摘　　要： 在研究以前工作的基础上,探讨了在风洞中采用小型风力机整机在叶片上加襟翼来提高桨叶气动效率、增加功率可行性的实验研究,实验是在汕头大学的双速回流风洞中进行的。作者设计了实验方案,测量了机组在不同来流和襟翼高度工况下的输出功率。并和没有襟翼时的输出功率进行了对比。最后采用风力机气动数值计算结果。对实验结果进行了理论上的说明。 On the basis of the previous research work, the purpose of this paper is to discuss the feasibility experimental research of the power and efficiency augmentation of a small horizontal axis wind turbine by adding small flaps to its blades. The rated power of the small wind turbine is about 300W and the unit has two blades. The experiment with a small trailing edge flap is conducted in a low-speed, closed-loop wind tunnel at Shantou University. The experimental of the output power at various incoming wind speed and different flaps heights were designed. The output powers with additional flaps were compared with the original values. The experimental results were analyzed with numerical aerodynamic performance calculation of wind turbine.
