压气机设计点处，流量为66.83kg/s，等熵效率为88.83%，增压比为2.37。可知该设计的压气机效率未达到90%，压比高于设计要求的2.1，可能造成压气机功耗增加。此外，该压气机的设计点靠近喘振点，流量波动极易导致压气机的效率迅速下降。因此，该压气机需要进一步的优化。

At the design point of the compressor, the flow rate is 66.83kg/s, the isentropic efficiency is 88.83%, and the pressurization ratio is 2.37. It can be seen that the compressor efficiency of this design does not reach 90%, and the pressure ratio is higher than the 2.1 required by the design, which may cause the compressor power consumption to increase. In addition, the design point of the compressor is close to the surge point, and the flow fluctuation can easily lead to the rapid decline of the compressor efficiency. Therefore, the compressor needs further optimization.
