Abstract
A wind turbine blade comprising a main blade portion having 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 that abuts the tip end of the main blade portion; wherein the conductive blade tip module comprises an elongate body defining a longitudinal axis transverse to a spanwise axis of the blade, and wherein the conductive blade tip module has a length in a direction along said longitudinal axis that is greater than a chord length of the blade tip interface.

A wind turbine blade having a lightning protection system comprising:
- a main blade portion having 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 connected to a blade tip interface at the tip end of the main blade portion and further connected to the lightning protection system of the wind turbine blade,
- wherein the conductive blade tip module comprises an elongate body having a length defining a longitudinal axis transverse to a spanwise axis of the main blade portion and a width that extends along the spanwise axis of the main blade portion,
- wherein the length of the conductive blade tip module is greater than a chordwise length of the blade tip interface, and
- wherein the blade tip interface 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.
A wind turbine blade having a lightning protection system comprising:
- a main blade portion having a root end and a tip end with a leading edge and a trailing edge extending between the root end and the tip end, wherein the tip end is truncated to define a blade tip end face;
- and
- a conductive blade tip module connected to a blade tip interface located at the blade tip end face of the main blade portion and further connected to the lightning protection system of the wind turbine blade,
- wherein the conductive blade tip module comprises an elongate body defining a longitudinal axis transverse to a spanwise axis of the main blade portion, and wherein the conductive blade tip module has a length in a direction along the longitudinal axis that is greater than a chordwise length of the blade tip end face, and
- wherein the blade tip end face defines an outer edge wherein the conductive blade tip module is configured to fit against the blade tip end face such that a lip of the conductive blade tip module overlaps the outer edge of the blade tip end face.
