ABSTRACT:
A cooling control system for a convergent-divergent gas turbine exhaust nozzle which permits ducting of cooling air during the non-augmented mode of engine operation. A Curtain Liner is hinged at the forward end and able to fully collapse against the nozzle convergent section cutting off cooling flow. A door, connected to the nozzle, when opened allows cooling air to pass between the nozzle and the curtain liner causing the liner to move away from the nozzle wall and the cooling process to take place. Movement of the curtain is limited by a link at the end remote from the hinge.
