a base member including a first side, a second side opposite the first side, and a central opening passing through the first side and the second side, the second side including an outer circumferential edge defined by a first dimension of the base member and the central opening having an inner circumferential edge defined by a second dimension;
a plurality of blades extending outwardly from the first side, the plurality of blades extending about the central opening; and
a fuse element formed in the second side and extending along one of a radial direction and a circumferential direction, the fuse element forming a built-in failure mechanism including a uniform cross-section and having a length that is less than the first dimension, the fuse element causing a crack to propagate across the base member when the rotor is operated above a selected design speed, wherein the fuse element includes a first end positioned at the inner circumferential edge, a second end positioned at the outer circumferential edge, and an intermediate portion.
