The present invention relates to an exhaust duct assembly and an aerial vehicle including the same. According to one embodiment of the present invention, an exhaust duct assembly is disposed in a low-pressure turbine unit of a gas turbine engine and discharges exhaust gas to the outside. The exhaust duct assembly comprises: a duct which includes an inlet port, through which the exhaust gas flows in, an outlet port, through which the exhaust gas is discharged, and a mounting bore formed therethrough; a duct housing in which the duct is disposed and which includes a mounting hole into which the outlet port is inserted; a shaft housing which is disposed inside the mounting bore and has one end inserted into the duct housing so as to point toward the inlet port of the duct, and in which a driving shaft of the low-pressure turbine unit is disposed; and an annular sealing unit which is coupled to one end of the shaft housing and maintains an airtight seal between the driving shaft and the shaft housing. The present invention can extend the life of the exhaust duct assembly.
