| 摘 要： | 通过低速和高速风洞试验对翼身组合体的前体非对称分离涡气动特性的研究,以及对旋成体非对称涡进行了大量的资料研究,结果表明:本专题所研制的细长翼身组合体的前体在较大迎角下有多个非对称涡;迎角、旋成体的外形,尤其是头部的几何形状是细长前体出现非对称涡的关键因素。

| Abstract: | This paper is about an investigation on asymmetric vortex mechanism, interference and control of slender wing and body.Wind tunnel tests at low speed to high speed and lots of informations investigation on asymmetric vortex characteristic of slender forebody show that there are lots of asymmetric vortices formed at high angles of attack on the leeside of slender wing and body.Angle of attack and nose shape of bodies are key factors that asymmetric vortex occurs over slender bodies. |

| Keywords: | slender body forebody high angle of attack asymmetric vortex |
