Compressor having low-pressure and high-pressure compressor operating at optimum ratio between pressure ratios thereof and gas turbine engine adopting the same

摘要

A compressor having a front fan, which rotates to compress intake air, a single-stage low-pressure compressor which is disposed behind the front fan to compress intake air, and a single-stage high-pressure compressor which compresses the compressed air compressed by the low-pressure compressor; a ratio (R_H/R_L) of a pressure ratio (R_H) of the high-pressure compressor to a pressure ratio (R_L) of the low-pressure compressor is within a range of 4.5 to 6.0.
