PROBLEM TO BE SOLVED: To provide an improved axial retention system for a bladed rotor such as a turbine engine fan rotor. SOLUTION: The axial retention system for the 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 34, 36. 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 40, the snap ring 60 safely distributes that load to the bayonet hooks 34, 36 to prevent the blade 40 from severing the snap ring 60 and being ejected axially from its slot 16.
