摘要
美国GE和普惠公司及英国罗-罗公司于70年代初期成功地研制了用于干线客机的高涵道比涡扇发动机后,在近20多年里又为这种飞机研制了各种推力级的发动机。目前这三家公司仍控制着干线客机发动机市场,并正竞争研制新的发动机。干线客机及其对发动机的要求现代先进干线客机这种干线客机指目前已在航线上服役、能满足有关噪声、排放物严格限制并能在今后10～20年内还可继续使用的大型客机。由于航空运输量每年以较大的增长率急剧增加,全球需求的飞机量日益加多,同时由于市场竞争形势所逼,促使飞机制造集团纷纷推出各种型号。
The GE Aircraft Engine, Pratt & Whitney and Rolls-Royce successfully developed respectively the CF6, JT9D and RB211 high bypass ratio turbofan in the early 1970s. Since then the companies and their pals again developed the different thrust class engines such as the CFM56, V2500, CF6-80C2, GE90, PW2000, PW4000, RB211-S35E4, Trent 700/800 etc. to meet the requirements of a variety of new trunk aircraft. Now the companies is planning to develop the Trent 900 and GP7000 engines for the 747-500X/-600X and A3XX aircraft. The paper describes the developing status and design features above the engines.
