HYDRAULIC TURBINE ASSEMBLY AND METHOD TO INSTALL REPLACEABLE HYDRAULIC TURBINE Russian patent published in 2017 - IPC F03B3/12 

FIELD: machine engineering.

SUBSTANCE: hydraulic turbine assembly 50 includes a hub 54 rotatable about a central axis 71 and configured to be installed in water channel and at least three working wheel blades 52. The hub 54 includes an upstream end, a downstream end and an outer surface between the upstream end and the downstream end, and at least three mounting grooves. Each mounting groove comprises a first mounting surface 56 of the hub 54 and a second mounting surface 58 of the hub 54. The surface 58 is located downstream and radially inside from the surface 56. The ascent continues between surfaces 56 and 58. Each of the blades 52 comprises a base 64 configured to be mounted in a one of the corresponding mounting grooves. The base 64 comprises a first mounting surface 68 configured to abut against the surface 56 and a second mounting surface 70 configured to abut against the surface 58.

EFFECT: increase of power generated by the turbine.
