FIELD: engines and pumps.
SUBSTANCE: invention relates to compressor production and can be used in, for example, gas turbine plants incorporating axial multi-stage compressors. The proposed method comprises injecting water into, at least, two compression stages that allows maximum increase in efficiency of the axial multi-stage compressor along with minimum water flow rate. The above effect is provided for by a mathematical expression to calculate the compressor efficiency that allows for steam content and steam enthalpy in air behind the compressor, and to calculate the optimum amount of water injected into the compressor stages required for the said increase at preliminary stages of compressor operation.
EFFECT: higher efficiency.
