摘要： A gas turbine engine thermal control double-wall apparatus 312 for active clearance control and a method of using the apparatus are provided herein. The apparatus 312 has a thermal air distribution manifold 350 encircling an axially extending portion of an engine outer casing 466. The manifold 350 has a plurality of header assemblies 357 with an annular supply tube 354 and a plurality of annular spray rails 460 in fluid supply communication with at least one of the plurality of supply plenums 356. The annular spray rails 460 define spray holes 462 that are oriented to impinge thermal control air 336 onto the outer casing 466 having at least one thermal control ring 484 attached thereto before being exhausted from circumferentially extending exhaust passages 526. All of the thermal control apparatus 312 surfaces in direct contact with the thermal control air 336 are constructed of an integrated double wall heat shield 610 defining a hermetically sealed cavity 612 between the walls therein.
