This article constructed an aerodynamic optimization platform oriented to the design of aircraft high lift devices, and use this platform to design the gap parameters of 30P30N three-element airfoil with a nested double cycle worklfow. During the optimization process, the platform use adaptive genetic algorithms improved by sensitivity analysis as its main optimization method. The results indicated that the lift-drag ratio of this airfoil has been signiifcantly improved, and this optimization is suitable for kinds of multi-element airfoils’ high lift devices.
