In this paper, the genetic algorithm is applied to the optimization design of turbine mechanical cascade, and the optimal design model is established with minimizing the mean square deviation of the actual pressure and the ideal pressure of the blade back arc as the objective function. The optimization example shows that the application of this algorithm will improve the flow field inside the cascade and improve the aerodynamic performance of the cascade.
