Abstract: A tip extension for a wind turbine blade is described. The tip extension comprises an adhesive dam inside a trailing edge region of the tip extension. A chordwise position of a surface of the adhesive dam is selected such that when the tip extension is fitted to a blade, a trailing edge of the blade projects into said surface. A method of attaching a tip extension to a wind turbine blade is also described. The method comprises sliding the tip extension onto the blade such that a trailing edge of the blade projects into the adhesive dam.

Abstract: In a first aspect of the invention there is provided a modular wind turbine blade comprising a first blade module and a second blade module for connection end to end, each blade module having an outer shell extending longitudinally in a spanwise direction, and extending transversely in a chordwise direction between a leading edge and a trailing edge. The first blade module comprises a first bearing surface and the second blade module comprises a second bearing surface, each bearing surface extends transversely and at least one of the bearing surfaces is angled such that the first and second bearing surfaces are mutually divergent when the first and second blade modules are arranged end to end. The modular wind turbine blade further comprises a tension element configured to span an interface between the first and second blade modules, the tension element comprising first and second mutually-opposed contact surfaces. The first contact surface is configured to engage the first bearing surface and the second contact surface is configured to engage the second bearing surface, wherein moving the tension element in a generally chordwise direction along the mutually divergent bearing surfaces causes the first and second blade modules to be pulled together in a generally spanwise direction, such that a pre-tensioned connection is established between the first and second blade modules.

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 and apparatus for fitting a tip extension to a wind turbine blade is described. The apparatus comprises a blade clamp and a tip extension lifting tool. The blade clamp is attached to the wind turbine blade at a location radially inboard of a tip end of the blade. The tip extension is supported in the tip extension lifting tool. The tip extension lifting tool is then lifted up to the tip end of blade. The lifting tool is connected to the blade clamp by means of a connecting device. The connecting device is adjustable to vary the separation between the blade clamp and the lifting tool. The method further comprises adjusting the connecting device to move the lifting tool towards the blade clamp such that the tip extension is pulled over the tip end of the blade.

Abstract: A method of attaching a tip extension in the form of a sock to a tip end of a wind turbine blade is described. The method involves attaching one or more adhesive-constraining dams to an outer surface of the blade at the tip end and/or to an inner surface of the tip extension. The adhesive-constraining dam(s) are arranged to define and constrain adhesive within one or more bond cavities between the outer surface of the blade and the inner surface of the tip extension when the tip extension is fitted to the blade. The adhesive dams include a friction-reducing layer arranged to facilitate sliding of the tip extension over the tip end of the blade. In preferred embodiments the adhesive dam comprises a foam strip having a PTFE layer on one side.
