Zusammenfassung:A rotor hub for a wind turbine which can be configured between an in use or 'operational' configuration and a transportation configuration. In the transportation configuration the rotor hub has a reduced external size compared to when it is in the operational configuration. The rotor hub comprises a generally hollow hub body having a first end and a second end spaced along a hub rotational axis, wherein the first end defines a rotor connection flange configured to connect the rotor hub to a main shaft, and wherein a second end defines a nose region of the hub. The hub also defines at least one blade aperture defined between the first end and the second end, a blade bearing associated with the or each blade aperture, and a pitch actuator associated with the blade bearing. In the operational configuration a portion of the pitch actuator protrudes from the nose region of the hub body by a first distance, whereas in the transport configuration the portion of the pitch actuator protrudes from the nose region of the hub body by a lesser extent than when in the operational configuration. Therefore it will be appreciated that the pitch actuator is energised to change the extent to which the pitch actuator protrudes through the nose region of the hub body.
