Abstract: A method for startup of a catalytic oxidation unit includes flowing air from an air source into the catalytic oxidation unit, recycling air from an outlet of the catalytic oxidation unit to an inlet of the catalytic oxidation unit through a recycle duct, and flowing a fuel from a fuel source into the catalytic oxidation to cause a catalytic reaction.

Abstract: Fuel tank inerting and fire suppression systems and methods for an aircraft are provided. The systems include a fuel tank, a first reactant source fluidly connected to the fuel tank, the first source arranged to receive fuel from the fuel tank, a second reactant source, a catalytic reactor arranged to receive a first reactant from the first source and a second reactant from the second source to generate an inert gas that is supplied to the fuel tank to fill a ullage space of the fuel tank, and a fire suppression inert gas supply system arranged to direct the inert gas to a fire suppression system, wherein the fire suppression inert gas supply system includes a fire suppression inert gas supply controller to control a flow of inert gas to the fuel tank and the fire suppression system.

Abstract: Aircraft fuel tank inerting systems and methods are provided. The aircraft fuel tank inerting systems include a fuel tank having fuel therein, an evaporator container fluidly connected to the fuel tank and arranged to receive inerting fuel from the fuel tank, the evaporator container evaporating the inerting fuel to generate a first reactant, a second reactant source arranged to supply a second reactant, and a catalyst fluidly connected to the evaporator container and arranged to receive the first reactant and the second reactant, wherein the catalyst includes a catalyst material to induce a chemical reaction between the first reactant and the second reactant to generate an inert gas, wherein the inert gas is supplied into an ullage of the fuel tank.

Abstract: A system and method that comprises an air cycle machine, a flow of bleed air, at least one heat exchanger, and an inlet configured to supply the flow of the bleed air is provided. The bleed air directly flows from a source to mix with recirculated air downstream of a compressor of the air cycle machine in accordance with a high pressure mode or a recirculation chilling mode. The system and method can also utilize the recirculated air flowing from the chamber to drive or maintain the air cycle machine in accordance with the above modes.

Abstract: A system and method that comprises an air cycle machine, a flow of bleed air, at least one heat exchanger, and an inlet configured to supply the flow of the bleed air is provided. The bleed air directly flows from a source to either a compressor of the air cycle machine or the at least one heat exchanger in accordance with a high pressure, low pressure, or pressure boost operation mode. The system and method also can also utilize recirculated air flowing from the chamber to drive or maintain the air cycle machine in accordance with the above modes.
