THE TREND CONTINUES TOWARDS APPLYING ADVANCED COMPOSITE MATERIALS TO THE HIGH PERFORMANCE STRUCTURES ASSOCIATED WITH AEROSPACE. STRUCTURES FABRICATED FROM CARBON-CARBON AND FILAMENT WOUND COMPOSITES ARE PARTICULAR EXAMPLES. TO FULLY EXPLOIT THE PROMISE OF THESE ADVANCED STRUCTURES, NOVEL NDE TECHNIQUES ARE NEEDED FOR CHARACTERIZATION. DUAL-ENERGY LAMINOGRAPHY SPECIFICALLY ADDRESSES THE CHEMICAL, D ...

THE COMPUTATIONALLY INTENSE NATURE OF BLADE ELEMENT ROTORCRAFT MATH MODELS HAS LIMITED THEIR USE IN REAL-TIME SIMULATIONS TO LARGE MAINFRAME COMPUTERS OR SPECIAL PURPOSE COMPUTER SYSTEMS. BLADE ELEMENT MODELS ARE, HOWEVER, NECESSARY TO ACCURATELY REPRODUCE THE ROTORCRAFT RESPONSE DURING COMPLEX MANUEVERS, SUCH AS THOSE REQUIRED FOR COMBAT. THE RECENTLY RELEASED DEC MICROVAX II COMPUTER HAS THE CAP ...

THIS PROPOSAL PROVIDES AN INNOVATIVE APPROACH TO COUNTERING PARAMETER AGILE RADAR SYSTEMS USING A UNIQUE METHOD FOR SIGNAL TRACKING AND A KNOWLEDGE BASED SIGNAL FUNCTION RECOGNITION SYSTEM.

MONOCRYSTALLINE SUBSTRATE OF CDZNTE (4 AT% ZN), NOMINALLY LATTICE MATCHED TO HGCDTE (20 AT% CD), WILL BE PREPARED FROM CRYSTALS GROWN BY A NEW PROCESS. THE NEW CRYSTAL GROWTH SYSTEM IS FREE OF QUARTZ AND PROVIDES IMPROVED GROWTH CONDITIONS THROUGH 1) TEMPERATURE PROFILING AND PRESSURE CONTROL TECHNIQUES THAT CANNOT BE USED IN CONVENTIONAL GROWTH SYSTEMS BECAUSE OF TEMPERATURE AND PRESSURE LIMITATI ...

CDTE NUCLEAR PARTICLE DETECTORS WILL BE MADE FROM CRYSTALS GROWN BY A NEW PROCESS THAT USES A QUARTZ-FREE SYSTEM PROVIDING IMPROVED GROWTH CONDITIONS THROUGH 1) TEMPERATURE PROFILING AND PRESSURE CONTROL TECHNIQUES THAT CANNOT BE USED IN CONVENTIONAL GROWTH SYSTEMS BECAUSE OF TEMPERATURE AND PRESSURE LIMITATIONS ON QUARTS AND 2) REMOVAL OF A NUMBER OF SIGNIFICANT CONTAMINATION PROBLEMS RELATED TO ...

THE FEASIBILITY OF AN ARTIFICIAL INTELLIGENCE SYSTEM FOR UNMANNED AIR VEHICLE (UAV) MISSION PLANNING, NAVIGATION WAYPOINT SELECTION AND INTEGRATED ESM/EO PAYLOAD OPERATIONS WILL BE DEMONSTRATED VIA RAPID PROTOTYPING. THE MISSION PLANNING ALGORITHM WILL RECOGNIZE CONFLICTS AMONG MILITARY/OPERATIONAL REQUIREMENTS WHICH ARE COMPETING FOR AVAILABLE UAV RESOURCES; A SYSTEM OF RULES WILL BE APPLIED TO R ...

THE RESEARCH ADDRESSED IN THIS PROPOSAL INVOLVES AN INVESTIGATION INTO THE USE OF DIAMOND THIN FILMS AS SOLID STATE OPTICAL SWITCHES WHERE THE FILMS ARE PRODUCED BY AN INHERENTLY LOW-COST TECHNIQUE EMPLOYING PLASMA-ENHANCED CHEMICAL VAPOR DEPOSITION (PE-CVD) OF CARBON-CONTAINING GASES (E.G., METHANE). THE OBJECTIVE OF THIS PROPOSED RESEARCH EFFORT IS TO EVALUATE EXPERIMENTALLY THE OPTOELECTRIC PRO ...

THE OBJECTIVE OF THIS PROPOSED RESEARCH EFFORT IS TO EXPERIMENTALLY EVALUATE THE OPTOELECTRONIC PROPERTIES OF CHEMICAL VAPOR DEPOSITION DIAMOND THIN FILMS WITH RESPECT TO ELECTROLUMINESCENCE AND PHOTOCONDUCTION IN THE UV AND BLUE-GREEN SPECTRAL REGIONS. AS A RESULT OF SUCH EFFORTS WE WILL DETERMINE THE EXTENT TO WHICH DIAMOND THIN FILMS MAY BE USED AS LASING MEDIA OR PHOTOCONDUCTORS AND ASCERTAIN ...

THE DEFENSE TRANSPORTATION SYSTEM NETWORK HAS MANY NODES EXTENDING FROM THE SHIPPER TO THE OVERSEAS FIELD COMBAT COMMANDER. IN A MAJOR DEPLOYMENT OF U.S. FORCES TO A THEATER OF OPERATIONS APPROXIMATELY 95% OF UNIT COMBAT EQUIPMENT SUSTAINING SUPPLIED AND RESUPPLY ARE TRANSPORTED BY CARGO SHIPS. THE MOST DEMANDING WAR SCENARIOS ASSUME THAT FIXED SEAPORT DISCHARGE FACILITIES ARE DENIED. CARGO DISCHA ...

STORAGE OF ELECTRICAL ENERGY AT A SUFFICIENTLY HIGH DENSITY, IN A SMALL ENOUGH VOLUME AND WITH HIGH ENOUGH EFFICIENCY OF EXTRACTION IS INCRESINGLY BECOMING A SIGNIFICANT PROBLEM. CONVENTIONAL CAPACITIVE DEVICES (E.G., ELECTROLYTIC CAPACITORS) FALL SHORT OF PROVIDING THE VOLUMETRIC EFFICIENCY REQUIRED TO SUPPORT NEW TECHNOLOGIES FOR COMPLEX FUZE REQUIREMENTS. WE PROPOSE TO DEVELOP AN ENERGY STORAGE ...
