GE Aviation has named Japan's IHI, Safran units Snecma and Techspace Aero of Belgium, and MTU Aero Engines as participants in the GE9X engine being developed for the Boeing 777X.

Together, the four companies will be responsible for approximately 25% share in the programme.

GE says it has "long-standing relationships" with all four companies. "We look forward to working with these valued partners to deliver new technologies for the most fuel-efficient widebody engine in the world," it adds.

IHI will be responsible for designing and manufacturing components for the low-pressure turbine and fan mid-shaft. The company is a participant in GE's CF34, GE90, GEnx and Passport engine programmes and has been producing GE military engines under licence for more than 60 years, says GE.

France-based Safran will design and manufacture the 3D-woven composite forward fan case and turbine rear frame and work with GE on the composite fan blades through its 50:50 joint venture company CFAN. Safran owns the CFM International joint venture with GE, responsible for the CFM56 and Leap engines for the Boeing 737 and 737 Max. It also participates in the CF6, GE90 and GP7200 programmes.

Techspace Aero will design and make the low-pressure compressor and manufacture the fan disk, while MTU, based in Munich, will be responsible for the turbine centre frame.

The GE9X engine will be in the 100,000lb thrust class and will offer a 10% improvement in fuel burn over the GE90-115B, says GE. Production of the 777X is due to commence in 2017.
