摘要
本文将动量-叶素理论推广应用于计算水平轴风车叶轮有侧偏角或上仰角时的气动力。计算结果与实验数据比较表明:这种计算方法简单快速,并有一定的准确度。所得结果对合理设计小型水平轴风车侧偏式或上仰式限速机构很有用。
Based on the traditional Momentum-Blade Element theory, an improved method of aerodynamic calculation about the horizontal axis wind turbine in yaw or in pitch-up is presented in this paper. The com-parision of calculated results with experimental data shows that this method is effective and accurate. The calculated results are very useful for designing of the overspeed control mechnism of utilizing side turning rotor.
