In-Place Dynamic Stress Relief

ABSTRACT: In the following proposal, we present a plan to improve the current state of vibratory stress relief and offer a method that ensures predictability and verifies effectiveness. The proposed technology seeks to remedy the shortcomings of typical VSR systems, specifically by allowing the technology to be used in-situ without dis-assembly of the repaired component. Additionally, the recommended system will be adaptable to various materials, component shapes, and sizes. Ramifications of such a system are considerable, increasing service life and allowing for significant life cycle cost savings on a highly advanced and valued aircraft. BENEFIT: Proposed in-situ stress relief technology will make weld repairs possible on high performance titanium aircraft frames, extending aircraft service lives and thus offering tremendous cost savings for the Air Force and the Government. The technology is immediately applicable to commercial airplanes and may be extended to many industries as a low-cost alternative to the thermal stress relief process.
