Gas turbine engine spring mounted manifold

A thermal control assembly comprising:

• a spring mounted thermal air distribution manifold encircling a portion of an outer casing, wherein the manifold comprises an annular row or hoop of arcuate panels, and wherein each of the arcuate panels comprises an arcuate panel base and at least one panel header extending axially from and sealingly attached to a radially outwardly facing surface of the arcuate panel base;
• a number of plenums, wherein at least one plenum is located between the panel header and the arcuate panel base;
• one or more spray tubes or channels depending radially inwardly from and mounted on or attached to a radially inwardly facing surface of the arcuate panel base, wherein the spray tubes or channels are in fluid communication with the plenums;
• radially outwardly biasing springs mounted on or attached to the radially inwardly facing surface of the arcuate panel base and contacting the outer casing;
• and
• connecting hinges pivotably attaching adjacent ones of the arcuate panels in the hoop, wherein each of the connecting hinges comprises clockwise and counter-clockwise hinge wings pivotably connected together, and wherein the clockwise and counter-clockwise hinge wings are attached to clockwise and counter-clockwise ends respectively of adjacent ones of the arcuate panel bases.
