| 摘要 |
The invention describes a wind turbine rotor blade comprising a root portion (10) and an airfoil portion (19), which blade (1) comprises a thickened zone (TZ) in which the blade (1) has a thickness coefficient of at least 0.45, which thickened zone (TZ) extends outward from an inner hub end of the blade (1) into the airfoil portion (19) of the blade (1); and an airflow correction arrangement (2, 3) arranged on a pressure side (11) of the blade (1) over at least a portion of the thickened zone (TZ), which airflow correction arrangement (2, 3) comprises a spoiler (3) realised to increase blade lift and a vortex generator (2) arranged between a leading edge (12) and the trailing edge (13) and realised to maintain an attached airflow (42) between the vortex generator (2) and the spoiler (3). The invention also describes a wind turbine with at least one such rotor blade (1). The invention also describes an airflow correction arrangement (2, 3) for correcting the airflow over the pressure side (11) of a wind turbine rotor blade (1) for a region of the blade (1) having a thickness coefficient of at least 0.45. |
