Abstract
Wind turbine rotor blade with a longitudinal axis, a blade tip, a blade root, a leading edge, a trailing edge and a cross-section arranged orthogonally to the longitudinal axis and changing from the blade root to the blade tip, is the cross-section being formed at the blade root and in the middle of the rotor blade by an aerodynamic profile, and an imaginary reference plane arranged with respect to the rotor blade which includes the longitudinal axis of the rotor blade, wherein, in a cross-section, an angle αis defined between the reference plane and a straight line, which connects the longitudinal axis with the trailing edge, and describes the position of the trailing edge, wherein the angle αincreases with decreasing distance from the blade root in a first longitudinal portion of the rotor blade and decreases with decreasing distance from the blade root in a second longitudinal portion.
