摘　　要：把最优化方法与机翼的气动力求解相结合，进行跨音速机翼的气动优化设计。采用最优化方法为遗传算法，机翼的气动力由三维欧拉方程的数值解来提供。与基准机翼相比较，优化设计的机翼其气动性能有较大幅度的提高。In this paper, aerodynamic optimization design of transonic wing is carried out by combination of optimization method with aerodynamic analysis of wing. Genetic algorithm is adopted as optimization method, and aerodynamic forces are provided by the numerical solution of three dimensional Euler equations. Compared with the baseline wing, the optimized wing has much better aerodynamic performance. Comparisons show that genetic algorithm is feasible and effective when it is used in optimization design of wing.
