Abstract
The parameterization of airfoil geometry has a profound influence on optimization results and calculation efficiency. A good parametric method should have a large optimization space, good local control ability, fewer design variables, and at the same time ensure the requirements of geometric shape smoothness in the optimization process. The class and Shape Transformation method proposed by Kulfan has been widely used for its excellent robustness and smooth geometric description ability. This method can ensure that the leading edge radii of the upper and lower airfoil surfaces are equal. In this paper, NACA0012 and RAE2822 airfoil are fitted with different order shape functions. An application was carried out to generate a new airfoil mesh based on an existing mesh and a new airfoil using CST method and dynamic mesh technology.
