VERTICAL AXIS WIND TURBINE WITH VARIABLE PITCH MECHANISM

摘要

A vertical axis wind turbine; said turbine including a vertical central shaft and a plurality of vertical blades; each of said vertical blades supported by at least one radial supporting arm extending from said central shaft; characterized in that angular disposition of each of said blades relative to its respective said at least one radial supporting arm, is controlled by a control mechanism; said mechanism including at least two differentially resilient elements and a damping element.
