A method for balancing a compressor rotor assembly including a forward weldment () and an aft weldment () includes pre-balancing the aft weldment () of the compressor rotor assembly () with compressor disks () prior to populating the compressor disks () with circumferentially installed compressor rotor blades (). Pre-balancing the aft weldment () includes measuring a rotational balance of the aft weldment (). Pre-balancing the aft weldment () also includes determining a number of underplatform weights () needed and a location for each underplatform weight () within a circumferential slot () of one the compressor disks (). Pre-balancing the aft weldment () further includes mounting each underplatform weight () in the determined location.

Gas turbine engine compressor rotor assembly and balancing system

A first stage compressor disk of a gas turbine engine includes a body. The body includes a forward end, an aft end, and an outer surface. The body also includes a plurality of forward balancing holes through the outer surface. The forward balancing holes align circumferentially about the body. The body further includes a plurality of aft balancing holes through the outer surface. The aft balancing holes align circumferentially about the body and are located aft of the forward balancing holes. The first stage compressor disk also includes a radial flange at the aft end of the body. The radial flange extends radially outward from the body. The radial flange includes slots for mounting airfoils.
