ABSTRACT: Accurate measurement of fastener profile relative to the aircraft skin is critical to ensure that aircraft meet operation specifications and to identify areas that require rework to meet tight manufacturing tolerances. Current measurement methods rely on mechanical dial indicators that struggle to provide the required accuracy, are difficult to use in tight areas, and demand a high degree of operator skill. The goal of this project is development of an automated, hand-held tool for measurement of fastener profile that is fast, easy to use, and highly accurate. Our approach relies on proven noncontact inspection technology that has been shown to provide extremely high accuracy. BENEFIT: The technology developed on this project will provide a new methodology for high speed, easy to use measurement of fastener profile in aircraft assemblies.
