Abstract
Rotor bladesfor a bladed rotor feature a chamfered attachmentthat improves the energy absorption capability of a snap ringused 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.
