Abstract: A method is disclosed for manufacturing a rotating part which belongs to a hydraulic machine of an installation for converting hydraulic energy into electrical or mechanical energy. This rotating part includes blades distributed about an axis of rotation of the rotating part and extending from a leading edge to a trailing edge. This method can include manufacturing, in steel, a first part of each blade, which defines the leading edge thereof, manufacturing a second part of the blade in a material other than steel and attaching this to the first part of the blade so as to form a trailing edge.

Abstract: When traversed by a flow of water, a hydraulic machine rotating part rotates around an axis of rotation. It includes runners which are distributed around the axis of rotation and each extend between a leading edge and a trailing edge. Each runner can include a first part which defines its leading edge and a second part which is attached to the first part and defines the trailing edge at least in part. The second part can be elastically deformable or displaceable in a reversible manner with respect to the first part, under the action of the flow of water, the second part defining, when the machine operates, the direction of the flow of water downstream of the runner.

Abstract: Said hydraulic turbine includes a wheel which is made to rotate about a rotational axis (X2) by a main water stream (F1) 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 (F1) and enable the mixing of a secondary water stream (F2), taken from the flow path and located upstream from the wheel, and an oxygen-containing gas (A2). Said turbine also includes second means for injection, downstream from the wheel of the turbine, a water/gas mixture (F3) produced in the first means.

Abstract: Aerating system for the runner of a hydraulic turbine, the runner comprising a plurality of blades, such that inter-blade canals are configured between each pair of blades for the admission of air in the water flow circulating through the hydraulic turbine, such that the aerating system comprises at least one hydrofoil located in the inter-blade canal of the runner contacting the pair of blades configuring the inter-blade canal where the hydrofoil is located, such that the hydrofoil has a non-axis symmetrical profile, and such that at least one of the blades in contact with the hydrofoil comprises an aerating canal delivering air to the hydrofoil.
