摘要：
In view of the physical problem of unsteady aerodynamic excitation force induced by flow interaction between turbine stage blades，an aerodynamic optimization design method for both turbine guide vanes and rotor blades was proposed and carried out. The research results indicated that not only the time-average aerodynamic force of the turbine rotor blade was reduced by about 8%， but also the aerodynamic excitation characteristics of other phases were improved for rotor blade. The results indicated the feasibility of this aerodynamic optimization design method. Moreover，the optimized guide vane had obvious curved and swept feature， allowing to reduce the unsteady aerodynamic excitation force of downstream rotor blade. This is a new understanding of the flow mechanism of curved blades" in turbine unsteady aerodynamic design technology field，which is very worthy of further research. © 2024 Beijing University of Aeronautics and Astronautics (BUAA).
