Wind turbine rotor blade

A wind turbine rotor blade (1) having a top side (13), a bottom side (14), a leading edge (16), a trailing edge (15), a hub fastening means (17) and a blade tip (12) wherein the wind turbine rotor blade (1) has a hub region (111), a center region (112), and a blade tip region (113), and wherein a root region (11) is defined from the hub fastening means (17) to the maximum blade depth (Smax), wherein

• an air-conducting channel (23) is provided inside the wind turbine rotor blade (1) extending radially outward for conducting suctioned air from a suction region (21) to a blow-out region (22) arranged in the blade tip region (113), and a boundary layer suctioning occurs in a suction area (21) where a suctioning of the air from the top side (13) of the wind turbine rotor blade (1) occurs,
• a boundary layer fence (28) is provided in the hub region (111) near the hub fastening means (17) in order to prevent a flow in the direction of the hub fastening means (17),
• the trailing edge (15) in the hub region (111) and at least in the first section of the central region (112) connected thereto is blunt, wide and/or cut off running in the direction of the blade tip region (113), wherein this continues in the root region (11) towards the direction of the blade tip (12),
• the suction area (21) is arranged in the area in which a laminar air flow detaches from the top side (13) based on the rotor blade geometry, so that an attachment and continuation of laminar air flow along the top side (13) occurs, and
• the suction area (21) starting at or near the boundary layer fence (28) in the hub area (111) extends into the central region (112), wherein the suction area (21) extends over the root region (11) in the direction of the blade tip (12) in the center region (112).
