TWO PIECE RETRACTABLE ENGINE CENTER BODY FOR BALANCING

Abstract: a gas turbine engine includes a propulsor having a rotor with blades, and an adapter connecting the rotor to a drive line at a connection. the drive line is connected to an accessory. the drive line and the accessory are received within a static center body. bolts secure the adapter to the rotor. the center body has a rear end closely spaced from the connection, such that the center body limits access to the connection of the adapter to the rotor. the center body is formed with a forward portion and a separate rear portion defining the rear end. the forward portion and the rear portion are secured together. the rear portion is selectively slidable relative to the forward portion such that the rear portion can be moved away from the connection to provide access to change balance members. a method is also disclosed.
