Abstract
A rotor blade of a wind turbine is provided, wherein the rotor blade has a flow deflection device for influencing an airflow flowing from the leading edge section of the rotor blade to the trailing edge section of the rotor blade. The flow deflection device passively changes its configuration depending on the bending of the rotor blade. Furthermore, the airflow is influenced such that load on the rotor blade is reduced. Furthermore, a method to reduce load on a rotor blade of a wind turbine is provided.
Claims12
A rotor blade of a wind turbine, wherein the rotor blade comprises
- a flow deflection device for influencing an airflow flowing from the leading edge section of the rotor blade to the trailing edge section of the rotor blade,
- wherein the flow deflection device passively changes its configuration depending on the bending of the rotor blade, and
- wherein the airflow is influenced such that load on the rotor blade is reduced.
A method to reduce load on a rotor blade of a wind turbine, wherein an airflow flowing from the leading edge section of the rotor blade to the trailing edge section of the rotor blade is passively influenced by a flow deflection device, the method comprising:
- inducing a change of the configuration of the flow deflection device by bending of the rotor blade, and
- influencing the airflow such that load on the rotor blade is reduced.
