Abstract:
An exhaust nozzle assembly includes an inner liner exposed to hot combustion gases and an outer liner spaced a radial distance from the inner liner to form an annular chamber. The inner liner includes a hot side that is directly exposed to the hot combustion gas flow and a cold side is exposed to cooling air within the chamber. The outer liner includes an outer surface exposed to cooling air flow up to a restriction preventing communication of cooling air flow. A plenum is attached to the outer liner to define a plenum chamber that extends into an end portion. The plenum chamber receives cooling air flow from a supply opening and communicates that air to an end portion through a plurality of impingement openings that provide impingement flow of cooling air outboard of the restriction.
