把基于实数编码的遗传算法与可变容差法相结合,建立了数值优化设计中的混合演化策略(HES),并将其与机翼的气动分析相结合进行跨音速机翼的气动优化设计.与基准机翼相比,优化设计的机翼其气动性能有较大程度的改善,表明了混合演化策略在机翼优化设计中的有效性.与单纯的遗传算法(GA)相比,应用混合演化策略的气动优化设计具有更高的优化效率和优化质量.

Aerodynamic Optimization Design of Wing Using Hybrid Evolutionary Strategy

One of the hybrid evolutionary strategies in numerical optimization and design is established by combination of genetic algorithm based on real number skill with variable error method. Then the strategy, combined with aerodynamic analysis of wing, is used to carry out aerodynamic optimization design of transonic wing. Compared with the baseline, the designed wing has a considerable improvement on aerodynamic performance. It shows that it is effective to design wings using hybrid evolutionary strategy. Compared with genetic algorithm, the designed hybrid evolutionary strategy is capable of dealing with aerodynamic optimization design with higher quality and efficiency.
