bypass engine

However, the approaches in developing high bypass ratio engine and low bypass ratio engine are different.

但是, 在核心机基础上研制大涵道比涡扇发动机和小涵道比加力涡扇发动机的技术途径是不同的.

The results show that a turbofan engine with a small bypass ratio must be installed, and a suitable turbine entry temperature is obtained by optimization with life cycle cost.

结果表明宜采用小涵道比涡扇发动机，而且不考虑费用时涡轮前温度取值越高越好，考虑费用时则有最大值；

Therefrom some conclusions are obtained as: 1.The system's bypass ratio must be actively controlled by adjusting both core and bypass engine's through flow areas.

得到：（1）其必为变涵道比循环系统，由可变几何内、外涵通道提供对涵道比的主动控制；
