Abstract
A wind turbine rotor blade is for mounting on a rotor hub covered by a spinner having a rotor blade opening and includes a wind turbine rotor blade body having a fastening section and a longitudinal section. The fastening section is configured for fastening the rotor blade body on the rotor hub. The longitudinal section is arranged inside the rotor blade opening when the wind turbine rotor blade is mounted on the rotor hub. The longitudinal section and the rotor blade opening conjointly define an annular gap therebetween when the wind turbine rotor blade is mounted on the rotor hub. A cover profile is fastened on the wind turbine rotor blade and covers the annular gap. The cover profile has a circular ring-shaped outer edge and a circular ring-shaped inner edge. The inner edge is disposed at a radial distance from the wind turbine rotor blade. An annular-shaped cover element is fastened on the wind turbine rotor blade and bridges the radial distance.
