可伸缩叶片小型垂直轴风力机设计

Design of a Small VAWT with Adjustable Blades

针对微小型风力发电机组的市场应用,结合叶素—动量理论,在满足风电机组输出电量的前提下,对垂直轴小型风电设备叶轮进行改良设计。相比于传统的垂直轴风力机更便于携带,叶片可以自由伸缩,存储或运输时可以节省大量空间,并且风轮叶片能根据风速变化而自动调节,保证输出的电压在一个稳定区间之内。

Aiming at the prospect for the small VAWTs,a newtype VAWT with adjustable blades was designed. Compared with the traditional ones,the newtype is much easier to be carried. Owing to the adjustable blades,it can save a lot of space when transported or stored. Blades can be adjusted automatically with the mutative wind to ensure the output voltage in a stable region.
