Abstract
A device for rotationally blocking a retaining ring (20) on a rotor disk (10) includes successive first (162, 262) and second (164, 264) blocking hooks of the disk (10), at least one cleat (302, 304, 306) of the retaining ring (20) arranged close to a split (24) in the ring (20). The position of the at least one cleat (302, 304, 306) on the retaining ring (20) is such that, when the retaining ring (20) is in place in a groove (22) situated in the rotor disk (10), the at least one cleat (302, 304, 306) is in abutment against the first blocking hook (162, 262), and the split (24) is covered by the second blocking hook (164, 264).
