A WIND TURBINE, A METHOD FOR ESTABLISHING AT LEAST ONE APERTURE IN THE SPINNER ON THE HUB OF A WIND TURBINE ROTOR AND USE OF A WIND TURBINE

摘要

The invention relates to a wind turbine (1) comprising a rotor (4). The rotor (4) includes a hub (11) from which a number of wind turbine blades (5) extend, and a spinner (12) mounted on the hub (11), wherein the spinner (12) comprises one or more apertures (13). The wind turbine (1) is characterized in that it comprises one or more aperture covers (14) for entirely or partly covering one or more of the apertures (13) in the spinner (12) and in that the wind turbine (1) further comprises one or more aperture adjustment means (15) for adjusting the effective size of one or more of the apertures (13), by displacement of one or more of the aperture covers (14). The invention further relates to a method for establishing at least one aperture (13) in the spinner (12) on the hub (11) of a wind turbine rotor (4) and use of a wind turbine (1).
