摘　　要：本文对前人提出的各种二维流动压缩性修正方法进行了大量分析、计算和比较,提出了多段翼型复杂混合流场的压缩性修正方法,把翼型绕流划分为外部流场和内部流场(翼段间缝隙)。外部流场采用Nrstrud方法进行修正,内部流场采用Lieblein方法修正,并对这两种修正方法进行了局部改进使其更加应用方便。本文翼型绕流压缩性修正方法的应用,使现有的多段翼型失速特性计算程序有了更为广泛的应用范围。Based on a great deal of analysis arid computation for various correction methods, a compressibility correction for the subsonic multi-element airfoil flow has been put forward. The flow field is divided into the external and the internal flow regions. For the external flow,the Norstrud's method is used,and for the internal flow,Lieblein's method is used. Furthermore,these two corrections are developed to be used more easily. Success of the compressibility correction makes the computer program of the Multi-element airfoil widely used.
