Abstract:Aiming at the failure of Saw tooth shaped shroud dislocation caused by the operation of low pressure turbine working blade,
based on a comprehensive analysis of the causes of each dislocation fault, the dislocation pattern of the saw tooth of pressure turbine
working blade was summarized, and the model chart was drawn. Then blad complete design method was proposed to prevent the Saw tooth
shaped shroud dislocation of the low pressure turbine. The application results on two different type engine show that this methods is feasible. |
