Abstract

A two-part or multi-part rotor blade and also to a method which is associated with it. The rotor blade is split into at least one rotor blade component which is close to the hub and one rotor blade component which is remote from the hub at a separation point in the longitudinal direction, wherein the rotor blade component which is close to the hub and the rotor blade component which is remote from the hub can be connected at the separation point for operation of the wind turbine. A ratio of profile thickness to profile depth, called relative thickness, at the separation point lies within a range of from 0.4 to 0.5. An improved two-part or multi-part rotor blade in spite of the unexpectedly high relative thicknesses.
