以改进Glauert理论为目的,以有限叶片数、变环量及扩散状的尾流模型为依据,建立和求解描述该模型的积分微分方程,获得一种确定水平轴风力机叶片气动外形设计的新方法。应用该设计方法对某1.5MW风力机叶片进行气动外形设计,并将其气动计算结果与其他方法的结果进行比较,以说明所给方法的有效性。该研究成果为大功率风力机叶片的设计提供了理论依据,为风力机叶片的研究和实际应用开拓了前景。
In order to improve Glauert theory, the integral differential equation describing and describing the model is established and solved based on the finite leaf number, variable ring volume and divergent wake model, and a new method to determine the aerodynamic profile of horizontal axis wind turbine blade is obtained method. The aerodynamic shape design of a 1.5 MW wind turbine blade is applied with this design method. The aerodynamic calculation results are compared with the results of other methods to show the effectiveness of the proposed method. The research results provide a theoretical basis for the design of high-power wind turbine blades and open up the prospect for the research and practical application of wind turbine blades.
