FIELD: machine building.
SUBSTANCE: described is a turbine, and in particular a low-pressure turbine, comprising a plurality of rotor elements and separators arranged between rotor elements and preventing penetration of gas flow from the hot gas flow passage into the inner space of the wheel. Each element of the rotor includes a deflector. Deflector is placed in accordance with each separator, and it deflects blowdown air forced from inner spaces of wheels by rotor elements, to prevent heating of blade roots by gas flow penetrated inside.
EFFECT: improved turbine and blade for protection of blade root from hot gases from flow passage are disclosed.
