1. An airfoil defining a camber axis, a transverse direction orthogonal to the camber axis, and a radial direction orthogonal to the transverse direction, the airfoil comprising:
a leading edge;
a trailing edge;
a pressure side wall and a suction side wall each extending between the leading edge and the trailing edge, wherein a camber axis is defined halfway between the pressure side wall and the suction side wall; and
a cooling circuit defined in the airfoil, the cooling circuit having a trailing edge cooling circuit comprising a pressure side channel and a suction side channel, the pressure side channel disposed in cooling proximity to the pressure side wall and the suction side channel disposed in cooling proximity to the suction side wall;
wherein the pressure side channel converges in cross-sectional area from a pressure side inlet to a pressure side outlet adjacent the trailing edge;
wherein the suction side channel converges in cross-sectional area from a suction side inlet to a suction side outlet adjacent the trailing edge; and
wherein the pressure side inlet overlaps with the suction side inlet in both the radial direction and the transverse direction.
