Abstract
An exhaust nozzle for a gas turbine engine comprises an exhaust duct and a first flap. The exhaust duct is configured to receive an exhaust flow of gas from a combustor of the gas turbine engine. The first flap is rotatably coupled to the exhaust duct for rotation about a first axis of rotation. Further, the first flap at least in part defines an exhaust gas passageway configured to convey the exhaust flow of gas to an exterior of the gas turbine engine. Additionally, the first flap comprises a first pin. The exhaust nozzle comprises a first moveable cam having a first moveable slot configured to slidably receive the first pin. The exhaust nozzle is configured such that movement of the first moveable cam causes the first flap to be moved about the first axis of rotation between a first inner position and a first outer position.
