Abstract
A wind turbine rotor blade comprising: a blade body; a flap for modifying the aerodynamic surface of the rotor blade, a part of the flap forming 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 stationary part connected to the blade body and a moving part arranged to be connected to the flap, the actuation device being located inside the rotor blade; the stationary part comprising a magnet or an electrical conductor and the moving part comprising the other of the magnet or the electrical conductor, the stationary part and the moving part forming a voice coil actuator, and the moving part moves in a electro-magnetic field formed by the magnet and the electrical conductor; wherein the actuation device deflects the flap when the moving part moves relative to the stationary part when a current is applied to the electrical conductor.
Claims (9)
1. A wind turbine rotor blade comprising: a blade body; a flap for modifying the aerodynamic surface of the rotor blade, a part of the flap forming 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 stationary part connected to the blade body and a moving part arranged to be connected to the flap, the actuation device being located inside the rotor blade; the stationary part comprising a magnet or an electrical conductor and the moving part comprising the other of the magnet or the electrical conductor, the stationary part and the moving part forming a voice coil actuator, and the moving part moves in a electro-magnetic field formed by the magnet and the electrical conductor; wherein the actuation device deflects the flap when the moving part moves relative to the stationary part when a current is applied to the electrical conductor.
2. A wind turbine rotor blade according to claim 1, wherein the flap is connected with a plurality of moving parts interacting with a plurality of stationary parts.
3. A wind turbine rotor blade according to claim 1 or claim 2, wherein the actuation device is located adjacent to the flap.
4. A wind turbine rotor blade according to any one of the preceding claims, wherein the flap has a flap length in the longitudinal direction of the rotor blade, and the actuation device is located within the rotor blade, in an area bounded at least partly by the flap length.
5. A wind turbine rotor blade according to any one of the preceding claims, wherein the flap comprises a trailing edge and a front end opposite the flap trailing edge, and the front end of the flap is pivotally connected to the blade body.
6. A wind turbine rotor blade according to claim 5, wherein the flap is separated from the actuation device in a chordwise direction of the rotor blade, the flap being connected to the moving part of the actuation device by a connection arm, the connection arm extending in the chordwise direction of the rotor blade; a first end of the connection arm being attached to the moving part of the actuation device; and a second end of the connection arm is attached to the front end of the flap such that movement of the connection arm in a direction substantially corresponding to the thickness of the rotor blade causes the flap to pivot about its front end.
7. A wind turbine rotor blade according to any one of the preceding claims, wherein the rotor blade has a plurality of flaps and each flap is actuated by a separate actuation device.
8. A wind turbine rotor blade according to any of claims 1 to 6, wherein the rotor blade has a plurality of flaps and the plurality of flaps are actuated by a single actuation device.
9. A wind turbine generator having at least one wind turbine rotor blade according to any one of the preceding claims.
