Provided herein is a shear web support for wind turbine blade. Particularly, the present disclosure provides a frangible shear web support element that is designed to fail under certain specific conditions. The frangible support(s) enhance the structural rigidity of the shear web, allow for one-step mold closures, and rupture or disconnect once a predetermined condition (e.g. load threshold, load orientation/vector) is applied to the support element.

Disclosed is a wind turbine blade and a method for its manufacture. The wind turbine blade comprises an upwind side shell part, a downwind side shell part, a leading edge and a trailing edge. A flatback web is arranged at the trailing edge, which couples the upwind side shell part with the downwind side shell part, wherein the flatback web comprises at least one U-shaped end section with a recess, into which the upwind side shell part and/or the downwind side shell part is inserted and bonded to the U-shaped end section by an adhesive.

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.

Disclosed is a wind turbine blade and a method for its production. The wind turbine blade comprises an upwind side shell part and a downwind side shell part. The upwind side shell part and the downwind side part are bonded together along at least one joint. At said at least one joint, the upwind side shall part and the downwind side shell part are bonded at an internal glue flange as well as at an external glue flange. The glue flange can be produced by using a mould insert along which the glue flange is laminated.

A method for assembling an integrated wind turbine blade shell, comprising: attaching and distributing cleats onto the first wind turbine shell part at a distance from the first edge of a first wind turbine blade part, wherein a ledge surface and a rail of each cleat define, together with the interior surface, a ledge for supporting a glue flange; securing a clamp tool to the anchor of each cleat; resting the separately manufactured glue flange on the ledge surface of each cleat; closing the first and second wind turbine blade shell parts; actuate the clamp tools to clamp the glue flange between the clamp head of each clamp tool and interior surface; and detaching and removing the clamp tools from the cleats.

A rotor blade for a wind turbine including first and second blade segments extending in opposite directions from a chord-wise joint. The first and second blade segments include one or more shell members and internal support structures coupled to an inner surface of the one or more shell members of the first and second blade segments. The internal support structure of the first blade segment includes a beam structure extending between a first end at the chord-wise joint and a second end such that the beam structure is received by a receiving section of the internal support structure of the second blade segment. The rotor blade includes one or more spacer materials arranged within the first blade segment between an exterior surface of the beam structure and the inner surface of the one or more shell members to reduce a bond gap therebetween.
