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.

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

Abstract: An air separation module includes a canister extending between a first end and an opposite second end, a separator fixed within the canister to separate a compressed air flow into an oxygen-enriched air flow fraction and an oxygen-depleted air flow fraction, and a one-piece cap. The one-piece cap is connected to the first end of the canister and has a filter module mount portion on a side of the one-piece cap opposite the separator to support a filter module with the air separation module. Nitrogen generation systems and methods of making air separation modules are also described.
