  • Simultaneously disassembling rotor blades from a gas turbine engine rotor disk
    Patent number: 12000301
    Abstract: A method is provided for disassembling a rotor of a gas turbine engine. During this method, the rotor is provided which includes a rotor disk and a plurality of rotor blades arranged circumferentially about an axis. The rotor blades include a plurality of airfoils and a plurality of attachments that mount the rotor blades to the rotor disk. Each of the rotor blades includes a respective one of the airfoils and a respective one of the attachments. A press is arranged against the rotor. The press axially engages each of the rotor blades. The press moves axially along the axis to simultaneously push the rotor blades and remove the attachments from a plurality of slots in the rotor disk.

  • Simultaneously assembling rotor blades from a gas turbine engine rotor disk
    Patent number: 11808164
    Abstract: A method is provided for assembling a rotor of a gas turbine engine. During this method, a rotor disk is provided that includes an axis and a plurality of slots arranged circumferentially about the axis in an array. A plurality of rotor blades are provided that include a plurality of airfoils and a plurality of attachments. Each of the rotor blades includes a respective one of the airfoils and a respective one of the attachments. Each of the attachments is inserted partially into a respective one of the slots. The rotor blades are rested on top of a blade support structure. The blade support structure is lowered axially downward along the rotor disk to simultaneously seat the attachments into the slots.
