Inspection of Compressor Discs by Ultrasonic Leaky Waves Using an Automated C-Scan System
Damage tolerance concepts are currently being investigated for life extension of critical components of military aircraft engines. The successful implementation of the damage tolerance approach is dependent upon the availability and cost effectiveness of nondestructive inspection (NDI) techniques capable of detecting and sizing small cracks with a high degree of reliability. The reliability of NDI techniques can be determined by using a demonstration program in which a statistically valid number of flawed and flaw free parts are inspected by NDI procedures that duplicate proposed maintenance inspections.
