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 martensitic stainless steel compressor discs of an aero engine. The safe inspection intervals (SIIs) for the compressor discs are calculated using probablistic fracture mechanics (PFM) principles.
