performance. Some engine components, accessories and parts, and also its
control systems will be replaced with their analogues made in USA, France,
Germany and Sweden. Modular design, high commonality, turbofan, bypass, two-
shaft, mixed flow with a thrust reverser in a fan duct and silencing system.
最后一句话中的"in a fan duct and silencing system" 是修饰mixed flow with a

排气的尾喷管也消音，比如菊花瓣形
