GE Aviation and Safran launch advanced programme for sustainable engines

The CFM RISE programme by GE Aviation and Safran aims to drive revolutionary innovation for sustainable engines

The CFM RISE (Revolutionary Innovation for Sustainable Engines) programme will demonstrate and mature a range of new, disruptive technologies for future engines that could enter service by the mid-2030s.

The companies today 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.

“The relationship between GE and Safran today is the strongest it has ever been,” said John Slattery, president and CEO of GE Aviation. “Together, through the RISE technology demonstration programme, we are reinventing the future of flight, bringing an advanced suite of revolutionary technologies to market that will take the next generation of single-aisle aircraft to a new level of fuel efficiency and reduced emissions. We fully embrace the sustainability imperative. As we have always done in the past, we will deliver for the future.”

"Our industry is in the midst of the most challenging times we have ever faced,” said Olivier Andriès, CEO of Safran. “We have to act now to accelerate our efforts to reduce our impact on the environment. Through the extension of our CFM partnership to 2050, we are today reaffirming our commitment to work together as technology leaders to help our industry meet the urgent climate challenges.”

Technologies matured as part of the RISE Programme will serve as the foundation for the next generation CFM engine that could be available by the mid-2030s. The programme goals include reducing fuel consumption and CO2 emissions by more than 20 per cent compared to today’s most efficient engines, as well as ensuring 100 per cent compatibility with alternative energy sources such as sustainable aviation fuels and hydrogen.

Central to the programme 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 programme will also use hybrid electric capability to optimise engine efficiency while enabling electrification of many aircraft systems.

The programme is being led by a joint GE/Safran engineering team that has laid out a comprehensive technology roadmap including composite fan blades, heat resistant metal alloys, ceramic matrix composites (CMCs), hybrid electric capability, and additive manufacturing.

The RISE programme includes more than 300 separate component, module, and full engine builds. A demonstrator engine is scheduled to begin testing at GE and Safran facilities around the middle of this decade and flight test soon thereafter.

The original 1974 framework agreement creating CFM International as a 50/50 joint venture between the two aircraft engine manufacturers redefined international co-operation and helped change the course of commercial aviation.

The partnership was renewed in 2008 for the launch of the LEAP engine programme. Today, CFM is the world's leading supplier of commercial aircraft engines with a product line that serves as the industry benchmark for efficiency, reliability, and low overall cost of ownership. More than 35,000 CFM engines have been delivered to more than 600 operators around the globe, accumulating more than one billion flight hours.

Safran is an international high-tech group, operating in the aviation, defense, and space markets. It has a global presence, with 79,000 employees and sales of €16.5 billion ($19.7 billion) in 2020. Safran undertakes research and development programmes to maintain the environmental priorities of its R&T and Innovation roadmap.

GE Aviation, an operating unit of American tech giant GE, is a world-leading provider of jet engines, components, and systems for commercial and military aircraft. GE Aviation has a global service network to support these offerings.
