Rotorcraft??? Then it aint necessarily a helicopter. I may have missed something in the discussion, but …..
….With no tailrotor illustrated, autorotational forces must power the main rotor. Therefore we already know the concept is proven and works in the autogyro.
Two questions Dave.
1. Can a retreating blade stall if it is being driven by airflow?
2. Is disc solidarity the key to this rotorcraft? ie many blades with a wide chord?
