Cross ship architecture for dispatch critical fuel tank inerting system

摘要

A fuel tank inerting system uses two “half systems” for providing inerting gas for the fuel tanks. Each inerting system may be composed of a temperature control and air pressurization unit (TCPU) and an air separation unit (ASU). A cross-ship duct and valve allows using one TCPU (sized for about half capacity or more, but less than full system capacity) connected to two ASUs. The inerting system may provide for redundancy in the TCPU section.
