Many people refer to fact that in theory a helicopter should not fly due to dynamics being all wrong, well most helis are as streamlined as their designers try to make them.
Now if you put a stonking big engine into a oblong box, with a MR on the top and stuck a tail rotor on the side, how much power would be needed to overcome the forward wind/air resistance. And does it really need a TR to be out on a pylon, on said box you could fit a TR on each side
For if such simplistic thing as a box shaped Helicopter flying could be made to work, would that not be able to be more capable of carrying things like cargo and such items, without the constraints of intrustions like curves that make pax almost hug each other, even in bigger things!
I know its very early , but up before the sun always sets me off looking at odd ways of doing things!!
