METHOD OF CONTROL OF AIR FLOW RATE OF CENTRIFUGAL COMPRESSOR AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2005 - IPC

FIELD: centrifugal compressors with air flow rate control systems; gas-turbine engines for transport facilities and gas-turbine power plants.

SUBSTANCE: proposed method is used for centrifugal compressor having impeller, radial open diffuser and radial vaned diffuser. Proposed method includes change of flow area at impeller outlet before inlet of radial vaned impeller. Besides that, flow area behind radial vaned diffuser is changed additionally; control of flow section before radial vaned diffuser and behind radial vaned diffuser is effected in turn.

EFFECT: extended field of steady operation of compressor.
