| 摘 要： | 本文将数值优化方法同计算流体动力学（ＣＦＤ）相结合，形成两种跨声速翼型的气动设计方法，即：最优化方法和反设计方法。采用求解Ｅｕｌｅｒ方程的有限体积法计算流场，通过结合优化算法，从正反两个方向对跨声速翼型进行气动优化设计。实例证明它们是翼型气动设计的有效方法，有较高的工程应用价值。

| Abstract: | By coupling a reliable flow analysis code with constrained numerical optimization algorithms,two aerodynamic design tolls for the aerodynamic design of airfoils are presented in this paper, an optimum method and an inverse method.The flow analysis code is based on the Euler equation in order to simulate aerodynamic characleristics of the transonic flows.The numerical optimization process searches for the best feasible design for the specified design objective and design constraints.Results of several examples at the transonic flow conditions indicate that these two aerodynamic design methods are attractive for engineering applications. |
