Abstract
A rotor blade for a wind turbine having an aerodynamic profile which extends from a blade root up to a blade tip and has a leading edge and a trailing edge. An adjustable aerodynamic flap, which can be adjusted between a retracted and a deployed position by means of a flap drive, is provided on the rotor blade. The flap drive comprises a passive control system which controls a flap position depending on rotation speed. The passive control system of the flap drive is low-maintenance and does not interfere with the safety concept of a wind turbine. In comparison with a reference rotor blade without a flap, the rotor blade has increased lift at low wind speeds.
Claims22
A rotor blade for a wind turbine, comprising:
- having
- a body having an aerodynamic profile extending from a blade root to a blade tip, and having a leading edge and a trailing edge,
- an adjustable aerodynamic flap arranged on the body, and
- a flap drive configured to adjust the adjustable aerodynamic flap between a retracted position and a deployed position, wherein the flap drive comprises a passive control system configured to control a flap position depending on rotation speed.
An assembly comprising:
- an aerodynamic trailing edge flap and a flap drive, and is configured for mounting on a trailing edge of a rotor blade for a wind turbine.
