【 摘 要 】

Non-destructive detection of defects in countersunk of rivets in multi-layer air-intake structures is essential for ensuring structural integrity and flight safety. This paper presents an eddy current test procedure developed for reliable detection of simulated fatigue cracks and corrosion products in rivets of air-intake structures. This procedure is capable of reliably detecting 0.25 mm deep defects in 4 mm dia rivets and 0.75 mm deep defects in 5 mm dia rivets. Further, it is not influenced by thickness of the multilayers.
