Fuel tank inerting systems are provided. The systems include a fuel tank, an air source arranged to supply air into a reactive flow path, a catalytic reactor having a plurality of sub-reactors along the flow path, and a heat exchanger. The sub-reactors are arranged relative to the heat exchanger such that the flow path passes through at least a portion of the heat exchanger between two sub-reactors along the flow path. At least one fuel injector is arranged relative to at least one sub-reactor. The fuel injector is configured to inject fuel into the flow path at at least one of upstream of and in the respective at least one sub-reactor to generate a fuel-air mixture. A fuel tank ullage supply line fluidly connects the flow path to the fuel tank to supply an inert gas to a ullage of the fuel tank.

Catalytic fuel tank inerting system

A method for startup of a catalytic oxidation unit includes flowing air from an air source into the catalytic oxidation unit, recycling air from an outlet of the catalytic oxidation unit to an inlet of the catalytic oxidation unit through a recycle duct, and flowing a fuel from a fuel source into the catalytic oxidation to cause a catalytic reaction.

A method of coating a metal article is disclosed that includes immersing a metal article having an exterior anodized layer in a bath containing a chemically active corrosion inhibitor, and applying a voltage to the article during the immersing, the voltage driving the chemically active corrosion inhibitor from the bath into the exterior anodized layer. An article is also disclosed that has a substrate comprising a metal, and a porous anodized layer formed on an exterior surface of the substrate that is infiltrated with a chemically active corrosion inhibitor, the anodized layer having an inward-facing region and an outward-facing region, the anodized layer having a greater concentration of chemically active corrosion inhibitors in the inward-facing region than in the outward-facing region.

A system and method satisfies temperature and pressure requirements of solid oxide fuel cell systemin a manner that increases the overall efficiency and decreases the overall weight of system. The system and method include a secondary blowerfor boosting air stream pressure level sufficient for operation of a reformerthat is designed to minimize pressure drop; an integrated heat exchangerfor recovering heat from exhaustand comprising multiple flow fieldsA,B,C for ensuring inlet temperature requirements of a solid oxide fuel cellare met; and a thermal enclosurefor separating hot zonecomponents from cool zonecomponents for increasing thermal efficiency of the system and better thermal management.
