Is the theory of Autorotation,driving-driven region outdated?
This idea of driving the rotor from the inner region cannot be true.
After considerable thought on the matter, I say that the entire outer lifting portion of the rotor is a gliding wing section, and as such, provides for its own rotational thrust in the same manner as any glider.
I boldly claim that there is no such thing as a" driving" and "driven" region on a vertical autorotation.
Are the textbooks outdated?
