  • To reduce the forcing response of rotor blades due to the wake of front stator vane, a study of front stator aerodynamic mistuned was proposed. The main aims of this article lie on following two aspects. First one explored how to simulate three-dimension rotor-stator unsteady flow field for asymmetry stator in a simplification algorithm so as to reduce calculating time and computer requirements. The other one is to analyze the force of rotor blade under the asymmetry stator wake using the simplified method. Study shows that asymmetry stator mistuned design changes the original force of rotor from single frequency and higher amplitude to more frequencies and lower amplitude, as a result, mistuned design reduces the wake force on rotor efficiently.
