摘要
对80°和8O°／45°尖前缘平板三角器模型在低速风洞中进行滚摆试验，包括自激滚摆角时间历程测量，强边滚摆流动显示和翼面非定常压力测量。分析滚摆流动机理以及运动参数对涡流场的影响。
An experimental investigation on wing rock of a 80°and80°/45° delta p1ate wing with sharp leading edge was conducted in thewind tunnel. The free-to-roll angle time history, unsteady surface pressure distribution and vortex flow visualization were measured and performed. The wing rock flow mechanism was analysed and thc effectof wing rock motion on the flow was discussed also.
