| 摘要 |
The invention relates to a wind turbine rotor blade (200) comprising a first rotor blade section (201) and a second rotor blade section (202). The first and second rotor blade sections (201, 202) form a total length (L) of the rotor blade (200), and the first rotor blade section (201) and the second rotor blade section (202) can be moved relative to each other by a centrifugal force acting along a longitudinal axis (214) of the rotor blade (200) when the rotor blade (200) rotates, such that the total length (L) of the rotor blade (200) is variable. |
