Abstract
The work describes the use of acoustic emission to detect fatigue cracks in a full-scale aircraft structure during ground durability and damage tolerance testing. Data is presented for about 3,000 equivalent flying hours of continuous monitoring. Attention is focussed on the relative effectiveness of periodic acoustic emission testing and continuous acoustic emission monitoring. Comparison of these results to those of conventional NDI are made.
