A bladed rotor arrangement comprising a rotor, a plurality of rotor blades, at least one seal plate and a plurality of lock plates. Each rotor blade locates in a corresponding axially extending slot in the rotor. A plurality of lock plates are arranged at a first axial end of the rotor, the radially outer ends of the lock plates engage grooves on the platforms of the rotor blades, and the radially inner ends of the lock plates engage a circumferentially extending groove. The seal plate is arranged at the first axial end of the rotor, the radially inner ends of the lock plates engage the circumferentially extending groove defined by the seal plate. The seal plate has at least one projection extending axially from the seal plate and arranged to locate in a slot in a first axial end of the root of a rotor blade. |

1. A bladed rotor arrangement comprising a rotor, a plurality of rotor blades, at least one seal plate and a plurality of lock plates,
the rotor blades being mounted on the periphery of the rotor, each rotor blade comprising an aerofoil, a platform, a shank and a root, each platform having at least one radially inwardly extending flange, the rotor comprising a plurality of circumferentially spaced axially extending slots, the rotor having a first axial end and a second axial end, the root of each rotor blade locating in a respective one of the axially extending slots in the periphery of the rotor, a plurality of lock plates being arranged at the first axial end of the rotor, each lock plate having a radially inner end and a radially outer end, the radially outer ends of the lock plates at the first axial end of the rotor engaging grooves defined by the radially inwardly extending flanges on the platforms of the rotor blades, at least one seal plate being arranged at the first axial end of the rotor, the radially inner ends of the lock plates at the first axial end of the rotor engaging a circumferentially extending groove at least partially defined by the at least one seal plate at the first axial end of the rotor, the at least one seal plate at the first axial end of the rotor having at least one anti-rotation feature, the at least one anti-rotation feature comprising a projection extending axially from the at least one seal plate and arranged to locate in a slot in a first axial end of the root of a rotor blade. |
