Nexcelle provides first components for CFM International’s LEAP-1C engine

Nexcelle – the joint venture of Aircelle (Safran) and GE Aviation’s Middle River Aircraft Systems for a new generation of engine nacelles on integrated propulsion systems – has delivered its first O-Duct nacelle to equip CFM International’s LEAP-1C engines for the COMAC C919 jetliner. Developed and manufactured by Aircelle, this innovative O-Duct marks a milestone in Nexcelle’s production hardware deliveries, and is to be used – together with other nacelle components – for engine flight test. Nexcelle has also delivered the first LEAP-1C air inlet from Middle River. The hardware has been installed on a LEAP development engine currently undergoing tests. The one-piece composite O-Duct delivered by Nexcelle is a technology breakthrough in nacelle design for integrated propulsion systems, replacing a traditional thrust reverser’s two-piece “D” doors. When deployed, the O-Duct moves aftward to the reverse thrust position, eliminating drag links in the engine’s secondary flow-path, enhancing the airflow path and improving fuel consumption, while also increasing thrust reverser efficiency.
