A method is presented for the optimum aeroelastic design of a flapping wing employing lifting-surface theory as an aerodynamic tool and the complex method as the optimization algorithm. The method is applied to the optimum design of a flapping wing of a Kite Hawk (Milvus migrans) UAV (Unmanned Aerial Vehicle) and the optimum thickness distribution of the main-spar is determined. As the result of the optimization, a high propulsive efficiency of 75 percent is attained considering only dihedral flapping of the main spar. By evaluating the viscous effect for this optimum design using a three-dimensional Navier-Stokes code, the effectiveness of the design is confirmed.
