Eurocopter AS332 SED

The AS332 Serpentine Exhaust Duct (AS332 SED) redirects the exhaust gas to the aft of the aircraft via a bent ejector. The serpentine shape of the tailpipe provides a full optical block of the ejector hot metal from aft of the aircraft. An aerodynamic fairing covers the ejector. The device is supported by a structural frame which is installed within the aft engine cowling. The AS332 FCT is FAA certified as the Serpentine Exhaust Duct (SED), and is in operation.
