The proposed approach for Phase I of this effort brings together two key items that are needed to work in concert with one another: advanced fatigue assessment methods and non-destructive inspection & detection techniques. Successful synthesis of these elements and the engineering disciplines behind them will provide an optimized and advanced method of taking full advantage of engineered residual ...

The USAF recognizes that benefits to cold working fastener holes include significantly increased life of a structure subjected to fatigue loading. However, full realization of this potential from a maintenance and engineering standpoint is hindered by the fact that there is currently no adequate field technique for determining how well the material structure immediately surrounding the hole has re ...

The Phase I objective is a conceptual design of a hyperspectral/multimodal fundus camera for assessing laser damage.  The premise to be ultimately proven in this project is that damage to the fundus, from laser irradiation, may be characterized and detected by reflectance spectra, and by measuring function such as flow and perfusion.  The system will incorporate an existing fundus camera model ( ...

Electrically Solid Propellants (ESP) are a new class of energetic material that can be formulated as a pyrogen having several safety advantages over BKNO3. These ESP are inherently safe from accidental ignition being controllable via electrical power input. When an ESP is fitted with electrodes and a current of the required voltage is applied, it ignites and continues to energetically burn until ...

The Unexploded Ordnance Asset RFID System (UARS) is an active low frequency RFID tracking system designed for locating unexploded ordinance (UXO) on the battlefield.  The system is a passive thin collar RFID tag that is placed onto the munition during manufacture and becomes activated after delivery on target.  Once activated, the RFID tag enters a passive listening mode, waiting for a specific ...

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 ...

This proposal will develop new filter and guidance algorithms and demonstrate their effectiveness in a 6 degrees-of-freedom missile-target simulator. The new algorithms for the filters will be based on a)optimal estimation b)sliding mode c) neural networks and d)partcle filters. The guidance algorithms will be based on a)optimal guidance and b)sliding mode. Preliminary promising results on chosen ...

The objective of the proposed research and development work is to create new types of compact, autonomous explosive-driven high-power microwave (HPM) systems based on the magnetic flux compression generator (FCG). There will be no moving parts (to include armatures) in these devices; the systems will be completely solid-state units. They will include all components necessary for operation: a comp ...

The major requirements for this program include the modeling of optical switching fabric technologies appropriate to space-borne systems at very high speed. Specifically, this program will evaluate two OptiComp candidate optical transceiver technologies against a Serial Rapid IO switching fabric. A down-selection to one optical transceiver technology will be made. Then, a simulation of that Serial ...

The major requirements for this program include the modeling of optical routing technologies appropriate to space-borne systems at very high speed. This program will investigate optical routing at speeds to from 3.125 ro 10 Gbps per channel, with a wavelength/channel density from 4 to 16 wavelengths. Models will be constructed for these regimes, and an experimental demonstration of an 8-wavelength ...
