ADVANCED SHORT TAKEOFF/VERTICAL LANDING AIRCRAFT ARE DESIGNED TO USE EXHAUST JETS TO DIRECTLY INCREASE LIFT. BEING ABLE TO NUMERICALLY MODEL THE FLOW FIELDS INVOLVED IN THESE DESIGNS WOULD GREATLY IMPROVE THE DESIGN PROCESS. THEPROPOSED EFFORT IS TO DEVELOP A COST EFFECTIVE FLOW ANALYSISTOOL FOR MODELING POWERED-LIFT AIRCRAFT FLOW FIELDS. THE PHASE I OBJECTIVE IS TO DEMONSTRATE A ZONAL METHOD THAT ...

AN EXPERIMENTAL INVESTIGATION OF SHOCK WAVE/SHEAR LAYER INTERACTIONS TO ENHANCE MIXING IN A SUPERSONIC COMBUSTION RAMJET (SCRAMJET) ENGINE IS PROPOSED. IN A SCRAMJET ENGINE OPERATING AT HYPERSONIC FLIGHT SPEEDS, THE SHORTER RESIDENCETIME AND DECREASED MIXING RATE CAUSE DETERIORATION IN THE COMBUSTION EFFICIENCY AS COMPARED WITH LOWER SPEEDS. A CONFIGURATION RECENTLY DEVELOPED TO PROMOTE RAPID MIXI ...

ALTHOUGH BICYCLES HAVE LONG BEEN USED IN THE REHABILITATION OF NEUROMUSCULAR AND MUCULOSKELETAL CONDITIONS FOR BOTH LOW-ER AND UPPER EXTREMITIES, LITTLE RESEARCH HAS BEEN DONE TO INVESTIGATE THE EFFECTS OF THE TRADITIONAL CIRCULAR CRANKINGMOTION ON PATIENT REHABILITATION. RETURNING A PATIENCT TO OPTIMUM FUNCTION REQUIRES A VARIETY OF MEASURES TO INCREASE STRENGTH, RANGE OF MOTION, ENDURANCE (BOTH ...

A PATENT HAS RECENTLY BEEN ISSUED FOR AN IMAGING DOPPLER INTERFEROMETER (IDI) WHICH IS A SYSTEM FOR SIMULTANEOUSLY MONITORING THE CONTENTS OF A VOLUME OF SPACE WITHOUT SCANNING. TO DATE, THE IDI HAS BEEN USED SUCCESSFULLY FOR MEASURING WIND PATTERNS IN 3 DIMENSIONS. THIS RESEARCH EXAMINES THE FEASIBILITY OF USING THIS TECHNOLOGY FOR GEOMORPHOLOGY STUDIES. EXPECTED RESULTS ARE CONTINUOUS SWATH DATA ...

REMOTE ATMOSPHERIC SENSING AND SPACE BASED LIDAR SYSTEMS REQUIRE SOURCES IN THE NEAR INFRARED. SOURCES UNDER CURRENTDEVELOPMENT ARE QUASI-THREE LEVEL LASERS, SUCH AS CR:ER:YAG (1.6 UM) AND TM:HO:YAG (2.1 UM). OPERATION OF QUASI-THREE LEVEL LASERS IS TEMPERATURE DEPENDENT AND SUCH DEVICES HAVE INCREASED THRESHOLDS AND REDUCED EFFICIENCIES AT ROOM TEMPERATURE. WE PROPOSE A NEW FOUR-LEVEL SOLID-STATE ...

TRA PROPOSES THE DEVELOPMENT OF A SWITCHED HEMISPHERICAL ANTENNA FOR USE ON THE STS, SPACE STATIONS AND SATELLITES. THE ANTENNA HAS THE ABILITY TO SCAN OVER 2 PI STERADIANS, SAMPLE SIGNAL STRENGTH FROM A BEACON AND ROUTE DATA TO THE APPROPRIATE SECTOR. THE ON-BOARD COMPUTER MAY BE INTERFACEDTO AN INERTIAL REFERENCE FRAME ALLOWING THE CONTROLLER TO COMPENSATE FOR SATELLITE SPIN. TWO SUCH ANTENNAS W ...

THE PROJECT TESTS THE MERIT AND FEASIBILITY OF USING INTER- ACTIVE VIDEODISCS TO TRAIN TEACHERS, AND SUPPORT PERSONNEL FOR BEHAVIOR MANAGEMENT IN THE CLASSROOM AND TO DIRECTLY TRAIN STUDENTS AND PARENTS FOR BEHAVIORAL CONTROL. CONTROL-LING STUDENT BEHAVIOR IS OF THE HIGHEST PRIORITY IN MOST SCHOOLS. THE SEATTLE SCHOOL DISTRICT HAS ENDORSED THIS PROJECT AND IS SUPPORTING BOTH PRODUCTION AND TESTING ...
