Abstract
The paper reports the results of a demonstration programme carried out to determine the influence of the sensitivity and reliability of nondestructive inspection (NDI) techniques on the damage tolerance based life assessment of aero engine compressor discs. The programme was carried out on AM-355 compressor discs of an aeroengine. The safe inspection intervals (SIIs) for the disc are calculated using deterministic fracture mechanics (DFM) principles and different initial crack length (a sub i) selection criteria.
