VERTICAL AXIS WIND TURBINE ABSTRACT OF THE DISCLOSURE Wind turbines are largely divided into vertical axiw wind turbines and propeller (horizontal axis) wind turbines. The present invention discloses a vertical axis high speed wind turbine provided with rotational speed control systems. This vertical axis wind turbine is formed by having blades of a proper airfoil fitted to respective supporting arms provided radially from a vertical rotating shaft by keeping the blade span-wise direction in parallel with the shaft and being provided with aerodynamic control elements operating manually or automatically to control the rotational speed of the turbine.
