Not so. It's having to generate lift with the rotating rotor blades.
The work is proportional to the torque on the rotor shaft and the
number of revolutions.
An infintely large rotor turns at zero RPM
There are no revolutions.
if it is also an infinitely heavy helicopter I'd like to see the proof
if it isn't infinitely heavy why bother with rotors when you could just
use cavorite?
