Patent number: 11746744Abstract: A wind turbine rotor blade having a blade shell with a generally chordwise layup of fibre plies and a generally spanwise spar cap. A lightning conductor extends over the spar cap, and the spar cap includes conductive material. An equipotential bonding element electrically bonds the lightning conductor to the spar cap. The equipotential bonding element extends between an outboard edge of one stack of the fibre plies and an inboard edge of an adjacent stack of the fibre plies, which overlap to define an overlapping edge region.Type: GrantFiled: December 2, 2020Date of Patent: September 5, 2023Assignee: Vestas Wind Systems A/SInventors: Lasse Lykkegaard, Rens Christiaan Verhoef, Gurmukh Singh, Nathan A.

Patent number: 11644011Abstract: 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.Type: GrantFiled: July 5, 2019Date of Patent: May 9, 2023Assignee: Vestas Wind Systems A/SInventors: Toby Collard, Nathan A.

Patent number: 10871150Abstract: A wind turbine blade comprising a main blade portion having a longitudinal axis that extends between a root end and a tip end, wherein a leading edge and a trailing edge extend between the root end and the tip end, and a conductive blade tip module mounted to the tip end of the main blade portion; wherein the tip end is truncated and has a blade tip interface that defines an outer edge, and wherein the blade tip module is configured to fit against the blade tip interface such that a lip of the blade tip module overlaps the outer edge of the blade tip interface. Since the blade tip module is configured to overlap the tip edge of the blade, this protects the junction between the two components from erosion due to weathering.Type: GrantFiled: July 27, 2017Date of Patent: December 22, 2020Assignee: Vestas Wind Systems A/SInventors: Jakob Hjorth Jensen, Lasse Lykkegaard
