A PLAN FOR THE DEVELOPMENT OF A MESOSCALE WEATHER NOWCASTING SYSTEM IS PROPOSED. THAT SYSTEM WOULD BE USED AS A TACTICAL DECISION AID FOR SUPPORT OF TACTICAL ARMY OPERATIONS. THE SYSTEM WOULD BE COMPOSED OF MODULAR SENSOR PACKAGES, A TELEMETRY SYSTEM, A FLEXIBLE SYSTEM OF SENSOR DEPLOYMENT, AND A MICROPROCESSOR BASED TACTICAL COMPUTER SYSTEM FOR THE ANALYSIS AND DISPLAY OF DATA COLLECTED. THE PROP ...

N/A

THIS PROPOSAL WILL DEMONSTRATE (IN 2" TO 4" SIZE), A NOISE REUCING TRIM THAT CAN BE UTILIZED IN ROTARY CONTROL/ON-OFF BALL VALVES. THIS VALVE TRIM ADDRESSES NOISE AT THE SOURCE. THE BASIC DESIGN HAS A VARIABLE IMPEDENCE TRIM TO CAUSE A HIGH IMPEDENCE AT LOW ANGLES OF OPENING AND LOW IMPEDENCE (VERY LITTLE FLOW RESTRICTION) AT LARGE OPENING ANGLES. IT IS AN IDEAL VALVE FOR PRESSURIZATION/DE-PRESSUR ...

N/A

CONTRACTOR WILL DEVELOP A LAGRANGIAN FORMULATION FOR THE ELECTROMAGNETIC RESPONSE OF A METALLIC ENCLOSURE WITH THIN, SLIGHTLY DIFFUSIVE WALLS AND A WIRE SPANNING THE ENCLOSURE. CONTRACTOR WILL FIRST DERIVE A LAGRANGIAN OPERATOR ON THE FIELDS WHICH IS STATIONARY WHEN MAXWELL'S EQUATIONS ARE SATISFIED. THE LAGRANGIAN WILL THEN BE USED TO DETERMINE THE ENCLOSURE EIGENMODES (WIRE INCLUDED) AND THE AMP ...

CODES CURRENTLY EXIST THAT WILL CALCULATE THE ELECTROMAGNETIC ENVIRONMENT (EMP) PRODUCED BY A BEAM OF COLLIMATED GAMMA RAYS. THE COLLIMATION MAY BE EITHER CYLINDRICAL OR CONICAL. THE CURRENT EFFORT WILL BE TO INSTALL THE CODES ON AN ARMY CRAY COMPUTER AND TO SET THEM UP AND RUN THEM FOR PROBLEMS OF INTEREST TO THE ARMY.

THERE IS AN ESTABLISHED NEED FOR A SIMPLE ROBUST TRANSDUCER TO MEASURE PARTICLE VELOCITY IN SEVERE BLAST AND SHOCK ENVIRONMENTS SUCH AS NUCLEAR AND HIGH EXPLOSIVE TESTS. A GAGE CONCEPT IS PROPOSED FOR DEVELOPMENT, BASED ON THE PROVEN MEASUREMENT PRINCIPLES USED IN THE HIGHLY SUCCESSFUL DX GAGE, BUT RECONFIGURED MECHANICALLY AND ELECTRICALLY TO WITHSTAND THE HARSH SHOCK ENVIRONMENTS. THE CONCEPT RE ...

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 ...
