A rotor blade for a wind power installation with a longitudinal direction in which the rotor blade extends, at least one first rotor blade segment with a first end face, and at least one second rotor blade segment with a second end face, wherein the first rotor blade segment is coupled on the end face in the longitudinal direction to the second rotor blade segment, wherein the first and second rotor blade segments each comprise: a blade laminate with a plurality of laminate layers which are arranged stacked in a profile thickness direction, and arranged on the end face, a plurality of mounting elements for coupling the first rotor blade segment to the second rotor blade segment, wherein each of the mounting elements extends in the longitudinal direction and has two contact faces which are arranged transversely, in particular orthogonally to the longitudinal direction at a distance from one another which diminishes in non-linear fashion towards the end.

Rotor blade for a wind turbine, rotor blade segment, wind turbine, and method for producing a rotor blade

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.

Wind turbine and rotor blade for a wind turbine

There is provided a method of installing a wind turbine rotor blade. A holding unit is releasably fixed at the exterior to the rotor blade without intervention in the surface of the rotor blade. A holding cable is fixed to the holding unit. The rotor blade is installed on the hub of the wind turbine, for which purpose the rotor blade is pulled up for example by means of a crane. The holding unit is released by changing the pitch of the rotor blade.

Method for installing a wind turbine rotor blade

A trailing-edge segment of a wind-turbine rotor blade for increasing a profile depth of the rotor blade of a wind turbine. The trailing-edge segment of a wind-turbine rotor blade comprises at least one inner blade segment, having an inner blade shell, at least one middle blade segment, having a middle blade shell. In this case, the at least one middle blade segment and the at least one inner blade segment can be coupled to each other via a coupling means, and the coupling means has at least one shell element, having two inner sides that are parallel to each other and form a receiving space, designed to receive at least one of the inner blade shell or middle blade shell, and the two inner sides each being realized such that they can be connected to at least one of the inner blade shell or middle blade shell, in such a manner that a force acting upon the trailing-edge segment of a wind-turbine rotor blade is introduced centrically into the coupling means.

Wind turbine rotor blade trailing edge segment

A rotor blade of a wind turbine. The rotor blade comprises at least one rotor-blade inner portion, having a region connecting to the rotor-blade hub, and at least one rotor-blade outer portion, having a rotor-blade tip, the rotor-blade inner portion and the rotor-blade outer portion each being made substantially of a fibre-reinforced plastic, and the rotor-blade inner portion and the rotor-blade outer portion being connected to each other by a connecting device. The connecting device in this case comprises an inner insert that is at least partially wrapped in the fibre-reinforced plastic of the rotor-blade inner portion, an outer insert that is at least partially incorporated in the fibre-reinforced plastic of the rotor-blade outer portion, the inner insert and the outer insert being connected to each other via a connecting element.

Wind turbine rotor blade

The invention concerns a rear box section for a rotor blade, in particular of a wind power installation, comprising a pressure-side surface, a suction-side surface, a trailing edge separating the pressure-side and suction-side surfaces, and a connecting side which is opposite to the trailing edge and which is adapted for mounting to a corresponding connecting surface of the rotor blade. The invention concerns in particular a rear box section which is sub-divided into a foot segment having the connecting side and one or more head segments which have the trailing edge and which can be coupled to the foot segment. The invention also concerns a rotor blade for a wind power installation, and a wind power installation.
