CFM has done 100 tests for the RISE program, which includes the development of innovative engine architectures, combustion technology, thermal management, and hybrid electric systems.
CFM International, a leading aircraft engine manufacturer, has announced significant progress in its Revolutionary Innovation for Sustainable Engines (RISE) technology program. The program unveiled two years ago, aims to develop advanced technologies for more sustainable aviation and achieve the industry’s goal of net-zero emissions by 2050. CFM has completed over 100 tests as part of the RISE program, which includes the development of innovative engine architectures, combustion technology, thermal management, and hybrid electric systems.
One of the key advancements made through the RISE program is the open fan architecture, which has demonstrated improved propulsive efficiency and favorable noise level performance. CFM is targeting more than 20% better fuel efficiency and 20% lower CO2 emissions compared to the most efficient engines currently in service. The program also focuses on meeting stringent non-CO2 and noise emission requirements.
“The RISE program was launched as the absolute manifestation of our deep commitment to push the boundaries of innovation and deliver the breakthrough technologies that will help achieve our most aggressive sustainability goals in support of the industry promise of net zero by 2050. Our global team of engineers has been accomplishing amazing things and I am more convinced than ever our RISE program will deliver the propulsion technologies that will set even higher standards for our industry,” said Gaël Méheust, president and CEO, CFM International.
CFM is on track for ground and flight tests of the RISE technologies in the mid-2020s. The company has previously announced plans to collaborate with Airbus for an open fan flight technology demonstration. CFM’s parent companies, GE Aerospace and Safran Aircraft Engines, have allocated over 1,000 engineers globally to support the development of the RISE program.
“Since we launched the RISE program, we made significant progress to validate the conceptual design review and launch the industrialization of the first demonstrator parts. We are on track to the ground and flight tests around the middle of the decade with a thorough test plan that includes open fan aeroacoustics modeling this year. The RISE program is a great opportunity for our engineers to play a key role in building a more sustainable aviation industry,” said Michel Brioude, Vice President Engineering and R&T, Safran Aircraft Engines.
According to Mohamed Ali, vice president of engineering for GE Aerospace, incremental improvements in fuel efficiency will not be sufficient to achieve the industry’s net-zero ambition. He believes that revolutionary technologies are required, and the open fan architecture represents a significant leap in engine efficiency. CFM is committed to proving and maturing these technologies through an extensive testing roadmap.
“The industry can’t reach its net zero ambition by 2050 with status quo incremental improvements in fuel efficiency. Revolutionary technologies are needed. That’s why we believe the time for open fan is now, an advanced engine architecture that could unlock the single greatest jump in generational engine efficiency that CFM has ever achieved. This is supported by our most comprehensive testing roadmap yet to prove out and mature these technologies for the future of flight,” said Mohamed Ali, vice president of engineering, GE Aerospace.
