The morphing wing changes the geometrical shape seamlessly and continuously to improve the aerodynamic performance. Several studies have been conducted with variety of approaches. This study focuses on obtaining the optimum airfoil shape for the morphing wing using the corrugated structures arranged in the rear side of the airfoil. For numerical efficiency, SAO (sequential approximate optimization) method using RBF (radial basis function) network is adopted. The airfoil shape is modeled by using nonuniform rational basis spline (NURBS) curves and the passing points are adopted as design variables. Through numerical examples, the validity of the optimization method is demonstrated.
