Abstract: A system and method for providing inerting gas to a protected space is disclosed. The system includes an air separation module that includes an air inlet, a membrane with a permeability differential between oxygen and nitrogen, a nitrogen-enriched air outlet, and an oxygen-enriched air outlet. The system also includes an air flow path between an air source and the air separation module inlet, and an inerting gas flow path between the air separation module nitrogen-enriched air outlet and the protected space.

Abstract: A method of fuel tank inerting includes separating process air into nitrogen-enriched air and oxygen-enriched air with an air separation membrane. A vacuum is applied to the air separation membrane to produce a pressure differential across the air separation membrane. The vacuum is manipulated to vary the pressure differential and vary purity of the nitrogen-enriched air.

Abstract: A system and method for inerting a protected space is disclosed. Process water is delivered to an anode of an electrochemical cell comprising the anode and a cathode separated by a separator comprising a proton transfer medium. A portion of the process water is electrolyzed at the anode to form protons and oxygen, and the protons are transferred across the separator to the cathode. Process water is directed through a process water fluid flow path including a gas outlet and a gas discharge valve in operative fluid communication with the gas outlet. Air is delivered to the cathode and oxygen is reduced at the cathode to generate oxygen-depleted air, and the oxygen-depleted air is directed from the cathode of the electrochemical cell along an inerting gas flow path to the protected space.

Abstract: A battery thermal management system for an air vehicle includes a liquid heat exchange circuit, an air heat exchange circuit, and a liquid-air heat exchanger. The liquid-air heat exchanger is positioned on the liquid heat exchange circuit and the air heat exchange circuit to exchange heat therebetween. The system includes a coolant pump fluidically connected to the liquid heat exchange circuit, a flow restrictor positioned in the liquid heat exchange circuit, and a battery in thermal communication with the liquid heat exchange circuit. A method for controlling a thermal management system for an air vehicle includes sensing a temperature of a battery with a temperature sensor, varying a flow area of a flow path through a liquid heat exchange circuit with the flow restrictor if the temperature is below a pre-determined threshold, and operating a pump to provide heating to the battery if the temperature is below the pre-determined threshold.

Abstract: A system is disclosed for providing inerting gas to a protected space. The system includes an electrochemical cell comprising a cathode and an anode separated by a separator including a proton transfer medium. A supply of process water is provided to the anode, and inerting gas is produced at the cathode. A heat exchanger is in operative fluid and thermal communication with the process water, and a temperature sensor is in operative thermal communication with the cathode or the anode. A controller is configured to provide a target temperature of the temperature sensor through control of a flow rate of process water or a temperature of process water, or both a flow rate and a temperature of process water, through a process water thermal management flow path in operative thermal communication with the cathode or the anode.

Abstract: A battery thermal management system for an air vehicle includes a liquid heat exchange circuit, an air heat exchange circuit in selective fluid communication with ram air, a liquid-air heat exchanger positioned on the liquid heat exchange circuit and the air heat exchange circuit to exchange heat therebetween. The system includes at least one battery in thermal communication with the liquid heat exchange circuit. The at least one battery is configured to at least one of charge or discharge to heat the at least one battery above a pre-determined minimum battery temperature. A method for controlling a thermal management system for an air vehicle includes determining if at least one battery is within a thermal range of operation for heating. The method includes charging and/or discharging the at least one battery to heat the at least one battery if the at least one battery is within the thermal range of operation for heating.

Abstract: A method of selectively operating an ullage passivation system includes receiving at least one of a temperature signal and a vapor composition signal. The method further includes operating an ullage passivation system to provide a fluid to the fuel tank, in response to at least one of a temperature exceeding a temperature threshold and a component of the vapor composition exceeding a threshold composition.

Abstract: A system for generating inert gas includes a source of pressurized air. An air separation module including at least one permeable membrane is operable to separate the pressurized air into oxygen-enriched air and inert gas-enriched air. A fuel tank containing a fuel is arranged downstream from said air separation module. The inert gas-enriched air output from said air separation module interacts with said fuel to remove dissolved oxygen from said fuel.

Abstract: A fuel tank inerting system uses a catalytic oxidation unit to combust fuel from the fuel tank to produce inert gas, simultaneously working with a gas separator that removes dissolved carbon dioxide from the fuel before it is cycled to the thermal management system (TMS) or the engine. This prevents cavitation of carbon dioxide (gaseous bubbling) within the fuel at varying temperatures while in flight.

Abstract: An air inert gas generating system consists of heat exchangers, a heating element, and a plurality of solid oxide electrochemical gas separator (SOEGS) cells. The SOEGS cells are interconnected in series to create a stack. A voltage is applied to the stack causing oxygen ions to be transported from the air flowing through the cathode through the electrolyte to the anode side of the SOEGS, resulting in oxygen-depleted gas. The oxygen-depleted gas can be used to inert the ullage of aircraft fuel tank or support the fire suppression system in the cargo hold. The oxygen-enriched gas can be used for other purposes.
