Abstract
A rotor blade for a wind turbine, comprising a rotor blade root for fixing the rotor blade to the hub of a wind turbine, an inner blade portion which extends from the rotor blade root in the direction of a longitudinal extension of the rotor blade, and a rear edge segment for increasing the depth of the rotor blade in the profile depth direction in the region of the inner blade portion, wherein the rear edge segment is fixed to the inner blade portion and has an edge facing the inner blade portion. A cover lip is proposed which overlaps with the edge and is arranged in a transition region from the inner blade portion to the edge of the rear edge segment.

A rotor blade for a wind turbine, comprising:
- a rotor blade root for fixing the rotor blade to a hub of the wind turbine;
- an inner blade portion extending from the rotor blade root in a direction of a longitudinal extension of the rotor blade;
- a rear edge segment that increases a depth of the rotor blade in a profile depth direction in a region of the inner blade portion, wherein the rear edge segment is coupled to the inner blade portion and has an edge facing the inner blade portion;
- and
- a cover lip adapted to a contour of the edge of the rear edge segment and overlapping the edge and a transition region defined by an outer surface gap between an outer surface of the inner blade portion and an outer surface of the edge of the rear edge segment, such that the cover lip closes the outer surface gap and allows the inner blade portion to move relative to the rear edge segment,
- wherein the cover lip has a main portion and a pocket, wherein the cover lip overlaps the outer surface of the inner blade portion and the outer surface of the edge of the rear edge segment to cover the outer surface gap, and
- wherein the pocket has a depth, and wherein the edge of the rear edge segment is received movably along the depth of the pocket.
A rotor blade for a wind turbine, comprising:
- a rotor blade root for fixing the rotor blade to a hub of the wind turbine;
- an inner blade portion extending from the rotor blade root in a direction of a longitudinal extension of the rotor blade;
- a rear edge segment that increases a depth of the rotor blade in a profile depth direction in a region of the inner blade portion, wherein the rear edge segment is coupled to the inner blade portion and has an edge facing the inner blade portion;
- and
- a cover lip overlapping the edge and arranged in a transition region from the inner blade portion to the edge of the rear edge segment,
- wherein the cover lip has a pocket with a depth, wherein the edge of the rear edge segment is received movably along the depth of the pocket,
- wherein the pocket has one or more anti-friction members with an anti-friction surface for slidingly receiving the edge of the rear edge segment,
- wherein the anti-friction surface is made of a thermoplastic plastic, and
- wherein a fabric laminate is arranged on a side of the anti-friction member facing away from the anti-friction surface.
A rotor blade for a wind turbine, comprising:
- a rotor blade root for fixing the rotor blade to a hub of the wind turbine;
- an inner blade portion extending from the rotor blade root in a direction of a longitudinal extension of the rotor blade;
- a rear edge segment that increases a depth of the rotor blade in a profile depth direction in a region of the inner blade portion, wherein the rear edge segment is coupled to the inner blade portion and has an edge facing the inner blade portion;
- and
- a cover lip adapted to a contour of the edge of the rear edge segment and overlapping the edge and a transition region defined by a surface gap between an outer surface of the inner blade portion and the edge of the rear edge segment, such that the cover lip closes the surface gap and allows the inner blade portion to move relative to the rear edge segment, wherein the cover lip has a base member, wherein the base member has a first end and a second end, wherein a the pocket is arranged at the first end, and wherein an attachment portion for attachment to the inner blade portion is arranged at the second end opposite the pocket
- and
- wherein a seal having a sealing profile is arranged on the attachment portion.
