Abstract

This paper describes the development programme for a portable non-contact inspection system, suitable for in-service inspection of aeronautical structures. The instrument is powered from a re-chargeable battery pack which provides over six hours of continuous usage. The transducer front end is a lightweight, hand-held assembly in which a pair of piezocomposite transducers are housed. Angular adjustment of the transducers enables the instrument to operate into a variety of materials, with metallic and composite materials of primary interest. Importantly, a single channel oscilloscope has, been incorporated to provide visual interpretation of the processed received signal. Defect detection is demonstrated in a number of aerospace samples, with the resultant C-scans presented where appropriate.
