21世纪初,无论是在波音777客机上使用多年的PW4084、GE90、TRENT800发动机、在A380客机上使用不久的GP7000与TRENT900发动机,还是为波音787客机正在研制的GEnx与TRENT1000发动机,在耗油率、全寿命费用、污染物排放、噪声排放、可靠性与安全性等方面都已经取得了显著的进步。为了应对日益激烈的市场竞争和愈发严格的环保要求,美国与欧盟国家确定了大飞机发动机的未来发展目标。
At the beginning of the 21st century, both the PW4084, GE90 and TRENT800 engines used on the Boeing 777, the GP7000 and TRENT900 engines on the A380, or the GEnx and TRENT1000 engines being developed for the Boeing 787 at the fuel economy , Life-cycle costs, pollutant emissions, noise emissions, reliability and safety have made significant progress. In order to cope with the increasingly fierce market competition and the increasingly strict environmental protection requirements, the United States and the European Union countries have set the goal of the future development of large aircraft engines.
