Progressive Fatigue Testing Methods of Aircraft Turbine Engine Blade Materials

Safety is the most important value in aviation.However, an aircraft incident may occur.Sometimes, during operation or maintenance, new, previously unknown degradation effects can be observed and need to be tested or analysed in the shortest possible time.This article describes the advanced laboratory mechanical testing of turbine blades, combined with a data classification process, offering a way to find the root cause of some specific fatigue damage and thus contribute to increased operational safety.
