TLDR
In this paper, a ring which is circumferentially expandable under centrifugal loading is proposed to constrain axial movement of individual blade members relative to the rotor axis.Abstract:
In an axial flow apparatus including stator and rotor elements, means are included for constraining axial movement of individual blade members relative to the rotor axis when the rotor is subjected to high centrifugal loading. The constraining means include a ring which is circumferentially expandable under centrifugal loading. Part of the outward radial force causing the expansion of the ring is directed axially against the blade members to provide an axially constraining force which is proportional to the centrifugal loading on the rotor. The invention herein described was made in the course of or under a contract or subcontract thereunder, (or grant) with the Department of the Army.read more

End seal for turbine blade bases
TL;DR: In this paper, an end seal for cooling air manifolds below the bases of a stage of air cooled turbine blades on a turbine wheel is proposed, where the planar portion is axially clamped to the wheel to define a 360° inboard seal while centrifugal forces developed by the end plates during rotation of the wheel cause the lugs to radially clamp the cylindrical flange against the cylinder shoulder on the wheel and blade bases.
