GE Aviation and Safran have launched a bold technology development program targeting more than 20% lower fuel consumption and CO2 emissions compared to today’s engines. The CFM RISE (Revolutionary Innovation for Sustainable Engines) program will demonstrate and mature a range of new, disruptive technologies for future engines that could enter service by the mid-2030s.
The companies also signed an agreement extending the CFM International 50/50 partnership to the year 2050, declaring their intent to lead the way for more sustainable aviation in line with the industry’s commitment to halve CO2 emissions by 2050.
Technologies matured as part of the RISE program will serve as the foundation for the next-generation CFM engine that could be available by the mid-2030s. The program goals include reducing fuel consumption and CO2 emissions by more than 20% compared to today’s most efficient engines, as well as ensuring 100% compatibility with alternative energy sources such as sustainable aviation fuels (SAFs) and hydrogen.
Central to the program is state-of-the-art propulsive efficiency for the engine, including developing an open fan architecture. This is a key enabler to achieving significantly improved fuel efficiency while delivering the same speed and cabin experience as current single-aisle aircraft. The program will also use hybrid electric capability to optimize engine efficiency while enabling electrification of many aircraft systems.
