风力涡轮机空气动力学设计的一个重要因素是使用专门定制的翼型来提高能量捕获率并降低能源成本。这项工作的重点是通过数值优化来设计风力涡轮机的厚翼型。提出了一种混合方案，将遗传算法和基于梯度的算法结合在一起，以提高设计的准确性和可靠性。首先，描述该类翼型的要求和约束；然后，提出了混合方法。这项工作的最后部分致力于说明有关新型厚翼型设计的数值示例。对结果进行了讨论并与现有翼型进行比较。
One important element in the aerodynamic design of wind turbines is the use of specially tailored airfoils to increase the ratio of energy capture and reduce the cost of energy. This work is focused on the design of thick airfoils for wind turbines by using numerical optimization. A hybrid scheme is proposed in which genetic and gradient-based algorithms are combined together to improve the accuracy and the reliability of the design. First, the requirements and the constraints for this class of airfoils are described; then, the hybrid approach is presented. The final part of this work is dedicated to illustrate a numerical example regarding the design of a new thick airfoil. The results are discussed and compared to existing airfoils.
