The CFM Rise engine demonstrator from Safran is making progress. Although launched in 2019, it was publicly revealed in 2021. With the inauguration of a test bench in Belgium, Safran presented its low-pressure compressor, a precursor to the engine’s commissioning. This project, developed in collaboration with GE Aerospace within CFM International, replaces the current Leap, which largely equips the Airbus A320neo and Boeing 737 MAX. This new engine promises a reduction in fuel consumption of 20%. The CFM Rise, an uncovered engine with large visible propellers, represents more than half of Safran’s R&D spending. Full assembly is scheduled for 2025, ground testing in 2026, and flight in 2027, with an anticipated entry into service around 2035.
The Beginning of the CFM Rise Program
The ambitious project by Safran named CFM Rise, a revolutionary initiative in aircraft engines, was realized for the first time at the end of 2021. Although in development since 2019, it is only recently that the demonstrator began to show its first parts. During the inauguration of a new test bench in Belgium, Safran presented the low-pressure compressor, that is, the front part of the engine. This infrastructure marks a significant technological advancement for the development of tomorrow’s engine.
International Partnership and Technological Innovations
Jointly developed by Safran and the American company GE Aerospace, under their joint entity CFM International, the CFM Rise engine is designed to succeed the current Leap engine. It is distinguished by its innovative, uncovered architecture, featuring large visible propellers. This unprecedented technological choice illustrates the partners’ commitment to providing sustainable and effective solutions, aiming for a 20% reduction in fuel consumption. Representing a major part of Safran’s R&D expenditure for the period 2024-2028, CFM Rise is part of a disruptive dynamic with commissioning expected around 2035.
Future Perspectives and Timeline
Aerospace giants Airbus and Boeing are considering the integration of this new engine for their future programs with an entry into service around 2035. Safran plans to complete the assembly of a full prototype of the CFM Rise by 2025, followed by ground tests in 2026. Flight is projected for the following year, marking a crucial step in the development of ever-more efficient and ecological powertrains.
