FIELD: gas industry.
SUBSTANCE: invention relates to two-shaft gas turbine power plants of ground-based application and can be applied to drive of pumps, generators, and other mechanical equipment. Free power radial turbine comprises cylindrical rotor with discharge chamber. Along lengthwise axis of turbine, on cylindrical rotor working slots are arranged, total area thereof not less than area of nozzle hole of turbocompressor, and they made at angle of 45-60° to their radial lines. At side of coupling sleeve attached to turbocompressor, there is labyrinth seal. Cylindrical rotor is mounted on bearings in hub attached to casing with sealing flange, attached to coupling sleeve.
EFFECT: invention provides higher reliability and durability of free power turbine.
