En vindmølle og en fremgangsmåde til etablering af mindst en åbning i spinneren på en vindmøllerotors nav

摘要

A wind turbine includes a rotor having a hub from which a number of wind turbine blades extend, and a spinner mounted on the hub, wherein the spinner includes one or more apertures. The wind turbine is characterized in that it includes one or more aperture covers for entirely or partly covering one or more of the apertures in the spinner and in that the wind turbine further includes one or more aperture adjustment mechanisms for adjusting the effective size of one or more of the apertures, by displacement of one or more of the aperture covers. 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 are also contemplated.
