Abstract
An exhaust nozzle includes circumferentially adjoining primary flaps and seals hinged at forward ends to an annular casing. The primary flaps and seals are actuated between open and closed positions for varying flow area of a throat defined at the aft ends thereof. Respective pluralities of primary liners and seal liners are spaced radially inwardly from respective ones of the primary flaps and primary seals and circumferentially overlap each other. The primary liners and seal liners collectively define an annular flap duct disposed in flow communication with a cooling duct inside the casing for receiving a coolant therefrom for cooling the primary flaps and seals. The primary liners and seal liners are mounted to the primary flaps for pivoting movement therewith.
