Abstract

The invention relates to a wind turbine (100). The wind turbine (100) comprises a rotor blade (10). The rotor blade (10) comprises a first winglet (13) provided to the rotor blade (10) in the vicinity of the first end (15) of the rotor blade (10) or in the first end (15) of the rotor blade (10). The rotor blade is arranged to be rotated around an axis of rotation (R). The invention further relates to a rotor blade (10).
