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: 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: A fuel tank inerting system is disclosed. The system includes a fuel tank and 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 a fuel flow path in operative communication with the fuel tank and oxygen from an oxygen source, and to catalytically react a mixture of the fuel and oxygen along the reactive flow path to generate an inert gas. An inert gas flow path provides inert gas from the catalytic reactor to the fuel tank. An adsorbent is disposed along the fuel flow path or along the reactive flow path.

Abstract: A method of making a heat exchanger uses a functionally graded polymer composite material to create the heat exchanger. The polymer composite material includes a polymer and a filler, the filler concentration is varied in each part of the heat exchanger, either within the part, creating a gradient, or is different in each part of the heat exchanger depending on use of that part of the heat exchanger.

Abstract: A system for processing recirculation air recovered from an aircraft cabin includes a mixing chamber and a carbon dioxide removal system. The carbon dioxide removal system has an inlet for recovered recirculation air from the aircraft cabin, an outlet to the mixing chamber; at least two assemblies of carbon dioxide sorbent that are thermally linked, a CO2 outlet valve; and a controller for managing desorption of carbon dioxide from the sorbent depending on aircraft status. The mixing chamber has an inlet from the carbon dioxide removal system, an inlet from an environmental control system, and an outlet connected to the aircraft cabin.

Abstract: A method is disclosed for removing ozone from a gas. According to this method, the gas is contacted with an adsorbent that includes a transition metal oxide or metal organic framework to form a treated gas. The treated gas is contacted with a noble metal catalyst to catalytically decompose ozone in the treated gas, thereby forming an ozone-depleted treated gas.
