In this paper, multi-objective aerodynamic design of the multi-element airfoil based on Kriging model is carried out. For flow analysis, a 2-D N-S solver using zonal patched grids which produced automatically and efficiently is applied. Utilizing the above method, the aerodynamic characteristic of the airfoil is greatly improved.
