Abstract: A system is disclosed for inerting a fuel tank. The system includes a fuel tank and an air separator including an air inlet, a membrane with a permeability differential between oxygen and nitrogen, an oxygen-depleted air outlet, and an oxygen-enriched air outlet. A catalytic reactor is arranged to receive oxygen-depleted air from the oxygen-depleted air outlet and fuel, to react the fuel with oxygen in the oxygen-depleted air, and to discharge an inert gas from a reactor outlet. An inert gas flow path is arranged to receive inert gas from the reactor outlet, or from the air separation module oxygen-depleted air outlet, or from the reactor outlet and from the air separation module oxygen-depleted air outlet, and to direct inert gas to the fuel tank.

Abstract: A fuel tank inerting system is disclosed. In addition to a fuel tank, the system includes a catalytic reactor with an inlet, an outlet, a reactive flow path between the inlet and the outlet, and a catalyst on the reactive flow path. The catalytic reactor is arranged to receive fuel from the fuel tank and air from an air source, and to react the fuel and air along the reactive flow path to generate an inert gas. The system also includes an inert gas flow path from the catalytic reactor to the fuel tank. The system also includes a non-uniform catalyst composition along the reactive flow path.

Abstract: A fuel tank inerting system includes a primary catalytic reactor comprising an inlet, an outlet, a reactive flow path between the inlet and the outlet, and a catalyst on the reactive flow path. The catalytic reactor is arranged to receive fuel from the fuel tank and air from an air source that are mixed to form a combined flow, and to react the combined flow along the reactive flow path to generate an inert gas. The system also includes an input sensor that measures a property of the combined flow before it enters the primary catalytic reactor and an output sensor that measures the property of the combined flow after it exits the primary catalytic reactor.
