为实现快速计算叶片给定运行攻角所需要的桨距角，提出了一种基于动量叶素理论改进的叶片气动特性计算方法，该方法的优势为在迭代计算轴向诱导因子与切向诱导因子过程中减少了查询翼型气动特性的次数。改进的动量叶素理论计算方法比经典动量叶素理论计算方法，能够快速计算实现叶片运行攻角所需要的桨距角。利用该方法对叶片气动特性进行的计算结果与GH Bladed软件的计算结果十分接近，且提高了计算速度。

To achieve rapid calculation of the blade pitch angle when given the operation atack angle, an improved calculation method of blades aerodynamic characteristics based on blade element momentum theory is proposed. Te advantage of this method is that it reduces the times to query the airfoil aerodynamic characteristics in the process of iterative calculation for axial induced factor and tangential induced factor. Te calculation of the pitch angle of the blades when given the atack angle with the improved method is faster than that with the classical blade element momentum theory. Te calculating results of the blade aerodynamic characteristics with this improved method and GH Bladed software are consistent, and the computing speed is improved with the improved method.
