Study for the Design of an Eddy Current Array Probe for the Imaging of Aeronautical Fastener Holes

Résumé

The design of an eddy current imaging array probe dedicated to the inspection of aeronautical fastener holes is presented. The probe aims at enhancing the characterisation of defects such as surface fatigue cracks as well as at simplifying the inspection procedures (limited probe displacements). In this paper, a general probe design featuring separate inducing and sensing functions is proposed and studied thanks to 3D finite element computations. Then, a first experimental validation of the structure is given. Finally alternative pickup sensor technologies are considered. A quantitative study of the influence of both the nature of the used sensors and their arrangement as part of a multisensor array is proposed and discussed.
