French aerospace manufacturer Safran is making progress on testing the low-pressure compressor and composite fan blades for the CFM Rise open fan engine, a next-generation propulsion system designed for greater efficiency and lower emissions. The Rise program, led by CFM International, a joint venture between GE Aerospace and Safran Aircraft Engines, is expected to power aircraft entering service in the mid to late 2030s.
Testing Safran’s Next-Generation Compressor
Safran Aero Boosters has prepared its first high-speed low-pressure compressor, named e-artemis, for testing at an aerodynamic facility in Belgium. The tests will evaluate new designs such as an integrally bladed rotor made from titanium alloys for improved durability and resistance to potential impact. These efforts build on Safran’s experience supplying compressors for engines including the CFM Leap, GEnx, GE9X, and GE Passport.
Fan Blade Development and Expanded Facilities
Safran has also tested three large-diameter composite fan blade configurations to validate performance in mechanical integrity, aerodynamics, and acoustics for unducted environments. To support this work, the company is constructing a new test facility in Villaroche, France, featuring an 8-meter-wide chamber for large-scale component testing, set to open next year.
The Metalnomist Commentary
Safran’s advancement of CFM Rise component testing underscores Europe’s commitment to leading sustainable aviation technology. By combining titanium innovation with composite fan design, the program positions itself as a major step toward fuel efficiency and lower emissions in the global aerospace industry.
