IMPROVED TURBINE AND BLADE TO PROTECT BLADE ROOT FROM HOT GASES FROM FLOW CHANNEL Russian patent published in 2023 - IPC F01D11/00 

Abstract RU 2809677 C1

FIELD: turbine.

SUBSTANCE: turbine (14), in particular a low-pressure turbine, is described, comprising a plurality of rotor elements (2) and separators configured to be placed between the rotor elements and prevent the penetration of the gas flow from the passage (F) for the passage of the hot gas flow into the internal space (5) of the wheel. Each rotor element includes a deflector (8). A deflector is placed in line with each separator and it deflects the intruded gas flow towards the upper surface of the separator, thereby preventing the blade roots (4) from heating.

EFFECT: improved turbine design is proposed.
