Building on the GEnx and Leap programs, the GE9X incorporates an all-new core, fourth-generation composite blades and a composite fan case. The engine is also made with more than 300 additively manufactured parts and advanced materials, such as five ceramic matrix composite (CMC) components that include the first-stage shroud and first- and second-stage nozzles on the high-pressure turbine, and the inner and outer linings of the combustor.
