    Abstract: A method of making a wind turbine blade incorporating a lightning protection system includes providing a blade mold; arranging a protruding element in the mold; arranging an electrically conductive layer over the protruding element; arranging one or more structural layers and/or structural components over the conductive layer; consolidating the layers under vacuum to form a blade shell having the conductive layer proximate an outer surface of the shell; separating the protruding element from the blade shell to define a recess with the conductive layer extending into the recess; providing an electrical component adjacent an inner surface of the shell; and electrically connecting the conductive layer to the component. An end portion of the connecting member is housed in the recess such that a surface of the connecting member abuts the conductive layer inside the recess.

    Abstract: A wind turbine blade assembly is described. The wind turbine blade assembly comprises: first and second blade sections connected together, each blade section having a shell defining an aerodynamic profile and each section comprising lightning protection components; a substantially enclosed interior region defined in part by the shell of the first blade section and in part by the shell of the second blade section; a first connector located in the interior region, the first connector being attached to the first blade section and electrically connected to the lightning protection components of the first blade section, the first connector defining a contact surface; a second connector located in the interior region, the second connector being attached to the second blade section and electrically connected to the lightning protection components of the second blade section, the second connector defining a contact surface opposed to and in contact with the contact surface of the first connector. The wind turbine blade assembly further comprises a first fastener extending through the shell of the first blade section into the interior region, the first fastener having a threaded shank that extends at least partially through the first and second connectors, and the first fastener clamps the contact surfaces of the first and second connectors together to form a torqued connection between the first and second connectors.
