Abstract

Some parameterized methods for airfoil were investigated in this paper, which contain linear shape function method, PARSEC method, orthogonal basis function method and Class-Shape function Transformation method. The fitting accuracy of these parameterized methods was contrasted in symmetric airfoil, cambered airfoil and supercritical airfoil. The fitting results show that the fitting accuracy of CST method is better than other parameterized methods for airfoil. The aerodynamic analysis models of these parameterized methods for airfoil were constructed. The Latin hypercube method was employed to get a set of sample points. The aerodynamic Kriging models of these parameterized methods for airfoil were built. The airfoil was optimized by combining genetic algorithm with Kriging model. These parameterized methods for airfoil were validated by two applications.

Key words： orthogonal basis function; Class-Shape function Transformation method; fitting accuracy; Kriging model; airfoil design optimization
