Nacelle systems for mid-range aircraft

Safran Nacelles is one of the main integrators of aircraft engine nacelle systems in the world. On the medium-range commercial aircraft market, Safran Nacelles is the partner of the main aircraft manufacturers (Airbus, COMAC), and illustrates its technological lead through innovative, lighter, quieter and more electric nacelle systems.

The A320neo LEAP-1A nacelle

Safran Nacelles has the complete responsibility for the design and integration of nacelles on the A320neo powered by LEAP-1A engines. The only nacelle manufacturer in the world present in all market segments, Safran Nacelles has reinforced its position as world leader for medium-haul aircraft.

Latest generation nacelle

Powered by the CFM International LEAP-1A* engine, the Airbus A320neo incorporates the best Safran Nacelles technologies developed for its expanding portfolio of products, such as the nacelles which have been equipping the Airbus giant, the A380.

A performance model

More aerodynamic, lighter - with the use of composite materials, quieter - with an improved acoustic treatment and equipped with cascade thrust reversers, the A320neo nacelle contributes to the improvement in performance of both the propulsion system and the aircraft while offering a high level of reliability which has been the key to the success of the current aircraft version.

Characteristics of A320neo nacelle

  • Robust and reliable: technologies benefiting from all the experience from the A320, A330, A340 and A380 programmes
  • Lightweight: extensive use of composite materials
  • Efficient and silent: aerodynamic finesse and acoustic treatment
  • Optimised means of production: automation and innovative control devices
  • Ease of maintenance: criterion taken into account from the design phase on, based on feedback

An industrial organization close to the customer

Safran Nacelles has set up an industrial organization based on efficiency (automated lines and innovative inspection means), which is supported by its own production resources and backed by components provided from a carefully-selected international supply chain.

One of the industrial partners is U.S.-based Middle River Aerostructure Systems (ST Engineering), which provides the thrust reverser transcowl and cascades (both produced with composite materials), the thrust reverser actuation system, and engine build-up hardware associated with integrating the nacelle to the LEAP-1A powerplant.

When all nacelle components are received by Safran Nacelles (including the air inlet, fan cowls, thrust reverser, nozzle and EBU), they are assembled with the engine at Safran Nacelles' integration sites (Toulouse and Hamburg). The nacelle is also painted in the airline company colors before being delivered to the Airbus final assembly lines.
