Abstract (en)

[origin: WO2006029593A1] The invention relates to a wind turbine comprising a tower (10), a nacelle (14) that is mounted on the tower (10) and can be rotated about the axis of the latter and a rotor (16), which is carried by the nacelle (14) on the lee side and comprises at least one rotor blade (18). The flexural strength of the rotor blade or blades (18) permits the elastic flexure of said blade by more than half of its extension.
