摘　　要：为设计出气动性能优异的风力机翼型,运用CST参数化方法表述翼型外形特征以控制翼型型线,利用自适应遗传算法耦合XFOIL软件的翼型优化方法,以翼型NACA 63-215为优化算例,在设计工况下寻优,得到一种升力系数、阻力系数、升阻比、力矩等气动特性均较NACA 63-215更优的翼型,证明了该优化方法的可行性,为风力机翼型优化设计提供了参考。For designing of the airfoil with better aerodynamic characteristics,the airfoil optimization program of adaptive genetic algorithm coupled with XFOIL software has been adapted which controls the airfoil type line using the CST parameterization method.Taking NACA 63-215 airfoil for an example,under the design operating condition,an airfoil whose aerodynamic characteristics（lift coefficient,drag coefficient,lift drag ratio and moment of force）are more outstanding is optimized.The feasibility of the optimization program is proved,which provides a reference for the airfoil optimization design.
