FIELD: machine building.
SUBSTANCE: cooled blade of turbomachine of cooling loop diagram includes a perforated cover with radial partition walls forming radial channels, and projections-generators of near-wall turbulence on its inner surface, which are located with inclination to transverse direction of the channel axis, as well as with heat removal intensifiers in cooling channels of radial partition wall of trailing edge of the blade. Projections-generators of the near-wall turbulence are provided with a radial slot on contact with the partition wall on the side of rotating inlet air. Radial partition wall of the trailing edge of the blade has a radial division channel.
EFFECT: invention improves the blade cooling efficiency.
