CFM RISE program targets more than 20 percent lower emissions with hydrogen capability in scope.

GE Aviation and Safran, under the name of their joint venture CFM International, launched a bold technology development program of sustainable engines targeting more than 20 percent 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.

Next-generation CFM sustainable engines

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, as well as ensuring 100 percent compatibility with alternative energy sources such as Sustainable Aviation Fuels and hydrogen. Airbus already announced its plans to utilize engines with similar energy sources for future models.

The main objective of the program is to enhance propulsive efficiency for the engine and developing an open fan architecture. This could significantly improve fuel efficiency while delivering the same speed and cabin experience as current single-aisle aircraft.

Roadmap announces technologies like composite fan blades, heat resistant metal alloys and ceramic matrix composites (CMCs). The RISE program includes more than 300 separate component, module and full engine build. A demonstrator engine should begin testing around the middle of this decade and a flight test soon thereafter.

The future of CFM International

Creating CFM International as a joint venture in 1974 between the two manufacturers, changed the course of commercial aviation. The partnership was renewed in 2008 for the launch of the LEAP engine program. Today, CFM is the world’s leading supplier of commercial aircraft engines. Joint venture built more than 35,000 engines for more than 600 operators around the globe.

On 14 June, the companies also signed an agreement extending the 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.
