As the large scale wind turbine generator systems over one mega-watt spread in the world, development of more effective and low cost wind turbines are required. In the mechanical point of view, more precise estimation of the aerodynamic load and fatigue life is indispensable. In order to reduce the cost, the weight and the aerodynamic load of the rotor blade and the tower, "flexible structural design" has been proposed. The purpose of the study is to develop the reliable and powerful tool for the design and estimation of the load calculation on the horizontal axis wind turbine. In the present paper, the influence of the blade oscillation to the flow field around the rotor blade and the blade load are analyzed by a panel method with free wake model along with one dimensional blade oscillation model.
