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 和
In the 1990s, with the demand and development of regional aircraft, the four major western engine companies have been involved in the development of a new generation of regional aircraft engines. They have transplanted many new technologies on large military and civilian engines to regional aircraft engines. This has greatly promoted the development of regional aircraft engines, but it has also made limited market competition even fiercer. The main characteristics of the development of regional aircraft engines in the 1990s are intensified in market competition. The high research and development costs of aircraft engines, the high risks, and the increasingly fierce market competition have made international cooperation an important means for the development of civilian engines. Trunk passenger aircraft engines such as V2500, CFM56 and
