EXPOSIVES TYPICALLY BEGIN TO DETONATE WHEN HEATED TO TEMPERATURES ON THE ORDER OF 200 DEG C. THUS IT HAS BEEN RECOGNIZED THAT IT WOULD BE VERY DESIRABLE TO INCREASE THE TIME AT WHICH WEAPONS REMAIN BELOW ABOUT 150 DEG C, EVEN IF THIS INCREASE IS ONLY A FEW MINUTES. COATINGS HAVE BEEN DEVELOPED WHICH MAINTAIN WEAPON TEMPERATURES BELOW 200 DEG C FOR ALMOST FIVE MINUTES EVEN WHEN THE WEAPON IS EXPOSE ...

INCREASINGLY STRINGENT INDUSTRIAL SAFETY STANDARDS AND ENVIRONMENTAL REGULATIONS ARE RESTRICTING THE USE OF ORGANOMETALLIC BASED PAINT WITH THE RESULT THAT THE NAVY NOW HAS POORER QUALITY ANTIFOULING PAINT PERFORMANCE THAN IT HAD PRIOR TO RECENT DEVELOPMENTS. THIS PROPOSAL INVOLVES EXPLORING AN ENTIRELY NEW APPROACH TO ANTIFOULING PAINTS WHICH MAY PRODUCE ANTIFOULING SURFACES WITHOUT THE USE OF EX ...

WHILE THE THEORETICAL BOUNDS ON THE ENERGY STORED BY AND THE POWER OUTPUT OF ELECTROCHEMICAL POWER SOURCES ARE WELL DEFINED BY THERMODYNAMIC AND PHYSICAL CONSIDERATIONS, THE DEGREE TO WHICH ONE CAN APPROACH THE THEORETICAL BOUNDS IS DETERMINED BY CONTRAINTS IMPOSED BY THE DESIGN OF THE ELECTRODES AND PACKAGING MATERIALS. THIS RESEARCH DEALS WITH AN INNOVATIVE CONCEPT FOR MATERIALS AND PACKAGE DESI ...

THERMALLY ACTIVATED LITHIUM ALLOY - IRON PYRITE BATTERIES ARE USED IN A VARIETY OF MILITARY APPLICATIONS. THESE BATTERIES EXHIBIT ABNORMALLY HIGH VOLTAGES DURING THE FIRST SEVERAL MINUTES OF DISCHARGE. THE VOLTAGE TRANSIENT HAS BEEN ASSOCIATED WITH THE PHYSICAL AND CHEMICAL PROPERTIES OF THE NATURALLY OCCURRING PYRITE USED IN THE CATHODE. THIS PROGRAM SEEKS TO DEMONSTRATE THAT HIGH PURITY SYNTHETI ...

METAL MATRIX COMPOSITES ARE FABRICATED FROM HIGH STRENGTH FIBER OR PARTICLE REINFORCEMENTS AND A SUITABLE MATRIX ALLOY. ALUMINUM COMPOSITES HAVE SHOWN HIGH STRENGTH AND STABILITY AND ARE WELL SUITED TO ADVANCED MILITARY AND CIVIL DESIGN CONCEPTS. REINFORCING FIBERS OFTEN REACT WITH THE MATRIX ALLOY DURING FABRICATION AND PROCESSING FORMING A THIN DIFFUSION REACTION ZONE SURROUNDING THE REINFORCEME ...

ADVANCED AEROSPACE ENGINES AND STRUCTURAL COMPONENTS REQUIRE MATERIALS CAPABLE OF OPERATING IN OXIDIZING ENVIRONMENTS AT 3000 DEG - 40000 DEG F (1650 DEG - 2200 DEG C). TO ACHIEVE THIS OBJECTIVE WILL REQUIRE DEVELOPING ADVANCED COMPOSITE STRUCTURES AND PROTECTING THEM WITH NOVEL COATING SYSTEMS. THIS PHASE I PROPOSAL IS DIRECTED AT EVALUATING A NEW CLASS OF HAFNIUM OXIDE-BASED COATINGS THAT CAN SU ...

THE PRIMARY OBJECTIVE OF THIS STUDY IS TO EVALUATE THE FEASIBILITY OF DEVELOPING A MODEL-BASED METHODOLOGY FOR TERRAIN-FOLLOWING DISPLAY DESIGN AND EVALUATION. THE BASIC APPROACH CENTERS ON THE DEVELOPMENT OF A PILOT/SYSTEM MODEL THAT INTEGRATES GENERAL KNOWLEDGE OF HUMAN PERCEPTION AND PERFORMANCE WITH SPECIFIC KNOWLEDGE OF AIRCRAFT AND AVIONICS CAPABILITIES PECULIAR TO THE TERRAIN-FOLLOWING MISS ...

AS MORE AND MORE WEAPON SYSTEMS EMPLOY CRUCIAL DIGITAL SYSTEMS IN THEIR ARCHITECTURES, COMPUTING SYSTEM RELIABILITY IS BECOMING AN EVER INCREASING PART OF THE OVERALL WEAPON SYSTEMS RELIABILITY. IN CONTRAST TO THE RELIABILITY LEVELS ATTAINED IN COMPUTER HARDWARE, SOFTWARE DEVELOPMENT IS NOT AS ADVANCED. IN FACT, MOST CURRENT SOFTWARE PRODUCTION METHODS DO NOT YIELD SOFTWARE PRODUCTS MEETING THE DE ...
