A nacelle cover (240) for a wind turbine including a composite material elongate housing (245) defining an interior space for containing machinery components of the wind turbine, the housing (245) having a front end (247) for mounting to a tower (252) of the wind turbine, and an opposite rear end (248). At least one machinery component (125) of the wind turbine is mounted on the housing (245) at a position laterally spaced from the tower (252) in a longitudinal direction along the housing (245). The housing (245) includes a structural tube (242) which functions as a vertically displaceable cantilever beam carrying the load of the at least one machinery component (125) mounted thereon. In an unloaded state prior to mounting the at least one machinery component (125) on the housing (245), the rear end (248) is higher than the front end (247), and in a loaded state after mounting the at least one machinery component (125) on the housing (245), the rear end (248) is lowered as compared to the unloaded state by flexural elastic deformation of the structural tube (242).

A cabin cover and a wind turbine generator set are provided. The cabin cover includes: a cover, the cover including first plates, second plates, and at least one support beam, the first plate and the second plate being alternately arranged, at least one group of adjacent first plate and second plate being spaced apart from each other and being fitted to the support beam, and the first plates, the second plates, and the support beams jointly enclosing an accommodating chamber; and fasteners, two or more of fasteners being provided and disposed in the accommodating chamber, at least one fastener detachably connecting the first plate to the support beam, and at least one fastener detachably connecting the second plate to the support beam.

A prefabricated fairing for a wind turbine blade, the fairing extending along a fairing profile terminating at fairing lips and comprising exterior and interior fairing surfaces and a plurality of layers including fibre-reinforced layers and an exterior erosion-resistant elastomer layer forming a portion of the exterior fairing surface and being configured for defining the leading edge of the wind turbine blade, the fairing further comprises a cured first resin binding the erosion-resistant elastomer layer and the one or more fibre-reinforced layers together.

A nacelle cover (100) for a wind turbine includes an elongate housing (105) and the front end (107) of the housing (105) is mounted on a bed plate frame (420) which is affixed to the tower (122), the bed plate frame (420) supporting at least one part of a drive train (124) of the wind turbine. At least one machinery component (125) is mounted on the housing (105) at a position laterally spaced from the bed plate frame (420) in a longitudinal direction along the housing (105). The housing (105) includes a structural tube (128) which functions as a vertically displaceable cantilever beam carrying the load of the at least one machinery component (125) mounted thereon.
