ABSTRACT:
This disclosure is for a liner for the exit nozzle of a gas turbine engine. The liner is double walled liner with insulation material between the walls, and with a plurality of tubes extending through the walls and the insulation. Primary cooling is accomplished by film cooling through the tubes. During periods of low coolant medium flow, the liner provides a barrier against radiation and convection. The use of the insulating material allows both walls of the liner to carry the pressure loads.
