Abstract
Disclosed is a device for cooling the trailing edge segment of a liner on a convergent flap of a nozzle on a gas turbine engine. The trailing edge cooling device enhances the cooling of the liner without introducing turbulence into the coolant, thereby allowing the coolant to be used to film cool downstream components. In addition, the present invention increases the longitudinal rigidity of the trailing edge of the liner to provide support for the trailing edge without significantly reducing the lateral flexibility of the liner required for thermal expansion.
