Hi @rschmehl ,
As you evoke Mark D. Moore on List of organizations , I opened a topic on Centrifugally Stiffened Rotor (CSR) as a model for an AWES? .
Indeed his purpose was “to put the entire structure in tension”. That can eliminate the cantilever effect of wing, and saving mass.
The CSR (blades + tethers in alignment) becomes a cone shaped due to the wind forces and I am not sure the aerodynamic forces on the blades will expand the rotor as a wing undergoing cantilever effect will do.
I would like to know your advice for this. Thanks.
