Safran Aircraft Engines, previously Snecma (Société nationale d'études et de construction de moteurs d'aviation) or Snecma Moteurs, is a French aerospace engine manufacturer headquartered in

satellites
.

Some of its notable developments, alone or in partnership, include the

CFM56 and CFM-LEAP for single-aisle airliners, as well as the Ariane 5's Vulcain
engine.

The company employs around 15,700 people across 35 production sites, offices, and

MRO facilities worldwide and files an average of nearly 500 patents
each year.

Safran Aircraft Engines also notably operates two joint ventures with GE Aerospace: CFM International, the world’s leading supplier of commercial aircraft engines,[2] and CFM Materials.

Timeline

1946: Initial employees were German engineers, primarily from BMW, located in Decize, France. Group was known as Groupe "O" until 1950. First design product was the ATAR engine.

Major programmes

In terms of volume, the most impactful commercial aero engine produced by Safran Aircraft Engines is the

KC-135 Stratotanker fleet of the United States Air Force, this operator being the engine's biggest customer.[5] Following this turn of fortune, tens of thousands of engines have since been produced over the decades. A total of 30,000 CFM56s have been completed by July 2016.[5]

Safran Aircraft Engines is also the main partner for several other engines coproduced with GE, including the CF6-80 and GE90.[6][7] Safran Aircraft Engines is also involved in the Engine Alliance, which manufactures the GP7000 high-thrust turbofan engine, one of the only two powerplants certified to power the twin-decker Airbus A380.[8][9] During the 2010s, Safran started manufacturing its portion of the LEAP engine via the CFM International joint venture; Safran and GE each assemble half of the annual volume.[10] To cope with high demand for the LEAP engine, CFM has duplicated supply sources for 80% of parts and as well as subdivided assembly sites.[11]

Safran Aircraft Engines is also involved in

NPO Saturn; this company produces SaM146 turbofan engine, which is used to power the Sukhoi Superjet 100 regional jet.[12] During 2005, a new production plant was founded in Rybinsk, VolgAero, to manufacture components of the SaM146; additionally, parts and assemblies of other engines produced by PowerJet's two parent companies are also produced on this site.[13]

In terms of military engines, Safran Aircraft Engines produces the Snecma M88 turbofan. This engine was developed to power the Dassault Rafale fighter aircraft.[14] It fulfills numerous stringent performance criteria, including a high thrust-to-weight ratio, low fuel consumption across all flight regimes, and a long engine life.[15] Additional considerations were afforded to both the M88's maintainability and upgrade potential (73 kN to 105 kN using the same core).[16][17][18] Qualification of the M88-2 engine was completed during 1996 while the first production engine was delivered by the end of that year. It is of a modular design for ease of construction and maintenance, as well as to enable older engines to be retrofitted with improved subsections upon availability, such as existing M88-2s being upgraded to M88-4E standard.[19] In May 2010, a Rafale flew for the first time with the M88-4E engine, an upgraded variant with greater thrust and lower maintenance requirements than the preceding M88-2.[20]

In 2002, the

Industria de Turbo Propulsores.[21][22][23] EPI GmbH is tasked with designing, developing, marketing, manufacturing and providing support for the TP400-D6 turboprop engine to power the Airbus A400M Atlas, a military airlifter manufactured by Airbus Defence and Space.[24][25][23][26] The TP400 is the most powerful turboprop in the world currently in production.[27][28]

During 2008, the

CFM56 turbofans.[29]
With its 30:1
RTM carbon fiber fan blades will be supported by the in-service LEAP experience.[32]

During December 2019, Safran and MTU announced an agreement to found a 50/50 joint venture to manage the development, production, and after-sales support activities of the new military aero engine intended to power the Future Combat Air System.[33]

In June 2021, Safran presented an updated architecture for its RISE open rotor concept, with a single to 144-156 in (365-396 cm) fan with variable pitch blades forward of a row of static guide vanes, to deliver 30,000lb of thrust (133 kN) with 20% better efficiency than the

CFM LEAP.[34]
