Multiple rotor vs single rotor efficiency
Suppose I built a VTOL with ten small independent electric motor powered rotors of 4 feet diameter each for a total of 125 sq.ft.
And for comparison a single rotor helicopter with the same 125 sq. ft.
The multi-rotor design could be built very light since the failure of one rotor could be controlled. Sort of like the guy that tied 50 weather balloons to a lawn chair.
Considering the reduced weight, which rotor system would be the best in terms of payload?
Any thoughts appreciated.
