Abstract: The present invention provides a method of replacing a failed pump seal of a pump having a pump housing and a rotating pump shaft. As part of the method, there is provided a specially configured rescue seal. The rescue seal is placed on the pump shaft above the failed seal so that the pump shaft extends through both the failed seal and the rescue seal. In order to affix the rescue seal to the pump shaft and above the failed seal, a plurality of studs are first attached to the pump housing after removing some of the bolts that fasten the failed seal to the pump housing. The failed seal is then secured to the studs with nuts. Nuts are then placed on the studs to secure the rescue seal to the studs above the failed seal.

Abstract: A part of a gasket that conducts electricity across the otherwise nonconducting gasket.

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.

Accordingly, production costs may be decreased by simplifying the structure of the gasket as described above.
