摘　　要：在低速风洞内,分别对齐莫曼翼和反齐莫曼翼的气动特性进行了测量,并应用PIV测试技术测量了两种微型飞行器机翼的空间流场,给出了空间流场的速度矢量图、涡量图和流线图。通过对比分析给出了两种机翼气动特性产生差别的主要流动机理。The aerodynamic characteristics and the leeward flow field of Zimmerman wing and inverse Zimmerman wing were investigated in NUAA unsteady wind tunnel through the aerodynamic forces measurements and PIV tests. The pictures of velocity vector, vorticity, stream line are presented. The results show that the flow fields of Zimmerman wing and inverse Zimmerman wing are controlled by the leading-edge vortex at the middle angle of attack. With the angle of attack increasing, the flow of the inverse Zimmerman wing separate firstly, but the flow of the Zimmerman wing is still controlled by the leading-edge vortex. So the stall of Zimmerman wing is delayed.
