Abstract: The present invention relates to a thermally compliant liner (50) for a gas turbine engine. The liner includes an outer wall (100), an inner wall (110) spaced radially inwardly from the outer wall leaving a duct (112) therebetween. A plurality of stiffeners (120) are disposed in the duct (114). The stiffeners (120) include a flexible medial portion (128) which accommodates differential rates of thermal growth between the outer and inner walls (100,110). The stiffeners (120) also include radially extending portions (124) which in conjunction with the medial portion (128), minimize buckling of the liner due to pressure differentials.
