A flexible aeroshell extender piece for an inboard part of a wind turbine blade is described, along with an associated method of manufacture. The flexible aeroshell is formed by first assembling a consolidated aeroshell piece, and then making a series of slits at the trailing edge of the aeroshell piece. Such a construction provides an aeroshell having a relatively flexible trailing edge section, which allows for bending or flexing of the aeroshell trailing edge during wind turbine blade operation.

A method and mould system for manufacturing at least a root section of a wind turbine blade is described. The method and system utilise a mould inlay which is arranged on top of a mould surface of a mould part so as to change the radius of curvature of the mould part and thereby also the diameter of a root section manufactured via the mould part and mould inlay. Further, blades manufactured via the method and mould system are described.

Method of manufacturing a wind turbine blade

A component for a wind turbine blade is described having a reinforced through-going aperture. The reinforcement can be provide by way of a fibre rope arranged around the periphery of the aperture, or as fibre material arranged in a radially-extending arrangement from the aperture.

A wind turbine blade assembly comprising a wind turbine blade having a tip end and a root end, and a leading edge and a trailing edge with a chord length extending therebetween is described. The wind turbine blade assembly further comprises an aeroshell extender piece comprising a body for attachment to a trailing edge side of a profile of a wind turbine blade, the body having a first end for attachment to the trailing edge side of the profile, and a second trailing edge end to form an extended airfoil trailing edge profile for a portion of the profile of the wind turbine blade. The aeroshell extender piece is attached to the wind turbine blade at least partly using at least one profile wedge, said at least one profile wedge being shaped to compensate for the geometry of the wind turbine blade.

A blade () for a rotor of a wind turbine () is disclosed. The blade is assembled from an inboard blade part () closest to the hub and an outboard blade part () farthest from the hub of the wind turbine. The inboard part () comprises a load carrying structure () with a first aerodynamic shell () fitted to the load carrying structure (), and the outboard part () comprises a blade shell () with a load carrying structure () integrated in the blade shell ().

A wind turbine blade comprises a profiled contour having a pressure side and a suction side, a leading edge and a trailing edge with a chord extending between the leading edge and the trailing edge. The profiled contour generating a lift when being impacted by an incident airflow is formed by a hollow shell body. The hollow shell body is formed by at least a first shell body part and a second shell body part, which are mutually connected at least at the trailing edge and/or the leading edge. An edge stiffener is arranged within the hollow shell body at a first part of the edges, a first surface part of the edge stiffener being connected to an inner side of the first shell body part, and a second surface part of the edge stiffener being connected to an inner side of the second shell body part.
