涵道比 meaning in English
bypass ratio
Examples
- By adjusting many variable geometry components of the engine , bypass ratio can be changed during large range ( the most 0 . 25 of military fighter ) . the high specific thrust characteristic of turbojet engine and the low specific fuel consumption characteristic of the turbofan engine can be realized during different flight phase by the usage of vce technology
变几何变循环发动机是应用于第四代多用途战斗机的理想动力装置，通过多个部件几何的调节在较大范围内改变涵道比，能够使发动机在不同航段分别实现涡喷发动机的高单位推力性能和涡扇发动机的低油耗性能。 - These variable geometry components include high pressure - compressor , high - pressure turbine , low - pressure turbine , inlet area ratio of mixer and main nozzle throat area . 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；在其它部件几何结构不同时，单个部件几何调节后，发动机性能的变化趋势是不同的。
