Not Available Tanner Research proposes an innovative approach for detecting cruise missiles. Instead of using the shape, size, or direction of motion, we propose to use only the speed of the missiles to detect them. Speed of a particular type of missile is a better known factor compared to its outward physical characteristics. Our approach will be based on the ongoing work at Tanner Research on ...

Applied Thin Films, Inc. proposes to use and an innovative aluminum phosphate solution based coating material to act as a sacrificial barrier layer to protect zirconia thermal barrier coatings from molten CMAS ingress and attack. The proposed coating material, known as Cerablak™, will ideally prevent any decrease in zirconia TBC lifetime expectancy and insulation efficiency due to CMAS infiltra ...

Extending gun barrel life has been a long-standing goal for the US Air Force and other DoD agencies. Currently-used chrome plated barrels are susceptible to erosion and corrosion which affects the accuracy of fired bullets due to material loss along the inner surface. The primary cause of barrel degradation is the poor quality chrome coating and attack of steel inner surface by hot gases and comb ...

The rapid increase in the use of the Internet in many aspects of our lives has led to an explosive growth in the spread of malware such as computer worms, viruses, and trojans. Security tools typically examine software for the presence of malware either by looking for specific byte signatures, or (more recently) by analyzing the candidate binary’s internal logic. However, it is surprisingly easy ...

Not Available A new approach to significantly increasing the level of monolithic integration of InP based photonic integrated circuits for RF applications is the subject of this proposed Phase I program. The method is based on a vertically coupled twin wave guide design that has already been successfully used to fabricate lasers and amplifiers. The fabrication process requires no epitaxial re-g ...

We propose to examine the necessary ingredients for the development of marketable codes which will: model the morphology of heterogeneous propellants (a packing code); calculate the thermal and mechancial properties of such a morphology or pack; simulate the combustion of the pack; predict the statistics of aluminum agglomeration on the burning pack surface; simulate the flight of these agglomera ...
