Abstract: A wind turbine blade assembly comprising: a first wind turbine blade portion having a first attachment portion and a first metallic plate, a second wind turbine blade portion having a second attachment portion and a second metallic plate, and at least one tension member for coupling to the first and second attachment portions to join the first wind turbine blade portion to the second wind turbine blade portion, wherein the first and second metallic plates are configured to abut in compression due to tension in the tension member when the first wind turbine blade portion is joined to the second wind turbine blade portion with the at least one tension member. Also, a method of joining blade portions to construct a blade.

Abstract: A split wind turbine blade includes a connection joint for coupling a first and a second blade portion together. At least one of the blade portions includes electrically conductive material, and a hole formed in an end surface of the blade portion. A portion of the electrically conductive material is revealed on a surface of the hole. The connection joint includes a metal insert embedded in the hole such that the metal insert 10 forms an electrical path with the electrically conductive material revealed on the surface of the hole.

Abstract: Improvements relating to wind turbine blades A wind turbine blade is described that comprises a main blade and one or more separate edge modules attached to the main blade module. The main blade module defines a main body of the blade, and the separate edge module(s) defines at least part of a leading edge or a trailing edge of the blade. A down conductor for a blade lightning protection system is embedded within the edge module.

Abstract: A wind turbine blade comprising a lightning protection system, which is at least partly disposed in an inboard portion of the blade. The lightning protection system comprises a plurality of inboard down conductor cables and a diverging electrical junction. The lightning protection system may comprise a down conductor cable having root and tip portions having insulation with different electrical breakdown voltages and/or a down conductor cable portion and a supporting component to hold the cable portion in free space in a position near or on a camber line of the blade aerofoil section, so that the cable portion is spaced apart from at least one electrically conductive structural component.
