Inverse optimization of supersonic wing design with twist specification

A design optimization system for a supersonic wing has been developed. The present design system consists of the supersonic inverse design method and the Multiple-Objective Genetic Algorithm (MOGA) code for target pressure optimization. Furthermore, a wing twist specification technique is introduced to the present inverse design method by taking advantage of the non-uniqueness of three-dimensional aerodynamic inverse problems. With this method, a designer can select a wing that is easy to be manufactured and aerodynamically optimal. The designed wing shows better performance than the second baseline wing of National Aerospace Laboratory's (NAL) scaled supersonic experimental airplane program.
