摘　　要：本文在风力机的叶尖上通过添加V型平板小翼实验,提高了风力机的输出功率。在风洞实验研究中,进行了不同长度和宽度、不同前张角和后张角小翼的探索。实验表明小翼对风力机在一定尖速比λ范围内可以提高功率系数C_p值。In this paper, an experiment of adding a V type tip vane to the blade of the Horizontal Axis wind turbine is carried on. It turns out to be helpful to the dynamic augmentation of the output power. In this experiment of wind tunnel, we try to find out the rule by changing the length and width of the tip vanes at different forward pitch angles and backward pitch angles. The experiment results show that in certain tip speed ratio the tip vane does well to the dynamic augmentation of the output power.
