Innovative nacelle system takes off with C919 jetliner

The first flight of the COMAC C919 on May 5 was the debut of Nexcelle’s innovative engine nacelle system, which provides improved operating performance and efficiency, lower weight and easier maintenance for the twin-engine Chinese jetliner’s integrated propulsion system.

The C919 nacelle system – developed with expertise from the Nexcelle 50/50 joint venture’s two parent companies, Safran Nacelles and GE Aviation’s Middle River Aircraft Systems – is incorporated into the C919’s LEAP-1C turbofan engines, developed by CFM International.

Key features of Nexcelle’s nacelle system for the LEAP-1C include an all-new translating O-Duct thrust reverser configuration; a fan cowl that is structurally integrated to the engine; and an integrated mounting system for reduced engine distortion and enhanced on-wing performance.

A major innovation in Nexcelle’s nacelle design is its one-piece composite O-Duct thrust reverser configuration, which replaces the two-piece “D” doors on traditional thrust reversers. 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. The O-Duct deployment is performed with an evolved electrical thrust reverser actuation system (ETRAS), replacing heavier hydraulics typically used in thrust reversers and improving maintainability.

Another of the nacelle system’s technological advances is its low drag front end that incorporates an air inlet with a one-piece lip skin – the largest of its kind to enter production on a large commercial jet engine, improving airflow and contributing to lower noise. Additionally, the inlet has a directed flow nozzle deicing system, which more efficiently swirls engine bleed air within the inlet lip, thereby providing weight, efficiency and maintainability improvements from traditional nacelle deicing systems.

Nexcelle’s LEAP-1C nacelle also incorporates the extensive use of lightweight and state-of-the-art noise-attenuating composite materials, benefitting from the joint venture parent companies’ proven experience in their respective nacelle and thrust reverser product lines.
