基于Matlab软件中的优化算法和优化工具，针对风力机翼型通用型线集成表达式建立了优化数学模型。以风力机翼型的最大升阻比为优化设计目标函数，翼型形状控制方程的系数为设计变量，翼型的厚度和弯度为约束条件，设 计得到了相对厚度为18％的风力机翼型，并对其性能进行了计算分析。研究结果拓宽了风力机叶片翼型的设计思路和设计方法。(Based the Matlab software optimization algorithm and optimization tools for the integrated expression of the general profile of the wind turbine airfoil optimization model. Wind turbine airfoil maximum lift-drag ratio for the optimal design objective function coefficients of the equation of the airfoil shape control as design variables, airfoil thickness and curvature constraints, the design has been the relative thickness of 18 of wind turbine airfoil , and its performance is calculated and analyzed. The findings broaden the wind turbine blade airfoil design ideas and design methods.)
