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。

This thesis investigated transonic cascade of a certain compressor in order to increase the static pressure ratio of the cascade and reduce the coefficient of the cascade losses.
本课题以某型压气机的跨音速叶栅为研究平台，以提高叶栅静压增压比，减少叶栅流动损失为目标。

At the same time, from the energy consumption perspective, the user more not concerned with the air compressor shaft power energy consumption, but the input power than the energy consumption ratio.
