Abstract

A trailing-edge segment of a wind-turbine rotor blade for increasing a profile depth of the rotor blade of a wind turbine. The trailing-edge segment of a wind-turbine rotor blade comprises at least one inner blade segment, having an inner blade shell, at least one middle blade segment, having a middle blade shell. In this case, the at least one middle blade segment and the at least one inner blade segment can be coupled to each other via a coupling means, and the coupling means has at least one shell element, having two inner sides that are parallel to each other and form a receiving space, designed to receive at least one of the inner blade shell or middle blade shell, and the two inner sides each being realized such that they can be connected to at least one of the inner blade shell or middle blade shell, in such a manner that a force acting upon the trailing-edge segment of a wind-turbine rotor blade is introduced centrically into the coupling means.
