DEVELOPMENT OF A PLAN AND ITS DEMONSTRATION IN PRODUCING MODERN DATABASE FOR RV TECHNOLOGIES IS PROPOSED BY USING CLOUD MICROPHYSICAL DATA SETS COLLECTED SINCE 1985 OVER THE NORTH AMERICAN CONTINENT AND U.S. ARMY KWAJALEIN ATOLL. THE PLAN INCLUDES THE USE OF AIRBORNE RADAR, MODELING, AND SATELLITE ADDITIONS TO THE PARTICLE SIZE DATA TO CORRELATE PARTICLE SIZE AND LIQUID WATER CONTENT OVER AN EXTEN ...

DESIGN AND FABRICATION OF SOLID-STATE DIRECTION-INDICATING APPARATUS, WITH TILT-IMMUNITY, THAT PROVIDES AN AUDIBLE OR TACTILE INTERFACE WITH THE USER. REDUCED SIZE TO ALLOW ENCAPSULATION IN A TYPICAL WALKING CANE. A DEVICE WILL BE DESIGNED THAT WILL PROVIDE A VISUALLY IMPAIRED PERSON WITH AN INDICATION OF HORIZONTAL DIRECTION, WITH RESPECT TO THE EARTH'S MAGNETIC FIELD. THE DEVICE WILLALSO SIGNAL ...

A FAMILY OF ELECTRONICALLY STEERED CIRCULAR PHASED ARRAY ANTENNAS ARE CONFIGURED FOR USE ON SPINNING RE-ENTRY VEHICLES (RV). THIS TECHNIQUE ALLOWS RVS FROM SIX INCHES TO TEN FEET DIAMETER TO ACHIEVE GREATLY INCREASED PERFORMANCE COMPARED TO PRESENT SYSTEMS: CONTINUOUS RANGE SAFETY ACHIEVED THROUGHOUT RV FLIGHT; SIGNIFICANTLY HIGHER DATA RATES FROM IMPROVED DATA MONITORING; REQUIRED SPATIAL COVERAG ...

WE PROPOSE TO DEVELOP METHODS TO SOLVE ONE OF THE CRITICAL PROBLEMS OF TURBULENCE MODELLING INVOLVED IN HYPERSONIC FLOW IN WHICH ALL TRADITIONALLY USED TURBULENCE MODELS FAIL, NAMELY MODELLING OF KINETIC MIXING AND CHEMICAL REACTION PROCESSES IN HIGH MACH NUMBER (MA-25) TURBULENT FLOWS. WE PROPOSE TO DEVELOP DIFFERENTIAL TRANSPORT MODELS BASED ON OUR NEW RENORMALIZATION-GROUP (RNG) THEORY FOR TURB ...

OPTICAL LOGIC DEVICES ARE SOUGHT BY MANY INSTITUTIONS TO BE USED IN DIGITAL OPTICAL SIGNAL PROCESSING SYSTEMS. THE DEVICES PROPOSED HERE ARE PARTLY A CONTINUATION IN THE EVOLUTION OF GAAS-BASED GATES, BUT THEIR INCORPORATION OF LASING CHARACTERISTICS PRODUCES REVOLUTIONARY ADVANTAGES IN SYSTEM RELIABILITY AND SIMPLICITY. THEY ARE BASED ON THE VERTICAL CAVITY SURFACE-EMITTING MICROLASERS WHICH THE ...

IN ORDER TO ACHIEVE THE TECHNOLOGY AND LIFE CYCLE GOALS TARGETS FOR THE ADVANCED TURBINE ENGINES OPERATING BETWEEN -60 DEG AND 1500 DEG F, SOLID LUBRICANTS OFFER A VIABLE APPROACH. DURABILITY LIMITATIONS FOR SUCH ENGINES RESULT FROM HIGH OPERATING TEMPERATURES AND THE ELIMINATION OF COOLING SYSTEMS. THESE FACTORS MINIMIZE THE EFFECTIVENESS OF CONVENTIONAL OIL OR GREASE LUBRICANT DUE TO THERMAL AND ...

THE OBJECTIVE OF THIS PROJECT IS TO DEMONSTRATE EXPERIMENTALLY A NOVEL APPROACH TO DELIVERING A SOLID POWDER AS AN AEROSOL OF IMPROVED STABILITY. THE PROPOSED SYSTEM WILL BE DESIGNED SPECIFICALLY FOR THE DELIVERY OF MOLYBDENUM DISULFIDE TO THE BEARINGS OF THE DEVELOPMENTAL ADVANCED AIRCRAFT GAS TURBINE, WHICH MAY OPERATE BETWEEN THE EXTREMES OF -60 DEG F AND 1500 DEG F. THE AVAILABLE LIQUID LUBRIC ...

THE PURPOSE OF THIS PROPOSED PROGRAM IS TO DEVELOP A DIAMOND TRANSMIT/RECEIVE (T/R) SWITCH FOR HIGH POWER, HIGH FREQUENCY RADAR SYSTEMS. THE DIAMOND ELECTRONIC DEVICE MOST LIKELY TO ACHIEVE THE DESIRED T/R SWITCH SPECIFICATIONS IS AN INSULATED GATE FIELD EFFECT TRANSISTOR (IGFET) OPERATED AS A SWITCHING POWER TRANSISTOR. DIAMOND MATERIALS, INC. (DMI), PLANS TO DEVELOP A DIAMOND IGFET T/R SWITCH IN ...

CURRENT TOP-ATTACK ANTI-ARMOR MUNITIONS CONTAINING SELF-FORGINGFRAGMENT (SFF) WARHEADS ARE DEDICATED DESIGNS THAT ARE INTENDED TO DEFEAT A SPECIFIC TYPE OF TARGET AND ARE GENERALLY LESS EFFECTIVE AGAINST OTHER TARGETS. THUS ONE TYPE OF WARHEAD DESIGN IS PRESENTLY USED AGAINST HARD TARGETS, SUCH AS TANKS, AND A DIFFERENT TYPE IS USED AGAINST SOFT TARGETS, SUCH AS ARMORED PERSONNEL CARRIERS OR TRUCK ...
