Abstract

A rotor blade for a wind turbine, to a wind turbine having a tower, a nacelle and a rotor, and also to a wind farm. The rotor blade comprises an inner blade portion which extends in the longitudinal direction of the rotor blade starting from a rotor blade root, and a trailing edge segment which is arranged on the inner blade portion and intended for increasing the profile depth of the rotor blade along a portion in the rotor blade longitudinal direction. The rotor blade has a pressure-side surface and a suction-side surface which are each formed in certain regions from parts of the inner blade portion and of the trailing edge segment. At least one slot-like air inlet and/or air outlet which extends substantially in the rotor blade longitudinal direction is formed on the pressure-side and/or suction-side surface of the rotor blade in the region of the trailing edge segment. The rotor blade achieves a more efficient influence on the boundary layer.
