In this study, a new type of wind turbine utilizing magnus effect on rotating cylinders is introduced. For the wind turbine, spiral structures are equipped on cylinder surfaces to enhance magnus effect. At first, Lift and drag forces on a rotating cylinder are measured to evaluate aerodynamic characteristics of the cylinder. As the result, it was indicated that the lift force is enhanced for lower tip speed ratio of the cylinder by the spiral structures though the drag force is also gained. In the second stage, a test wind turbine with five rotating cylinders was constructed to estimate the basic characteristics of the magnus wind turbine with spiral structures. As the results, it was indicated that the effect of rotating speed of the cylinder is basically positive to power and torque coefficients for the test condition and the basic characteristic of the wind turbine is torque subjected.
