FIELD: machine building.
SUBSTANCE: group of inventions relates to turbomachines. Impeller (1) of turbomachine comprises hub (3) having axis (A-A) of rotation, covering disc (13), blades (5; 5A, 5B), located between hub (3) and covering disc (13), and flow channels (11). Each channel (11) is limited by hub (3) covering disk (13) and adjacent working blades (5; 5A, 5B) and has inlet and outlet. Each flow channel (11) passes inside in radial direction from its inlet in direction of the most internal in radial direction part of the specified channel and from the specified most internal in radial direction part to output of the specified channel.
EFFECT: inventions are aimed at reduction of oscillation amplitudes at approach to critical speed and increase in stiffness of rotor.
