A balance weight for the rotor of a gas turbine engine is adapted to mount within the cavity formed between the innermost surface of the dovetail slots formed in the circumference of the rotor disk and the bottom of the dovetail root of the rotor blades inserted within the dovetail slots. The balance weight has a head portion formed with a bottom surface which mates with the innermost surface of the dovetail slots, and a lip connected to the head portion which engages the aft surface of the rotor disk. The balance weight is supported in an aft direction within the dovetail slots by an aft blade retainer having a shoulder or projection which contacts the balance weight.

A balanced rotor of a gas turbine engine, comprising: a rotor disk formed with circumferentially spaced slots each having a radially innermost surface; a row of turbine rotor blades extending radially outwardly from the circumference of said rotor disk, each of said rotor blades being formed with a blade root having a bottom surface, said rotor blades being insertable within said dovetail slots of said rotor disk so that a cavity is formed between said bottom surface of said blade root and said radially innermost surface of said slots; balance means insertable within said cavity for balancing said rotor; and wherein said rotor disk has an aft surface and a forward surface, said balance means comprising a balance weight having a bottom surface engageable with said radially innermost surface of said slots in said turbine disk and a lip engageable with said aft surface of said rotor disk.
