A rotor blade for a wind power installation, which extends in a longitudinal direction with a profile course from a blade connector to a blade tip, wherein the profile course contains at least one profile, comprising: a suction side and a pressure side, a relative profile thickness of greater than 25%, a profile chord, which extends between a leading edge and a trailing edge of the profile and has a length which defines the profile depth, a mean line which extends at least partially below the profile chord, a convex region which extends on the suction side from the trailing edge, and a convex region which extends on the pressure side from the trailing edge, wherein the convex region on the pressure side defines a rounded transition region of the pressure side to the trailing edge.

Rotor blade for a wind power installation, wind power installation, and method for designing a rotor blade

A rotor blade for a rotor, in particular of a wind power installation, having a rotor-blade length constituted between a root region and a rotor-blade tip, a rotor-blade depth constituted between a leading edge and a blunt trailing edge, a rotor-blade thickness constituted between a pressure side and a suction side, a suction-side trailing-edge region extending on the suction side and/or a pressure-side trailing-edge region extending on the pressure side, the suction-side trailing-edge region and/or the pressure-side trailing-edge region extending from the blunt trailing edge in the direction of the leading edge with an extent of less than 30%, in particular less than 20%, of the chord, and the suction-side trailing-edge region and/or the pressure-side trailing-edge region having at least one eddy generator.
