The objective of this project is to develop and validate an improved technology base for the cold-working of high strength aluminum alloys. The improved technology base consists of the following three legs: 1. A test-validated CAD/CAM tool for performing virtual cold-working and for virtual fatigue testing. 2. An improved design mandrel to achieve the full life improvement potential of cold-w ...

The air force is phasing out the F-15 a very successful fighter jet but in a constant pursuit of air supremacy the air force has invested in a new fighter that will take its place. The f-22 will replace the F-15, it has been designed to have more stealth capabilities and be quicker and more agile than its predecessor.

Oklahoma City Air Logistics Center (OC-ALC) is one of the major service depots responsible for maintaining U.S. Air Force weapon systems, including the B-1B Lancer, the B-52 Stratofortress, the KC-135 Stratotanker, and the E-3 Sentry. Many of these planes have been in service for a great number of years, and thus suffer from fatigue and wear. A great deal of effort is put into inspecting these air ...

Organic film polymers have been the dielectric of choice for high voltage, microsecond-discharge, high energy density capacitors. Electron traps normally found in these films limits their maximun voltage breakdown strength, engergy density, and dissipation. The objective of this proposal is to demonstrate the feasibility of producing higher performance polymer-like dielectric materials without ca ...

We have selected three technologies for the unobtrusive monitoring of bio-behavioral events. Camera-based measures of gaze, including eye and head movements, pupil diameter, vergence, and blink parameters; Laser Doppler Vibrometry (LDV) based measures of cardiovascular and muscle activity; and behavioral measures including movements of body parts as well as keyboard operations will be utilized. Ou ...

We have selected three technologies for the remote monitoring of bio-behavioral events. Camera based measures of gaze, including eye and head movements, pupil diameter, vergence, and blink parameters; Laser Doppler Vibrometry (LDV) based measures of cardiovascular and muscle activity; and behavioral measures including movements of body parts as well as keyboard operations will be utilized. Our co ...

When completed, the work outlined in this Phase II proposal will provide a cylinder kit model that can be utilized to: (1) predict wear rates for a range of currently utilized ring/liner material tribological couples; (2) consider the effect of third-body abrasives on wear rate (including abrasives from deposits formed on piston lands as well as soot from the lubricating oil); (3) predict residen ...

Phase II work focuses on developing an improved high-temperature engine lubricant base stock which will have acceptable vaporization rate and deposits at 875 deg F top ring/liner temperature. Actual lubricating film between the ring face and cylinder liner will be produced by use of a dry-film lubricant additive to the base stock. (Other forms of delivery of dry-film lubricant will be evaluated ...

The goal of this proposal is the production of a designer engineered tissue construct (ETC), a surrogate lung patch-like structure, which will be used to assess the damage induced by thermobaric (TBX) weapons. The information garnered from surrogate-lung-patch tests will be used to help devise effective countermeasures against TBX weapons as well as to reduce the need for costly and often controv ...

The CAMS/GO-81 databases contain massive amounts of historical maintenance data that is unusable in the present form. The primary barrier to effectively using this data for troubleshooting purposes is the "free form" nature of the text fields that describe discrepancies and corrective actions. These text fields contain a wide array of "noisy" data and artifacts that prevent the effective query and ...
