Abstract
A highly adaptive seal for use in advanced aircraft propulsion and missile systems is provided. The seal is capable of effectively limiting invasive thermal energy and corrosive airflow from entering the internal systems and hardware of the aircraft by managing and controlling the incoming air flow. The seal is configured to be disposed between component parts of the aircraft and create a tortuous path for air flow. The seal maintains contact with the component parts between which it seals by allowing for significant radial and axial displacement freedom of the component parts. Accordingly, hot gas intrusion may be limited in a wide variety of dynamic environments and component displacement conditions. Limiting such hot gas intrusion has a substantial impact on component survivability over the course of free flight of an aircraft.
