Abstract

The disclosure concerns a segmented wind turbine rotor blade, which is formed by at least two rotor blade segments, wherein at a division area of the wind turbine rotor blade the segments are firmly connected together at respective connection ends via a plurality of connecting elements, wherein a gap is formed between the connection ends, and a fairing is attached to the segments at the division area, the fairing covering the gap and the connecting elements; wherein the fairing is divided into at least two separate fairing sections, the fairing sections are coupled together at coupling regions at the pressure side and/or at the suction side of the rotor blade, and the coupling regions are spaced apart from the trailing edge or leading edge. The disclosure also concerns a method.
