A giant LEAP forward
Never before has an aircraft engine sparked such enthusiasm as LEAP. This new-generation engine, developed by Safran and GE Aviation through CFM International is now challenging its manufacturers with an unprecedented ramp-up in production.
LEAP (Leading Edge Aviation Propulsion) is the well-deserved name for a new engine that represents a major technological advance and is setting the aerospace industry on fire.
At a time when all eyes are turned to environ-mental issues, the LEAP engine is providing operators with a 15 percent reduction in fuel consumption and CO2 emissions as well as a 50 percent reduction of NOx emissions compared to the CFM56 engine. The CFM56 is the world’s best-selling aircraft engine with more than 29,000 engines delivered to date, powering single-aisle airplanes for more than 550 operators worldwide. The LEAP engine also reaches 99.98 percent dispatch reliability and complies with the tightest noise emission requirements, and it retains the reliability and low maintenance costs of the CFM56.
LEAP was designed entirely from scratch, a rare occurrence in aeronautics. As a fully-fledged innovation, it has created enormous enthusiasm amongst all who have worked for several years on the project.
“Our suppliers do play a major role in satisfying the requirements of the three keystones of operational performance – quality, delivery and cost”, says Hélène Moreau-Leroy, First circle SKF sponsor and former CEO of Safran Transmission Systems. She has lived this industrial adventure to the full, working in close partnership with the SKF Aerospace Business Unit teams.
“In 2014, Safran initiated the inner circle approach in order to build a very close partnership with a selected group of its main suppliers,” says Moreau-Leroy. “Within this circle, SKF is the only supplier of engine mainshaft bearings and transmission bearings.”
Safran is listed on Euronext Paris and is part of the CAC40 index, as well as the Euro Stoxx 50 European index.
In February 2018 Safran took control of Zodiac Aerospace, significantly expanding its aircraft equipment activities. Hélène Moreau-Leroy, First circle SKF sponsor and former CEO of Safran Transmission Systems, has been appointed director of the Zodiac integration project.
Confidence is at the centre of the relationship with the inner circle suppliers. “In order to achieve performance, we must explain to them how our needs are evolving,” says Moreau-Leroy.
Manufacturers such as SKF are able to assure us of their ability to cope with a rise in the production rate.

“Fortunately, key manufacturers are able to assure us that they have the ability to increase their production rate. Indeed, they will be improving their production facilities in the months and years ahead.”
This is exactly what happened in the case of SKF, given the tremendous commercial success of LEAP. “It was a huge challenge,” says Laurent Peinetti, global account manager for the Safran Group at SKF. “In order to enable this rapid step-up in production, we’ve harnessed all our expertise and made high levels of investment. The LEAP programme has led us to totally transform and improve our production facilities.”
As for the future, Safran and SKF are already working jointly on engine projects as far ahead as 2030. These will be even more fuel-efficient, quieter and with a higher level of performance. Beyond that, visions of the future of aeronautics belong in the realm of science fiction.
Aeronautics finds its strength and reliability in day-to-day life.

“The main thing,” says Moreau-Leroy, “is the here and now. Aeronautics finds its strength and reliability in day-to-day life. We carry hundreds of thousands of passengers every day. This must be what determines our way of working. Precision, rigour, operational excellence, the ability to secure all of our activities, our performance – this is what we fundamentally care about at all times.”
