10月26日,GE航空集团完成了第1000台GEnx发动机的总装工作。自首台GEnx发动机于2011年投入运营以来,该型发动机已累积了500万飞行小时和90万个飞行循环。GE一直在持续改进GEnx发动机,今年以来,已经在GEnx验证机上测试了多项新技术,包括高压涡轮(HPT)和燃烧室的陶瓷基复合材料(CMC)部件、采用先进冷却技术的新一代高压涡轮一级叶片、采用3D增材制造方法制造的轻型低压涡轮钛铝合金
On October 26, GE Aviation completed the final assembly of the 1000th GEnx engine. Since the launch of the first GEnx engine in 2011, the engine has accumulated 5 million flight hours and 900,000 flight cycles. GE has been continuously improving the GEnx engine and has tested a number of new technologies on the GEnx validator this year, including ceramic matrix composite (CMC) components for high pressure turbines (HPTs) and combustion chambers, a new generation of high pressure with advanced cooling technology Turbine-grade blades, lightweight low-pressure turbine titanium-aluminum alloy manufactured using 3D additive manufacturing methods
