FIELD: turbine engineering. SUBSTANCE: turbine cooled blade is hollow feather 1 with longitudinal partition 2, perforation holes 3 in vicinity of entrance edge, and deflector 4 with holes 5; made in longitudinal partition are holes 6; arranged against them are conical stampings facing deflector 4 that has corrugated walls with their corrugation tops abutting against inner surface of contracting part of blade feather 1; jets 8 are installed in blade root attachment to pass air both to front and rear spaces of blade, the latter space being formed by longitudinal partition 2 and front end of deflector 4. EFFECT: improved design. 2 dwg
