Abstract:
An exhaust assembly for use with a gas turbine engine includes an exhaust duct and a damper system coupled to the exhaust duct. The exhaust duct is configured for fluid communication with the gas turbine engine to receive hot exhaust gases produced by the gas turbine engine. The exhaust duct includes a plurality of panels that define an exhaust passageway. The damper system is coupled to one of the plurality of panels and is configured to dampen vibration of the exhaust duct during use of the gas turbine engine.
