METHOD OF PROVIDING GAS-DYNAMIC STABILITY OF AXIAL COMPRESSOR Russian patent published in 2024 - IPC F02C9/00 F04D27/00 

FIELD: gas turbine engine building.

SUBSTANCE: invention relates to methods of providing gas-dynamic stability of axial compressors under operating conditions and changing parameters at which their stable operation was initially disturbed. Technical task of the proposed invention is to ensure the stable operation of axial compressors under operating conditions and changing parameters, at which their stable operation was initially disturbed. Technical result is achieved by the fact that in the disclosed method of providing gas-dynamic stability of axial compressors during their operation and changing parameters, the critical stages of the axial compressor are determined, working medium injection points in critical stages of axial compressor are selected, parameters of injected working medium are calculated, parameters of injected working medium are set, moment of working medium blowing is determined; working medium is blown with preset parameters in selected places.

EFFECT: stable operation of axial compressors under operating conditions and variation of parameters at which their stable operation was initially disturbed.
