摘要
对 8 0°三角翼滚摆的非定常流场进行常规流动显示和定量流动显示即PIV测量 ,获得了对于引起和维持滚摆的气动机理的新认识 ,即引起和维持滚摆的气动机理不仅在于前缘分离涡相对翼面位置的动态迟滞特性 。
The paper presents result of conventional flow visualization and quantitative flow visualization namely Particle Image Velocimetry measurements on the unsteady flow fields of a 80° delta wing rock. The flow phenomenon mechanisms causing and sustaining the wing rock is analyzed. This is perhaps not only the dynamic hysteresis of the leading edge vortex location respective to the wing surface but also the dynamic hysteresis of the vortex strength.
