Must be a very slow day on PPrune!
Well if we are going to push then a whole bunch of components will have load forces at 180 degs to what they have now ( compression vs tension ) but why would we want to do it that way? Think of the FOD implications. Controls would be very sensitive what with the mass of the helicopter above the rotor system much like balancing an umbrella on your fingertip - the mind boggles!
Tried to push a rope lately?
Shades of the Cessna 337 and inumerable WW1 aircraft.
Have a dood day everyone and thanks for the chuckle.
