Cooling liner for convergent-divergent exhaust nozzle

Patent ·
OSTI ID:7082957
A method is described for recovering the energy of working medium gases compressed in the compression section of a gas turbine engine and utilized to cool a convergent-divergent exhaust nozzle in such an engine, comprising the steps of: flowing the working medium gases from the compression section to the convergent section of the convergent-divergent exhaust nozzle; passing the working medium beneath a liner in the upstream region of the convergent section to cool the exhaust nozzle; and discharging the working medium from the liner into the engine exhaust flow at the convergent section upstream of the nozzle throat at a point at which the static pressure of the working medium under the liner is substantially equal to the static pressure of the exhaust flow.
