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: An air separation module includes a separator, a canister, and a nominal-length end cap. The separator is arranged to separate ambient air into an oxygen-enriched air fraction and a nitrogen-enriched air fraction. The canister supports the separator and has a canister end flange, a canister intermediate flange and a canister end, the canister intermediate flange arranged between the canister end flange and the canister end. The nominal-length end cap is fixed to the canister end flange, and the separator extends between the canister end flange and the canister end. Nitrogen generation systems and methods of generating nitrogen-enriched air flows are also described.

Abstract: 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.
