  • Bladed rotor arrangement and a lock plate for a bladed rotor arrangement
    Patent number: 10041362
    Abstract: A lock plate of a bladed rotor arrangement is hollow. The bladed rotor arrangement comprises is a bladed turbine rotor of a gas turbine engine. The hollow lock plate has reduced weight compared to a solid lock plate and reduces the centrifugal load on the rim of the rotor and reduces the stresses in the lock plate groove on the rotor blade and hence increases the working life of the rotor and the working life of the rotor blade respectively. The lock plate may have radially extending chambers and openings to provide a flow of coolant onto the rotor posts of the rotor.
