Keywords: complex optimum method, Navier-Stokes equation, multi-point optimization problem

An airfoil shape design method that couples viscous flow analysis and a complex optimum method is described in this paper. The method is applied to search an airfoil geometry with improved aerodynamic performance at single or multiple design-point while the specified design constraints being satisfied.
