Nacelles de moteur

Safran is one of the world's two leading aircraft engine nacelle producers. We outfit more than 20,800 engines now in service, with nacelles for all types of aircraft: regional jets, business jets, mainline commercial jets (over 100 seats).

An integral part of jet engines, the nacelle optimizes airflows and also protects the engine. It is in fact a complex system that handles several basic functions: noise reduction, aircraft braking and keeping it lined up when landing on slippery runways (via the thrust reversers, integrated in the nacelle).

Building on our technological leadership in composite materials, Safran has been making engine nacelles for some 30 years. They have been chosen for engines deployed by more than 200 airlines, and combine high-performance, light weight, noise attenuation and advanced aerodynamics.

Safran works with the leading manufacturers of both regional and business jets: Sukhoi, Embraer, Dassault, Bombardier, Gulfstream, etc. On mainline commercial jets (over 100 seats), Safran provides nacelles for the two leaders, Airbus and Boeing, all the way up to the Airbus A380 super-jumbo, as well as Comac of China.

A technology standard in the nacelle Market

The Safran-designed nacelles on the A380 set the technology standard in this market. In fact, this was the first aircraft in the world to be fitted with a nacelle featuring an electrical thrust reverser actuation system (ETRAS®), and a nozzle made of advanced titanium alloys. The resulting performance, especially in terms of noise reduction, clearly reflects Safran's commitment to environmental protection.

Building on these advanced technologies, Safran also developed acoustic treatments for nacelles on business and regional jets, such as those on the SaM146 engines powering the Sukhoi Superjet 100 regional jet.

Safran has also developed concepts for the regional and business jet markets, based on two-door thrust reversers that reduce operating costs: PERT® (Planar Exit Rear Target) and Papillon®.


Safran Nacelles: Operating in all segments of the civil aviation market, from business and regional jets to mainline commercial jets, Safran develops complete nacelle systems for their engines, and provides a full slate of support services. In addition, Safran Nacelles makes advanced composites for aerostructures.
