Abstract

The invention is related to an elastic torsion element 5d for connecting a rotor blade to a rotor hub of a rotor, the elastic torsion element 5d comprising at least two elastically deformable plates 11a, wherein each one of the at least two elastically deformable plates 11a comprises fiber reinforced polymers, wherein respective fibers of the fiber reinforced polymers of each one of the at least two elastically deformable plates 11a are at least arranged along one of a first and a second dominant fiber directions 12a, 12b, wherein the first dominant fiber direction 12a crosses the second dominant fiber direction 12b in a predetermined fiber direction crossing region 14, and wherein the elastic torsion element 5d comprises an integrated elastic lead-lag hinge 4 that is formed at the predetermined fiber direction crossing region 14.
