Patent ID: 10968885

Abstract:
A rotor blade having a suction side and a pressure side for a wind power installation, comprising: a rotor blade root of a hub region for the attachment of the rotor blade to a rotor hub, and a rotor blade tip arranged toward that side of a tip region which is averted from the rotor blade root. In the region of the hub region, the rotor blade has, at least in part, a thickness profile which has a thorn-like extension at its trailing edge, wherein, in the region of the hub region, the thickness profile has, at least in part, a first thorn-like extension at the trailing edge at the suction side, and a second thorn-like extension at the trailing edge at the pressure side, and, in the region of the hub region, the thickness profile has, at least in part, a flow stabilizer and/or a vortex generator on the suction and/or pressure side.
