These shutter-like things are Water-Air heat exchangers that discharge the loss Heat from Gearbox, Generator and Converter. Which things did you mean unter the Spoiler?
@@saasch_baasch I think you answered the question. It looks like a spoiler on a car and it has those shutters underneath. It's on top of the nacelle on the opposite side from the rotor. I guess the excess heat from the oil etc has to be dissipated somewhere. I've never seen such a design before. Thanks :-)
@@ATLRCFlyer that's correct. On the Spoiler are wind Measurements, Aviation Lights, Visibility Sensors and some more. The Heat exchanger Design is quite smart. higher Windspeed-> higher Power and Loss Heat, but also higher Heat exchange rate (exchange rate and Losses proportional to Windspeed). So this design saves extra blowers, that are inside together with the Heat exchangers on older Turbines.
Richtig erkannt, in diesem Modus "low wind idling" kann der Rotor bei wenig Wind und niedriger Drehzahl besser beschleunigen. Die Steuerung wartet in diesem Modus also, bis eine bestimmte Drehzahl erreicht ist und pitcht dann erst Richtung 0° um auf einschaltdrehzahl zu beschleunigen.
Cool 👍
What are those shutters for, or what are those things under the "Spoiler" ?

Mir ist aufgefallen, dass bei Vestas bei Windstille die Rotorblätter in einem Winkel von 45° stehen

vielen Dank für die Antwort 😁
