FIELD: machine building.
SUBSTANCE: turbine unit consists of the first device (200) of fixed blades, the second device (210) of fixed blades and a deflector (100) formed from a plate-type element. The deflector comprises the first section (101) of a hole with the first hole shape and the second section (102) of a hole with the second hole shape. The first hole section (101) comprises a configuration of inlet holes (104) forming the first hole shape. The second hole section (102) comprises an additional configuration of inlet holes (104) forming the second hole shape. The deflector (100) is spatially mounted on the first device (200) of fixed blades and on the second device (210) of fixed blades so that cooling fluid medium (106) can flow through the inlet holes (104) of the first hole section (101) to the first device (200) of fixed blades and the cooling fluid medium (106) can flow through the inlet holes (104) of the second hole section (102) to the second device (210) of fixed blades. The first shape of the hole differs from the second shape of the hole to reach the specified first flow of the cooling fluid medium (106) mass to the first device (200) of fixed blades and the specified second flow of the cooling fluid medium (106) mass to the second device (210) of fixed blades at the specified installation positions of the first device (200) of fixed blades and the second device (210) of fixed blades.
EFFECT: provision for proper cooling system of a turbine.
