    Abstract: An environmental control system that includes a first environmental control system pack, a first recirculation fan assembly, and a cabin air sensor unit. The first environmental control system pack is arranged to provide conditioned air to an aircraft cabin. The first recirculation fan assembly is arranged to recirculate a first cabin air fluid flow back to the aircraft cabin. The cabin air sensor unit is arranged to provide a first air quality signal indicative of an air quality of the first cabin air fluid flow to a controller.

    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) an air distributor in the catalytic reactor arranged to distribute air along the reactive flow path, or (b) non-uniform catalyst loading or non-uniform catalyst composition along the reactive flow path, or both (a) and (b).

    Abstract: A fuel tank inerting system is disclosed. The system includes a fuel tank and a catalytic reactor. The catalytic reactor is arranged to receive a first reactant from a first reactant source and to receive a second reactant from a second reactant source, and to react the first and second reactants to generate an inert gas. The system also includes an inert gas flow path from the catalytic reactor to the fuel tank. The catalytic reactor includes first, second, and third flow paths. The first flow path includes receives a first reactant and includes a reactive flow path including a catalyst. The second flow path receives a second reactant source and is in operative fluid communication with the first flow path through a first barrier between the first and second flow paths that is permeable to the second reactant. The third flow path receives a fluid coolant.

    Abstract: An air separation system includes a high temperature ozone converter, a mechanical separator downstream of the high temperature ozone converter, and an air separator downstream of the mechanical separator. The air separator receives high temperature air and provides high temperature nitrogen-enriched air and high temperature oxygen-enriched air. The air separation system further includes a heat exchanger downstream of air separator that receives and cools the high temperature nitrogen-enriched air.

    Abstract: An air quality sensor includes a detector element array, a processor operatively connected to the detector element array, and a memory. The memory is disposed in communication with the processor and has instructions recorded on the memory that, when read by the processor, cause the processor to execute certain operations including measuring electrical resistance of one of more detector element of the detector element array. A difference is calculated between the measured resistance and a reference resistance, and a determination is made of presence or absence of a contaminant in air communicated to the detector element array from an atmosphere of an aircraft cabin based on the difference between the measured resistance and the reference resistance. Aircraft and methods of monitoring air quality also described.

    Abstract: Fibre optics for distributed environmental condition and/or air quality sensing such as, but not limited to, sensing air quality in enclosed areas of an aircraft such as the passenger cabin. Fibre optics can be used for sensing and for communication and are therefore well suited to the distributed sensing of environmental conditions such as temperature, relative humidity, gas and particulate composition within spaces of the aircraft e.g. the cabin, cargo space, cockpit, electronics bay etc. and in related systems such as the environmental control system (ECS), the cabin recirculation system, bleed air system etc.
