Abstract
An apparatus is provided for an aircraft engine. This apparatus includes a variable area nozzle. The variable area nozzle includes a nozzle wall, a nozzle sleeve, an actuation system and a flowpath extending axially along an axis through the variable area nozzle and radially between the nozzle wall and the nozzle sleeve. The nozzle sleeve includes a shell, a liner, a cooling cavity and an ejector. The shell extends axially along and circumferentially about the axis. The liner axially overlaps and circumscribes the shell. The cooling cavity is formed by and radially between the shell and the liner. The ejector is arranged at a downstream end of the liner along the flowpath. The ejector fluidly couples the cooling cavity to the flowpath. The actuation system is configured to move the nozzle sleeve axially along the axis relative to the nozzle wall.
