摘要：The design of a thick wind turbine airfoil is a multi-constraint and multi-objective optimal problem. In order to make the thick airfoil with a blunt trailing-edge have better aerodynamic and structural performance simultaneously, a new method for thick airfoil optimal design based on an improved MOPSO algorithm was presented in this paper. To show the performance of the new design technique, the optimization is accomplished on the wind turbine airfoils with a 40% maximum relative thickness, and the Pareto-optimal set is obtained. The representative airfoils are picked, analyzed, and compared with a traditional wind turbine airfoil (DU00-W2-401) at Re=2×106 for free and fixed transitions, the results show that the new airfoils have better performance than the DU00-W2-401.
