The invention provides a method of forming a wind turbine blade. The blade has a main blade module that defines a main body of the blade and includes a first mating feature, e.g. a tongue. The blade also includes a separate edge module that defines at least part of a trailing edge of the blade and includes a second mating feature, e.g. a recess. The method includes applying an adhesive to at least one of the first mating feature and the second mating feature. The method includes arranging the separate edge module relative to the main blade module such that the first and second mating features are mutually adjacent. The method includes applying a pressure force to squeeze the adhesive to bond the first and second mating features together. The pressure force is caused by removing air from, or injecting air into, an air sealed region.

Method of forming a wind turbine blade

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.

Relating to wind turbine blades

A wind turbine rotor blade lightning receptor arrangement () is provided with an electrically conductive block () and a shielding component (). In use, the electrically conductive block () forms an electrical bridge between a receptor element () of a lightning protection system and a down conductor () of the lightning protection system. The electrically conductive block () comprises a first engagement surface () for, in use, receiving the receptor element (). The shielding component () overlays a portion of the first engagement surface () of the electrically conductive block (), while leaving open an area for receiving the receptor element ().

Wind turbine rotor blade lightning receptor arrangement

A rotor blade for a wind turbine comprising: an internal blade cavity defined by two opposing internal surfaces of two shells of the rotor blade; a receptor block forming part of a lightning protection system and disposed within the internal blade cavity; and a centralising device that spaces the receptor block from the two opposing internal surfaces of the shells such that the receptor block lies centrally within the internal blade cavity. The receptor block is therefore in a desired position for installing receptors for lightning discharge.
