目前，正在研制中的商用发动机主要有 ＧＥ９０—１１ ５Ｂ、 ＧＰ７０００、遄达 ９００和ＰＷ８０００等，这些发动机将在近期投入使用。展望末来，商用客机发动机的发展将由传统的降低油耗、减轻重量和增加推力转向保护环境和降低成本，为此，新技术研究和技术计划的制订都围绕这两个目标进行
At present, the commercial engines under development are mainly GE90-11 5B, GP7000, Trent 900 and PW8000, etc. These engines will be put into operation in the near future. Looking forward, the development of commercial airliner engines will shift from traditional fuel economy reduction, weight reduction and thrust enhancement to environmental protection and cost reduction. Therefore, the development of new technology research and technology programs are all based on these two objectives
