The present invention relates to an exhaust duct assembly and an aerial vehicle including same. The exhaust duct assembly according to an embodiment of the present invention 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 that 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 in a hollow shape; 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.

    La présente invention se rapporte à un ensemble conduit d'échappement et à un véhicule aérien muni de ce dernier. L'ensemble conduit d'échappement selon un mode de réalisation de la présente invention est disposé dans une unité de turbine basse pression d'un moteur de turbine à gaz et évacue un gaz d'échappement vers l'extérieur. L'ensemble conduit d'échappement comprend : un conduit comprenant un orifice d'entrée, dans lequel s'écoule le gaz d'échappement, un orifice de sortie, à travers lequel le gaz d'échappement est évacué, et un alésage de montage formé dans une forme creuse ; un logement de conduit dans lequel est disposé le conduit et qui comprend un trou de montage dans lequel l'orifice de sortie est inséré ; un logement d'arbre disposé à l'intérieur de l'alésage de montage et doté d'une extrémité insérée dans le logement de conduit de façon à pointer vers l'orifice d'entrée du conduit, et dans lequel est disposé un arbre d'entraînement de l'unité de turbine basse pression ; et une unité d'étanchéité annulaire accouplée à une extrémité du logement d'arbre et maintenant un joint étanche à l'air entre l'arbre d'entraînement et le logement d'arbre.
