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 percent compared to today’s most efficient engines, as well as ensuring compatibility with alternative energy sources like Sustainable Aviation Fuels (SAF) and hydrogen to provide even further sustainability benefits.
Advancing open fan architectures

Built on proven technologies
Any future CFM engine will be built using the latest technologies.
The pursuit of ever-increasing propulsive efficiency has driven the growth of engine fan diameter in commercial jet engines over the past five decades. This progression is ultimately leading to the open fan concept which is currently the most efficient and sustainable option to improve the propulsive efficiency of the engine. The advanced open fan architecture to be demonstrated as part of the RISE program will fly at the same speed as current single-aisle aircraft (up to Mach 0.8, or 80 percent the speed of sound) with a noise signature that will meet anticipated future regulations.
Foundational technologies will be developed and will form the basis of any future CFM engine:
Carbon fiber composite blades manufactured with a 3-D weaving process enable a larger fan diameter to improve propulsive efficiency
An advanced compact core that will increase thermal efficiency and significantly decrease fuel consumption
Hybrid electric systems
Advanced metal alloys and ceramic matrix composites will also improve thermal efficiency
A 100% compatibility with alternative energy sources as Sustainable Aviation Fuels (SAF) and hydrogen allowing CO2 emissions reduction by 80% will be a key focus of our program.
The technologies developed as part of the RISE program require closer integration with the aircraft manufacturers than ever before. Through a strong partnership with aircraft manufacturers, we can fully optimize installed performance of advanced architectures
The CFM RISE program will be the first to introduce hybrid electric technologies for single-aisle propulsion systems. Engine performance will be optimized by providing additional electric thrust, while also generating electricity both for itself as well as for the aircraft
