FIELD: turbine building.
SUBSTANCE: proposed double-flow wheel of turbomachine contains cascade of radial-axial blades pointed by concave surface opposite to flow, cowling with sharp entry edge and cover disks made in form of sectors and installed on pins on blade edges. Cowlings are installed on pins in blade holes. Ports are made on radial sections of blade profiles, at least skipping one blade, and ribs are left for fastening sectors of cover disks and cowlings.
EFFECT: provision of convenient and simple assembling of cover sectors, reliable operation of blades at vibration, reduced areas of friction of radial channel walls.
