ABSTRACT:
A blade retention system for retaining blade roots in slots of a rotor hub disk, the rotor blade having a radially outward blade tip requiring surface material removal by grinding to acquire a finished ground surface, having a blade root retention tab with an elongated web of thickness less than the gap between the slot and blade root and with at least two deformable protrusions extending radially to a height exceeding said gap, the protrusions adapted to deform under compression radially inwardly on sliding engagement with the blade root in the slot and to exert a reaction force radially outwardly on the blade root of a magnitude sufficient to secure the blade tip during surface removal grinding of the blade tip against radial displacement and against rotational displacement.
