对前缘后掠角为８０°的细长三角翼，迎角为３０°和４０°时不同滚转角下前缘涡的静态特性，及摇滚过程中的动态旋涡特性进行了流态显示和摄影记录。结果表明：在相同滚转角下，静态和动态情况下旋涡特性有相当大的差别；相对于静态而言翼摇滚过程中存在着旋涡特性的滞后效应；摇滚过程中旋涡垂向位置的滞后是明显的，而展向位置的滞后很小；还发现翼摇滚起始角对旋涡特性有较大影响．
The static characteristics of the leading edge vortex at different roll angles at 30 ° and 40 ° angle of attack for the slender delta wing with a swept angle of 80 ° and the dynamic vortex characteristics during the rocking process were observed and photographed recording. The results show that under the same roll angle, the vortex characteristics are quite different under static and dynamic conditions. The hysteresis effect of the vortex characteristics is present in the static state relative to the static state. The hysteresis of the vortex vertical position in the rock is obvious , While the hysteresis of the spreading position is very small. It is also found that the starting angle of wing rock has a great influence on the vortex characteristics.
