| 摘要 |
The invention relates to a rotor blade (20) of a wind turbine (10), wherein the rotor blade (20) comprises a lift modifying device (30). The lift modifying device (30) is a part of the trailing edge section (23) of the rotor blade (20). The lift modifying device (30) is configured such that, at a predetermined loading (31, 32) of the trailing edge section (23), an air channel (46) opens up a flow path from the pressure side (251) to the suction side (252) and vice versa in the trailing edge section (23). As a consequence, airflow (45) flowing from the leading edge section (24) of the rotor blade (20) to the trailing edge section (23) is at least partly deflected by the open air channel (46), which results in a modification of the lift of the rotor blade (20). The invention furthermore relates to a method to modify the lift of a rotor blade (20) of a wind turbine (10). |
