ACTUATOR SYSTEM FOR FLAP ON ROTOR BLADE OF A WIND TURBINE

WIPO Patent Application WO/2010/151230

A3

An actuator system, a wind turbine blade, and a wind turbine are provided. The actuator system includes a first lever having a first arm pivotable about a first pivot axis, and a second arm extending away from the first arm. The second arm is fixed to the first arm at a position spaced away from the first pivot axis. The actuator system also includes an actuator element slidably coupled to the second arm via a coupling element. Upon activation of the actuator element, the actuator element is adapted to push the coupling element towards to or pull the coupling element away from the second arm such that the coupling element applies pressure on the second arm and performs a sliding movement along the second arm. An actuator output of the actuator system can be increased.
