Abstract
A discharge nozzle is provided having a centerbody and a conduit enclosing the centerbody and is operable to receive exhaust flow from a turbine discharge of a gas turbine engine. In one form the centerbody is symmetric and extends along the flow direction, rising away from a reference axis to a maximum position before falling and converging on the reference axis. A set of rings is disposed between the centerbody and the conduit and are positioned between the centerbody and the conduit.
