N/A

EXPERIMENTAL INVESTIGATTIONS ARE PROPOSED ON FUEL ATOMIZATION AND AIR-FUEL INTERACTIONS IN A TURBULENT ENVIRONMENT. UNDER THE PROPOSED PROGRAM THE TWO BASIC AREAS OF RESEARCH WILL BE ADDRESSED; COLD FLOW SPRAY CHARACTERIZATIONS IN A TURBULENT FLOW FIELD WITH AND WITHOUTEVAPORATION AND DROP DRAG DETERMINATIONS WITHIN A POLYDISPERSION. DETAILED SPRAY DROP SIZE AND VELOCITY AND GASEOUS FLOW TURBULENC ...

N/A

THE FEASIBILITY AND ECONOMICS OF USING TETHERS FOR STATION-KEEPING OR SLING LAUNCH OF PAYLOADS IS HIGHLY DEPENDENT ON THE RELIABLE CONTROL OF THE TETHER ITSELF IN ANENVIRONMENT. THE PROPOSED TETHER DEPLOYMENT MONITORING SYSTEM (TDMS) WOULD PROVIDE DATA ON THE TETHER'S CONDITION, GUIDANCE IMFORMATION, AND EARLY WARNING ON POSSIBLE FAILURE CONDITIONS. INSTRUMENT PACKAGE WOULD BE DEPLOYED ALONG THE T ...

N/A

THERE IS A CRITICAL NEED TO MEASURE STRUCTUREBORNE NOISE TRANSMISSION IN AIRCRAFT, PARTICULARLY THOSE POWERED BY THE ADVANCED TURBOPROP. IT IS PROPOSED THAT A STRUCTUREBORNE INTENSITY MEASUREMENT PROCEDURE BE FORMULATED AND DEVELOPED FOR IN-FLIGHT APPLICATION. THE PROCEDURE WOULD INCLUDE CONSIDERATION OF FLEXURAL, LONGITUDINAL AND ROTATIONAL WAVE COMPONENTS, SINCE THEY ALL CONTRILUTE TO THE TRANSM ...

THE OBJECTIVE OF THE RESEARCH PROJECT IS TO DEVELOP AND TO CONFIGURE A SYSTEM WHICH WILL AUTOMATICALLY IDENTIFY, CLASSIFY, AND COUNT SHAPES OR GRANULES IN A PERVASIVE BACKGROUND. THE FIRST INTENDED APPLICATION FOR THE SYSTEM IS FOR AEROSOL PARTICLE ANALYSIS. OF IMMEDIATE INTEREST IS THE CLASSIFICATION OF SULFURIC ACID IN THE STRATOSPHERE. ATAC WOULD ENHANCE AND PROVE THE FEASIBILITY OF A CONCEPT S ...

RECENTLY, A CLINICALLY VALIDATED RELATIONSHIP BETWEEN DETERMINATION OF EJECTION FRACTION CALCULATED FROM (1) NON-INVASIVE MEASUREMENT OF THE SYSTOLIC TIME INTERVALS OF THE ECG AND PHONO-CARDIOGRAPHY OR CAROTID ARTERY TRACING, AND EJECTION FRACTION AS MEASURED BY (2) INVASIVE METHODS, SUCH AS REDIONUCLIDES OR CINE-ANGIOGRAPHY, HAS BEEN ESTABLISHED. THE ON-GOING RESEARCH IN THE FIELD OF ELECTRICAL B ...

THE ARTICULATED ROBOT MANIPULATOR (ARM) IS A LIGHTWEIGHT FLEXABLE ARM CAPABLE OF QUICKLY AND ACCURATELY POSITIONING ALOAD OF 100 KILOGRAMS OVER A TEN METER RADIUS. ARM WILL USEMIXED LASER AND BEAM POSITIONING AND COMMUNICATIONS SYSTEMS TO INTERNALLY SENSE THE EFFECTOR POSITIONS. ARM WILL BE CONSTRUCTED OF SEGMENTS AND ARTICULATIONS. SEGMENTS WILL BELONG, THIN, FLEXABLE, AND INTERCHANGABLE; THEY MA ...

RECENT ADVANCES IN PYROELECTRICS HAVE PROVIDED MATERIALS WHICH MAY BE USEFUL IN THE DIRECT CONVERSION OF HEAT INTO ELECTRICAL ENERGY IN SPACE SYSTEMS. THESE MATERIALS WILL BEMANUFACTURED AT LOW COST AND PROVIDE A LIGHTWEIGHT MEANS OF GENERATING ELECTRICAL POWER AND RADIATIVELY DUMPING REJECT HEAT. THE OJBECTIVE OF THE PHASE I EFFORT IS TO DETERMINE THE EFFECTS OF RADIATION EXPOSURE ON THE PYROELEC ...
