The formulation of the aeroelastic optimization of wing structure was carried out. The purpose of this optimization is to obtain a sufficient flutter speed and natural frequency with minimum weight and satisfy the requirements of maximum stresses and maximum deflections. The optimization was performed with continue (dimensions of ribs, spars, caps, skin thickness) and discrete (number of the ribs and caps) design variables. The structure was modeled by equivalent plate model (EPM) and the unsteady aerodynamic forces were determined using lifting-line theory. Modified genetic algorithms (GAs) with special method to handle the constraints were implemented. The optimization was applied on the several wings and the results were compared with those from references or verificated with other Methods.
