The trials are at ONERA’s wind tunnel facility in Modane, France. This disruptive architecture, a key pillar of the CFM RISE technology demonstration program, [1] is currently the most promising in terms of reducing the environmental footprint of aviation. The Open Fan aims to reduce fuel burn and CO2 emissions by 20% and up to 80% when combined with SAFs or sustainable aviation fuels for the next generation of single-aisle commercial jets by 2035.

To support the process of bringing the Open Fan’s aerodynamics and acoustics to maturity, Safran Aircraft Engines and ONERA recently signed a framework agreement for an ambitious test plan from 2024 to 2028, building on previous trials with the ECOENGInE.

Tests on the ECOENGInE backed by the French Civil Aviation Authority (DGAC) as part of the CORAC[2] plan aim to demonstrate the aerodynamic and acoustic performance of the fan module by simulating real-world airspeeds in a wind tunnel and validate the design of the fan blades. The blades play a key role in the engine’s overall efficiency. In total, over 200 hours of testing will be performed during this campaign, followed by simulation tests with the engine mounted on a demonstrator plane wing section. For these tests, Safran Aircraft Engines benefits from the knowledge and expertise of the ONERA teams and use of the world’s largest sonic wind tunnel. The S1MA tunnel is a unique test facility in terms of size 8 meters across or over 26 ft and airflow speed, making it possible to test engines in isolation or mounted on a wing structure. It therefore plays a crucial role in the development of new propulsion systems for the next generation of planes.

“As scientific experts in aerospace, ONERA is a key player in efforts to reduce the environmental footprint of aviation,” said Marie-José Martinez, Wind Tunnels Director for ONERA. “The partnership we’ve set up with Safran reflects our shared drive to support the development of cleaner, greener aircraft. ONERA is proud to be making available our exceptional facilities, funded by the French government, and our world-renowned engineers and technicians.”

“This series of wind tunnel tests is a major milestone in our Research & Technology roadmap, which aims to develop the technological building blocks for the next breed of commercial jet engines,” said Pierre Cottenceau, VP Engineering and R&T for Safran Aircraft Engines. “With the RISE program, Safran Aircraft Engines is contributing our long-standing expertise to the development of the fan module to demonstrate the benefits of an unshrouded engine architecture on the ground and in flight by mid-decade.”

The company is coordinating demonstration of the Clean Aviation[3] OFELIA project (Open Fan for Environmental Low Impact of Aviation), which involves 26 European partners, including ONERA. Safran is also working on a number of other major technological building blocks in conjunction with the Open Fan architecture, such as hybrid propulsion.

A wide-ranging test program is being rolled out across Safran sites to further the maturity of these technologies, which are key to helping air transport achieve carbon neutrality by 2050. For example, our Villaroche center in France has already completed ingestion tests on Open Fan blades and is currently building a new test stand facility. Operational in 2025, it will boast an 8-meter-wide (26 ft) chamber and will be used to carry out development and certification tests for the RISE program.

[1] The RISE program is being developed by CFM International, a 50/50 joint venture between Safran Aircraft Engines and GE Aerospace.
[2] The Council for French Civil Aerospace Research (CORAC), created in 2008, is the State-Industry consultation body dedicated to the implementation of the national research program for the aerospace industry.
[3] The Clean Aviation Joint Undertaking is the European Union’s leading research and innovation program for transforming aviation toward a sustainable and climate neutral future.

Safran (safran-group.com) is an international high-technology group, operating in the aviation (propulsion, equipment and interiors), defense and space markets. Its core purpose is to contribute to a safer, more sustainable world, where air transport is more environmentally friendly, comfortable and accessible. Safran has a global presence, with 76,800 employees and sales of 15,3 billion euros in 2021 and holds, alone or in partnership, world or regional leadership positions in its core markets. Safran undertakes research and development programs to maintain the environmental priorities of its R&T and innovation roadmap.

Safran is listed on the Euronext Paris stock exchange and is part of the CAC 40 and Euro Stoxx 50 indices.

Safran Aircraft Engines designs, produces and sells, alone or in partnership, commercial and military aircraft engines offering world-class performance. Through CFM International*, Safran Aircraft Engines is the world's leading supplier of engines for single-aisle mainline commercial jets. The company is also fully responsible for the design, development and production of the M88 and M53 engines for the Rafale and Mirage 2000 fighters, respectively, and will be the systems integrator for the engine powering Europe’s New-Generation Fighter.

*CFM International is a 50/50 joint company between Safran Aircraft Engines and GE.

ONERA, the French aerospace research center
ONERA (onera.fr) is the French national laboratory for aeronautics and space R&T, staffed by 2000 people. Under the supervision of the French Ministry of Armed Forces, ONERA has an annual budget of 289 million euros (2023), over half of which comes from study, research and testing contracts. As the French expert in aerospace technologies, ONERA prepares tomorrow's defenses, meets the aerospace challenges of the future, and contributes to the competitiveness of the European aerospace industry. ONERA masters all the disciplines and technologies in its aerospace fields.

All major civil and military aerospace programs in France and Europe contain "DNA" from ONERA: Ariane, Airbus, Falcon, Rafale, missiles, helicopters, engines, radars, etc.
