Abstract: A wind turbine nacelle configured for mounting on a wind turbine tower and housing a rotor-supporting assembly defining a rotation axis. The nacelle comprises a main unit arranged to be connected to a wind turbine tower and housing the rotor-supporting assembly. A crane is placed outside the main unit and connected directly to the main frame.

Abstract: A wind turbine nacelle configured for mounting on a wind turbine tower and for supporting a rotor-supporting assembly, the nacelle comprising a main unit, and at least two auxiliary units. To increase flexibility and improve assembly and maintenance procedures of the wind turbine, the auxiliary unit comprises at least two auxiliary units each accommodating at least one wind turbine component, e.g. a converter or a transformer. The auxiliary units are attached individually to the same wall of the main unit, e.g. to a side wall or a rear wall.

Abstract: A wind turbine blade comprising: a first blade portion having a shell that defines a suction side, a pressure side, a leading edge, and a trailing edge of the blade, the first blade portion further including a first blade portion end surface at one end of the first blade portion; a second blade portion having a shell that defines a suction side, a pressure side, a leading edge, and a trailing edge of the blade, the second blade portion further including a second blade portion end surface at one end of the second blade portion, wherein the first blade portion and the second blade portion are configured to be coupled together at the first and second blade portion end surfaces; and a connection joint for coupling the first and second blade portions together, wherein the connection joint includes: a first insert embedded in the first blade portion; a fitting integral with the first insert and projecting from the first blade portion end surface toward the second blade portion end surface; a second insert embedded
