大型商用飞机发动机市场由GE、普惠和罗-罗三大发动机公司垄断,他们之间的竟争激烈,普惠公司在这一市场竞争中的实力有所削弱。GE公司在支线飞机动力市场竞争中处于优势,该公司的CF34取得了较多市场份额。涡桨发动机虽然在民用飞机动力市场的份额正在减少,但在军用教练机上仍有一定的市场。普惠公司的F119已投入小批量生产,F135也已被选用作JSF的动力
The large-scale commercial aircraft engine market was monopolized by GE, Pratt & Whitney and Luo-Ro, the three major engine companies, and the competition between them was fierce. Pratt & Whitney’s strength in this market competition has been weakened. GE has an advantage in the regional aircraft power market competition. The company’s CF34 has gained more market share. Although the share of turboprop engines in the civil aircraft power market is decreasing, there is still a certain market for military trainers. Pratt & Whitney’s F119 has been put into small-batch production, and F135 has also been selected as a power source for JSF
