The characteristics of a gyro-mil wind turbine whose rotating blades are elastically deformable are presented. The each blade consists of ordinal rigid wing and elastically deformable thin plates. The performance tests are performed under the wind generated by 6 fans. This type of gyro-mill turbine has very large torque when the rotation speed is low, but the torque drops sharply when the rotating speed becomes larger. In order to prevent the sharp drop of the torque, the deformation of the elastic plate in outside direction due to the centrifugal force must be prevented and rigid plates for preventing the deformation are shown to be successful. When the wind is discontinuous or fluctuates like the natural wind, the performance of presented wind turbine with elastic plates is shown to be much higher.
