBINED WITH STANDARDIZED TEST CHIPS, WOULD BE UNIQUELY SUITED FOR QUALIFICATION OF LOW-VOLUME ASIC CIRCUITS FOR SPACEBOURNE APPLICATIONS. THE PROPOSED CONCEPTINCLUDES THE DEVELOPMENT OF AUTOMATED TRANSFER OF TEST DEVICES BETWEE ...

THE OBJECTIVES OF THE PHASE I EFFORT ARE TO QUANTIFY THE EFFECT OF X-RAY SCATTER ON RADIOGRAPHIC IMAGE QUALITY, TEST SCATTER REJECTION APPROACHES, AND GENERATE A CONCEPTUAL DESIGN OF A SYSTEM WHICH WILL PROVIDE BETTER RESOLUTION, CONTRAST SENSITIVITY, AND DYNAMIC RANGE THAN IS CURRENTLY AVAILABLE WITH COMMERCIAL REAL-TIME RADIOGRAPHY SYSTEMS. PRESENTLY, REAL-TIME RADIOGRAPHY SYSTEMS DO NOT REJECT ...

VERY-HIGH-ALTITUDE, LONG-ENDURANCE (VHALE) TYPE AIRCRAFT OPERATE OVER A WIDE POWER RANGE DUE TO ALTITUDE AND FUEL LOAD CHANGES. MATCHING THE PROPELLER TO THE ENGINE OVER THIS RANGE IS DIFFICULT WITHOUT A COMPLICATED VARIABLE-PITCHPROPELLER OR GEARING. PASSIVE, OPTIMAL-PITCH CONTROL IS THEGOAL OF THIS PROJECT. THE CONCEPT CONSISTS OF AN AERODYNAMICALLY TAILORED BLADE, BALANCE WEIGHTS, AND TORSIONAL ...

MOST POWER PLANTS CURRENTLY BEING USED FOR AERONAUTICAL PROPULSIVE PURPOSES FUNCTION BY BURNING LIQUID FUELS IN THEIR COMBUSTION CHAMBERS. THEREFORE, THE DESIGN AND DEVELOPMENT OF EFFICIENT PROPULSION SYSTEMS REQUIRE THE COMPLETE UNDERSTANDING OF SPRAY COMBUSTION PROCESSES. TOWARDS THIS END, SEVERAL THEORETICAL MODELS HAVE BEEN DEVELOPED OVER THE YEARS, BUT THEIR CAPABILITIES ARE STILL OPEN TO QUE ...
