摘要： 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.

摘要： Fire suppression systems for aircraft include an air source, a first ASM configured to generate inert gas from air from the air source and supply inert gas to a fuel tank, and a second ASM configured to generate inert gas from the air from the air source and supply inert gas to a protected space of the aircraft. The second ASM comprises a membrane having inherent microporosity. A controller, in operable communication with the ASMs, is configured to operate the first ASM and not the second ASM during a first state of operation, and in response to a fire detected in the protected space, operate the second ASM to supply an inert gas from the second ASM to the protected space in a second state of operation.

摘要： Systems and methods for generating inerting gas on vehicles are described. The systems include a proton exchange membrane (PEM) inerting system, a pure water replenishment system configured to provide pure water to the PEM inerting system, wherein the pure water replenishment system is in fluid communication with the PEM inerting system to replenish water lost during operation of the PEM inerting system, and a control system configured to control operation of the pure water replenishment system to automatically replenish pure water to the PEM inerting system.

摘要： A battery thermal management system for an air vehicle includes a liquid heat exchange circuit. The system includes at least one battery in thermal communication with the liquid heat exchange circuit. The system includes a controller operatively connected to the liquid heat exchange circuit. The controller is configured and adapted to variably select whether heat will be rejected to the liquid heat exchange circuit. The system includes at least one heat exchanger positioned on the liquid heat exchange circuit. The at least one heat exchanger is a liquid-air heat exchanger or a liquid-liquid heat exchanger. A method for controlling a thermal management system for an air vehicle includes determining an expected temperature of at least one battery, and cooling the at least one battery with a cooling device if the expected temperature exceeds a pre-determined expected temperature threshold.

摘要： 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.

摘要： A system and method for inerting a fuel tank is disclosed. A fluid including non-condensable gas is directed from a vapor space in the fuel tank to a suction port of an ejector, and a motive fluid is directed to a motive fluid port of the ejector. The motive fluid and the non-condensable gas fluid are combined in the ejector and are directed from an outlet port of the ejector to the fuel tank. An inert gas is provided to the ejector motive fluid port, or to the second flow path, or to the first flow path.

摘要： A system and method for inerting a protected space is disclosed. According to the method, 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 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 pressure differential is applied between the process water fluid flow path and a discharge side of the gas outlet to remove gas from the process water. Air is delivered to the cathode and oxygen is reduced at the cathode to generate oxygen-depleted air, which is directed from the cathode along an inerting gas flow path to the protected space.

摘要： A system is disclosed for treating a biologically active surface or material and inerting a protected space. Water is delivered to an anode of an electrochemical cell with the anode and a cathode separated by a proton transfer medium separator. A voltage difference is applied between the anode and the cathode to electrolyze water at the anode to form a mixture of protons and ozone. The protons are transferred across the separator to the cathode, and air is delivered to the cathode where oxygen is reduced to generate oxygen-depleted air, which is directed to the protected space. The ozone is transferred to an ozone storage or distribution system, and ozone is transferred from the ozone storage or distribution system to the biologically active surface or material.

摘要： An inert gas generating system includes a source of a liquid hydrocarbon fuel, and a fractioning unit configured to receive a portion of the liquid hydrocarbon fuel from the source. The fractioning unit includes a perm-selective membrane configured to separate the portion of the liquid hydrocarbon fuel into substantially sulfur-free vapors and a sulfur-containing remainder. The system further includes a catalytic oxidation unit configured to receive and react the substantially sulfur-free vapors to produce an inert gas.

摘要： A method of producing inert gas uses an electrochemical gas separator with a proton exchange membrane to produce oxygen-depleted air and a water vapor transport module to dehumidify oxygen-depleted air. A drying mechanism is leveraged in conjunction with the water vapor transport module to dry the oxygen-depleted air. The dried oxygen-depleted air is then used in a location requiring inerting.
