BIROTATING COMPRESSOR Russian patent published in 2017 - IPC F04D17/00 

FIELD: machine engineering.

SUBSTANCE: birotating compressor comprises a compressor stage mounted with individual supports rotating impellers, comprising wheels with rim and blade rows formed with a twist of the pen blades adjacent crowns in opposite directions, the means of rotation adjacent rotor wheels in opposite directions, the body with a fixed therein stable axis. Means of rotating impellers are made independent of each other and consisting of a stator assembly of the motor, placed on the fixed axis, and a rotary motor unit housed on the rim and/or drive the impeller, wherein at least the stator and/or rotor assembly motor are capable of connecting to a separate power source and arranged relative to each other with the possibility of magnetic interaction between them.

EFFECT: provision of opportunities independent control of frequency of rotation of each impeller to increase reserves dynamic stability of the compressor.
