1. A balanced rotor for a turbine engine, comprising:
a rotor component extending around an axis and having a circumferential slot; a row of rotor blades extending radially outwardly from the circumference of the rotor component, each blade having a blade root inserted within the circumferential slot; and a balance weight within the circumferential slot, the weight having a land which extends beneath a blade root and having a mass-adjustment protrusion extending from the land in a radial direction relative to the axis of the rotor component and which lies wholly between the blade root and an adjacent blade root and has a width in the axial direction that is less than the axial width of the slot, wherein the slot has a radially outer neck opening to a radially inner securing cavern, and the width of the mass adjustment protrusion is less than the width of the slot neck; wherein the land has edges that extend in a circumferential direction, the edges each having a lip aligned with a respective root chamfer for prohibiting axial movement of the weight relative to the root; and wherein each lip extends from the land in the same direction in which the mass-adjusting protrusion extends. |
