Said hydraulic turbine includes a wheel which is made to rotate about a rotational axis (X) by a main water stream (F) going from a penstock to a suction tube along a flow path that passes through the wheel. Said turbine also includes first means that are placed outside the flow path of the main water stream (F) and enable the mixing of a secondary water stream (F), taken from the flow path and located upstream from the wheel, and an oxygen-containing gas (A). Said turbine also includes second means for injection, downstream from the wheel of the turbine, a water/gas mixture (F) produced in the first means.

Hydraulic turbine, and power conversion facility including such a turbine

A propeller for a hydraulic machine includes a hub extending along an axis of rotation of the propeller and vanes extending from the hub and wherein the propeller is formed of several sectors each including a body having a vane attached thereto and wherein the sectors are assembled together by at least one shrunk-on ring which is placed around the bodies. Each sector also includes a side wall and a projection attached to the side wall and which protrudes toward an inside of the hub perpendicularly to the axis (X-X) and wherein at least one washer is connected to the projections inside the hub.
