FIELD: machine building.
SUBSTANCE: guide blade or rotating blade includes aerodynamic surface (1) with shaped sections (3, 5, 15A-15E) having span, bending line and front edge (7), on which bending line encloses with axial direction of the compressor an angle of blade front edge. On rear edge the bending line encloses with axial direction (A) of compressor an angle of rear edge. Shaped sections (3, 5, 15A-15E) of blade aerodynamic surface are located one above another on front edge (7) along straight line passing in radial direction (R) of compressor from compressor hub to compressor housing. Angles of front edge of shaped sections of aerodynamic surface vary along the span and more for shaped sections of aerodynamic surface near the hub and near the wall than for shaped sections of aerodynamic surface in the middle of the span.
EFFECT: reduction of spatial losses and increase in stability margin at adequate strength margin.
