Safran Aircraft Engines (previously Snecma) is a French aerospace engine manufacturer headquartered in Courcouronnes, France. It designs, makes and maintains engines for commercial and military aircraft as well as rocket engines for launch vehicles and satellites.
Some of its notable past developments, alone or in partnership, include the M88 for the Rafale, Olympus 593 for Concorde, CFM56/CFM-LEAP for single-aisle airliners, and the Vulcain engines for the Ariane 5.
It has 15,700 employees working at 35 production sites, offices, and MRO facilities worldwide. It files an average of nearly 500 patents each year.
Safran Aircraft Engines is a subsidiary of Safran.
In 2008, the European Commission launched an open rotor demonstration led by Safran within the Clean Sky program with 65 million euros funding over eight years : a demonstrator was assembled in 2015, and ground tested in May 2017 on its open-air test rig in Istres, aiming to reduce fuel consumption and associated CO2 emissions by 30% compared with current CFM56 turbofans. With its 30:1 bypass ratio, it should deliver a 15% improvement over the CFM International LEAP already at 11:1; but Airbus is more interested in the more conventional Ultra High Bypass Ratio (UHBR) turbofan at 15:1, which could be introduced from 2025, offering 5% to 10% better efficiency than the LEAP and to be tested from 2020.
The gearbox and the blade variable-pitch technologies were validated in 100 cycles and 70 hours of tests, including 25% at takeoff thrusts of 21,000-25,000 lbf (93-111 kN), reverse thrust, and rotor imbalance with a blade weight. Afterwards, it was disassembled in April 2018 to examine each part and refine expected wear predictions. GE Aviation was involved through its Italian subsidiary Avio Aero, providing the gearbox and the low-pressure turbine. To be certified, a blade-out event have to be extremely improbable, less than once every billion flight hours as its RTM carbon fiber fan blades will be supported by the in-service LEAP experience.
It was built around the Snecma M88 core, the fan blades are slower than the 1980s GE36 due to the reduction gear, lowering noise and the fan can be mounted at the engine front for under-wing configurations.
Safran Aircraft Engines is also the main partner for the General Electric CF6-80 and GE90 programs. It is also involved in the high-thrust turbofan business as part of the Engine Alliance GP7000 program, which produces one of the only two engines certified to power the Airbus A380.
