风能的利用了对垂直轴风力涡轮机发电系统的风力发电技术的悠久传统的重新发现。本课题根据风力发电性能和流体力学理论，提出了一种利用腔内风能二次驱动的垂直轴风力机涡轮机三爪式风轮。设计了风轮的结构和参数。为了研究风轮的性能，制作了与风轮真实的尺寸相似的简化试验模型。还采用了简易开口直流风洞，该风洞由风洞、风轮试验台和测试仪器组成。通过风洞试验，验证了该模型在空载和有载条件下的起动风速、起动转矩、风速与功率、叶尖速比和转子功率系数之间的相关性等特性。试验结果表明，该风轮具有结构简单、风力发电效率高、风力发电效率高等优点。
The utilisation of wind energy draws on the rediscovery of a long tradition of wind power technology to vertical-axis wind turbine generation system. A three-hastate wind wheel for vertical-axis wind turbine, which can be driven by the intra-cavity wind energy secondarily, is proposed according to the wind energy performance and the hydrodynamics theory in this research project. Structure and parameters of the wind wheel are designed. A simplified test model is made similar to the real dimension of the wind wheel to investigate its performance. A simple opening straight-flow wind tunnel is also used which is composed of wind tunnel, wind wheel test bed and testing instruments. Characteristics of the model are testified in wind tunnel tests while it is under or without loads, which include start-up wind speed, torque, correlations among wind speed, power, tip speed ratio and rotor power coefficient, etc. The experimental results show that this type of wind wheel has many advantages such as simple structure...
