Multi-objective Aerodynamic Design Optimization for Airfoil Using Kriging Model
Wenping Song · Aeronautical Computing Technique · 2009
In this paper,a surrogate model technical based on Kriging model is applied to the airfoil design optimization problem,and a new aerodynamic design optimization method is developed which is of well numerical stability and efficiency.The Latin hypercube method is employed to construct the initial sample points in the design space,the response value are solved by a compressible 2-D RANS program.The hicks-henne functions are used to define the parameterized airfoil geometry,Minimize the drag under the constrained condition,the application indicates that the method is not only feasible,but also has good efficiency.Compared with the traditional design method,the proposed method could decrease the time cost apparently.
