Abstract
The present invention is related to a rotor blade for a wind energy plant, with a blade root, with a first longitudinal portion starting from the blade root, with a second longitudinal portion, following up the first longitudinal portion and running into a blade tip, with a first surface, facing a tower of the wind energy plant in its assembled state, and a second surface, facing away from the tower of the wind energy plant in its assembled state, wherein an imaginary reference plane is spanned up by a rotation, taking place in the operation of the rotor blade, of the longitudinal axis of the first longitudinal portion around the rotational axis of a rotor of the wind energy plant carrying the rotor blade which prevents collisions of the blade tip with the tower of the wind energy plant.
