Multivane windmill
Patent
·
OSTI ID:5149110
A windmill is described which has a plurality of pairs of diametrically opposed vanes mounted for rotation about a horizontal axis in alignment with the wind. The pairs of vanes are supported in uniformly spaced relationship to each other axially of the axis of rotation and each successive pair is indexed circumferentially in the direction of rotation relative to the prior pair. The vanes are automatically moved to a less efficient position as the speed of the wind increases to limit the maximum speed of the windmill.
