Blade tip clamp

Abstract

A blade tip clamp suitable for being attached to a wind turbine blade, the blade tip clamp comprising a clamp mechanism arranged to attach the blade tip clamp to a blade near the tip of the blade, said clamp mechanism having a first configuration where the clamp mechanism is expanded and where the blade tip clamp, when arranged on a blade, is not attached to the blade and a second configuration where the clamp mechanism is retracted and where the blade tip clamp, when arranged on a blade, is attached to the blade. The blade tip clamp further comprises at least one fan unit configured to generate an air flow to apply a force to the blade when the blade tip clamp is attached to the blade. In this way, the fan unit can be used to control the position of the blade in a simple and effective manner with lower power demands and lower required sizes than prior art devices.
