摘　　要：以动量-叶素理论为基础建立了水平轴风力机叶片气动计算模型,同时考虑叶尖损失、叶根损失及失速状态下动量理论的失效对动量-叶素理论进行修正,通过对NREL10 m风力机叶片进行气动性能计算,通过与实验数据的对比,探讨模型的准确性。Based on the traditional Blade Element-Momentum theory, an improved method of aerodynamic calculation about blades of the horizontal axis wind turbine is presented in this paper. To account for tip loss, hub loss and the invalidation of momentum theory during the operation of the wind turbine operating in stall state, the BEM theory was amended. The aerodynamic performance of the 10 m-blade of wind turbine in NREL with was calculated using this method. Accuracy of the model was discussed by comparing between the results and experience data.
