Abstract
A first rotor piece includes a first ring provided with a succession of holes and notches. An assembly is formed by a second rotor piece fixed to a third rotor piece. The second piece ends downstream in a second ring including holes. The third piece ends upstream in a third ring including holes. The second and third rings are arranged against each other with their holes in alignment, and are fixed together by first fasteners. The first ring is arranged upstream of and against the assembly so that the notches fit around the first fasteners so that some of the holes of the first ring are aligned with holes of the assembly, with second fasteners fixing the first ring to the assembly.
