Happy new year to each and every one of you, wish you all the best ;)
Concerning the effect of the rotating blades, it isn't included in my study. In fact, even the contact between the tower and the ground and the wind turbine isn't included - the only concern is the tower by itself, as if it was standing by itself and subjected to a certain number of forces: the wind, the wind drag (calculated in function of the diameter using Reynold's coefficient for a smooth cylinder), and the weight of the wind turbine platform on the top of the tower.
To get it all steady and isostatic with respect of all those constraints we added a shroud to support the tower.
Thanks to all of you, I got all the answers to my questions. If any of you want any more details about the project I'll be happy to provide them.
