中文摘要：
应用环境风洞，对几种不同的聚能-遮蔽模式及几种不同的风轮模型进行了吹风实验，获得了低风速条件下该类风力机风能利用特性的系列实验数据。研究表明，单S型（两个弧形叶片）的风力机的风能利用率高于多个弧形叶片的风力机的风能利用率；适当的聚能-遮蔽模式可以实现微风启动，并显著地提高风能利用率。
英文摘要：
Experiments have been carried out on wind wheel with several types of wind collectionshield pattern and different types of wind wheels in the environmental wind tunnel. A series of experimental data of the special kind of wind wheel are obtained under the low wind speed condition. This research indicates that the wind energy utilization factor of the wind wheel with two-blades （S type） is higher than that with multi-blades. The wind wheel with proper wind collection-shield pattern can startup at low speed, and can raise the wind energy utilization factor remarkably.
