摘要
优化设计方法由机翼外形和计算网格生成方法、跨音速机翼全位势方程数值解法和数值优化算法等方法组成。采用独特的机翼外形曲线拟合函数摄动方法来改变机翼。数值实验表明，只须在半翼展中部剖面上选择两个结点处的翼面坐标进行摄动，即可获得气动上满意的优化解答，并可节省大量机时。
The method consists of wing geometry and grid generation,transonic full potential solver and numerical optimization algorithm,etc. An especial perturbation technique of curve fitting shape function is applied for variation of the wing shape. Numerical test indicated that it only needed to perturb the ordinates of two spline support points located at the section of the middle semispan of the wing. An aerodynamically satisfactory optimization solution can be obtained,grealty saving the CPU time.
