Wing is the main part of aircraft for lift. It bears not only the lift but also the concentrated loads from the engine,landing gear and other devices. The optimization of wing is to design a structure that meets all the demands for using with less structure weight. This paper introduces a method for the optimization design of composite wing with multiple load cases and large scale design variables. An optimization process is built to carry out this method ,and finally it is proved by the optimization design of a wing skin with 105 design variables and 30 load cases.
