In an aircraft propulsion system which includes a pusher propeller driven by an engine which is mounted to a fuselage by a pylon, the invention concerns apparatus for reducing turbulence generated by the pylon. In one example, a flap or vane attached to the pylon postpones the onset of flow separation, thereby reducing turbulence.
