PROBLEM TO BE SOLVED: To increase performance of turbomachinery by decreasing the draw of air supply.SOLUTION: Embodiments of the present disclosure include a cooling supply circuit within a turbine wheel. The cooling supply circuit may include: a substantially axial passage configured to communicate air along an axial length of the turbine wheel; a substantially radial inlet positioned within the turbine wheel between a hollow interior of the turbine wheel and the substantially axial passage, the inlet being configured to direct a rotor purge air into the substantially axial passage; and a substantially radial outlet positioned within the turbine wheel between the substantially axial passage and a cooled component coupled to a radial exterior of the turbine wheel, the outlet being configured to direct the rotor purge air towards the cooled component, the outlet being axially displaced from the inlet. |
