摘要：
A self-adaptive center-mutation differential evolution (SCDE) was developed for the high-dimension complex optimization problems, and applied to the high fidelity aerodynamic optimization design of the multi-stage oxidizer turbine blade shapes for cryogenic rocket engines. Performances of design candidates were evaluated by the turbine efficiency based on three-dimensional airfoil geometry design and single-channel flow analysis using commercially available CAD (computer aided design) and CFD (computational fluid dynamics) packages. The reasonable solution is finally achieved, namely, turbine efficiency of the optimal design is 5.25% higher than that of the original one.
