VERTICAL AXIS WIND TURBINE ABSTRACT OF THE DISCLOSURE Wind turbines are largely divided into vertical axis wind turbines and propeller (horizontal axis) wind turbines. The present invention discloses a vertical axis high speed wind turbine provided with a starting and braking control system. This vertical axis wind turbine is formed by having blades of a proper airfoil fitted to respective supporting arms provided radially from a vertical rotary axis by keeping the blade span- wise direction in parallel with said axis and being provided with a low speed control windmill in which the radial position of each operating piece varies with a centrifugal force produced by the rotation of said vertical rotary axis.
