Provided is a method for connecting two wind turbine blade portions, the method including the steps of: a) providing) a first wind turbine blade portion and a second wind turbine blade portion, b) providing a plurality of first markers on the first blade portion and providing a plurality of second markers on the second blade portion, c) determining of target positions of the first markers and the second markers, d) aligning the wind turbine blade portions to each other and comparing actual positions of the first markers and the second markers with the target positions, and e) connecting the wind turbine blade portions together. Therefore, a shape accuracy of a wind turbine blade can be improved.

Method for connecting two wind turbine blade portions, method for producing a wind turbine, and method for connecting two molded portions

Provided is a method for producing a wind turbine blade having a blade body including a body part and a tip part, the blade being produced by using a mold, wherein a prefabricated tip part having a first connection interface is arranged adjacent to the mold for producing the body part, whereby building elements for building the body part are arranged in the mold providing a second connection interface which corresponds to and connects to the first connection interface, whereafter both connection interfaces are fixed by applying a fixing agent and curing it.

Method for producing a wind turbine blade

Provided is a mold adapted for producing at least a part of a wind turbine blade, including a support and shell fixed to the support for accommodating blade building elements to be embedded in a resin matrix, wherein the shell includes at least one main body shell element and several diverse tip shell elements, which are exchangeably fixable to the support.

Mold adapted for producing at least a part of a wind turbine blade

Provided is a mold adapted for producing a wind turbine blade, including a first carrier and a shell for accommodating blade building elements to be embedded in a resin matrix for building a blade body part, which shell is placed on the first carrier, and a second carrier changeable in its length and elongating the first carrier adapted to accommodate a prefabricated blade tip to be connected to the blade body part when the blade body part is built.

A method for assembling blade parts of a wind turbine blade includes the steps of: obtaining information about a connection area of a blade part, at least one of selecting, customizing and manufacturing an adaptor piece depending on the obtained information about the connection area of the blade part, wherein the adaptor piece serves to connect the blade part with at least another blade part, and connecting the blade part to the adaptor piece. Independently manufactured blade parts of a wind turbine blade are assembled in a manner such that the assembled blade comes as close as possible to a single-casted blade.

Method and a system for assembling blade parts of a wind turbine blade

Provided is a beam for a wind turbine blade of a wind turbine, whereby the beam is made from a composite material including a matrix and a reinforcement, the beam having a length in a longitudinal direction of the beam, a width in a width direction of the beam and a thickness in a thickness direction of the beam. The beam includes at least one longitudinal recess arranged in the longitudinal direction of the beam, whereby the at least one longitudinal recess separates the beam into adjacent longitudinal beam portions, whereby the longitudinal recess has the width or the thickness of the beam.

Beam for a wind turbine blade, wind turbine blade, wind turbine and method for manufacturing a beam for a wind turbine blade

Provided is a beam for a wind turbine blade of a wind turbine, whereby the beam is made from a composite material including a matrix and a reinforcement. The beam includes at least one recessed longitudinal end section in which the beam includes at least one longitudinal recess arranged in a longitudinal direction or substantially a longitudinal direction of the beam extending from a longitudinal mid-section of the beam to a longitudinal end of the beam, so that the at least one longitudinal recess separates the beam into adjacent longitudinal beam portions, whereby the longitudinal beam portions are attached to the longitudinal mid-section.

Beam for a wind turbine blade, wind turbine blade, wind turbine, method for manufacturing a beam for a wind turbine blade and method for manufacturing a wind turbine blade

Provided is a wind turbine blade for a wind turbine, the wind turbine blade including a root, a tip, a trailing edge, a leading edge and at least two beams including carbon fiber-reinforced plastic and being spaced apart from one another, wherein the at least two beams are arranged in the wind turbine blade in the longitudinal direction of the wind turbine blade at the trailing edge or within a distance of 25% of the width from the trailing edge, whereby the at least two beams are electrically connected to one another by at least one electrically conductive member and at least one of the at least two beams and/or at least one of the at least one electrically conductive member is configured to be connected to a down conductor of the wind turbine.
