Abstract: An apparatus is provided for modifying the geometry of at least one part of a turbine, which can include a shell assembly that includes an outer shell that is shaped to modify the shape of a pre-existing element of a turbine. The outer shell of the shell assembly can be composed of a fiber-reinforced polymeric material and can at least partially define an inner cavity. The outer shell can be bonded to a structure to modify the geometrical shape of that structure. Thereafter, a polymer casting 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 and/or a core can be positioned within the inner cavity to help improve the bonding of the polymer casting to the shell and/or improve a structural property of the apparatus.

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.
