A multi-ply finger seal with a first ply that is subject to a first amount of deflection during operation of the gas turbine engine and a second ply that is subject to a second amount of deflection during operation of the gas turbine engine. The first amount of deflection of the first ply differs from the second amount of deflection of the second ply. The differing amounts of deflection can result from the first ply and second ply being constructed from materials that have different coefficients of thermal expansion. Additionally or alternatively, the first ply can have a stiffness that differs from the stiffness of the second ply. |
