Aerodynamic Analysis and Optimisation of Wingtip-Mounted Pusher Propellers: An investigation into the propulsive gains and optimal geometry of small-scale propellers

Ever since the late seventies great engineering effort has gone into increasing the fuel efficiency and reduction of the noise profile of aircraft. A concept that has been explored is the wingtip-mounted (pusher) propeller. In all wings energy is lost due to the lift-induced vortex at the wingtip. Wingtip-mounted pusher propellers can recover...
