A wind turbine rotor blade element includes a connection section with a front face, an inner and an outer surface. A plurality of connection assemblies each have (i) a metal insert with a longitudinal axis, a circumferential outer surface and a joining portion for connecting the rotor blade to a wind turbine rotor hub; and, (ii) a transition material aligned with the metal insert and having a tapering longitudinal section. The longitudinal section has an axial outer surface parallel to the longitudinal axis of the metal insert and an inclined outer surface at an angle with reference to the longitudinal axis. The connection assemblies are embedded in the connection section such that the joining portions of the metal inserts are accessible. The connection assemblies are arranged in an inner row closer to the inner surface of the connection section and an outer row closer to the outer surface thereof.

Wind turbine rotor blade element having connection assemblies

The invention is directed to a partitioned rotor blade for a wind turbine, which, with respect to a longitudinal axis of the rotor blade, is formed by a first rotor blade segment and a second rotor blade segment. The first rotor blade segment has at a first connection end, a first connecting region along the longitudinal axis, and the second rotor blade segment has at a second connection end, which is associated with the first connection end, a second connecting region along the longitudinal axis. The two connecting regions are connected at a partition interface of the rotor blade and form a common segmentation region. In the segmentation region, a common outer contour of the rotor blade is formed by the connection of both rotor blade segments. The outer contour is singly curved.
