Abstract
A direct drive wind turbine with a nacelle and a rotor including a hub, the nacelle and the hub connected in an interface region. The wind turbine includes a transport system for transporting hydraulic and/or pneumatic fluid from the nacelle into the hub. The transport system includes a rotary unit through which the fluid passes. A part of the rotary unit rotates in operation together with the hub. The rotary unit is positioned in the hub at a position distanced from the interface region facing away from the nacelle. Further disclosed are a transport system and a method of construction of such a direct drive wind turbine.
