| 研究了经典动量 叶素理论和修正后的动量 叶素理论两种风力机叶片设计方法并进行了比较，对修正的动量 叶素理论计算的参数进行拟合，以某型号风力机为例，运用Matlab编程功能，引用设计范围更广的风力机翼型专用软件XFOIL，研究表明：拟合前后的弦长和扭角差异主要在靠近叶根部分；修正的动量 叶素理论相对于经典动量 叶素理论计算的轴向诱导因子，主要区别在于叶根和叶尖部分，切向诱导因子的影响非常小。 |

| Abstract: |
| In this paper, two theories of wind turbine blade design methods of classica blade element momentum theory and the corrected blade element momentum are compared, the parameters of the corrected blade element momentum theory are fitted ，In an example of a type of wind turbine,using matlab programming function,the specialized software xfoil of wind wing was used.The results show that the differences of chord length and twist angle before and after are mainly near the root of leaf; the main difference of the axial induction factor between classical blade element momentum theory and corrected blade element momentum theory is that the blade root and the tip portion, the effect of the tangential induction factor is very small. |
