Bolie, V W

An improved type of wind turbine comprises a rotating assembly attached to a central hub, which is supported for rotation in a horizontal plane about a vertical axis, in a bearing on top of a tower of selected elevation. The rotating assembly comprises at least two radial spokes or arms positioned from each other at equal angles in a horizontal plane. The outer ends of the arms are attached to a connector assembly which generally is in the form of a u-shaped member lying in a vertical plane. A long thin vertically oriented airfoil is mounted on the ends of each connector, the plane of the chord of the airfoil is perpendicular to the axis of the arm which supports it. A torque shaft is attached at the axis of the hub and passes axially downwardly through the tower to an energy conversion device mounted in a housing on the base, which supports the tower. The tower may be guyed by means of cables, etc. Which are attached below the level of the rotating assembly. Means are provided for using wind power to bring the rotating assembly up to a selected operating speed. Braking vanes are provided to limit the top speed of rotation of the assembly.
