Abstract: A prefabricated fairing for a wind turbine blade comprising fairing lips and exterior and interior fairing surfaces, wherein the fairing has a first fairing state in which the fairing is adapted to be mounted to a blade body of the wind turbine blade and a second fairing state in which the fairing is adapted to be fixed to the blade body, the fairing lips being compressed towards each other in the second fairing state relative to the first fairing state, wherein the fairing is brought from the first fairing state to the second fairing state upon application of a compression force onto the exterior fairing surface at fairing lips, wherein a difference between a first fairing lip distance in the first fairing state and a second fairing lip distance in the second fairing state is equal to or greater than 5 mm.

Abstract: A nut is configured to be secured to a bolt. The nut includes a main body that defines an axially aligned bore with threads disposed on an inner wall thereof. Further, the nut includes a dome-shaped head that has an axially aligned aperture and that is provided to be deformed by threads on the bolt when a predetermined burst-through torque is applied thereto.
