  • Patent number: 10907609
    Abstract: An apparatus for modifying the geometry of at least one part of a turbine can include a shell assembly 3 that includes an outer shell that is shaped to modify the shape of a pre-existing element of a turbine. The outer shell 8 of the shell assembly 3 can be composed of a fiber-reinforced polymeric material and can at least partially define an inner cavity. The outer shell 8 can be bonded to a structure to modify the geometrical shape of that structure. Thereafter, a polymer casting 12 can be injected into the inner cavity via at least one injection port attached to the shell assembly. In some embodiments, one or more stiffeners 9 and/or a core 10 can be positioned within the inner cavity to help improve the bonding of the polymer casting 12 to the shell 2 and/or improve a structural property of the apparatus.

  • Patent number: 10323620
    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.

  • Patent number: 10215151
    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.

  • Patent number: 9291145
    Abstract: 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.
