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.

Key words: oscillating delta wing, patter n, aerodynamics char acteristics, high angle of atta ck, time scale
