  • Axial retention system and components thereof for a bladed rotor
    Patent number: 6951448
    Abstract: A bladed rotor includes a hub 12 with bayonet hooks 34, 36, a bayonet ring 64 with bayonet projections 66, 68 that engage the hooks, and a load transfer element that occupies an annulus 38 defined by the hooks. Ideally, the load transfer element is a substantially circumferentially continuous snap ring 60. If a blade separation event or other abnormality exerts an excessive axial load on a blade, the snap ring 60 safely distributes that load to the bayonet hooks 34, 36 to prevent the blade from severing the snap ring and being ejected axially from its slot.
