Abstract

ABSTRACT: The goal of this SBIR program is to meet the Air Force"s need for a low-cost, bolt-hole inspection technology for aircraft structures that employ nut plates. Specifically, the inspection entails the detection of cracks on the edge of the hole next to the nut plate. The system would be small, light-weight, easy to use, and significantly outperform currently available techniques. In Phase I of the program JENTEK demonstrated the feasibility of the MWM Array technology to meet the Air Force"s target detection requirement using EDM notched specimens. In Phase II JENTEK will work with the Air Force to select a specific bolt-hole application and draft a Master Requirements Document for the implementation of the proposed inspection using JENTEK"s MWM Array technology and commercial GridStation HandHeld System. Implementation will require adaptation of a prototype bolt-hole scanner, mandrels, and sensors for the target application. After testing the integrated system, a preliminary POD study will be performed per the guidelines provided in MIL HDBK-1823A to determine the detection capability. A transition plan with cost-benefit analysis will be provided to the Air Force for implementation of the system. Finally, the system capability will be demonstrated on components at an Air Force facility. BENEFIT: If this program is successful, JENTEK will deliver to the Air Force an inspection system for bolt holes with attached nut plates capable of detecting edge cracks that are smaller than those detectable using conventional inspection techniques. The system will use a prototype bolt-hole scanning fixture, mandrels and sensors adapted for the targeted application and JENTEK"s commercial GridStation HandHeld instrument. With the ability to detect significantly smaller cracks, the Air Force will be able to utilize more proactive maintenance techniques and significantly lengthen the useful life of the inspected components.
