Abstract

Purpose of the program is to evaluate acoustic emission (AE) for in-flight detection of fatigue crack growth in aircraft structure. A special AE system was developed and installed on a RAAF Macchi jet trainer. It has been effectively measuring AE from a fatigue crack since August, 1978. Work is continuing to investigate correlation of AE data with crack growth.
