A cooling system for a turbomachine includes a vane (201) having an outer diameter platform (203) at one end and an inner diameter platform (209) at another end opposite the outer diameter platform. The outer diameter platform includes outer diameter attachment structure operative to mount the vane to an outer diameter stationary structure. The inner diameter platform is operative to be disposed on an inner diameter stationary structure. The cooling system also includes an airfoil (215) disposed between the outer diameter platform and the inner diameter platform and defining a first cross-passage (241). The first cross-passage defines a first outer diameter opening (243) in the outer diameter platform. The first cross-passage defines a first inner diameter opening (245) in the inner diameter platform such that a first leakage flow (247) can pass through the vane from the inner diameter platform, through the airfoil, to the outer diameter platform, and into an outer diameter leakage path (225b, 249) of the vane. |
