I believe the counterotating propellor was designed to
minimize the effects of torque roll on wave off from a carrier's deck which in
those days was fore and aft and had a crash barrier to stop you getting into the
aircraft parked forward of the barrier, if you screwed up and missed the
wire.
There were actually two propellors turning in opposite
sense. This negated the torque roll when going to full power. Imagine the
gearing involved to make this happen.
And guys this all I know! I do not understand the
engineering factors involved in this but I have seen them in action.
Please do not ask me to explain!!!!
