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 ...

DEFINITIONS ARE REQUIRED OF STRUCTURAL WEIGHT FRACTIONS FOR DELTOID AEROBODY PLATFORMS IN ORDER TO ASSESS THEIR POTENTIAL. PRIOR DATA ON CONVENTIONAL AIRPLANES AND ZEPPELINS CANNOT BE INTERPOLATED OR EXTRAPOLATED WITH CONFIDENCE TO PROVIDE THE REQUIRED DEFINITION. THEREFORE, STRUCTURAL DESIGN STUDIES WILL BE MADE ESPECIALLY FOR THIS SHAPE, MASS DISTRIBUTION AND AIRLOAD. MODERN HIGH-STRENGTH AND ST ...

BROADCOM HAS DEVELOPED AN AUTOMATIC LOCATING, TRACKING AND MULTIPLE BEAM MICROWAVE COMMUNICATION SYSTEM WHICH IT HAS PRESENTED TO ESD WITH HIGH POSITIVE RESPONSE. A MAJOR ISSUE IS THE JAM IMMUNITY OF THE SYSTEM AGAINST THE ANTICIPATED THREAT. THIS EFFORT WILL INVOLVE THREE PHASES, THE ESTABLISHMENT OF THE THREAT, THE EVALUATION OF THE THREAT AGAINST AT LEAST TWO SYNAPSISTEM ARCHITECTURES AND A RED ...

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 ...

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 ...

THIS PROPOSAL ADDRESSES THE DEVELOPMENT OF AN INTELLIGENT TUTORING SYSTEM (ITS) TO TRAIN AIR FORCE PERSONNEL. EXPERT-EASE SYSTEMS (EES) HAS DEVELOPED AND DEMONSTRATED A SUCCESSFUL COMPUTER-BASED INSTRUCTION TECHNIQUE CALLED OPTIMALLY ADAPTIVE LEARNING (OAL). OAL COMBINES SEVERAL TECHNOLOGIES: OPTIMIZATION THEORY, EDUCATIONAL MODELING, AND HUMAN PSYCHOLOGY. THE OAL APPROACH UTILIZED ADVANCED OPTIMI ...

THE EXPERIENCE OF THE PAST THIRTY YEARS IN THE SPACE BUSINESS HAS YET TO BE FULLY EXPLOITED FOR ITS POTENTIAL IN REDUCING SPACE SYSTEMS COSTS. THE PROPOSED EFFORT WILL PROVIDE A METHODOLOGY WHICH WILL PLACE THE PAST EXPERIENCE OF COST REDUCTION INITIATIVES AT THE FINGERTIPS OF THE AIR FORCE MANAGERS. THE METHODOLOGY IS PLANNED TO TAKE THE FORM OF A TWO PART DECISION SUPPORT MODEL CODED FOR A PERSO ...

THE PROPOSED PROJECT WILL DEVELOP INNOVATIVE TECHNIQUES FOR LOW-COST CONTROL OF THE ATTITUDE AND ENGINE FIRING OF THE ELECTRIC ORBITAL TRANSFER VEHICLE (EOTV) DURING ITS SPIRAL ORBIT TRANSFER MISSION. THE EOTV PROMISES THE ABILITY TO DELIVER GPS REPLENISHMENT SATELLITES TO THEIR OPERATIONAL ORBITS AT SIGNIFICANT COST SAVINGS OVER CONVENTIONAL CHEMICAL UPPER STAGES. THE PROPOSED APPROACH WILL USE T ...

THE MANUFACTURE OF POLYMER MATRIX COMPOSITES AND PLASTICS INVOLVES COMPLEX CHEMICAL AND PHYSICAL CHANGES THAT MUST BE MONITORED AND CONTROLLED TO YIELD DESIRED PRODUCTS. AT MICROWAVE FREQUENCIES, BOTH THE DIELECTRIC (E') AND ABSORPTIVE (E") PROPERTIES ARE EXCELLENT DIAGNOSTIC INDICATORS OF THE CURE STATE. THE OBJECTIVE OF THIS RESEARCH IS TO DEMONSTRATE THE FEASIBILITY OF USING MICROWAVE OPEN-ENDE ...
