초록

Rotor blades 40 for a bladed rotor feature a chamfered attachment 44 that improves the energy absorption capability of a snap ring 60 used as one component of a blade axial retention system. The chamfered attachment plastically deforms the snap ring rather than shearing through it in response to abnormally high forces exerted on the blade.
