摘要
结合翼型泛函集成理论与叶片截面刚度矩阵数学计算模型,提出了风力机中等厚度翼型气动性能与结构刚度特性的一体化设计方法,实现了翼型气动性能与叶片截面刚度特性的同时提高。对考虑叶片截面铺层参数变化设计的WQ-B300翼型与DU97-W-300翼型进行了气动性能与结构刚度特性对比分析,结果表明:相比于DU97-W-300翼型,WQ-B300翼型的气动性能与叶片截面刚度性能均有显著提高,其挥舞刚度和摆振刚度分别提高了6.2%和8.4%,验证了该设计方法的可行性,给风力机中等厚度及大厚度翼型设计提供了一种思路。
Combining the airfoil functional integration theory and the mathematical model of the blade cross-section stiffness matrix,an integrated design method of aerodynamic performance and structural stiffness characteristics for the medium thickness airfoils was presented.It may make the aerodynamic performance and the blade cross-sectional stiffness characteristics both increase.The aerodynamic performance and structural characteristic of WQ-B300 airfoils which were designed considering the change of blade cross-sectional ply parameters were compared and analyzed with DU97-W-300 airfoils.Results show that compared with DU97-W-300 airfoils,the aerodynamic performance and blade cross-sectional stiffness performance of WQ-B300 airfoils improve largely.The flapwise stiffness and edgewise stiffness are increased by 6.2%and 8.4%respectively.This study verifies the feasibility of the novel design method,and provides a good design idea for wind turbine airfoils and blade structural properties with medium or large thickness.
