  • Aircraft fuel system
    Patent number: 8777165
    Abstract: An aircraft fuel system has a fuel tank with first and second cells separated by one or more baffles. A venting system reduces pressure difference between the interior and exterior of the fuel tank, and an inerting system supplies oxygen-depleted gas to the fuel tank. The baffles permit the flow of fluid between the cells. The venting system has one or more vent nozzles within the fuel tank and in fluid communication with one or more vent ports. The inerting system has one or more inerting nozzles for injecting oxygen-depleted gas into the first and second cells. A control device varies the ratio between the total flow rates of the oxygen-depleted gas into the first and second cells.
