Advancing the next generation of open-fan and hybrid electric commercial aircraft engine technologies



GE Aviation and Safran have made a decisive announcement for the two aerospace companies: the CFM RISE (Revolutionary Innovation for Sustainable Engines) technology demonstration program.

The RISE program aims to reduce fuel consumption and CO2 emissions by more than 20% compared to current engines and will demonstrate and develop a range of disruptive new technologies for future engines that could enter service by the middle. of the 2030s.

The engine‘s peak propulsive efficiency is at the heart of the program, including the development of an open fan architecture. This is a key component of dramatically improving fuel efficiency while providing the same speed and cabin experience as today’s single-aisle aircraft. The program will also use hybrid electric capacity to optimize engine efficiency while enabling the electrification of many aircraft systems.

In addition, engine technologies developed under the CFM RISE program will be fuel flexible, compatible with Sustainable Aviation Fuel (SAF) and Liquid Hydrogen Fuel.

With the RISE program, the historic partnership between GE and Safran CFM International * will continue to be the leader in propelling commercial aviation by meeting the challenge of sustainable development.

This is good news for Middle Eastern airlines looking for innovative ways to meet their environmental commitments in partnership with GE, such as Etihad Airways’ Greenliner program.

The GE and Safran technology roadmap outlined in the RISE program also calls for further improvements in composite fan blades, heat-resistant metal alloys, ceramic matrix composites (CMCs) and additive manufacturing.

Demonstration engines are expected to begin testing at GE and Safran facilities around the middle of this decade, with flight tests shortly after.

By improving engine efficiency, GE Aviation supports the global market the objectives of the aviation industry to reduce CO2 emissions 50% by 2050 compared to 2019 levels.

Speaking at Aviation Week’s MRO Middle East show held earlier this month at the Dubai World Trade Center, Ram Mulik, general manager of GE Aviation’s customer support and product operations for the Middle -East and Africa, also discussed the tools available now to help reduce CO2 emissions from the existing fleet of aircraft engines.

GE Digital has developed a number of software applications to help aircraft operators reduce emissions and improve operational efficiency. Fuel Insight helps airlines identify areas where they can improve fuel efficiency, while Airspace Insight offers flight path design and maintenance to help aircraft operators ensure routes are designed in the right way. optimal to minimize time, fuel and carbon emissions. FlightPulse® is a mobile application that shows pilots their individual operational efficiency metrics and trends, valuable information that can help them make better decisions and reduce risk and fuel consumption.

GE 360 Foam Cleaner is a proprietary engine cleaning solution that removes dust and dirt particles from the engine. When testing technology in hot and harsh environments, the 360 ​​Foam Wash solution has enabled customers such as Emirates, Etihad Airways, Royal Jordanian Airlines and Qatar Airways to improve engine performance. Reducing deposit build-up in the engine resulted in lower engine exhaust temperatures and improved engine compressor efficiency. These improvements have reduced fuel consumption and increased engine flight time.

Today, all GE Aviation and CFM International engines can operate with the approved SAF. SAF has a lower carbon footprint than petroleum-based fuels because they come from more sustainable sources, such as cooking oil, vegetable oils, municipal waste, waste gases and agricultural residues. The level of CO2 emissions generated by the consumption of jet fuel, based on a life cycle analysis, can be up to 80% lower with SAF than Jet A or Jet A-1.

Even as the aviation industry lobbies for wider adoption and availability of currently approved SAF channels, GE Aviation experts set themselves a new challenge: A future SAF which does not require any mixing with petroleum.
