AGARD/SMP Review Damage Tolerance for Engine Structures. 1. Non-Destructive Evaluation

Abstract

Most current military and all civil engines are operated under 'Safe- life' procedures for their critical components. Experience has shown that this philosophy presents two drawbacks: (a) The move towards designs allowing higher operational stresses, and the use of advanced high-strength alloys make it likely that a disc burst could happen (following a rapid crack growth) well before the statistically-based 'Safe-life' has been achieved. (b) It is potentially wasteful of expensive components, since it has been estimated that over 80% of engine discs have ten or more low cycle fatigue lives remaining when discarded under Safe-life rules. Damage Tolerance being an alternative lifeing philosophy, the Sub-Committee on Damage Tolerance Concepts for the Design of Engine Constituents has therefore decided to conduct a series of four Workshops addressing the areas critical to Damage Tolerant design of engine parts. The present report includes the papers presented during Workshop 1 which was devoted to Non-Destructive Evaluation of Components. France.
