Aircraft provided with an exhaust duct coupled to a stabilization system
An aircraft provided with at least one exhaust duct for discharging gases from an engine. The exhaust duct is partly accommodated in an internal housing of the aircraft, the housing being separated from an external environment situated outside the aircraft by at least one cowl that is able to move in relation to a load-bearing structure of the aircraft. The exhaust duct comprises an exhaust segment passing through a passage of the cowl without touching the cowl. A space separates the exhaust segment from the cowl. The aircraft comprises at least one stabilization system coupled to the exhaust duct, the stabilization system comprising a stiffening ring secured to the exhaust duct and at least one fastening connecting the exhaust duct to the cowl.
