| Abstract: | 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. |
