Abstract
A bladed rotor includes a hubwith bayonet hooks, a bayonet ringwith bayonet projectionsthat engage the hooks, and a load transfer element that occupies an annulusdefined by the hooks. Ideally, the load transfer element is a substantially circumferentially continuous snap ring. If a blade separation event or other abnormality exerts an excessive axial load on a blade, the snap ringsafely distributes that load to the bayonet hooksto prevent the blade from severing the snap ring and being ejected axially from its slot.
