SIMONE

Hi all,i am a student from politecnico di milano and i am using Qblade to do a structural analysis of a HAWT, and i have a problem: the control procedure adopted is to maintain constant cp from vcut-in=3 to vaverage wind=8 , i'm trying then to make a structurale analysis with wind speed and loads (taken from BEMsimulation) at v=13.7 = vrated. I dont really get how the input " design rotational speed i " nfluences the FEM analysis ( i saw that for example if i increse it the stress increase). Second,...
