THE U.S. AIR FORCE HAS AN INTEREST IN HIGH RATE, LOW COST, PRODUCTION PROCESSES FOR AIRCRAFT PARTS. ABARIS PROPOSES A COMBINED ANALYSIS AND TESTING PROJECT TO EXPLORE MODIFYING PRESENT RESIN TRANSFER MOLDING (RTM) TECHNIQUES TO EVALUATE THE FEASIBILITY OF THEIR USE IN THE PRODUCTION OF HIGH PERFORMANCE, AEROSPACE, COMPOSITE MATERIALS. EPOXY RESINS SHALL BE UTILIZED IN COMBINATION WITH GRAPHITE REI ...

THE U.S. ARMY HAS A NEED FOR A LIGHTWEIGHT, STRONG, MOBILE BRIDGE. ONE PROBLEM THAT LIMITS THE PERFORMANCE IS THE DESIGN OF ADHESIVE JOINTS. THIS PROJECT IS TO DEVELOP SEVERAL OPTIMUM JOINT DESIGNS SO THAT THE LOADS ON JOINTS OF EITHER TUBULAR AND FLAT COMPONENTS ARE IN SHEAR, AND THE STRESS CONCENTRATIONS ARE REDUCED. THE PROPOSED PROGRAM IS TO USE THE RESEARCH WE HAVE ACCOMPLISHED IN EXPERT SYST ...

THE USE OF GLOBAL INTERCONNECTS IN DIGITAL OPTICAL COMPUTERSAT THE GATE LEVEL SHOWS THE POTENTIAL TO ACHIEVE GATE INTERCONNECT BANDWIDTH PRODUCTS OF UP TO 10**16 WITH POWER CONSUMPTION ON THE ORDER OF 100W. IN THIS STUDY, METHODS OFHARNESSING THESE INTERCONNECTS FOR WIDEWORD DIGITAL COMPUTATION PRIMITIVES SUCH AS EXCLUSIVE OR, ADD, AND MULTIPLY ARE INVESTIGATED. EFFICIENT IMPLEMENTATION OF THESE P ...

A GENERAL PURPOSE, OPTICAL, VECTOR-MATRIX MULTIPLIER WILL BE DEVISED TO COMPUTE 256X256 ELEMENT MATRICES TIMES 256-ELEMENT VECTORS AT 8-BITS PRECISION IN LESS THAN 100 MICROSECONDS. THIS PROJECT WILL TAKE AN INNOVATIVE ARCHITECTURAL APPROACH THAT USES TWO 64-CHANNEL ACOUSTO-OPTIC DEVICES OPERATING AT SEVERAL HUNDRED MEGAHERTZPER CHANNEL IN A TELECENTRICALLY IMAGED CONFIGURATION. THE USE OF LASER D ...

CHILL AND HEAT STORAGE IS USEFUL IN SHIFTING ELECTRICAL LOAD FROM PERIODS OF PEAK POWER TO OFF-PEAK PERIODS. CHILL STORAGE SYSTEMS USING COMPLEX COMPOUNDS HAVE HIGHER STORAGE DENSITIES (BOTH MASS DENSITY AND VOLUMETRICALLY) THAN CONVENTIONAL SYSTEMS SUCH AS ICE STORAGE, AND CAN BE USED AT LOWER TEMPERATURES. THE COMPOUNDS ADSORB AMMONIA DURING DISCHARGE OF THE CHILL STORAGE AND CAN BE DIRECTLY COU ...

THERMAL STORAGE SYSTEMS ARE NEEDED FOR EFFECTIVE THERMAL MANAGEMENT ON MANNED SPACECRAFT AND PLANETARY BASED SYSTEMS. THERMAL STORAGE EQUIPMENT HAS THE POTENTIAL TO REDUCE THE OVERALL SYSTEM MASS BY DECREASING THE CAPACITY REQUIREMENTS OF HEAT PUMPS, REFRIGERATORS AND CHILLERS THROUGH LOAD LEVELING. TODAY'S THERMAL STORAGE CONCEPTS, HOWEVER, ARE INADEQUATE FOR SPACE APPLICATION, SINCE THE ENERGY D ...

THERMAL ENERGY STORAGE IS USEFUL IN SHIFTING ELECTRICAL LOADFROM PERIODS OF PEAK POWER TO OFF-PEAK PERIODS. THERMAL ENERGY STORAGE SYSTEMS USING COMPLEX COMPOUNDS HAVE HIGHER STORAGE DENSITIES (BOTH MASS AND VOLUMETRIC DENSITY) THAN CONVENTIONAL SYSTEMS. IN THIS PROJECT, A THERMAL ENERGY STORAGE CONCEPT IS ADVANCED TO HEAT WATER FOR DOMESTIC AND COMMERCIAL APPLICATIONS. SEVERAL METHODS EXIST FOR U ...

THE EXHAUST FROM NTO/MMH FUEL RICH GAS GENERATORS (GG) ARE KNOWN TO CONTAIN A LARGE FRACTION OF AMMONIA. THIS PHENOMENON MAKES IT POSSIBLE TO ACTIVELY COOL A ROCKET NOZZLE WALL USING THE ENDOTHERMIC DECOMPOSITION OF AMMONIA. A REALISTIC ANALYSIS OF THIS COMBUSTION PROCESS IS TO BE DEVELOPED WHICH INCLUDES ROCKET NOZZLE FLOW WITH FINITE RATE CHEMICAL KINETICS AND THE TANGENTIAL SLOT INJECTION OF GG ...

THE DEVELOPMENT OF SCREENING MODELS IS PROPOSED TO PROVIDE A TOOL TO DETERMINE THE TRANSFER ABILITY OF RESERVOIR-SPECIFIC RESULTS TO RESERVOIRS IN OTHER FIELDS OR BASINS. A TECHNIQUE UTILIZING CORRELATIONS BETWEEN CHARACTERISTICS OF RESERVOIRS IN DIFFERENT FIELDS AND BASINS WOULD BE RELATED TO PRODUCTION DATA AND COMPLETION TECHNIQUES. STANDARD MODELS WOULD BE DEVELOPED, WITH VARIATIONS, AND A DAT ...
