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 ...

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 ...

Thermal control of spacecraft is accomplished through the optical and thermal properties of the eternal surfaces of the vehicle. The use of thermal control coatings or second surface mirrors on these surfaces ar common methods for managing the overall thermal environment of spacecraft. The proposed low solar absorbance ( ) high emittance ( ET ) thermal control (TC) coating(s) shall be developed ...

High performance military aircraft operating in the hypersonic regime produce large heat loads that can only be managed with endothermic fuels. However, the current knowledge of endothermic chemistry in fuels and its effects over a range of aircraft flight conditions is extremely limited. The proposed Phase I study is aimed at the development of advanced finite rate models to characterize dehydr ...

Focal plane arrays (FPAs) are one of the most critical and expensive components in infrared imaging equipment, such as nigh vision, security and surveillance systems. In the device manufacturing processes, at present, it is not possible to determine if the final product is successful until all steps and materials have been incorporated. Since this entire manufacturing process can take up to 12 w ...

The need for small portable, low-cost instruments for field environmental measurements is well documented. Nomadics is developing powerful handheld instruments based on the portable computers and PCMCIA cards. We intent to marry existing proven (but not yet deployed) sensor technologies with portable computers (such as laptops, palmtops and PDAs) using the industry standard PCMCIA card and virtu ...

Computing and communications requirements to support modern C4I systems have undergone considerable expansion in the last decade. Requirements for C4I interoperability between the services, along with recent developments in C4I doctrine (such as C4I for the Warrior) will require far more sophisticated, more complex, and more heterogeneous computing and communications technology. Effective design a ...
