摘要
本文绘出不同后掠角的三角翼模型在低速风洞中大幅度俯仰运动时和带振动鸭翼飞机模型主翼面上的动态流动显示；分析了动态流动迟滞特性的流动机理及缩减频率的影响和鸭翼涡对主翼涡的干扰影响及随鸭翼振动时主翼涡位置、强度、涡破散点位置的变化。
In this paper the dynamic vortex flow visualization for oscillating delta-wing models with large amplitude and for oscillating canard was summarized.And the flow mechanism of dynamic aerodynamic hysteresis characteristic was analysed.At the canard oscillation the interference of canard vortex and wing vortex, the change of position, strength and burst point position of wing vortex with vortex with canard vibration was analysed also.
