A bladed rotor arrangement (32) comprising a rotor (34), a plurality of rotor blades (36), at least one seal plate (68) and a plurality of lock plates (48). Each rotor blade (36) locates in a corresponding axially extending slot (46) in the rotor (34). A plurality of lock plates (48) are arranged at a first axial end of the rotor (34), the radially outer ends (48A) of the lock plates (48) engage grooves (52) on the platforms (40) of the rotor blades (36), and the radially inner ends (48B) of the lock plates (48) engage a circumferentially extending groove (60). The seal plate (68) is arranged at the first axial end of the rotor (34), the radially inner ends (48B) of the lock plates (48) engage a circumferentially extending groove (60) defined by the seal plate (68). The seal plate (68) has at least one projection (68B) extending axially from the seal plate (68) and arranged to locate in a slot (45) in a first axial end of the root (44) of a rotor blade (36). |
