"Under Phase I array-processing techniques were developed andanalyzed which provided an effective interference rejectioncapability for acoustic intercept systems. This was demonstratedvia computer analysis and simulation of these techniques asapplied to a volumetric acoustic intercept sensor. It was shownthat, using such an array, an adaptive spatial normalizationtechnique could be used to suppr ...

"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 ...

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 ...

The objective of agile manufacturing is to increase competitiveness of the US manufacturing base, while addressing DoD priorities, with a combined goal of improving US global competitiveness and national security. To achieve this objective, significant changes in technology and infrastructure must occur. This proposal addresses a significant component of these required changes, a Next Generation C ...

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 ...

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 ...

Cured aircraft composite materials present a particularly difficult challenge for recycling technology. Those materials have mostly thermosetting epoxy matrices and occur in intimate association with metals, paints, and coatings. Current techniques for recycling thermoset composites, mostly for automotive sheet molding compounds (SMC), involve pulverizing the material for use as fillers. Th ...

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 ...

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 ...

"Refine the characteristics of, and integrate a softwareimplementation of, an optimal protocol suite for reliable IP WANtransport over GEO satellites. The prototype Application TrafficController (ATC), integrating a caching controller, compressioncontroller, and prioritization and queuing controller, with anautomatic transport selector and enhanced transport protocols,will enable reliable multica ...
