Keywords: aviation engine; blades; failure modes;failure reasons
Abstract:Based on the failure analysis of Failure Analysis Center of Aviation Industry of China in recent years, the materials selection process in the blades of the aviation engine is illustrated, the common failure modes and causes of the failure blades of the aviation engine are discussed, we found that the 90% of the common failure mode in gas turbine blades and compressor blades is fatigue and these variations may be directly linked to the mechanism of failure.
The first few rows of compressor blades of a certain type of the aviation engine have been broken six times science 1990.
Analysis of the materials selection and the basic features Blades from aviation engins are subjected to some common failure modes, such as Mechanical damage, High temperature damage, High temperature exposure, Creep failures, Fatigue failures, Corrosion failures and so on.
Materials defects are also the important causes of the failure blades.
