涡轮风扇发动机减推力起飞必要性分析

Necessity Analysis of Reduced-Thrust Taking-off of Turbofan Engines

减推力起飞(也称灵活推力起飞)是目前大型、重型民航飞机较为常见的起飞方式。在飞行条件允许的情况下,采用减推力起飞可降低航空公司的运行成本,大大提高发动机使用寿命,有效降低发动机空中停车率,对确保飞行安全具有重要意义。

Reduced-thrust taking-off(also called flexible-thrust taking-off) is commonly used in transportation aircrafts' taking-offs in civil aviation flights. If conditions permit,the reduced-thrust taking-off can lower the cost for the airlines,and prolong the engines' service life. It can also reduce the in-flight engine failure rate,which,in turn,will significantly improve the flight safety.
