| Abstract: | Force measurement results of oscillating delta wings at angle of attack ranging from 0°～90° are presented. Furthermore, effects of leading edge swept angle, oscillating frequency and axle location about which a delta wing oscillates on normal coefficient of the delta wing are given and the mechanism of the effect is discussed. |

| Keywords: | oscillating delta wing pattern aerodynamics characteristics high angle of attack time scale |
