摘要： A turbine frame cooling system (100) for use with a gas turbine engine (10) includes an outer ring (102) defining a cavity (118) and a hub (104) positioned radially inward of the outer ring. The turbine frame cooling system also includes a plurality of circumferentially-spaced first fairings (106) coupled between the outer ring and the hub and a plurality of circumferentially-spaced second fairings (108) coupled between the outer ring and the hub, wherein the first and second fairings are alternatingly positioned about the hub. The turbine frame cooling system also includes a plurality of circumferentially-spaced air scoops (116) coupled to the outer ring. The plurality of air scoops extend into a bypass stream (40) and are configured to channel a bypass air cooling flow (52) into the cavity of the outer ring.
