  • Cooling liner for convergent-divergent exhaust nozzle
    Patent number: 4643356
    Abstract: A gas turbine exhaust nozzle capable of long term, reliable operation is disclosed. Nozzle cooling concepts specifically directed to convergent-divergent exhaust nozzles are developed. The exhaust nozzle disclosed has a cooling liner which is strategically positioned in the nozzle to take advantage of aerodynamic conditions along the axial length of the nozzle.

  • Pressure actuated collapsible curtain liners for a gas turbine engine nozzle
    Patent number: 4074523
    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.
