FIELD: machine building.
SUBSTANCE: cooling method of blades of at least one of blade rim in rotary machine comprises channel axial flow, which is radially restricted from inside rotor assembly and outside by at least one fixed component. Blades are arranged on rotary assembly and provide blade shrouded top radially directed to fixed component. Cooling air is forced radially outside to top of each blade in at least one vaned rim. Cooling air under pressure penetrates into blade through at least one hole in shrouded tops of blade. Cooling air is forced through fixed component surrounding said at least one blade ring radially, and it enters into cavity enveloped with fixed component and as shrouded tops of blades in at least one vaned rim.
EFFECT: invention is aimed at simplification of air supply into rotary blade of rotor machine.
