STEP BY STEP PROCEDURES WILL BE DEVELOPED WHICH PROVIDE FOR THE DETAILED EVALUATION OF ELECTRONIC, MECHANICAL AND PYROTECHNIC DEVICES WITH RESPECT TO THE EFFECTS OF LONG TERM STORAGE. THESE PROCEDURES WILL PROVIDE FOR THEORETICAL (PAPER) EVALUATIONS OF THESE ELEMENTS, AS WELL AS STORAGE CONTAINERS, SPECIFICATIONS, AND PRODUCTION PROCEDURES, WHICH MAY LEAD TO ADDITIONAL PHYSICAL EVALUATIONS AND TES ...

MOST SURFACE COATINGS (PAINTS) USED ON THE EXTERIOR OF MILILTARY HARDWARE POSSESS HIGH THERMAL EMITTANCE IN THE 3 TO 5 MICRON AND 8 TO 23 MICRON WAVELENGTH REGIONS, MAKING THEM VULNERABLE TO DETECTION USING STATE-OF-THE-ART OPTICAL INFRARED DETECTORS. THIS PROPOSED EFFORT HAS AS ITS OBJECTIVE THE DEVELOPMENT OF SURFACE COATINGS THAT HAVE LOW SPECTRAL EMITTANCE PROPERTIES IN THE SENSITIVE WAVELENGT ...

THE DEVELOPMENT OF A NEW MATERIAL TERMED "FIBROUS CARBON" IS PROPOSED. THIS MATERIAL IS FORMED BY THE PLASTICIZATION AND COMPACTION OF STABILIZED POLYACRYLONITRILE FIBERS FOLLOWED BY PYROLYSIS. PREVIOUS WORK HAS SHOWN GOOD TRANSLATION OF AXIAL FIBER PROPERTIES INTO THE FIBROUS CARBON. THIS PROPOSAL ADDRESSES THE DEVELOPMENT OF IMPROVED SHEAR PROPERTIES IN CARBON BASED MATERIALS NEEDED FOR AIR FORC ...

A SUBSTANTIAL AMOUNT OF THERMAL PROTECTION SYSTEM (TPS) MATERIAL CAN BE REMOVED BY ABLATIVE AND MECHANICAL EROSION. THIS CAN CAUSE CATASTROPHIC FAILURE OR STABILITY AND ACCURACY PROBLEMS OF REENTRY VEHICLES. THE TPS MUST BE ABLE TO PROTECT THE SUBSTRUCTURE AND INTERNAL COMPONENTS FROM DAMAGE INCURRED BY AERODYNAMIC HEATING AND PARTICLE IMPACT BUT NOT SUFFER WEIGHT PENALTIES ASSOCIATED WITH "OVERKI ...

THE EXCELLENT PROPERTIES OF CARBON-CARBON (C/C) COMPOSITES MAKE THESE MATERIALS PRIME CANDIDATES FOR HIGH TEMPERATURE RESISTANT STRUCTURES ON ADVANCED MISSILES. HOWEVER, C/C COMPONENTS MUST BE JOINED TOGETHER TO PRODUCE A FINAL STRUCTURE. THE USE OF ADHESIVE BONDING AND METALLIC FASTENERS IS NOT PRACTICAL AT HIGH TEMPERATURES. THE MOST DESIRABLE FASTENER TO JOIN C/C COMPOSITES TOGETHER WOULD BE FA ...

THE PROPOSED PROGRAM OFFERS AN INNOVATIVE APPROACH FOR PROTECTING A BATTLE GROUP FROM ATTACKS BY ADVANCED ANTI-SHIP MISSILES. SPACIALLY DISTRIBUTED COUNTERMEASURES, OF VARIOUS TYPES, ARE DEPLOYED IN A COORDINATED MANNER SO AS TO COUNTER ALL PHASES AND ASPECTS OF THREAT MISSILE WEAPON SYSTEMS. THESE COORDINATED COUNTERMEASURES TECHNIQUES ARE APPLIED SEQUENTUALLY AND THEIR EFFECTIVENESS AGAINST EACH ...

A NOVEL SIGNAL PROCESSING AND PHONETIC ANALYSIS SYSTEM OPERATING IN THE TIME DOMAIN IS PROPOSED WHICH AVOIDS THE COSTLY AND TIMECONSUMING MATHEMATICAL SOFTWARE FILTERING SCHEMES OFTEN USED. THE PITCH SYNCHRONOUS RATIOMETRIC FACTORS REPRESENTING PHONEMIC ELEMENTS OF SPEECH ARE SEPARATED FROM THE SPORADIC NOISE AND CERTAIN PERSONALITY VARIABLE FEATURES. THE PURIFIED STRING OF ENCODED PHONETIC ELEMEN ...
