This research will determine extent and nature of the neutralization of bacterial spores when they are exposed, for very short times to high temperatures, pressures, and chemicals important in Agent Defeat weapons.. An exposure system will be constructedcapable of providing the ultra-short exposure times (on the order of ms) that are characteristic of bomb explosions and will be capable of exposi ...

High resolution modeling of the aerosolization process for relatively large liquid jets is needed to quantify the dispersion of hazardous chemical or biological agents from damaged/punctured containers. A second application is the prediction of thedistribution of neutralization agents injected into clouds of hazardous chemical or biological agents. A high fidelity model is needed to provide accura ...

A simulation tool is proposed to model and simulate the wind fields, turbulence fields, and the unsteady dispersion of NCBR substances in urban areas on the building to city blocks scale. This Computational Fluid Dynamics (CFD)-based approach has beenshown to accurately simulate the urban wind and turbulence fields with minimal approximations, and has been demonstrated by modeling the flow fields ...

Military aircraft are largely constructed from special aluminum alloys, which typically have secondary precipitate phases that substantially improve mechanical strength. However, these regions also promote corrosion in such common environmental conditionsas acid rain, saltwater, and thermal cycling. The problem is significant enough that the U.S. Air Force expends approximately $1 billion per year ...

Reducing the cost of launching payloads into low earth orbit by a factor of 10 or 100 requires revolutionary changes in launching architectures. The Laser Lightcraft holds the potential for such savings by placing the bulk of the propulsion system on theground by using a ground-based laser to provide the impulse for lifting the payload. Attitude control for the Lightcraft is critical. This Phas ...
