A balanced rotor component, for a gas turbine engine, is rotatable about an axis, in use. The component has at least one slot having a profile holding a complementary profile of a root portion of a blade member. The slot holds a balance weight 40 which is in contact with the base of the slot at rest, and wherein the balance weight is located within a cavity in the root portion. The slot may be axial, with the cavity having an axially forward and/or axially rearward wall defining the cavity. The walls may diverge and converge with respect to a centre line defined there between. The lateral sides of the cavity may be open. The radially inner surface of the balance weight may have a form which matches the base of the slot. The balance weight may have a radially extending protrusion engaging a hole in the root. |
