1. A fluid transport system for a gas turbine engine, comprising: a plenum configured to provide a fluid;an airfoil stator having an internal cavity and a radially outer boundary confining a core flow path for combustion gas; anda transfer tube radially outward of the radially outer boundary, the transfer tube arranged to transfer the fluid between the plenum and the internal cavity of the airfoil stator, the transfer tube including an inlet, an outlet having an airfoil shape and extending to the radially outer boundary, a second cavity of the transfer tube extending from the inlet to the outlet, and at least one partition wall dividing the second cavity of the transfer tube into multiple flow passages, the at least one partition wall dividing the inlet into equal inlet sub-areas and dividing the outlet into equal outlet sub-areas. 2. The system as recited in claim 1, wherein the second cavity of the transfer tube follows a curved path between the inlet and the outlet. 3. The system as recited in claim 1, wherein the inlet and the outlet define non-parallel planes. 4. The system as recited in claim 1, wherein the inlet has a first opening geometry and the outlet has a second opening geometry that is different than the first opening geometry. 5. The system as recited in claim 1, wherein each of the multiple flow passages opens at the inlet and at the outlet. 6. The system as recited in claim 1, wherein the at least one partition wall extends partially between the inlet and the outlet. 7. The system as recited in claim 1, wherein the at least one partition wall is solid and continuous. 8. The system as recited in claim 1, wherein the transfer tube is formed of joined powdered metal. 9. The system as recited in claim 1, further comprising a secondary plenum radially inwards of the plenum, and the transfer tube extends from the plenum through the secondary plenum to the internal cavity of the airfoil stator. 10. A gas turbine engine, comprising: a compressor section;a combustor in fluid communication with the compressor section;a turbine section in fluid communication with the combustor; anda fluid transport system configured to transport pressurized fluid from the compressor section, the fluid transport system including:a plenum connected to the compressor section to receive pressurized fluid from the compressor section,a secondary plenum radially inwards of the plenum;an airfoil stator having an internal cavity and a radially outer boundary confining a core flow path for combustion gas, and a transfer tube radially outward of the radially outer boundary, the transfer tube extends from the plenum through the secondary plenum to the internal cavity of the airfoil stator, the transfer tube arranged to transfer the pressurized fluid from the plenum into the airfoil stator, the transfer tube including an inlet, an outlet having an airfoil shape and that extends to the radially outer boundary, a second cavity of the transfer tube extending from the inlet to the outlet, and at least one partition wall dividing the second cavity of the transfer tube into multiple flow passages, the at least one partition wall dividing the inlet into equal inlet sub-areas and dividing the outlet into equal outlet sub-areas. 11. The gas turbine engine as recited in claim 10, wherein the inlet has a first opening geometry and the outlet has a second opening geometry that is different than the first opening geometry. 12. The gas turbine engine as recited in claim 10, wherein each of the multiple flow passages opens at the inlet and at the outlet. 13. The gas turbine engine as recited in claim 10, wherein the at least one partition wall is solid and continuous. 14. The gas turbine engine as recited in claim 10, wherein the secondary plenum is at a lower pressure than the plenum and the internal cavity of the airfoil stator. 15. The gas turbine engine as recited in claim 10, further comprising holes connecting the plenum and the secondary plenum such that the pressurized fluid can flow from the plenum to the secondary plenum. 16. The system as recited in claim 9, further comprising holes connecting the plenum and the secondary plenum such that the fluid can flow from the plenum to the secondary plenum. 17. The system as recited in claim 9, wherein the second cavity of the transfer tube follows a curved path between the inlet and the outlet, and the inlet and the outlet define non-parallel planes. 18. The gas turbine engine as recited in claim 15, wherein the second cavity of the transfer tube follows a curved path between the inlet and the outlet, and the inlet and the outlet define non-parallel planes.
