Abstract: An augmentor for a gas turbine engine with a nozzle is provided having an outer casing, a liner, a stiffening ring, a plurality of fingerseals, and apparatus for fastening the stiffening ring and the fingerseals to the liner. The liner includes a plurality of first cooling apertures. The stiffening ring includes a plurality of second cooling apertures. The finger seals are positioned between the liner and the stiffening ring. Each fingerseal includes a plurality of cooling slots having a lengthwise axis. The cooling slots, first apertures, and second apertures are relatively positioned such that cooling air passing through the second cooling holes must thereafter travel within one of the cooling slots in a direction substantially along the lengthwise axis of the slot, before entering the first apertures.
