An exhaust duct assembly comprising:
- a case having an inner space;
- a duct inserted into an inner space of the case, the duct comprising an inlet through which an exhaust gas is introduced, and an exhaust port through which the exhaust gas is exhausted;
- a stiffener configured to attach the duct to the case;
- and
- a connector disposed on the exhaust port,
- wherein the duct, the stiffener and the connector are welded to one another such that at least a portion of each of the duct, the stiffener and the connector overlaps one another in a first direction,
- wherein the exhaust port has an exhaust port connection end,
- wherein the stiffener has a stiffener connection end disposed outside the exhaust port connection end in the first direction, and
- wherein the exhaust port connection end and the stiffener connection end are welded to each other to form a first welding part, and the first welding part is positioned inside the exhaust port connection end and the stiffener connection end.
An aircraft comprising a gas turbine engine and an exhaust duct assembly for exhausting exhaust gas discharged from the gas turbine engine to an outside, wherein the exhaust duct assembly comprises:
- a case having an inner space;
- a duct inserted into an inner space of the case, the duct comprising an inlet through which an exhaust gas is introduced, and an exhaust port through which the exhaust gas is exhausted;
- a stiffener configured to attach the duct to the case;
- and
- a connector disposed on the exhaust port,
- wherein the duct, the stiffener and the connector are welded to one another such that at least a portion of each of the duct, the stiffener and the connector overlaps one another in a first direction.
