Wind turbine blade leading edge pairing

A method of fitting a leading edge fairing to a wind turbine blade, comprising:

• providing a blade body having a root, a tip, and a longitudinal direction extending between the root and the tip, wherein the blade body has a first channel extending in the longitudinal direction and a second channel extending in the longitudinal direction;
• providing a leading edge fairing having a generally C-shaped profile with a leading edge, a first trailing edge, and a second trailing edge, the leading edge fairing further including a first projection adjacent the first trailing edge and a second projection adjacent the second trailing edge;
• and
• attaching the leading edge fairing to the blade body by inserting the first projection in the first channel whereby the first projection extends in the longitudinal direction, and inserting the second projection in the second channel whereby the second projection extends in the longitudinal direction.

A leading edge fairing for attachment to a blade body of a wind turbine blade, the leading edge fairing comprising:

• an aerodynamic surface defining a generally C-shaped profile with a leading edge, a first trailing edge, and a second trailing edge,
• a reverse surface opposite the aerodynamic surface,
• a first projection adjacent the first trailing edge extending away from the reverse surface and extending in a longitudinal direction of the leading edge fairing, wherein the first projection is configured to be received in a first channel of the blade body in a first mechanical interlock, which first channel extends in a longitudinal direction of the blade body between a root and a tip of the blade;
• and
• a second projection adjacent the second trailing edge extending away from the reverse surface and extending in the longitudinal direction of the leading edge fairing, wherein the second projection is configured to be received in a second channel of the blade body in a second mechanical interlock, which second channel extends in the longitudinal direction of the blade body.

A wind turbine blade, comprising:

• a blade body having a root, a tip, and a longitudinal direction extending between the root and the tip, the blade body further including a groove extending in the longitudinal direction;
• a moulded component received in the groove and including at least one channel extending in the longitudinal direction;
• and
• a leading edge fairing having at least one projection extending in the longitudinal direction, the at least one projection extending into the at least one channel of the moulded component to couple the leading edge fairing to the blade body.
