Abstract
An aircraft propulsion system includes at least one pusher propeller mounted to a nacelle mounted to the aircraft by a pylon which produces a wake which impinges upon the propeller. The wake from the pylon is modified to reduce noise and vibration produced by the propeller interaction with the wake. The propulsion system may include a pair of counterrotating pusher propellers.
