This program seeks to develop advanced, high-voltage components for the next generation of military fuzes.    Specifically, we propose to develop and test three different high-voltage switch modules that can be implemented into future in-line, high-voltage fuzing and firing set systems.  During the Phase I effort, DSR will research three different high-voltage switches for fuzing applications. ...

We propose a modular, extensible software package for modeling fiber laser arrays. This module will be developed using Mathwork''''s MATLAB and SIMULINK tools. This will ensure compatibility with a wide variety of computer systems. The software will be developed around a graphical user interface that will provide the user with a wide variety of options for modeling any type of fiber laser system. ...

The European Union''s RoHS and WEE Directives mandated the elimination of the carcinogenic, hexavalent chromium coatings for metals, including magnesium and zinc-nickel plated substrates.  The purpose of this project is to find chemistry that will meet requirements of industry performance specifications and of the mandate.  METALAST intends to explore trivalent chromium in conjunction with two o ...

Development of a mechanical de-orbiting system that can be attached to a DoD satellite asset as part of the initial mission planning can provide a means to safely and cost effectively de-orbit a satellite once it has completed its mission or if a de-orbit is required due to a failure of a key system or instrument.  The fact that all satellites will fail over time leads to the need to de-orbit the ...

Innovative Materials Testing Technologies, Inc., (IMTT), supported by Lockheed Martin Company, propose a methodology, based on a combination of two novel technologies, for the in-situ measurement of general and pitting corrosion in aluminum structures to meet the requirements stated in the solicited topic ¡°In-Situ Detection of Hidden General and Pitting Corrosion of Aircraft Structure¡±. The ...

Future military satellite communications systems will have higher signal capacities by employing complex modulation schemes in channels that are closely spaced in frequency (21MHz). Nonlinearities in the terminal electronics, particularly power amplifiers, cause spectral regrowth, where by extraneous power from one channel interferes with signal from adjacent channels. As a result, communication d ...

AFRL has performed basic research in Space Situational Awareness (SSA) for many years.  With the successful execution of multiple programs during the past two years, AFRL has become the de facto center of mass in the SSA development community. To provide a more complete Defensive Counterspace (DCS) system, AFRLs portfolio of SSA capabilities must be extended to provide Resource Management (RM) fu ...

This Small Business Technology Transfer program will develop a spectroscopic polarimeter-on-a-chip using novel plasmonic resonant cavities sensitive to linear polarization over a narrow wavelength range. Spectral selection will be possible through geometric scaling, with this work concentrating on the visible to near infrared wavelength band. Dielectric gratings with subwavelength period will act ...

Having recently built a 32-beam micromachining workstation, a systematic investigation that rigorously quantifies the multifocal, micromachining approach will be performed. While the manufacturing throughput gains of a multifocal approach are obvious, the method needs to be thoroughly characterized to identify the conditions that produce the features of highest integrity at the highest manufacturi ...

Machining cooling holes in turbine fan blades is non-trivial.  Blades and vanes are made from superalloys and coated with thermal barrier coatings (TBC) to survive extreme temperatures after the combustion section of a jet engine.  Classical methods such as EDM or nanosecond laser micromachining have serious drawbacks in the size of hole and the amount of collateral damage to the surrounding mat ...
