Systems and methods for attaching one or more impellers to a shaft and attaching composite rings to a back and front lip on each impeller to secure the impellers for high angular velocity operation. The composite rings are constructed of a material that provides a greater specific strength and greater specific stiffness relative to the material of the impellers. In multi-impeller assemblies, an impeller spacer is attached between each pair of impellers. |
