FIELD: power-plant engineering. SUBSTANCE: turbine wheel has disk with running blades having T-shaped roots and shoulders contacting annular ridges of disk ring, locking-piece blades provided with part 16 and root 17 joined with disk by means of rivets 18. Shoulders 14 are made in part 16 of locking-piece blades and bosses are made at points of installation of locking-piece blade on disk. Diameters of rivets 18 are reduced as they are spaced from axis of revolution of turbine wheel; these diameters are selected from definite equation. EFFECT: improved design. 6 dwg
