Abstract

The theoretical design and experimental evaluation of a prototype through air ultrasonic inspection system are described. It is based around a ceramic-epoxy composite transducer configuration that is tailored specifically for through transmission scanning in air. A simulation model is used for the design of transmission and reception devices and the main factors influencing transduction performance are discussed with respect to the air and test specimen interface. Through transmission results are presented for inspection of solid test samples, including carbon-fiber composites plates, typical of those encountered in the aerospace industry
