Greaney,
Thanks. The idea of the pusher propeller obtaining an advantage from the increased mass flow, due to the rotor generated translational lift is an interesting one. Do you think that tractor propeller might negate this advantage by decreasing the effectiveness of the rotor due to a decreasing of the mass differential between the top and the bottom of the rotor?
Mart,
My knowledge of fluid dynamics is '0'. However, I dumbly believe that the laminar/turbulent flow on the rotorcraft cannot be compared with the laminar/turbulent flow on the submarine. This is because their Reynolds numbers are so very different.
Are you suggesting that the pusher's propeller be replaced by a helicopter's tail rotor'?
Sorry, but loosey-goosey rotors just won't do.
Dave
