Also, a leading edge fairing for attachment to a blade body of a wind turbine blade; a method of fitting a leading edge fairing to a wind turbine blade; and a kit of parts with a number of the leading edge fairings.

A lightning protection system for the joint of a modular blade. The joint comprises a number of coated metal elements by Xpacer equipotentially bonded with a number of stacks disposed at the sides of the upper cap and the lower cap and with the lightning down-drop. The preforms of the joint include two stacks at the leading edge and another two stacks at the trailing edge. The stacks are formed by layers of carbon fibre and layers of glass fibre, replaced by copper mesh as from the equipotentiation line. The stack incorporates at the side thereof a metal strip joined to the metal strip that links the tip cap and the root cap, and is coated with a layer of glass fibre.

A jointed wind turbine rotor blade includes a first blade segment and a second blade segment. A chord-wise joint separates the first and second blade segments, wherein internal joint structure joins the first and second blade segments across the chord-wise joint. A first heating system is configured within the first blade segment, and a second heating system is configured within the second blade segment. A disconnectable coupling is configured between the first and second blade segments at the chord-wise joint to supply power or a fluid medium from the first blade segment across the chord-wise joint for use by the second heating system in the second blade segment.

A turbine blade and a method of manufacturing the wind turbine, wherein the wind turbine blade comprises a composite structure and a surrounding layer. The composite structure comprises a stack of pultruded elements where an infusion-promoting layer is arranged between adjacent pairs of pultruded elements (18). The infusion-promoting layers have a higher permeability than the surrounding layer so that the resin flows at a higher speed within the stacked structure than in the surrounding layer.

A fairing for a modular blade of a wind turbine generator, comprising including a joining zone disposed between two consecutive modules of the modular blade. The fairing is comprised of different components; the suction side fairing, the pressure side fairing and auxiliary components, such as tabs to facilitate the joining of the components. The leading edge fairing and the trailing edge fairing are constituted of an elastomeric material, preferably silicone, supported in a rigid glass fibre framework in order to absorb the warping experienced by the blade during the operation thereof. The attachment elements employed to join the fairings together and to the setbacks of the blade shell are rivets or similar. All the fairings incorporate the metal elements necessary to be equipotentially bonded, being linked to the lighting down-drop.

The present disclosure relates to a rotor blade of a wind power installation, at least comprising a first rotor blade component having: a first end for arranging on the wind power installation, and a second end for connecting to a second rotor blade component; a second rotor blade component having: a first end for arranging on the first rotor blade component, and a second end wherein the first rotor blade component can be connected to the second rotor blade component at a separating point to the rotor blade, wherein the rotor blade has an aerodynamically open profile at the separating point.

The present invention relates to a system and method for attaching a wind turbine blade component to a surface of a wind turbine blade shell part at a component attachment position. The system comprises a blade shell part support for supporting the blade shell part, a jig comprising a jig base and a component platform for receiving and holding the wind turbine blade component in a first position above at least a part of the blade shell part, the component platform being arranged on the jig base and being at least vertically displaceable relative to the jig base by displacement means to allow the wind turbine blade component to be lowered from the first position to the component attachment position.

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.

This invention relates to a method and a wind turbine blade, wherein one or more airflow modifying devices are attached to a wind turbine blade having a base aerodynamic profile. The base aerodynamic profile is configured to substantially carry the structural loading of this modified wind turbine blade. The airflow modifying device is manufactured via 3D-printing and/or via 3D-machining and optionally coated or laminated before attachment. Once attached, the airflow modifying device may further be coated or laminated before working the outer surfaces into their finished shape.

A method for joining rotor blade segments of a rotor blade includes forming a female structural member having a receipt portion with a cavity and a structural portion. Further, the method includes securing the female structural member within a first blade segment. The method also includes forming a male structural member having a protrusion portion and a structural portion. Moreover, the method includes securing the structural portion of the male structural member within a second blade segment. In addition, the method includes inserting the protrusion portion into the cavity. As such, when inserted, an interface of the protrusion portion and the cavity forms one or more internal channels. Thus, the method further includes injecting adhesive into the one or more internal channels so as to secure the first and second blade segments together.
