Abstract
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.
