@tallakt , @Windy_Skies , @Rodread and the complete team of the forum,
Jean-Sébastion Brouillon indicates in one of his comments on Linkedin that he would like to be able to answer.
It would be desirable if you could indicate him the procedure to follow to open an account and be able to post, not only for this topic, but for all the topics on this forum. For now other topics may already be quite close, such as for example The Pyramid or Centrifugally Stiffened Rotor (CSR) as a model for an AWES? or A self-erecting passive Daisy (or other rotary). Thanks.
