FIELD: mechanical engineering; gas-turbine engines.
SUBSTANCE: invention relates to compressors of gas-turbine engines, including engines of ground application. Novelty is that in compressor with turnable vanes of guide-vane assemblies and with ring closed spaces on periphery of compressor stator connected through channels with compressor passage part, said ring closed spaces on periphery of compressor stator and turnable vanes of guide-vane assemblies are made alternating.
EFFECT: improved reliability and increased efficiency of compressor by eliminating irregularity of air pressure along circumference at inlet of working blades.
