FIELD: axial compressors, namely, systems for protection from various external influences on blades of compressor, has most use in gas-turbine engines.
SUBSTANCE: in axial compressor of gas-turbine engine, containing rotor with working blades and stator with blades of guiding machines, in immobile part of profile of each blade along its whole length through apertures are made in each rib, inside which a rod is held on external and internal circular rings. Rod in nose immobile part of profile of each blade of input guiding machine is made hollow, input into hollow of which is connected to cavity of hollow input cowl of compressor, and output is connected to through part of compressor.
EFFECT: increased reliability of compressor operation with simultaneously decreased probability of detection by radio-locators on the side of front hemisphere of engine.
