Abstract

A wind turbine rotor blade comprising: a blade body; a flap for modifying the aerodynamic surface of the rotor blade, a part of which forms a part of a trailing edge of the rotor blade, the flap being deflectable relative to the blade body;an actuation device for deflecting the flap from a first position to a second position;the actuation device comprising a linear motor having a stationary part connected to the blade body and a translating part for movement along a straight or curved path relative to the stationary part, the translating part being connected to the flap, and the actuation device is located inside the rotor blade;wherein the actuation device deflects the flap when the translating part moves relative to the stationary part.
