摘　　要：将N-S方程流场分析程序和SQP（序列二次规划）结合起来，发展了一种工程实用的跨音速翼型优化设计方法，用以提高翼型在多个设计点、多种约束条件下的气动性能。由N-S方程计算得到的升力、阻力等气动参数构成目标函数，用数值优化程序对其进行最优化。超临界翼型的设计实例表明，该方法设计质量高，所需机时少，易于实施，有较大的工程应用价值。This paper presents a transonic airfoil design procedure that couples viscous flow analysis and numerical optimization to search an airfoil geometry with improved aerodynamic performance characteristics at multiple design points while satisfying specified design constraints. The flow was modeled with Reynolds-averaged Navier-Stokes equations in order to produce reliable designs. The multipoint optimization algorithm was based on SQP（Successive Quadratic Programming） method which drove the design process efficiently and robustly. Example result is shown for transonic supercritical airfoil design. The study indicates that the proposed approach is attractive for practical use because of its high design quality and reasonable computational cost.
