Robust and reliable: technology based on the A320, A330, A340 and A380 programs

Light: composite materials make up more than 60% of the nacelle

Efficient and quiet: aerodynamic finesse and acoustic treatment

Aerodynamic and light, the Airbus A320neo nacelles contribute to both the aircraft and propulsion system performance. They also enable engine noise reduction and perform a braking function on landing. A 24/7 after-sales service is available to support the Airbus A320neo nacelles.

A320neo nacelle thrust engines

The A320neo nacelles are equipped with cascade thrust reversers. Panels inside the nacelles open when activated by the pilot, to redirect the cold airflow towards the front, thus generating the counterthrust which assists with braking on landing. The thrust reversers ensure braking of the plane, especially on short, wet, snowy or icy landing strips.

Safran Nacelles is an expert in the assembly of aerostructures such as thrust reversers. The company has control over all the parts assembly processes: they are positioned meticulously, adjusted to the structure using shimming, drilling, milling, countersinking, bonding and riveting.

Engine noise reduction acoustic treatment

Honeycomb acoustic treatment is applied in strategic areas of the A320neo nacelle composite panels. Hundreds of thousands of holes are drilled in the composite skin so that the noise can disperse and be captured in the honeycomb core. This process significantly reduces the engine noise. Safran Nacelles holds a unique expertise in engine environment acoustic technology.

Optimized production resources

Innovative inspection systems and automation

Safran Nacelles implemented an efficiency-based industrial organization (automated lines and innovative inspection systems), based on its own production resources as well as on components supplied by a rigorously selected international supply chain. 

One of Safran Nacelles’ operational partners is Middle Rivers Aerostructure Systems (ST Engineering), which supply the transcowl and the thrust reverser cascades (both manufactured in composite materials), the thrust reverser actuation system and the engine build up (EBU), as well as the nacelle integration operation on the LEAP-1A engine.

Integration and after-sales support

Painting, nacelle integration on the engine and final assembly line support

All nacelle components (air inlet, fan cowl, thrust reverser, nozzle and EBU*) are assembled on the engine at Safran Nacelles’ integration site in Toulouse (France). This is where the last adjustment operations between the nacelle, the engine and the mast that will connect the propulsion system under the aircraft wing are carried out, as well as painting in the airline livery. The airlines then take delivery of the propulsion systems before they are installed at the Airbus Final Assembly Line (FAL) where support is provided by Safran Nacelles’ teams.

*EBU: Engine Build Up, regroups several items: electric harnesses, pipes, circulation valves, air inlet anti-icing system, electrical feed, etc.
