FIELD: mechanical engineering; turbomachines.
SUBSTANCE: proposed cooled perforated blade of turbomachine contains perforated envelope with ribbing on inner surface and with heat barrier coating on outer surface. Ribbing on inner surface of blade envelope is made so that holes pierce the ribbing, envelope and heat barrier coating, and heat barrier coating is provided with slots behind the holes in direction of gas-flow.
EFFECT: improved efficiency of blade cooling.
