The disclosure concerns a wind turbine, comprising: a hub with a hollow cylindrical region with a mean circumference U; at least one rotor blade mounted rotatably on the hub, with a blade laminate which extends in the longitudinal direction of the rotor blade and at least in portions forms a hollow cylinder with a mean circumference U; and at least one blade bearing for mounting the rotor blade on the hub, with a first bearing ring which is arranged on the hub side and connected by means of a first flange connection to a rotor hub flange formed on a rotor-blade side end portion of the hub, wherein the first flange connection has at least one hub longitudinal bolt which is arranged on a circumference Ucoaxially to the blade bearing; and a second bearing ring which is arranged on the rotor blade side and connected by means of a second flange connection to a rotor blade flange formed on a hub-side end portion of the rotor blade, wherein the second flange connection has at least one rotor blade longitudinal bolt which is arranged on a circumference Ucoaxially to the blade bearing. The disclosure achieves the fundamental object in that a first radial offset Vis formed between the circumference Uand the circumference U, and/or a second radial offset Vis formed between the circumference Uand the circumference U. In a further aspect, the disclosure achieves the fundamental object with a wind turbine rotor blade and a rotor blade bearing.

Wind turbine, wind turbine rotor blade, and blade bearing for a wind turbine

A method for testing a rotor blade component of a rotor blade for a wind power installation, comprising: dividing a rotor blade component of a rotor blade for a wind power installation into two, three or more rotor blade component segments, forming cutouts in a connection interface at a connection end of one of the rotor blade component segments. A rotor blade component segment of a rotor blade for a wind power installation, the rotor blade component segment comprising a connection end which has been formed by dividing a rotor blade component of a rotor blade for a wind power installation into two, three or more rotor blade component segments, a connection interface at the connection end of the rotor blade component segment, and cutouts which are formed in the connection interface and serve for connection of the rotor blade component segment to a test stand.

Method for testing a rotor blade component of a rotor blade for a wind power installation, and rotor blade component

A wind turbine including a rotor blade hub, a generator, and a magnetic transmission which is connected at the drive side to the rotor blade hub and at the driven side to the generator. The magnetic transmission is in the form of a multi-stage, in particular two-stage, magnetic transmission.

Wind turbine having a multi-stage magnetic transmission

A method of producing a wind turbine rotor blade. The wind turbine rotor blade has at least an inner blade portion and an outer blade portion, as well as a connecting element. The inner blade portion is wound on a winding form having a first and a second winding portion. The first and second winding portions are releasably fixed to each other by way of a screw connection. The second winding portion is of a conical configuration so that after winding of the inner blade portion a sleeve is produced at an end of the inner blade portion.

Method for producing a wind turbine rotor blade, and wind turbine rotor blade

There is provided a wind turbine rotor blade having a blade outer side, a wall with a laminate, a blade inner side and at least a first and a second rotor blade part. The at least one first and second rotor blade parts are fixed together by means of at least one connecting unit in a separation plane. The connecting unit has at least one cable with a first end with cable fibers which are fixed in or at the laminate of the wall. The connecting unit has at least one projection at the first and second rotor blade parts respectively. The projections are respectively fixedly connected to the wall of rotor blade. The at least one cable is connected at at least one projection. The connecting unit has at least one tensioning element, by means of which the projections on the first and second rotor blade parts can be braced with each other.

Wind turbine rotor blade and wind turbine

A tower segment of a tower of a wind turbine, a tower portion of a wind turbine, a tower of a wind turbine, a wind turbine, a method of producing a tower segment of a wind turbine and a method of connecting tower segments of a wind turbine. The tower segment includes a compression element and a tension element, wherein the tension element is arranged with its main direction of extent substantially horizontally in the installation state and is spaced from the tower segment in a direction in orthogonal relationship with its main direction of extent and is connected to the compression element by way of an intermediate element.
