ABSTRACT:
A bladed rotor includes a hub12with bayonet hooks34, 36, a bayonet ring64with bayonet projections66, 68that engage the hooks, and a load transfer element that occupies an annulus38defined by the hooks. Ideally, the load transfer element is a substantially circumferentially continuous snap ring60. If a blade separation event or other abnormality exerts an excessive axial load on a blade, the snap ring60safely distributes that load to the bayonet hooks34, 36to prevent the blade from severing the snap ring and being ejected axially from its slot.
