Engine pressure ratio (EPR), the ratio of inlet pressure over exhaust-let pressure measurements. The ratio is used as the primary parameter to set thrust on some engines.
发动机压力比(epr)，进气压力与排气压力值的比，某些发动机以此作为设定推力的主要依据。
For improve thrust loading and decrease fuel consume of the engine, propulsive system of the future demand the compressor in possession of higher pressure ratio and more efficiency.
未来飞机推进系统要求压气机的压比和效率均大大高于目前的使用水平，以提高发动机推重比，减小燃油消耗。
The effects of combustion chamber pressure and mixture ratio on engine performance were analyzed based on simulation.
并根据结果分析了燃烧室压强和混合比对发动机性能的影响。
