An embodiment of the invention is a technique to suppress noise in a jet engine. A substantially annular fan nozzle is attached to a pylon and discharges a fan stream into atmosphere from an aft end thereof. A core nozzle discharges core stream into the atmosphere. The core nozzle has an exterior surface. A stream director is mounted on the pylon to direct the fan stream away from the pylon. At least a portion of the stream director is situated outside the aft end to maintain substantially constant flow area of the fan nozzle.
