  • Tip brake mechanism for a wind generator blade
    Patent number: 4952119
    Abstract: A tip brake is described for use on the blade of a wind generator so that the tip will be rotated relative to the remainder of the blade to slow the rotation of the rotor. The tip of the blade is rotatable, about its longitudinal axis, with respect to the remainder of the blade. A brake mechanism interconnects the blade tip with the remainder of the blade to cause the blade tip to be rotated when the blade is subjected to a predetermined amount of centrifugal force. Once the blade tip has been deployed to slow rotation of the rotor, it will remain deployed until the wind becomes very low or the rotor is manually slowed so that the spring can cause the tip to be reset.
