Abstract
A rotor blade for a wind turbine, a wind turbine, a wind park and a method for configuring a rotor blade which is divided in two. A rotor blade for a wind turbine, which rotor blade extends in the longitudinal direction from a blade connection to a blade tip with a variable profile depth, wherein the rotor blade is divided at a separating point and has a separating point profile depth at the separating point, a relative blade length of the rotor blade, starting from the blade connection, is defined in a blade length value range between 0% to 100%, the separating point is arranged in a blade length value range between 25% and 50%, a rotor blade section facing the blade connection and a rotor blade section facing away from the blade connection can be connected at this separating point for correct operation of the rotor blade, a depth ratio which is composed of the variable profile depth and the separating point profile depth is defined, a development index is defined as a gradient of the depth ratio in the direction of the relative blade length, and the development index in the region of the separating point is less than 1.
