Definitions
- the assembly according to the invention may be subject to the following improvements: - A plane in which a gap between the skeletal curve and the linearized skeleton curve is maximum may be substantially coincident with the plane of said hollowest section.
- the hollowest section may be located axially between 15 and 40% of the axial extent of the blade, from its leading edge.
- Each blade 20 comprises a leading edge 26 and a trailing edge 28, and extends radially in a radial direction B specific to each blade.
- the arrangements of the platform surface 30 and the blades 20 are furthermore defined axially with respect to the axial extent E of the blades 20.
- the plane of the section d3 is preferably situated axially on either side of the hollowest section 41, namely between the position 0.5 x N% of the hollowest section 41, and 1 , 5 x N%, the value N being a percentage expressed with respect to the axial extent E of the blade 20.
- the plane P (of the hollowest section 41 of the Circumferential depression 40) is approximately 30% of E.
- the most hollow section must therefore be between 0.5 x 30% and 1.5 x 30%, that is to say between 15% and 45% of E. This is the case for the first embodiment, since section d3 is 30% of E for curve 46, and for the second embodiment, since section d3 of Curve 47 is 40% of E.
