FIELD: machine building.
SUBSTANCE: turbine output device contains profiled supports of the casing located in flow-through part downstream turbine wheel of last stage. The middle lines of profile output areas of supports are directed along the turbine longitudinal axis. The middle lines of profile input areas of supports are turned to turbine longitudinal axis by 20-40° towards rotation of turbine wheel of last stage.
EFFECT: invention provides the possibility of obtaining maximum efficiency of turbine last stage at practically axial gas flow at the outlet of turbine output device.
