Abstract:
A blade for a turbomachine bladed wheel having N blades.At one end, the blade presents a platform that is formed integrally with an airfoil of the blade.Over a portion of the axial extent of the blade, a section through the platform wall on a plane perpendicular to the axis (X) of the wheel is constituted mainly by two first straight line segments arranged respectively on the two sides of the airfoil.Each of these segments forms an angle of 90°-180°/N relative to the radial direction on either side of the airfoil.
