Abstract
A wind turbine rotor blade is provided with a rotor blade root region, a rotor blade tip region, a pressure side, a suction side, a leading edge, a trailing edge and at least one flange along a longitudinal direction of the rotor blade. Furthermore, a deflecting unit is provided between one end of the at least one flange and the rotor blade tip region. At least one air scoop is provided on the flange, wherein the air scoop protrudes in a region between a first and second flange.
Claims8
A wind turbine rotor blade, comprising:
- a rotor blade root region,
- a rotor blade tip region,
- a pressure side,
- a suction side,
- a leading edge,
- a trailing edge,
- first and second flanges extending between the pressure side and the suction side and along a longitudinal direction of the rotor blade,
- a deflector between the rotor blade tip region and ends of the first and second flanges, wherein the deflector is configured to deflect heated air flowing from the rotor blade root region along the first and second flanges,
- at least one air scoop on one of the first or second flanges, and
- a boundary-layer extraction unit that adjoins ends of the first and second flanges at the rotor blade tip region, wherein the boundary-layer extraction unit is configured to extract a turbulent boundary layer or openings of an air flow.
