Abstract
A pass through passage assembly of a gas turbine engine includes a compartment wall located between a first compartment and a second compartment, and a wall opening in the compartment wall connecting the first compartment and the second compartment, the wall opening having a central axis. A passage insert extends from the first compartment to the second compartment. A seal plate is positioned at the second compartment and extends about the central axis such that the compartment wall is located between an insert flange and the seal plate. A backing plate is positioned and retained between seal plate and the compartment wall, with the seal plate, the backing plate, the compartment wall, and the passage insert defining a seal cavity therebetween. A rope seal is located in the seal cavity and is retained in the seal cavity by the backing plate, the seal plate and the passage insert.
