Abstract: A wind turbine rotor blade has a spar cap including conductive material, and a lightning conductor extending over the spar cap. There is a non-conductive layer between the lightning conductor and the spar cap. An equipotential bonding element electrically bonds the lightning conductor to the spar cap. The non-conductive layer is discontinuous to define a gap, and the equipotential bonding element extends through the gap.

Abstract: A modular wind turbine blade is described. The modular wind turbine blade comprises first and second blade modules having spar caps embedded within their outer shells. The spar caps taper in thickness resulting in tapered recesses being defined in the outer shells. The tapered recesses in the first and second blade modules are aligned when the modules are placed end-to-end to form a continuous double-tapered channel. A connecting member having a double-tapered structure is bonded in the channel to connect the modules together. The invention also provides a mould for making the blade modules in which the mould surface includes a protruding elongate feature having a tapered portion configured to form the recesses in the outer shells. During layup and moulding of the outer shells, spar caps are supported on top of the tapered portion of the elongate feature.

Abstract: A method of making a modular wind turbine blade is described. The modular blade comprises first and second blade modules connected together by a scarf joint between tapered spar caps of the respective blade modules. According to the method, first and second blade modules are laid up in the same mould assembly. A separating layer is arranged between the layups of the first and second module in a joint region of the mould. The separating layer has a thickness corresponding to a required bond thickness in the scarf joint when the modules are bonded together.

Abstract: A method of making a composite wind turbine component in a mould is described. The method comprises the steps of: providing a mould; providing one or more first layers (20) of material; arranging the first layer(s) of material in the mould; arranging one or more second layers (20) of material on top of the first layer(s) to form a stack (22); and securing the second layer(s) to the first layer(s) by means of one or more fasteners (24). The steps of the method can be performed in any suitable order. The fasteners (24) each comprise a filament having a first retaining element at a first end and a second retaining element at a second end. To secure the second layer(s) to the first layer(s), the first retaining element of each fastener is inserted through the second layer(s) and the first layer(s) such that the first retaining element is located on one side of the stack and the second retaining element is located on the other side of the stack, with the filament extending through the stack (22).

Abstract: A method of making a wind turbine blade (10) having a shell (14, 16) of varying thickness. The method comprises providing a blade mould (30), the mould defining first (32) and second zones (34); arranging layers of fibrous material (42) for forming a first part of the shell having a first thickness in the first zone (32) of the mould, arranging layers of fibrous material for forming a second part of the shell having a second thickness greater than the first thickness in the second zone (34) of the mould, and supplying resin (41) to the mould (30). The method further comprises pre-heating the mould in the first zone (32) to a first temperature, and pre-heating the mould in the second zone (34) to a second temperature greater than the first temperature before supplying the resin (41) to the mould (30).
