摘　　要：选择适合低风速的NACA63系列翼型,通过一定的成型方法,构造出完全对称的S型叶片。以三维雷诺平均Navier-Stokes方程为基础,应用正交优化方法,对S型叶片的叶型安装角沿径向的分布规律进行了正交优化设计。在满足风量、风压要求及叶片数较少、弦长较小的前提下,获得了最高的流动效率,取得了良好的设计效果。NACA63 series airfoil,which is suitable for low speed,is selected to build symmetrical S type blade through the specific molding method.The method of orthogonal optimal design is implemented for the distribution rules with radial direction of installation angle of S type blade based on 3-D Reynolds-Averaged Navier-Stokes equations.Under the condition of meeting the requirements of flow and pressure of wind and less blades and shorter chords,the highest flow efficiency is obtained and the good design effect is achieved.
