摘　　要：为了确保翼型性能,需要采用恰当的翼型参数化方法生成所需要的翼型几何体。利用CST方法生成具有代表性的Clark-Y二维机翼,同时对CST方法生成三维几何体进行了详细研究。在原有的CST方法基础上对生成三维机翼的方法进行改进,用来解决机翼外形不连续变化的情况,生成可控分段变化三维机翼外形,控制效果良好。the CST algorithm is used to generate a Clark-Y two-dimensional airfoil representative, and the CST algorithm to generate 3D geometry is studied. A method of using piecewise defined description of airfoil based on the original CST method is proposed, which is used to solve the wing shape not continuous changing, finally the three-dimensional controllable wing model is got and has good effect.
