【Abstract】 This paper introduces the material of turbines’ blades, the constitution of a wing section as well as the destructed form of a blade, and then analyzes the destructed reasons of a blade, and also, finds some ways to overcome the problems. It is found that the main reasons of a blade’s damage are the linkage of a blade’s edge and flutter’s vibration with the elastic blade’s distortion.更多还原
