A vortex spoiler (180) for delivery of a cooling airflow (192) in a turbine (108) engine (100) including a plurality of inlet ports (182) formed circumferentially about a radial exterior sidewall (188), and a plurality of outlet ports (184) formed circumferentially about a radial interior sidewall (190). The plurality of inlet ports (182) are coupled to the plurality of outlet ports (184) via a plurality of ducts (186). Each of the ducts is formed having an interior diameter at the inlet port and the outlet port formed at a preselected angle normal to the surface of the each of the radial sidewalls to form a radially curved profile such that a cooling airflow (192) may pass radially inwardly through each of the plurality of ducts (186) with minimal tangential stress and minimal static pressure loss.
