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 ...

This proposal offers the demonstration of an approach to integrate the latest corrosion sensor technology with corrosion structural effects modeling to enable the transition from periodic corrosion inspections to an efficient, focused prognostics and health monitoring (PHM) system. The fundamental vision of the proposed program is to provide the customer with a demonstrated process suitable for in ...

Precision weapons using Ladar seekers with automatic target recognition (ATR) will be challenged by an enemy’s efforts to hide, and it will be necessary for these Ladar systems to have enhanced target detection capability. The design features that show the most potential for providing enhanced “hidden” target detection include: multi-pulse detection logic and the use of polarized multi-spect ...

The objective of this work is to develop ATR algorithms that use the spectropolarimetric information in multi-discriminant ladar images to segment, detect and identify hidden targets. Hidden targets using camouflage, concealment and deception are difficult to detect with standard weapons sensors including basic ladar systems. A multi-discriminant ladar having polarized, multi-spectral, and multi ...

The technology resulting from this effort will provide a theoretical wear model which, although focused on predicting slipper surface wear associated with Air Force high-speed sleds, can be utilized with appropriate input modifications to predict wear in a range of mechanical devices where high-pressure and high-velocity surfaces are utilized. In addition, a high-speed, high-pressure pin-on-disk ...

Cognitive Concepts (CC) and High Performance Technologies, Inc. (HPTi) will support the Air Force in defining objective measures of software trustworthiness, not just for embedded systems, but for a broad range of applications. The innovation is to establish measures of the inherent risks in software systems and to provide tools to implement those measures. The measurements we define will be fun ...

We are proposing an approach to the use of CFD that will include the determination of large scale unsteadiness in the flow over the weapons bay. The effects of release of the weapon, the unsteady aerodynamic forces on a given weapon as it leaves the bay and its continued descent will be determined. Metrics for both the large scale unsteadiness associated with flow over the bay, as well as metric ...

A system that provides a large field of regard for propagation of a laser beam from a transonic platform will be evaluated at larger scale and in greater detail (with more realistic and detailed geometry) than the successful Phase I demonstrations. Critical and practical issues identified in phase I will be addressed during the Phase II effort. The design includes a concept to address the fact t ...
