摘　　要：近似模型方法在工程优化设计中开始得到重视。本文分别应用Kriging方法和响应面方法进行了翼型气动优化设计。结果表明,Kriging方法的设计结果,升阻比较参考翼型提高了81%;在初始设计空间,响应面方法的结果很差,通过不断缩减设计空间,设计得到了有效的改善,升阻比提高了70%,但需要的计算量远远高于Kriging模型。The approximate model has been used in engineering optimization design widely. In this paper, the Kriging method and the response surface method are both adopted in the aerodynamic optimization design of airfoil. The results show that the lift-drag ratio of Kriging design increases 81 percents comparing with the referenced airfoil; while the result of the response surface method is very poor in the original design space. This status is amended effectively through reducing the design space continuously and the lift-drag ratio increases by 70%, however the calculation cost is far more expensive than the Kriging method.
