| Abstract: | Based on Nastrsan, it establishes the model of the aerospace engines turbine, draws a conclusion. The simulation shows that stress yield is easily occurred in the interchange of turbine, leaf and transition curve area is the danger zone of fatigue damage, illustrates the list about 15 dangerous unit points of fatigue damage. This provides the reference to improve the engine turbine＇s service life. |
