Recent efforts in the target vulnerability community (fixed ground targets, mobile ground targets, and aircraft) have focused on enhancing the blast and fragmentation modeling from weapon detonations. This includes modeling propagation of the detonation effects from the weapon through their interaction with the target geometry, to the development of loads on and response of the target structure. ...

The objective of this work is to develop analytical techniques to characterize wear and gouging phenomena of slippers at speeds up to hypersonic and demonstrate means to evaluate or reduce slipper wear/gouging. Specifically, we will develop analytical techniques that can be used to predict slipper wear patterns and gouging phenomena throughout the sled velocity regime to Mach 10. This will inclu ...

Beam Technology Corporation is prepared to develop an innovative personal Radio frequency Radiation Dosimeter based on concepts originally enunciated by Dr. Johnathan Kiel, The approach will use a technology that promises to be much more versatile than currently available methods of measurement, which often employ E-field probes and meters. The objective is to use a novel chemical, Diazoluminomel ...

The CFTF Centrifuge at Armstrong Laboratory will be a useful tool for crewmember training and human factors research for future high performance aircraft. The centrifuge features an accelearation of performance that is unmatched by other Air Force facilities, however, it lacks a set of powered gimbals that would allow positioning of the rider with respect to acceleration. With these additional d ...

The goal of this research is to synthesize a new type of fluorinated polymer resins to be used for aircraft coatings. Reactive difunctional monomers containing relatively long perfluoroalkyl branches will be synthesized by direct fluorination. We hope to demonstrate that the new resins containing relatively long perfluoroalkyl branches provide the ultimate protection against severe weather cond ...

Bends in waveguides are a problem for high-voltage Ultra-Wideband (UWB) systems. The difficulty arises because only a straight section of standard transmission line can support a pure TEM mode. And a pure TEM mode is necessary to preserve the risetime of the transmitted impulse. When there is a bend in the waveguide, the transmitted signal is a broader impulse than the incident signal. This ca ...

The opportunity exists to apply evolving technology for nonlinear adaptive control to autopilot design for precision guided munitions. The approach employs artificial neural networks to represent errors made in inverting the nonlinearities in a feedback inverting controller. Using an on-line method for weight adaptation results in a highly effective local approximator to the inversion error. Re ...

The production of semi-conductor wafers is a multibillion dollar industry. The 1996 worldwide semiconductor market is estimated at $162 billion with a growth potential to $309 billion by the year 2000. Thus, even a small improvement in control during the manufacturing process could have a large impact on the economic viability of many companies and products. A critical factor in all semiconduct ...

This project will identify and characterize the principles governing operations in the sustainment domain for end items undergoing maintenance and repair with minimal disassembly, define requirements for sustainment-oriented planning and scheduling systems, and produce a candiddate implementation architecture for an integrated, situation-based planning, scheduling, and dispatch support system. Th ...
