1. A compressor, comprising:
an outer circumferential support structure and an inner circumferential support structure, the outer and inner circumferential support structures positioned concentrically around a central axis; and
an aft-most stage comprising a vane extending radially inward from the outer circumferential support structure, an axial length of the aft-most stage being defined by a spacer arm of the inner circumferential support structure,
wherein the vane comprises a root, a tip, and a trailing edge extending between the root and the tip, the root positioned at the outer circumferential support structure,
wherein a ratio of (1) a first radial distance (Ch) between a first point located at an intersection of the tip of the vane and the trailing edge to a radially inner wall of the spacer arm of the inner circumferential support structure to (2) a second radial distance (Vh) between the first point and a second point located at an intersection of the root of the vane and the trailing edge is between 0.95 and 5.1, and
wherein Ch is between 0.525 inches and 4.663 inches and Vh is between 0.553 inches and 0.918 inches.
