bypass ratio

基本解释

Ceramic composites, nanotechnology and shape memory alloys figure prominently in the airframe and ultra high bypass ratio propulsion system construction.
陶瓷合成材料、纳米技术和外形记忆合金卓越地体现于其机体和超高涵道比的推进系统结构。
The results of calculation show that the adjusting of low-pressure turbine and mixer has a remarkable effect on the performance of engine and bypass ratio.
计算结果表明，低压涡轮和混合器的调节对发动机的性能和涵道比的影响尤为显著；
In a reversal of current design trends the MIT concept increases the bypass ratio by minimizing expansion of the overall diameter of the engine and shrinking the diameter of the jet exhaust instead.
与现行设计趋势相反，麻省的概念通过最小化发动机总体直径的尺度以及相应缩小喷气排放直径来增加涵道比。

the ratio of the amount of air that bypasses the combustion chambers of an aircraft gas turbine to that passing through them
