Abstract
Gyromill type wind turbine generally includes an over revolution problem. To inhibit this problem, a revolution speed of wind turbine is controlled by a mechanical break system or an electric-magnetic break system. In this study, to inhibit the over revolution problem, a new gyromill wind turbine, which can be controlled autonomously by changing the wing pitching angle by the centrifugal force, were developed. As the results of this study, it was found that the aerodynamic autonomous control system of the developed wind turbine works very well and this system will bring safer and cheaper wind turbine.
