Performance of the 19XB 10-stage axial flow compressor

Downing, Richard M., Finger, Harold B.

An investigation has been conducted to determine the performance characteristics of the 10-stage axial-flow compressor for the 19XB jet-propulsion engine. Initial performance data were taken with inlet conditions of 59 degrees F and 14 inches of mercury absolute over a range of speeds from 3400 to 17,000 rpm with interstage instruments installed and with normal air leakage past the rotor rear air seal. The effects of interstage instruments, of air leakage past the rotor rear air seal, and of inlet air conditions were then separately evaluated.
