Abstract (en)

[origin: CA2933628A1] Blade intended for a turbomachine impeller comprising N blades. At one end, the blade has a platform formed integrally with an airfoil of the blade. Over part of the axial extent of the blade, a section on a plane perpendicular to the axis (X) of the impeller of the flow path of the platform consists mainly of two straight-line segments arranged respectively on the two sides of the airfoil. These segments form, on each side of the airfoil, an angle of 90°-180°/N with respect to the radial direction. Figure 3.
