FIELD: machine building.
SUBSTANCE: developed blade for bladed wheel of turbomachine, having N blades. At one end the blade has a flange which is formed as a whole with the blade body. On the blade length part in the axial direction, the wall section of the flange in the plane perpendicular to the wheel axis (X) is formed mainly by two first straight sections located on both sides of the blade, respectively. Each of said sections forms angle of 90–180°/N, relative to radial direction on both sides of the blade.
EFFECT: simplified manufacturing.
