FIELD: engines and pumps.
SUBSTANCE: proposed hydraulic turbine comprises cylindrical section-modular housing 1 with vane-screw rigidly fixed on the shaft and appliance to secure the vanes to the housing that allows the shaft rotation. Each section accommodates vane-screw. All vanes feature identical curvature to provide for constant flow rate and synchronous operation of all vane-screws. Attachment mechanism is arranged on opposite side of vane-screw relative to flow direction. Turbine incorporates flow stabilisers made up of metal sheets with their one rib secured to housing 1 and their plane oriented along the radius towards the shaft along housing 1 to stabilise the flow coming from one vane-screw to the other.
EFFECT: simple design and operation, higher output and efficiency, longer life, reduced production costs.
