Abstract
A seal ring for use between an integrally bladed rotor and a hub rotor of a compressor section of a gas turbine engine includes an arm configured to be positioned between the integrally bladed rotor and the hub rotor, such that the seal ring is removably coupled to the integrally bladed rotor and the hub rotor in response to a compressive force applied to the arm by the integrally bladed rotor and the hub rotor. The seal ring also includes a first blade coupled to the arm and configured to form a seal between a first volume and a second volume.
