We propose to develop a simulation system that integrates CAD/CAM/CAT tools into a Virtual Manufacturing Environment, and to demonstrate the proof of concept. The proposed system will be based on the demonstrated functionality of Multi-dimensional, user-oriented Synthetic Environment, UuSE (pronounced "muse'). Developed at Sandia National Laboratories by UuSE Technologies, Inc. (principals a ...

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 proposed program is focused specifically on developing and optimizing advanced Prognostics and Health Management (PHM) system designs for various Joint Strike Fighter aircraft systems and subsystems. A PHM design optimization tool developed under aseparate program will be utilized to examine several selected JSF aircraft areas including the propulsion system (Fan/Compressor/Turbine, Engine ...

"Reflex triode bremsstrahlung sources potentially provide warm X-ray sources (20 keV to 500 keV), capable of generating high doses (~10 cal/g gold) over exposure areas of ~20 cm2. This needed capability allows experimental verification of warm X-ray inducedthermomechanical response, SGEMP, and box IEMP models for achieving component and system certification to hostile environments.In a reflex trio ...

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 SHALLOW WATER SONAR SYSTEM WILL BE DESIGNED AND ANALYZED USING A UNIQUE RAY-BASED SHALLOW WATER PROPAGATION AND REVERBERATION MODEL. THE BASELINE CANDIDATE SYSTEM IS A PLANAR ARRAY SONAR IN A VDS CONFIGURATION. THE ARRAY USES LIGHTWEIGHT CYLINDRICAL TRANSMITTING ELEMENTS AND DIFAR RECEIVING ELEMENTS TO ACHIEVE EXCELLENT PERFORMANCE IN A COMPACT CONFIGURATION. ITS SIZE AND WEIGHT ARE APPROPRIATE ...

A NEW APPROACH TO PHASED ARRAY ANTENNA DESIGN IS PROPOSED, BASED ON UNPUBLISHED WORK AT EMA, WHICH PREDICTS THE POSSIBILITY OF PRODUCING GIGAWATTS OF EFFECTIVE RADIATED POWER.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