MULTISTAGE GAS POWER TURBINE WITH CANTILEVER MOUNTING Russian patent published in 2018 - IPC F01D1/06 

FIELD: turbines.

SUBSTANCE: invention relates to a two-shaft gas turbine power plant for surface use, which use as a motor a turbocharger from an internal combustion engine with an external combustion chamber. Multi-stage gas power turbine with a cantilever mounting, Rotor containing a disk with working blades at the outlet of the turbine is provided with a gas cavity. On the disk, located on the shaft of the rotor. At least two stages of working blades with a labyrinth seal are located. Before the first stage and between the stages of the working blades, the blades of the guide apparatus are located and fixed to the turbocompressor parallel to the longitudinal axis of the rotor. Rotor under the action of the reactive forces of the gas flow, moving from the gas cavity through the vanes of the directing device and working blades of the first stage, further through the vanes of the guide apparatus and the working blades of the second stage, produces a rotation.

EFFECT: increase in the mechanical efficiency of the rotor of a free power radial turbine and reliability is achieved.
