Paper Abstract

Shearography is an approved and powerful tool for the nondestructive inspection of industrial components with respect to material faults and technical imperfections. An application field of high interest is the in-service inspection of aircraft components. However, the non-cooperative character of the surface of various aircraft components to be inspected has to be taken into account carefully. This paper describes a complete test facility consisting of a shearographic sensor, adapted loading equipment for thermal and mechanical stressing and a new evaluation software ensuring a high sensitivity for fault detection. Furtheron a survey of the performance of the system is given on example of different aircraft components that shows the advantages of shearography in comparison with other inspection techniques, such as ultrasonics and thermography.
