NAVY TECHNICAL REQUIREMENTS FOR INSENSITIVE MUNITIONS, NAVSEAINST 8020.5, STATES THAT "BURNING" IS THE ONLY ACCEPTABLE REACTION TO THE MIL-STD-2105 SLOW COOK-OFF TEST. TYPICAL REACTIONS IN THIS TEST ARE DETONATIONS OR PARTIAL DETONATIONS. ENERGETIC MATERIALS EXPOSED TO ELEVATED TEMPERATURES, UNDERGO A SLOW CHEMICAL REACTION, FINALLY REACHING A POINT OF AUTOCATALYTIC DECOMPOSITION, RESULTING IN VER ...

OPTICAL COMMUNICATION LINKS HAVE SEVERAL ADVANTAGES FOR SHIP-TO-SHIP APPLICATIONS. KEY FEATURES WHICH MAKE OPTICAL COMMUNICATION ATTRACTIVE INCLUDE HIGH DATA BANDWIDTH AND EASE OF PROTECTION FROM INTERCEPTION. THE PERFORMANCE REQUIREMENTS FOR POINTING AND TRACKING SYSTEMS FOR OPTICAL COMMUNICATION LINKS ARE DEMANDING WHEN EITHER TRANSMITTER OR RECEIVER IS ON A MOVING VEHICLE. CONSEQUENTLY, SUCH SY ...

THE INTENT OF THIS WORK IS TO DEVELOP AN ADVANCED ESTIMATION ALGORITHM FOR MANEUVERING TARGET STATE ESTIMATION AND PREDICTION. THE ALGORITHM WILL BE USED FOR FIRE CONTROL IN THE LOCAL AREA DEFENSE ROLE. THE TARGET STATE ESTIMATOR USES TWO DIMENSIONAL INFRA-RED ELECTRO-OPTICAL IMAGERY AND RADAR DATA TO COMPUTE CURRENT AND PREDICT FUTURE TARGET STATES. INCLUDED IN THIS ANALYSIS WILL BE ALGORITHMS FO ...

THE SEEMINGLY IMPOSSIBLE TASK OF PRODUCING ONE-HALF OF A MEGAWATT OF ACOUSTIC POWER UNDERWATER AT A FREQUENCY OF 5 HZ IS ADDRESSED. THE EXPLOITATION OF THE RECENT INTRODUCTION OF NEW RARE EARTH PERMANENT MAGNET MATERIALS, THE CONCEPT OF USING A FLEXURAL DISC RADIATOR, AND THE RECENT CULMINATION OF TWO YEARS OF ELECTRODYNAMIC TRANSDUCER DEVELOPMENT IS PROPOSED. THE USE OF MATHEMATICAL MODELING, EXP ...

MOVING-COIL TRANSDUCERS ARE USUALLY ASSOCIATED WITH LOW POWER, LOW EFFICIENCY, BROADBAND AND VERY LOW FREQUENCY APPLICATIONS. THE RECENT INTRODUCTION OF RARE EARTH PERMANENT MAGNETIC MATERIALS HAVING HIGH ENERGY DENSITIES AND THE RECENT DEVELOPMENT OF BETTER DESIGN TECHNIQUES SIGNIFICANTLY IMPROVE EFFICIENCY, POWER HANDLING ABILITY, AND HIGH FREQUENCY OPERATION. THE APPLICATION OF THESE IMPROVEMEN ...

NUMEROUS STUDIES CONDUCTED IN THE PAST HAVE CLEARLY ESTABLISHED THE STRONG CORRELATION BETWEEN THE MICROSTRUCTURE AND THE ENERGETIC PROPERTIES OF SOLID PROPELLANTS SUCH AS RDX,HMX, AL, NH(4)CL0(4), ETC. THE PRESENT STUDY WILL EXAMINE THE FEASIBILITY OF USING A NONCONTACT, NON-DESTRUCTIVE X-RAY TECHNIQUE DEVELOPED UNDER CURRENT ONR SPONSORSHIP FOR SUCCESSFULLY CHARACTERIZATING SOLID PROPELLANT COMP ...
