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 ...

A NEW APPROACH TO PHASED ARRAY ANTENNA DESIGN IS PROPOSED, BASED ON UNPUBLISHED WORK AT EMA, WHICH PREDICTS THE POSSIBILITY OF PRODUCING GIGAWATTS OF EFFECTIVE RADIATED POWER.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 ...

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 ...

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 ...

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 ...

THE INTENT OF DOD INSTRUCTION 4245.4, "ACQUISITION OF NUCLEAR SURVIVAL SYSTEMS" IS TO PROVIDE FOR NUCLEAR SURVIVABILITY THROUGHOUT THE LIFE CYCLE OF WEAPON SYSTEMS WHICH ARE REQUIRED TO SURVIVE THE EFFECTS OF NUCLEAR WEAPONS. ONE KEY TO IMPLEMENTING THIS INTENT IS TO INSURE THAT ALL THE PEOPLE INVOLVED ARE FAMILIAR WITH THEIR RESPONSIBILITIES TO IMPLEMENT AND PRESERVE THIS SURVIVABILITY. THIS STUD ...

THE DEVELOPMENT OF COMPACT, HIGH ENERGY DENSITY, HIGH POWER (AND POTENTIALLY C.W.) LASER SYSTEMS CAPABLE OF PROPAGATING THROUGH BOTH AIR AND WATER COULD PAVE THE WAY FOR NEXT GENERATION TACTICAL NAVAL SYSTEMS. APPLICATIONS IN OTHER DEFENSE AREAS AS WELL AS A HOST OF COMMERCIAL APPLICATIONS ARE ALSO POSSIBLE WITH THESE TYPES OF SYSTEMS. WE PROPOSE TO PROVIDE A DETAILED PLAN AND DESIGN OF SPECIFIC E ...

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 ...

CURRENT NUMERICAL COMPUTATIONS TO DESCRIBE NUCLEAR GROUND SHOCK ENVIRONMENTS, NUCLEAR CRATER FORMATION, IMPACT DYNAMICS AND PENETRATION MECHANISMS PRESENTLY EMPLOY EULERIAN-BASED FINITE DIFFERENCE CODES BECAUSE OF THEIR ABILITY TO MODEL THE MASS FLUX PHENOMENA IN TRACKING MATERIAL MOVEMENT THROUGH THE DISCRETIZED SPACE. THE FINITE DIFFERENCE CODES SUFFER IN COMPARISON TO FINITE ELEMENT CODES, HOWE ...
