Abstract
Disclosed is a wind turbine with a nacelle and a rotor, the rotor including a number of blades and a hub, the nacelle and the hub being connected with each other in an interface region, the wind turbine further including a transport system for transporting hydraulic and/or pneumatic fluid from the nacelle into the hub. The transport system includes a rotary unit as a connection through which the fluid passes and a part of which rotates in operation together with the hub which rotary unit is positioned in the hub at a position distanced from the interface region facing away from the nacelle, the transport system further including a pipe system leading from the interface region into the hub to the rotary unit and being fixed in its position. The disclosure also concerns a method of construction of such wind turbine.
