THE OBJECTIVE OF THIS PROPOSAL IS THE DEVELOPMENT OF A PULSED MID-IR LASER IN THE 3.5 TO 4.1 MICROMETER ATMOSPHERIC TRANSMISSION WINDOW. SUCH SPECTRAL SOURCE IS RELEVANT TO A VARIETY OF TACTICAL APPLICATIONS. THE DF CHEMICAL LASER HAS BEEN THE CHOICE, BUT SUFFERS FROM WASTE FUEL MANAGEMENT PROBLEMS. NO OTHER EFFICIENT DIRECT LASING SOURCE IS AVAILABLE. TO OBTAIN SUCH A SOURCE, WE PROPOSE THE USE O ...

A SIX-MONTH RESEARCH PROGRAM IS DESCRIBED TO DEVELOP WAYS TOCOMPARE CONCURRENT DATA SAMPLES FROM A VARIETY OF IMAGING SENSOR SYSTEMS (BOTH VISIBLE AND THERMAL INFARED SPECTRAL BANDS) IN ORDER TO ABET CLOUD ANALYSIS AND INTERPRETATION. SENSORS OF INTEREST INCLUDE THE DMSP OLS, NOAA AVHRR, GOES VISSR, AND LANDSAT TM/MSS. SALIENT SENSOR CHARACTERISTICS WILL BE IDENTIFIED, SAMPLE DATA SETS SELECTED AN ...

RECENTLY, RESEARCH AT SEVERAL GOVERNMENT FACILITIES HAS RESULTED IN SIGNIFICANT ADVANCES IN BOTH THE ELECTRONIC AND DETECTOR ASPECTS OF INTEGRATING RADIATION DOSIMETERS. ONE PARTICULAR APPROACH, THE LOS ALAMOS MULTIDETECTOR RADIATION MONITOR, IS A MICROPROCESSOR BASED INSTRUMENT, CAPABLE OF INTERROGATING SEVERAL DIFFERENT NUCLEAR DETECTORS SIMULTANEOUSLY. ALTHOUGH USING GEIGER TUBES FOR THE GAMMA ...

THE ADVENT OF FIBER REINFORCED COMPOSITES HAS MADE AVAILABLE NEW STRUCTURAL MATERIALS FOR USE IN MILITARY HARDWARE. IN PARTICULAR, ARMOR PANELS MADE FROM FIBERGLASS REINFORCED PLASTICS PROVIDE STRENGTH TO WEIGHT RATIOS SIGNIFICANTLY SUPERIOR TO THOSE MADE FROM METAL PLATE. THESE NEW MATERIALS ARE CRITICAL FOR MAXIMIZING THE PERFORMANCE OF MODER MILITARY ARTICLES SUCH AS HIGH SPEED TANKS AND TROOP ...

EXISTING MULTIPLE-AIRCRAFT AIR COMBAT SIMULATION MODELS GENERALLY RELY ON SIMPLIFIED TACTICS BASED ON RELATIVE POSITIONS. THE OBJECTIVE OF THE PHASE I STUDY IS TO DETERMINE THE POTENTIAL OF INNOVATIVE TECHNIQUES FOR BUILDING A MORE REALISTIC TACTICS GENERATION MODULE ADAPTIVE TO EXISTING SIMULATION MODELS. THE APPROACH INVOLVES: (1) CLARIFICATION OF THE OVERALL AIR BATTLE MANAGEMENT STRUCTURE, WIT ...

THE PROJECT WILL DEFINE THE CAPABILITIES AND DETERMINE THE COST TO DEVELOP A TRANSPORTABLE, REALTIME DYNAMIC SIMULATOR SYSTEM WITH THE FOLLOWING FEATURES: A) DENSE, PULSE-BY-PULSE ENVIRONMENT; B) C3 SYSTEM MODELS FOR BOTH ATTACKER AND DEFENDER FORCES; C) INTERACTIVE PARTICIPATION OF UP TO E.G., 6 PILOTS TO CONTROL THEIR AIRCRAFT, ASSOCIATED AVIONICS AND MISSILE SYSTEMS; D) INTERACTIVE PARTICIPATIO ...

A NOVEL APPROACH TO THE SAFETY OF RESERVE BATTERIES IS TAKEN, BASED ON A BATTERY DESIGN THAT ELIMINATES THE USE OF A SEPARATE RESERVOIR TO STORE THE ELECTROLYTE DURING INACTIVE LIFE OF THE BATTERY. CELLS WITHOUT THE ELECTROLYTE AND THE ELECTROLYTE ITSELF ARE SITUATED IN A BATTERY CONTAINER, STORED UNDER VACUUM. THE BATTERY IS ACTIVATED SIMPLY BY ADMITTING THE AIR INTO THE CONTAINER. THE AIR FORCES ...

CURRENT EXTINGUISHMENT TECHNIQUES CAN UTILIZE DRY CHEMICAL AND AQUEOUS FOAMS TO KNOCKDOWN A POOL FIRE IN AN AIRCRAFT FIRE INCIDENT. AS NEW FUEL IS ADDED, DUE TO SPILLS, REIGNITION AND FLASHBACK IS POSSIBLE. MECHANISMS BASED ON COMBUSTION REACTION AND VAPORIZATION PROCESSES WILL BE SCREENED TO DETERMINE CANDIDATE MECHANISMS TO PREVENT OR NEUTRALIZE FUEL ENTERING THE FIRE ZONE. BASED ON MECHANISMS D ...

AIRPLANE FOREBODY DESIGN HAS CONSISTENTLY DEMONSTRATED SIGNIFICANT INFLUENCES ON BOTH STATIC AND ROTATIONAL AERODYNAMICS AND, CONSEQUENTLY, ON HIGH ANGLE-OF-ATTACK FLIGHT CHARACTERISTICS AND SPIN BEHAVIOR. AN EXTENSIVE HIGH ANGLE-OF-ATTACK DATA BASE FOR MILITARY CONFIGURATIONS HAS BEEN GENERATED USING THE ROTARY BALANCE AT THE NASA LANGLEY 20-FOOT SPIN TUNNEL. THIS DATA BASE WILL BE UTILIZED TO CO ...

THERMALLY ACTIVATED LITHIUM ALLOY - IRON PYRITE BATTERIES ARE USED IN A VARIETY OF MILITARY APPLICATIONS. THESE BATTERIES EXHIBIT ABNORMALLY HIGH VOLTAGES DURING THE FIRST SEVERAL MINUTES OF DISCHARGE. THE VOLTAGE TRANSIENT HAS BEEN ASSOCIATED WITH THE PHYSICAL AND CHEMICAL PROPERTIES OF THE NATURALLY OCCURRING PYRITE USED IN THE CATHODE. THIS PROGRAM SEEKS TO DEMONSTRATE THAT HIGH PURITY SYNTHETI ...
