Abstract
The invention relates to a rotor blade () of a wind energy plant with a top side (suction side) and a bottom side (pressure side) wherein profiles () with a front edge and a back edge () 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 () is predetermined for each profile () and the profiles () in the outer area facing the rotor blade tip are designed with a relative thickness of less than 30%. The rotor blade () is characterized in that an attached device (), which has an attached-device inflow surface as well as a start point () facing the front edge of the attached-device inflow surface () and an end point facing the back edge () of the attached-device inflow surface (), is arranged along the longitudinal axis in the inner area dedicated to the rotor blade root to profiles () with a relative thickness of more than 30% on the pressure side.
