Wind turbine blade, wind turbine and method for operating a wind turbine

Abstract

A wind turbine blade (10, 10′) includes a shell (11) and a torque transferring member (20) at least partly arranged inside the shell (11). The shell (11) includes a root portion (12) and defines a longitudinal direction (r11). The torque transferring member (20) includes a root section (21) and a longitudinal axis (r20) at least substantially parallel oriented to the longitudinal direction (r11). The root section (21) of the torque transferring member (20) is rotatably around the longitudinal axis (r20) with respect to the root portion (12) of the shell (11). The torque transferring member (20) is mechanically connected via a coupling (26) with the shell (11) for providing a torsional moment (ΔT1-ΔT3) on the shell (11).
