Abstract
An exhaust nozzle mixer for a turbojet engine is disclosed having a multi-lobed shroud extending from the exhaust nozzle of the turbojet engine, the shroud having a plurality of radially oriented lobes forming a plurality of gas mixing channels, each having a first cross-section in a plane extending substantially perpendicular to the longitudinal axis of the engine, as well as a flared lobe having a greater circumferential width than the remainder of the lobes to accommodate the engine mounting pylon. A baffle member extends radially inwardly from the mounting pylon toward the longitudinal axis of the engine such that the baffle extends into the flared lobe to form a plurality of cross-sections, each of such cross-sections being generally equal to each of remainder of the cross-sections of the multi-lobed shroud.
