FIELD: engines and pumps.
SUBSTANCE: blade of turbomachine rotor contains flange on its outer end and sealing ledges located upstream and downstream. Blade flange forms outer surface of channel for gas passing through passage, and has first and second opposite lateral edges. Sealing ledges extending outward from flange between two side surfaces arranged at first and second side edges. Side surfaces of upstream and downstream ledges are coated with at least partially, wear-resistant material. Invention also relates to turbomachine comprising above blade.
EFFECT: group of inventions reduces weight and dimensions of rotor blade of turbomachine due to use of side surfaces of sealing ledges as surfaces of contact between adjacent flanges of blades.
