| 摘 要： | 结合层流翼型与钝尾缘的特性,通过Hicks-Henne型函数对翼型参数化修型,基于多岛遗传算法及Xfoil气动分析,针对大型水平轴风力机翼型进行多目标函数、多设计工况、多约束条件下的优化设计,得到适用于大型风力机的高性能翼型族（USST翼型族）。其升阻比在大多数攻角下均高于同厚度的FFA、DU系列等现有风力机翼型族,且在同样的升力系数下具有更大的升阻比。最后为考核优化设计得到的翼型族,采用数值模拟方法对优化结果进行验证,证明设计得到的新型风力机翼型族具有优越的气动性能。

| Abstract: | Combining the characteristics of laminar airfoil and blunt trailing edge, the airfoil is parametrically modified by Hicks-Henne type function. Based on the multi-island genetic algorithm and Xfoil aerodynamic analysis, the optimal design under multi-objective functions, multiple design conditions and multiple constraints conditions is carried out for the airfoil of large horizontal axis wind turbines. By doing that, a high-performance airfoil family（USST airfoil family） suitable for large wind turbines is obtained. Its lift-drag ratio is higher than that of the existing wind turbine airfoil families such as the FFA and DU series at most angles of attack. The lift coefficient has a larger lift-to-drag ratio, especially in the case of a high lift coefficient. Finally, in order to evaluate the optimized design of the airfoil family, based on the turbulence transition model （Transition SST）, the optimization results are verified by the numerical simulation method, which proves that the new wind turbine airfoil family designed in this paper has superior aerodynamic performance. |
