发动机制造商面临新机遇、新挑战 浅谈90年代的支线飞机发动机

Talking about Regional and Business Aircraft' s Engines in 1990s

进入90年代,伴随支线飞机的需求与发展,西方四大发动机公司已卷入新一代支线飞机发动机的研制行列。他们将大型军民用发动机上的许多新技术移植到支线飞机发动机上,这大大促进了支线飞机发动机的发展,但也使有限的市场竞争更为激烈。90年代的支线飞机发动机发展的主要特点市场竞争加剧航空发动机研制经费高、风险大、市场竟争越来越激烈,促使国际合作成为当前民用发动机发展的一种重要途径。干线客机发动机,如V2500、CFM56

The development tendency of the engines for regional and business aircraft is to develop the engines by means uf the international cooperation , to use widely the turbofan , and to lay emphasis on the reliability and enduranc, and maintainability . The second generation of the regional and business aircraft' s engines continues to use and develop in 1990s . The several smaller thrust turbofans for the less than 30- seat aircraft will enter into service after 1996 . The paper introduces simply the engines to be used for the 100-seat class aircraft .
