Aerating system for hydraulic turbine

摘要

Aerating system (100) for the runner (10) of a hydraulic turbine, the runner (10) comprising a plurality of blades (2), such that inter-blade canals (11) are configured between each pair of blades (2) for the admission of air in the water flow circulating through the hydraulic turbine, such that the aerating system (100) comprises at least one hydrofoil (12) located in the inter-blade canal (11) of the runner (10) contacting the pair of blades (2) configuring the inter-blade canal (11) where the hydrofoil (12) is located, such that the hydrofoil (12) has a non-axis symmetrical profile, and such that at least one of the blades (2) in contact with the hydrofoil (12) comprises an aerating canal (20) delivering air to the hydrofoil (12).
