FIELD: machine building.
SUBSTANCE: gas turbine component to create part of gas turbine stage, made with possibility of change of the cooling diagram, includes shaped section of blade, cooling passage, film holes and replaceable connectors. The shaped section of the blade contains trough and back, connected on chord opposite input edge and output edge. The cooling passage continues between the trough and back along the input edge to ensure the cooling fluid flowing through it. The film holes are made in the cooling passage to ensure flowing of at least part of cooling fluid to part of shaped section of the blade. Replaceable connectors are made with possibility of change for the cooling passage of the cooling diagram one-by-one.
EFFECT: increased cooling efficiency due to change of the cooling diagram.
