"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 ...

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 ...

"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 ...

The Virtual Engineering firm is a reality, with a team of scientists and engineers scattered at home sites working together to solve tough engineering problems. This SBIR will perform research and development to provide collaborative system engineering tools for network engineering projects. We will explore new directions for collaborative systems engineering (SE) that enable distributed req ...

"Our Phase I SBIR project performed innovative research to addressthis problem. This research investigated the feasibility ofdeveloping a multi-purpose, crash survivable, universal flightinformation system and data recorder (UFDR). The UFDR willdigitally process and record structural, engine/propulsion,electrical/avionics, environmental, exceedance, and event data tocrash survivable memory with c ...

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 ...

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 ...

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 ...

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 ...
