Abstract: A pressure vessel includes a first wall defining a container and a second wall surrounding the container defining a cavity between the first wall and the second wall. The pressure vessel also includes a vent in the second wall providing fluid communication between the cavity and an outside of the second wall and matter positioned within the cavity configured to prevent flame from propagating through the cavity while providing thermal conductivity between the first wall and the second wall.

Abstract: A gas inerting system for an aircraft includes a fuel tank configured to contain a liquid fuel, a fuel vaporization system in fluid communication with the fuel tank and configured to receive the liquid fuel from the fuel tank, a source of air in fluid communication with the fuel vaporization system and configured to deliver air into the liquid fuel to produce the fuel vapor, a heat exchanger in fluid communication with the source of air at a location upstream of the fuel vaporization system, and a catalytic oxidation unit in fluid communication with the fuel vaporization system. The heat exchanger is configured to cool the air from the air source. A fluid connection is configured to deliver the fuel vapor to the catalytic oxidation unit.

Abstract: An air separation module includes a cylindrical canister and a separator. The cylindrical canister has a longitudinal axis, an inlet, an oxygen-depleted air outlet, and a drain portion with an oxygen-enriched air outlet. The separator is arranged within the cylindrical canister to separate a compressed air flow into an oxygen-depleted air flow fraction and an oxygen-enriched air flow fraction, the oxygen-depleted air flow fraction provided to the oxygen-depleted air outlet and the oxygen-enriched air flow fraction to the drain portion of the canister. The drain portion extends tangentially from the cylindrical canister to issue the oxygen-enriched air flow fraction with entrained condensate from the oxygen-enriched air outlet with a tangential flow component. Nitrogen generation systems and methods of removing condensate from air separation modules are also described.

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: Fuel tank inerting systems for aircraft are provided. The systems include a fuel tank, a catalytic reactor arranged to receive a first reactant from a first reactant source and a second reactant from a second reactant source to generate an inert gas that is supplied to the fuel tank to fill an ullage space of the fuel tank, a heat exchanger arranged between the catalytic reactor and the fuel tank and configured to at least one of cool and condense an output from the catalytic reactor to separate out the inert gas, and a controller configured to perform a light-off operation of the catalytic reactor by controlling at least one light-off parameter and, after light-off occurs, adjusting the at least one light-off parameter to an operating level, wherein the at least one light-off parameter comprises a space velocity through the catalytic reactor.

Abstract: Fuel tank inerting systems and methods for aircraft are described. The systems and methods include controlling of (i) a first reactant control element, (ii) a second reactant control valve, (iii) a ram air control valve, (iv) a driving mechanism, and (v) a flow control valve, to control a state of a fuel tank inerting system. The states of the fuel tank inerting system include an OFF state, a CIRCULATE state, a PRIME state, a CATWARM state, an ON state, a DEPRESSURIZE state, and a COOLDOWN state, wherein the states are determined in part by a prior state and/or a position/actuation of a given element of the system.
