Playing a key role in aviation’s push to achieve net zero CO2 emissions by 2050, CFM International’s Revolutionary Innovation for Sustainable Engines (RISE) program — which is developing open-fan engine architecture for the industry’s next-generation engines — remains on track to start ground and flight tests in the middle of this decade, GE Aerospace, part of the CFM joint venture with Safran Aircraft Engines, confirms to Runway Girl Network.
Launched in 2021, the RISE program aims to reduce fuel consumption and CO2 emissions by more than 20 percent compared to today’s engines, as well as ensure compatibility with alternative energy sources like Sustainable Aviation Fuels (SAF) and hydrogen to provide even further sustainability benefits.
Central to the program, the open-fan architecture — also known as an “unducted fan” which is being matured as part of RISE — is expected to serve as the foundation for the next generation CFM engine that could be available by the mid-2030s.
Work is well underway. With more than 100 tests on CFM RISE already completed, a GE Aerospace spokeswoman told RGN in advance of the New Year that: “This puts the program on track for ground and flight tests in the middle of this decade.”
