A DESIGN PHASE PROGRAM IS PROPOSED FOR THE DEVELOPMENT OF A PROCESS AND EQUIPMENT FOR USE IN FREQUENCY CONTROL OF PULSED LASERS TO ACHIEVE VERY HIGH FREQUENCY STABILITY ( 1 IN 10 TO THE 10TH POWER OR 10 TO THE 11TH POWER). THERE EXISTS A VARIETY OF IMPORTANT LASER RADAR APPLICATIONS FOR WHICH ENERGETIC LASER PULSES ARE NEEDED AT A FREQUENCY STABILITY AT THIS LEVEL. THE EXISTING METHOD TO ACHIEVE S ...

ORDERED POLYMER FILMS PROCESSED FROM POLYPHENYLENE BENZOBISTHIAZOLE WILL BE MADE, TESTED AND EVALUATED FOR USE IN LIGHTWEIGHT HIGH PERFORMANCE CAPACITORS FOR AIRBORNE AND SPACEBORNE APPLICATIONS WITH ENERGY STORAGE OVER 3000 JOULES PER KILOGRAM. SPACE CHARGE SHIELDING NEAR THE ELECTRODES WILL BE USE TO PREVENT DIELECTRIC BREAKDOWN AT THE ELECTRODE INTERFACE.

THE INTENT OF THIS PROJECT IS TO PROVIDE A SOFTWARE ENVIRONMENT WHICH WILL ALLOW IMMEDIATE IMPLEMENTATION OF A VARIETY OF COOPERATING EXPERT SYSTEM PARADIGMS. THE ENVIRONMENT, REFERRED TO AS ACCESS, WILL BE DESIGNED TO BE EXPERT SYSTEM REPRESENTATION INDEPENDENT, BE PORTABLE TO ANY HARDWARE WHICH SUPPORTS COMMON LISP, PROVIDE A FLEXIBLE MESSAGE PASSING PROTOCOL AND ALLOW THE USER TO ARRANGE EXPERT ...

A COMPUTER CODE WILL BE DEVELOPED TO PROVIDE TWO-DIMENSIONAL NONEQUILIBRIUM SOLUTIONS FOR REENTRY VEHICLE BOUNDARY LAYERS, WITH EMPHASIS ON PREDICTION OF THE ELECTRON DENSITY. A BLOCK IMPLICIT TECHNIQUE WILL BE IMPLEMENTED FOR RELIABLE, STABLE SOLUTION OF THE CHEMICAL KINETIC RATE EQUATIONS AT ALL REENTRY ALTITUDES. THE CODE WILL BE CAPABLE OF HANDLING A WIDE VARIETY OF CHEMICAL SYSTEMS (AIR, HYDR ...

A SPATIAL LIGHT MODULATOR SENSITIVE IN THE INFRARED AND AT SAME TIME PROVIDING THE CAPABILITY OF MODULATING A LASER BEAM IN THE VISIBLE SHALL BE OF GREAT VALUE IN OPTICAL INFORMATION PROCESSING. THIS PROPOSAL DISCUSSES THE FEASIBILITY OF SUCH A DEVICE UTILIZING HIGH TRANSITION TEMPERATURE SUPERCONDUCTORS IN CONJUNCTION WITH A NONLINEAR OPTICAL MATERIAL. THE NONLINEARITY EXPLOITED FOR THESE DEVICES ...

A NONMETALLIC MATERIAL IS PROPOSED THAT CAN BE USED TO MANUFACTURE COATINGS OR COMPLETE SECTIONS OF HEAT EXCHANGERS WHICH ARE SUBMERGED IN SALTWATER FOR LONG PERIODS OF TIME. THE PROPOSED MATERIAL SHOULD BE RESISTANT TO THE SEAWATER EXPOSURE AND AT THE SAME TIME HAVE A THERMAL CONDUCTIVITY EXCEEDING 30 W/M-OC.

A SMART AEROSPACE STRUCTURE WHICH CAN DETECT AND ISOLATE STRUCTURAL DAMAGE IN REAL-TIME AND PROVIDE ON-LINE RECONFIGURATION OF THE STRUCTURE'S CONTROL SYSTEM UNDER THE DETECTED IMPAIRMENT CONDITIONS WOULD SIGNIFICANTLY BOOST THE RELIABILITY, MAINTAINABILITY AND PERFORMANCE OF CURRENT AND PROPOSED AIR FORCE FLIGHT AND SPACE VEHICLES. HERE, WE PROPOSE TO INVESTIGATE AND DEFINE A SMART AEROSPACE STRU ...

THERE IS PRESENTLY A NEED TO INCREASE THE CURRENT CARRYING CAPABILITIES OF THE NEW HIGH TEMPERATURE, CERAMIC SUPERCONDUCTORS. UNLESS HIGHER CRITICAL CURRENTS ARE ACHIEVED IN BULK SUPERCONDUCTING MATERIALS, THE PRESENT CLASS OF MATERIALS WILL NOT MEET THE REQUIREMENTS OF MANY ANTICIPATED APPLICATIONS. THE GOAL OF THE PHASE I PROGRAM IS THE SYNTHESIS OF A CRYSTALLOGRAPHICALLY ORIENTED YBA(2)CU(3)O(7 ...

STRATEGIC DEFENSE COMPUTING NEEDS CALL FOR MASSIVELY PARALLEL DATA PROCESSING FOR BATTLE MANAGEMENT, AND THE ABILITY TO GO BEYOND NUMERICAL CALCULATIONS TO DIRECT SYMBOLIC PROCESSING. A NEW APPROACH TO ALL-OPTICAL COMPUTING IS BEING STUDIED BASED ON A CELLULAR AUTOMATON ARCHITECTURE NEVER BEFORE DEMONSTRATED IN AN ALL-OPTICAL CONTEXT. TO MAKE THIS POSSIBLE, THE NONLINEAR TRIPLE PROCESSOR DEVICEIS ...

PRECISION POINTING OF LARGE PAYLOADS REQUIRES TORQUES AND ANGULAR MOMENTUM STORAGE CAPACITIES THAT ARE LARGE IN COMPARISON TO THE CAPABILITIES OF AVAILABLE HARDWARE. IN ADDITION, THE POINTING ACTUATOR MUST HAVE EXTREMELY LOW TORQUE JITTER. HIGH TORQUE AND LOW NOISE COMBINE TO PRODUCE AN EXTREMELY DIFFICULT DESIGN CONSTRAINT FOR MECHANICAL BEARINGS SINCE ROLLING ELEMENTS TRANSMIT VIBRATIONS DIRECTL ...
