GE9X是GE航空专门为波音777X开发的高涵道比涡扇发动机，首次发动机测试于2016年3月进行，并于2018年3月13日首飞。单击此处获取更详细的GE9X开发时间表。

The General Electric GE9X is a high-bypass turbofan developed by GE Aviation exclusively for the Boeing 777X. The first engine test took place in March 2016 and it first flew on March 13, 2018. Click here to get a more detailed timeline of the GE9X development.

GE9X以GEnx和Leap发动机的技术为基础，采用全新的核心机、第四代复合材料叶片和复合材料风扇外壳。该发动机还由300多个增材制造零件和先进材料制成，例如五个陶瓷基复合材料（CMC）部件，包括第一级高压涡轮上的罩环喷嘴、第一、二级涡轮导向器叶片，以及燃烧器的内衬和外衬等。

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.
