Patent number: 11466665Abstract: 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.Type: GrantFiled: October 22, 2019Date of Patent: October 11, 2022Assignee: Wobben Properties GmbHInventor: Falk Spieth

Publication number: 20200072186Abstract: A rotor blade for a wind turbine, to a wind turbine having a tower, a nacelle and a rotor, and also to a wind farm. The rotor blade comprises an inner blade portion which extends in the longitudinal direction of the rotor blade starting from a rotor blade root, and a trailing edge segment which is arranged on the inner blade portion and intended for increasing the profile depth of the rotor blade along a portion in the rotor blade longitudinal direction. The rotor blade has a pressure-side surface and a suction-side surface which are each formed in certain regions from parts of the inner blade portion and of the trailing edge segment. At least one slot-like air inlet and/or air outlet which extends substantially in the rotor blade longitudinal direction is formed on the pressure-side and/or suction-side surface of the rotor blade in the region of the trailing edge segment. The rotor blade achieves a more efficient influence on the boundary layer.Type: ApplicationFiled: September 18, 2017Publication date: March 5, 2020Inventors: Marcel KRUSE, Falk SPIETH

Patent number: 10473085Abstract: 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.Type: GrantFiled: July 8, 2015Date of Patent: November 12, 2019Assignee: Wobben Properties GmbHInventors: Falk Spieth, Florian Rubner, Christoph Wenk
