Method for producing a plurality of turbine engine blades

A method (100) for producing a plurality of turbine engine blades (10) having a height (Ha), the method comprising:

• providing a mold (30) comprising an internal cavity, the internal cavity being bounded by an internal side face (34) of the mold which is axisymmetric about a longitudinal axis (X), the side face (34) extending along the longitudinal axis (X) to a height (Hf) which is greater than or equal to the height (Ha) of each blade (10), the side face (34) defining a plurality of sections (34i) which are perpendicular to the longitudinal axis (X), each section (34i) of the side face (34) having a radius (Rfs), the side face (34) of the mold (30) being such that, for each section (34i), the ratio of the height (Hf) of the side face (34) to the radius (Rfs) of the section (34i) is less than or equal to equal to 2.0;
• positioning the mold (30) so that the longitudinal axis (X) is aligned with the gravity field (g),
• rotating the mold (30) about the longitudinal axis (X) at a rotation speed (ω) comprised between 200 rpm and 800 rpm,
• pouring a material into the internal cavity of the mold (30) so as to form, by centrifugation, a tubular part (20) extending along the longitudinal axis (X).
