  • Method of regulating multistage axial compressor output and an axial compressor for carrying same into effect
    Patent number: 4147473
    Abstract: A method of regulating the output of a multistage axial compressor having two coaxial rotors in series. The regulation of the compressor output is effected by varying the head of the medium to be compressed, the variation of the head of the medium being effected, after the medium leaves the stator, by changing the rotational speed of the first rotor, the speed of the second rotor being kept constant. The first rotor is connected to a variable-speed drive motor and the second rotor is connected to a constant-speed drive motor.
