PRESENT COMPUTER MODELS USED TO PREDICT VAPOR CLOUD LENGTH, CONCENTRATION AND DURATION AT AIR FORCE INSTALLATIONS DO NOT PROPERLY ACCOUNT FOR THE EFFECTS OF STRUCTURES. STRUCTURES CAN ACT TO TRAP THE CLOUD AND INCREASE THE CLOUD DIMENSIONS, THEREBY POSSIBLY REDUCING DOWNWIND CONCENTRATIONS AND INCREASING THE CLOUD'S LATERAL EXTENT. RECENT RESEARCH CONDUCTED BY CPP HAS SHOWN THAT THE TRAPPING AND I ...

SOLID-STATE LASER SYSTEMS HAVE BEEN IDENTIFIED AS A PARTICULARLY EFFECTIVE TRANSMITTER TECHNOLOGY FOR USE IN COHERENT LASER RADAR SYSTEMS, DUE TO THEIR NEAR-IR WAVELENGTH (1-2UM), COMPACTNESS, FREQUENCY AGILITY, AND EFFICIENCY. RECENT ADVANCES IN LASER DIODE ARRAY TECHNOLOGYHAVE OPENED NEW PROSPECTS FOR LONG LIFE, HIGH ENERGY AND AVERAGE POWER SOLID-STATE LASER RADAR INSTRUMENTS SUITABLE FOR EXTEN ...

THE EAGLE GRID GENERATION CODE IS A WIDELY USED SOFTWARE TOOL FOR GENERATING COMPUTATIONALLY UNIFORM GRIDS THAT FIT IRREGULAR PHYSICAL DOMAINS. BASED ON ELLIPTIC GRID GENERATION, IT USES A BLOCKSTRUCTURED APPROACH TO ACCOMMODATE VERY IRREGULAR REGIONS AND POINT DISTRIBUTION FUNCTIONS TO REDUCE FLOW-SOLVER TRUNCATION ERROR. IT ALSO INCORPORATES AS EULER SOLVER FOR INVISCID FLOW CALCULATIONS. WHILE ...

A HYPERGOLIC FUEL INJECTOR IS DESCRIBED THAT ENABLES MULTIFUEL OPERATION, LOWER FUEL CONSUMPTION, AND ENHANCED ALL WEATHER STARTING FOR INTERNAL COMBUSTION ENGINES. THE DEVICE EMPLOYS A NOVEL DUAL FUNCTION HIGH PRESSURE PUMP PERMITTING THE TRANSPORT OF HEATED FUEL IN A FUEL INJECTOR SUITABLE FOR USE IN SUCH ENGINES. HIGH TEMPERTURE AND VERY HIGH PRESSURE FUEL IS DELIVERED TO THE COMBUSTION SPACE O ...

THE ADVENT OF THE CORDRAY ROTARY ENGINE HAS MADE POSSIBLE SUBSTANTIAL INCREASES IN THE POWER TO WEIGHT RATIO AVAILABLE TO THE AIRCRAFT DESIGNER. ENGINE SELECTION IS HISTORICALLY THE PRIMARY DETERMINATIVE OFVEHICLE DESIGN AND PERFORMANCE. THE AVAILABILITY OF THIS ENGINE ALONGWITH ADVANCES IN COMMAND AND CONTROL ELECTRONICS MAKES POSSIBLE A NEW CLASS OF VEHICLE CAPABLE OF VERTICAL TAKE OFF AND THEN ...

WHILE MILITARY APPLICATIONS OF MIDAND FAR-INFRARED SENSING ARE INCREASING, THERE ARE VERY FEW TECHNOLOGIES AVAILABLE FOR LIGHT MODULATION IN THOSE SPECTRAL BANDS. WE PROPOSE TO DEVELOP NON-MECHANICAL SHUTTERS USING THE ELECTRO-OPTIC EFFECT IN FERROELECTRIC LIQUID CRYSTALS. THE SHUTTERS WE PROPOSE WILL BE SMALL AND RUGGED, AND HAVE HIGH THROUGHHPUT (70-90%), HIGH ON:OFF CONTRAST (40:1 OR GREATER), ...
