Abstract: 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.

Abstract: 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.

Abstract: A composite nacelle cover (1;22) equipped with main machinery components (9a;9b;10) for a wind turbine has a composite wall (3,4,5,6,7) constituting a first load-carrying structure for at least one component of a first part (9a;9b) of the main machinery components. The length of the conventional load-carrying frame can be reduced and a lot of weight of the overall nacelle structure be eliminated.

Abstract: A method of manufacturing composite laminate panel sub-elements (34) for subsequent assembling into a modular assembly structure (37), comprises the preprocessing steps of casting an elongate composite laminate sheet panel (18) having opposite first and second fiber-reinforced plastic face skins (19,21) sandwiching a core (35), a free first elongate edge (22) and an opposite second elongate free edge (24), demolding the elongate composite laminate sheet panel (18), cutting the demolded elongate composite laminate sheet panel (18) into (n) shorter sections (Sn), thereby providing sections (Sn) with at least one free cut edge (26; 32), a free first edge (22) having the same profile as the free first elongate edge, and a free second edge (22) parallel to the free first edge and having the same profile as the free second elongate edge, and machining at least a first coupling profile (27) along the at least one free cut edge (26; 32).
