A new method for shape optimization with relatively large number of design variables is proposed. For effective utilization of a richer design space, it is proposed that the number of design variables be increased gradually. This method is demonstrated by designing high lift airfoils for Re = 1 × 103 and 1 × 104 at a = 4°. Corrugations on the upper surface of the optimal airfoil promote generation of small vortices that lead to higher aerodynamic performance.
