A quality simulation which allows a user to simulate the acoustic emissions in a multi-source environment and then study the effects these conditions have on a set of acoustic sensors would be of great value. As acoustic sensors technology continues to advance with robust algorithms for detection, tracking and identification as well as high performance hardware providing real-time operation, thes ...

THIS PROJECT ADDRESSES SYSTEMS TO REDUCE NOISE AND VIBRATIONS EMANATING FROM AUXILIAIY POWER UNITS (APUS) WHICH ARE BEING INITEGRATED INTO ARMY VEHICLES AND SHELTERS. EXCESSIVE NOISE AND VIBRATIONS ARE HARMFUL TO AND HINDER THE EFFECTIVENESS OF OPERATORS AND OCCUPANTS. IN MILITARY EQUIPMENT, IT IS ALSO BENEFICIAL TO AVOID EMANATIONS THAT MIGHT BE USED AS DETECTION SIGNATURES . THIS EXPLORATORY DEV ...

This project applies a combination of Artificial Neural Networks (ANN), Genetic Algorithms (GA), and CAD software to the problem of optimum armor design. Previous work for TACOM has established the efficacy of ANN/GA as applied to the problem of 1-D armor design. This new work will extend the concept to full 3-D vehicle geometries (CAD models). The CAD part of the code will handle the 3D data d ...

IN A FEW YEARS, THE NATIONAL TRAINING CENTER (NTC) WILL HAVE NEW SIMULATION SYSTEMS AND UPGRADES TO RDMA AND RMCS. GIVEN EFFECTIVE AND EFFICIENT INTEGRATION, TEHSE SYSTEMS WILL INCREASE, SIGNIFICANTLY, THE AMOUNT AND FIDELITY OF DATA AVAILABLE TO THE TRAINING SNALYST. HOW EFFECTIVE THESE IMPROVEMENTS ARE DEPENDS ON HOW EFFICIENTLY THE MAN-MACHINE COMBINAITONS AT TRAINING ANALYST WORK STATIONS ARE ...

N/A

RAPID INITIATED PROPAGATION (RIP) IGNITORS PROVIDE MORE UNIFORM FLAME SPREADING THROUGH PROPELLANT BEDS THROUGH CYLINDRICAL WAVE EXPANSION ACCOMPANIED BY REDUCED EXPANSION EFFECTS ON THE PRESSURE PULSE. IMPROVEMENTS IN RIP IGNITOR PERFORMANCE ARE POSSIBLE THROUGH: INCREASES IN PRIMER CHARGE DENSITY, REDUCTION IN IGNITOR FREE VOLUME, BLENDS OF IGNITOR MATERIALS, AND USE OF HIGH EMISSIVITY SOLIDS. T ...

CURRENT MOISTURE BARRIERS FOR AMMUNITION CONTAINERS CONSIST OF LAYERS OF ASPHALT IMPREGNATED PAPER AND ALUMINUM FOIL. ALUMINUM FOIL IS NOTED FOR ITS PINHOLE LEAKS. MOISTURE WILL DIFFUSE THROUGH ASPHALT IMPREGNATED PAPER. CONSEQUENTLY, MOISTURE-INDUCED CORROSION OF AMMUNITION AND DEGRADATION OF FUZE AND PROPELLANT CAN FREQUENTLY OCCUR OVER LONG TIME PERIODS. A NOVEL SOL-GEL-DERIVED 47 WT% ALUMINOSI ...

A HIGH CELL DENSITY FERMENTATION TECHNOLOGY IS PROPOSED FOR THE PRODUCTION OF MICROBIAL NERVE GAS DEGRADING ENZYMES. THIS TECHNOLOGY WILL RELY ON THE DEVELOPMENT OF AN ULTRA HIGH CELL DENSITY (GREATER THAN 100 G DRY WEIGHT CELLS/L) CONTINUOUS FERMENTATION FOR THE PRODUCTION OF MICROBIAL ENZYMES KNOWN TO DEGRADE NERVE GASES.
