Abstract
A blade adapter for rotor blades of wind turbines, for increasing the rotor diameter, has a first end for attaching to the rotor hub, and a second end, spaced apart in the axial direction, for connecting to the blade root of a rotor blade. In addition, the blade adapter, at its first and second end, has a pitch circle for connecting to the rotor hub or to the rotor blade, wherein the wall of the blade adapter extending in the axial direction is open outwardly, in the form of a truncated cone, from the first end toward the second end, in at least one portion.
