| 摘 要： | 本文介绍了头部旋转对大迎角不对称涡系影响的观测结果,说明了由此而抑制大迎角不对称涡系的机理。 实验结果表明,头部旋转对细长体无侧滑大迎角不对称涡系涡迹的影响是:随头部的逐渐转动,涡系的不对称发生了周期性变化;此时,由于涡不可能迅速改变状态,从而抑制、甚至接近消除了大迎角时出现的涡系不对称现象。

| Abstract: | Experimental results of spin nose of a slender body at high angle of attack are presented,and the formation mechanism of the spatial vortexes are also explained in this paper.Experimental results show that the vortex cannot be changed rapidly with the nose spin rate,therefore the asymmetric vortexes on slender body at high angle of attack can be inhibited and approach to vanished. |

| Keywords: | vortex flow spatial vortex aerodynamics at high angle of attack slender body |
