WIND TURBINE ROTOR BLADE, WIND TURBINE WITH NUMBER ROTOR BLADES AND AIRFLOW CORRECTION PROVISION

摘要

WIND TURBINE ROTOR BLADE, WIND TURBINE WITH NUMBER OF ROTOR BLADES AND AIRFLOW CORRECTION ARRANGEMENT The present invention relates to a wind turbine rotor blade that comprises a root portion (10) and an airfoil portion (19), in which blade (1) comprises a thick zone (TZ) in which the blade (1) has a thickness coefficient of at least 0.45, in which the thick zone (TZ) extends outwardly from from an inner hub end of the blade (1) to 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 thick zone (TZ), in which the airflow correction arrangement (2, 3) comprises a spoiler (3) comprised to increase the elevation of the blade and an apex generator (2) disposed between an anterior edge (12) and the rear edge (13) and understood to maintain a connected air flow (42) between the apex 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) to correct airflow over the pressure side (11) of a wind turbine rotor blade (1) for a blade region (1) which has a thickness coefficient of at least 0.45.
