Abstract
A gas turbine engine rotor disk includes a web that extends inward in a radial direction from a rim to a bore that circumscribes an axis. An annular ridge extends axially from the side of the web. A balancing cut is in the annular ridge that includes a fillet that extends in the radial direction.
Claims3
A gas turbine engine rotor disk comprising:
- a web that extends inward in a radial direction from a rim to a bore that circumscribes an axis;
- an annular ridge extends axially from side of the web;
- and
- a balancing cut in the annular ridge that includes a fillet extending in the radial direction, wherein the balancing cut has spaced apart lateral fillets provided in a circumferential direction, and wherein the side has a generally planar surface, the fillet in the radial direction has spaced apart first and second axial heights relative to the generally planar surface at radial extremities of the balancing cut, the second axial height is arranged at a greater axial distance from the axis than the first axial height, the second axial height greater than the first axial height.
