摘要：
Based on the computational fluid dynamics, a high-efficiency aerodynamic optimum design system of blade was constructed by using discrete viscous adjoint equation method and combining radial basis function mesh deformation technology. This optimum design system was applied to optimize the profile of an transonic rotor Rotor37.The results show that the shock wave intensity and flow loss decrease in the flow passage, and the total pressure ratio increases by 0.352%, the adiabatic efficiency by 0.339%, and the mass flow by 0.362% under the condition of near peak adiabatic efficiency. Compared with the traditional blade optimum design method, the proposed optimization system can analyse the relationship between blade shape and the cost function explicitly, and reduce the time of optimized design effectively. © 2016, Central South University of Technology.
