Experiments on Savonius rotor and Bent-blade rotor with two curved plate blades which were bent twice by two corners were conducted to confirm characteristics and to augment output power. From the results of experiments, the rotors with different bend angle showed some interesting behaviors to develop the action region in the rotational speed, and to augment the output power coefficient compared with the normal rotor. At the bend angle of 60 degrees, the output power coefficient reached the value of 1.13 times that of the normal Savonius rotor.
