FIELD: machine engineering.
SUBSTANCE: turbomachine unit includes a blade for guiding the hot gas during the turbomachine operation, the stator ring for blade mounting, a heat shield to protect the stator ring from the hot gas flow. The heat shield is located in the direction of hot gas flow movement in front of the stator ring. The heat shield comprises a plurality of channels formed in it for cooling air guiding. The channels are arranged so that the cooling air is discharged into the hot gas flow path.
EFFECT: stator ring protection from the hot air flow and efficient blade cooling.
