Abstract
A seal assembly that may be for turbine engine includes a first wall defining in-part a first flowpath and a second wall defining in-part a second flowpath having a pressure that is greater than the first flowpath. The second wall has a plurality of metering apertures in fluid communication between the second flowpath and a cavity defined by and between the first and second walls. The walls may be convoluted and generally, resiliently compressed between two substantially opposing surfaces for providing a seal between the two flowpaths.
