FIELD: engines and pumps.
SUBSTANCE: invention relates to designs of the gas turbine axial-flow compressors. The novelty of this invention consists in that the axial-flow compressor stage incorporates impeller blades and straightener blades, everyone of which is furnished with anti-vortex ribs arranged crosswise the blade lengthwise axis. Note here that the ribs arranged on the impeller blades are located opposite the straightener blades ribs.
EFFECT: higher efficiency and wider range of the compressor stable operation.
