FIELD: mechanical engineering; compressors.
SUBSTANCE: invention relates to axial-flow compressors and it can be used in different industries. According to invention, two impellers are installed for rotation in opposite directions coaxially in compressor housing. Carrying disks of impellers are made in form of coaxial rings with fitted-on blades to form coaxially arranged stages successively connected by channels.
EFFECT: provision of high efficiency, reduced overall axial dimensions and mass of compressor.
