Abstract :
Aero-engine blades always failure due to impact of foreign object damage in service. Damnification and consequent fracture failure of blade is one of the main failure modes for the compressor blades in aero-engine. Damage characteristic on blades caused by different kind of material are various. Observation on damaged surfaces, trace analysis and surface element analysis by means of SEM and X-ray energy spectrum are effective methods to estimate the attribute, component and outline of foreign object. In this paper, analysis on several cases of FOD are introduced. The features, principles and rules of several typical FOD modes are summarized through failure cases analysis.
