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 ...

HIGH RANGE (200,000 G) ACCELEROMETERS ARE THE ONLY TRANSDUCERS THAT PROVIDE THE REQUIRED LONG-TERM DATA IN THE ENVIRONMENTS OF INTEREST TO THE BLAST AND SHOCK COMMUNITY. THESE GAGES HAVE A VERY LARGE DYNAMIC RANGE AND NOISE OFTEN MASKS THE LATE TIME (BUT EXTREMELY IMPORTANT) DATA. WE PROPOSE TO DEVELOP A CLOSE COUPLED LOGARITHMIC GAIN SIGNAL CONDITIONING SYSTEM THAT WILL CORRECT THE LATE TIME NOIS ...

"Barrel erosion, which is produced by the combination of hightemperature and pressure with aggressive propellant combustionproducts, and the action of the projectile, results in decreasedmuzzle velocities, increased projectile yaw, and decreasedaccuracy. New material designs are needed to mitigate erosion ingun barrels, which limits service lifeCeramic composites are a leading material candidate ...

THIS PROGRAM IS ORGANIZAED TO DEMONSTRATE THE FEASIBILITY OF USING A GASEOUS TRITIUM LIGHT SOURCE (GTLS) AS A SELF POWERED DEVICE TO PROVIDE CONTINUOUS ILLUMINATION INSIDE A ROCKET MOTOR ARM-FIRE DEVICE FOR A PERIOD OF 15 YEARS. THE SOURCE WILL ILLUMINATE SAFE/ARMED (S/A) SYMBOLS WITH COLOR CODED LIGHT. AN IMAGE QUALITY FIBER OPTIC BUNDLE WILL ALLOW THE IMAGE OF THE INDICATOR TO BE OBSERVED BY ORD ...

SPS SHALL UNDERTAKE AND R&D EFFORT TO INVESTIGATE THE FEASIBILITY AND EFFECTIVENESS OF AN "INTELLIGENT EXPERT ASSISTANT" WHICH APPLIES EXPERT SYSTEM TECHNOLOGY IN CONJUNCTION WITH COMPUTER-AIDED SOFTWARE ENGINEERING (CASE) TOOLS FOR STRUCTURED SOFTWARE DEVELOPMENT. THE RESEARCH OBJECTIVE IS TO SHOW THAT HIGHER-QUALITY, FASTER, AND MORE EFFICIENT SOFTWARE DEVELOPMENT IS ACHIEVABLE WITH AN EXPERT SY ...

CONAX HAS EXTENDED THE EXPERIENCE GAINED IN 14 YEARS OF ENGINEERING AND MANUFACTURING ELECTRICAL PENETRATORS TO SEALING DEVICES FOR FIBER OPTICS. FIBER OPTIC PENETRATORS WITH A TOTAL OPTICAL LOSS OF 0.3 DB AT 10,000 PSI HAVE BEEN DEMONSTRATED. AN INNOVATIVE USE OF COMPRESSIVE SEALING IS PROPOSED TO DEVELOP A PENETRATOR FOR SINGLE MODE FIBER WHICH IS MORE RUGGED AND HAS A WIDER OPERATING TEMPERATUR ...

An existing 3D Eulerian code for computing incompressible flows will be enhanced to enable underwater explosion simulations, focusing especially on free-field bulk cavitation, bubble growth and collapse, and bubble jetting. The emphasis will be onimproving the accuracy and efficiency of the code's algorithms for simulating underwater shock. Currently the code includes level set methods, adaptive m ...

A NEW APPROACH TO PHASED ARRAY ANTENNA DESIGN IS PROPOSED, BASED ON UNPUBLISHED WORK AT EMA, WHICH PREDICTS THE POSSIBILITY OF PRODUCING GIGAWATTS OF EFFECTIVE RADIATED POWER. PRELIMINARY PREDICTIONS BASED ON THE NEW DESIGN CONCEPTS INDICATE AS MUCH AS 80 DB INCREASE IN POWER OVER CONVENTIONAL PHASED ARRAY DESIGNS MAY BE ACHIEVABLE. EMA'S CONCEPTS ALLOW ENERGY TO BE STORED ON THE ANTENNA THROUGH A ...

FIBER OPTIC TECHNOLOGY IS DISPLACING ELECTRICAL WIRING IN MANY APPLICATIONS. THE TREND IN FIBER OPTICS IS CLEARLY TOWARDS THE SINGLE-MODE TYPE VERSUS THE MULTIMODE TYPE. THIS PRESENTS A PROBLEM IN BUILDING COUPLINGS FOR SINGLE MODE FIBERS, SIMPLY BECAUSE THE CORESARE MUCH SMALLER IN DIAMETER NECESSITATING TIGHTER ALIGNMENT AND STABILITY REQUIREMENTS. A ROTARY JOINT FOR 50 MICRON CORE MULTIMODE FIB ...

A SIMPLE SAFETY ARMING SWITCH FOR GUIDED MISSILES CAN BE BUILT AROUND AN ACCELEROMETER AND INTEGRATING CIRCUIT. IN GENERAL, DURING THE LAUNCH BOOST PHASE, THE ACCELERATION OF A MISSILE INCREASES TO A MAXIMUM JUST BEFORE BURNOUT. CHARACTERISTIC ACCELERATION PROFILES FOR A PARTICULAR MISSILE ARE DEPENDENT UPON FUEL TAILORING AND MISSION REQUIREMENTS; I.E. AIR-TO-AIR MISSION, GROUND-TO-AIR MISSION, E ...
