ABSTRACT:
The present invention concerns a rotor blade for a wind power plant having an aerodynamic profile. A rotor blade for the wind power plant has an aerodynamic profile having a pressure side and a suction side. A wind power plant rotor blade tip is curved in a direction of the pressure side of the rotor blade so as to form an edge arc. The wind power plant rotor blade tip narrows towards an edge arc upper edge and has an edge arc leading edge and an edge arc trailing edge. The edge arc leading edge and the edge arc trailing edge extend equally in a predetermined, curved gradient to the edge arc upper edge.
