摘      要：Ground effect dramatically improves the performance of the Wing-in-Ground(WIG)vehicles near the ***,making coordinate turnings in ground effect zone may raise complexity in flight *** Angle of Attack(AOA)and height are believed to be important *** find the impact of these factors,three straight rectangular wings with different aspect ratios are simulated via CFD *** results show that in normal situations,the rolling moment tends to level the wing but less effective with the decreasing AOA and changes its direction when the AOA is less than a height dependent *** yaw moment exhibits complex behavior because two different effects generate oppose *** rolling moment coefficient is more influenced by the ground if a wing has larger Aspect Ratio(AR)and works at low to medium *** yawing coefficient is always more influenced if the wing has larger AR regardless *** findings can provide basic guidance for the design of control system and enable aircraft designers to reshape the crafts to avoid or utilize this effect.
