为了探索风轮园弧形叶片的不同弦高比和叶片的正面形状对风轮性能的影响,我们设计并制造了10个风轮模型,1988年末,在中国农机研究院风洞试验室进行了试验。本文将对模型的设计、试验和得到的结果,作以论述。一、试验研究的理论基础我们研究的风轮是水平轴的,它旋转的动力主要是靠叶片的升力。图一所示为风轮的垂直和水平4个叶片示意投影图,图中代号含义如下: In order to explore the effect of different chord-height ratio and the frontal shape of blades on the performance of wind turbines, we designed and manufactured 10 rotor models. At the end of 1988, we carried out the wind tunnel test at China Academy of Agricultural Machinery test. This article will be the model design, test and the results obtained, to be discussed. First, the theoretical basis of experimental research Wind turbine is horizontal axis of our study, it is mainly driven by the blade lift force. Figure 1 shows the vertical and horizontal wind wheel 4 schematic projection map, the code meaning is as follows:
