Abstract: A rotor assembly. The rotor assembly may include a rotor, at least one axial slot positioned about the rim of the rotor having a first staking recess positioned therein, a blade positioned within each of the axial slots having a second staking recess positioned therein, a staking insert having a base portion and a projection extending therefrom with the base portion being disposed within the first staking recess and the projection being disposed within the second staking recess, and a shim positioned within the first staking recess adjacent to the base portion, opposite the projection, of the staking insert. The first staking recess retains the staking insert while the projection of the staking insert retains the blade in both the aft and forward directions.

Abstract: Systems are disclosed herein for enhancing the longevity of turbomachine components. Such systems include a turbomachine blade that has a blade portion extending from a base portion. The base portion includes an axial rail configured to extend into an axial groove disposed in a rotor of a turbomachine. The axial rail includes a first locking recess configured to align with a second locking recess along the axial groove. The system also includes a blade locking assembly having a first locking insert and a second locking insert. The first locking insert is configured to be inserted in both the first and second locking recesses. The second locking insert is configured to be inserted in the first or second locking recess adjacent the first locking insert.
