1. A wind turbine rotor blade, comprising:
an elongate blade base body the elongate base body transitions to a circular blade root with a circular face side; and a plurality of connecting elements disposed in the circular blade root, each of the plurality of connecting elements comprising:
an axially extending connecting portion configured to be connected with corresponding connecting portions of a rotor hub of a wind turbine,a circumferentially extending protrusion, anda corresponding circumferentially extending recess, wherein adjacently disposed connecting elements of the plurality of connecting elements are interconnected via the circumferentially extending protrusion of a first of the adjacently disposed connecting elements and the corresponding circumferentially extending recess of a second of the adjacently disposed connecting elements, each of the interconnections being mechanically stable in a radial direction and in a circumferential direction, and wherein a mechanical stiffening occurs in the blade root via the interconnection of the plurality of connecting elements into a closed ring-shaped arrangement. |
