Critical aircraft structures are susceptible to hidden corrosion. Find-it and fix-it approaches are inefficient as it relates to managing the problems associated with corrosion. More comprehensive corrosion information may be obtained using data fusion from several detection and evaluation methods. To this end, microwave, conventional and pulsed eddy current data from a multi-layer corroded panel, representing an aircraft lap joint, are fused and used as inputs to a structural analysis ...
The paper describes the evaluation of several advanced imaging methods for detecting damage hidden under aircraft coating systems. The specific imaging technologies include thermographic imaging, mid-infrared imaging, and terahertz imaging which are all relatively mature and widely known throughout the scientific community.
