ABSTRACT:
The rotor blade for a wind energy turbine comprising a longitudinal shell defining a root to be connected to a hub of a rotor, a tip, a forward edge and a rearward edge, the shell having a spar including two spar caps connected via at least one shear web arranged between the forward and rearward edges of the shell and extending in the longitudinal direction of the shell, and a structural damping system arranged within the shell and having a pendulum including a dumped sandwich beam and a mass element located at one end of the beam. The beam comprises a sandwich structure including at least three layers comprising at least one damping middle layer arranged between and connected to outer layers of an elastic material. The sandwich beam is connected to the at least one shear web in a cantilevered manner such that the mass element is proximal to the tip of the shell and the beam can be oscillated in a direction towards and away from the forward and rearward edges of the shell.
