The invention relates to a rotor blade (60) of a wind energy plant with a top side (suction side) and a bottom side (pressure side) wherein profiles (21, 22, 23, 24, 25) with a front edge and a back edge (62) in cross-section are designed along a longitudinal axis between a rotor blade root and a ro
The invention relates to a rotor blade (60) of a wind energy plant with a top side (suction side) and a bottom side (pressure side) wherein profiles (21, 22, 23, 24, 25) with a front edge and a back edge (62) in cross-section are designed along a longitudinal axis between a rotor blade root and a rotor blade tip, one designed-based direction of air inflow (31, 32, 33, 34, 35) is predetermined for each profile (21, 22, 23, 24, 25) and the profiles (21, 22, 23, 24, 25) in the outer area facing the rotor blade tip are designed with a relative thickness of less than 30%. The rotor blade (60) is characterized in that an attached device (51), which has an attached-device inflow surface as well as a start point (41, 42, 43) facing the front edge of the attached-device inflow surface (52) and an end point facing the back edge (62) of the attached-device inflow surface (52), is arranged along the longitudinal axis in the inner area dedicated to the rotor blade root to profiles (21, 22, 23, 24, 25) with a relative thickness of more than 30% on the pressure side.
