ABSTRACT:
Rotor blades40for a bladed rotor feature a chamfered attachment44that improves the energy absorption capability of a snap ring60used 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.
