ABSTRACT:
A variable area exit for a gas turbine engine discharge nozzle having a generally rectangular outlet includes a pair of rotatable flaps which extend between opposing sidewalls of the nozzle. Each of the flaps are provided with a profiled cam track which cooperates with a cam roller mounted on an axially moveable shroud ring. The shroud ring is coaxially disposed about the nozzle axis so that translation of the shroud causes the flaps to rotate and the nozzle exit area to alter.
