摘要： A sparging evaporator for an inerting system including an outer vessel, an inner vessel within the outer vessel, and a plenum formed between the inner and outer vessels. The outer vessel includes a gas inlet for receiving inlet gas into the plenum, and a liquid inlet for receiving liquid fuel into the plenum. The inlet gas in the plenum generates a gas pressure that is exerted against a free surface of the liquid fuel in the plenum thereby forcing the liquid fuel and the inlet gas through an inlet of the inner vessel. The inner vessel contains a lattice structure that promotes liberation of fuel vapor from the liquid fuel and enables the inlet gas in the liquid fuel to sparge the fuel vapor in the liquid fuel, thereby forming a fuel-enriched gas mixture that can be fed to a reactor of the inerting system.

摘要： An aircraft including at least one hydrogen engine, at least one hydrogen supply device including at least one hydrogen tank and at least one item of equipment through which the hydrogen flows and which is positioned between the hydrogen tank and the hydrogen engine. The aircraft includes at least one sealed container sealed from the outside air, in which sealed container the equipment of the hydrogen supply device is positioned. This solution allows a safe hydrogen installation to be obtained using existing equipment.

摘要： A gas distribution system for aircrafts includes a corrugated hose having a first connecting end and a second connecting end, and a shroud surrounding the corrugated hose concentrically along a longitudinal direction of the corrugated hose, thereby building an intermediate space between the corrugated hose and the shroud. The first connecting end is configured to be connected to a gas tank. The second connecting end is configured to be connected to a gas consumer. The corrugated hose is flexible so as to compensate for in-flight deflections of the gas distribution system. Also, an aircraft including a fuselage, a Hydrogen consumer, a Hydrogen tank, and the gas distribution system is provided. The gas distribution system fluidly connects the Hydrogen tank with the Hydrogen consumer.

摘要： A hydrogen fuel including a safety marker and a method and apparatus for adding the safety marker to the hydrogen fuel. The hydrogen fuel may be stored in a tank in a liquid phase and then heated to at least one of a gaseous phase and a supercritical phase. The safety marker may be added to the hydrogen fuel when the hydrogen fuel is in the at least one of the gaseous phase and the supercritical phase after heating the hydrogen fuel. The hydrogen fuel may be delivered in the at least one of the gaseous phase and the supercritical phase to a power generator, such as a gas turbine engine. The safety marker may be a visual safety marker, such as a noble gas, or an odorant.

摘要： An inerting system for a fuel tank containing a liquid fuel and an ullage gas. The inerting system includes a fluid circuit connectable to the fuel tank, an evaporator connected in the circuit, and a reactor connected in the circuit downstream of the evaporator. The evaporator receives a flow of the liquid fuel from the fuel tank and volatilizes at least a portion of the liquid fuel to thereby form a volatilized fuel vapor. The evaporator also receives a flow of the ullage gas from the fuel tank, and permits the ullage gas to sweep away the volatilized fuel vapor downstream with the ullage gas to thereby form a fuel enriched gas mixture containing the ullage gas and the volatilized fuel vapor. The reactor converts at least some of the fuel enriched gas mixture into a non-flammable gas. The circuit supplies at least some of the non-flammable gas to the fuel tank.

摘要： A device for evaporating a liquid such as liquid fuel. The device comprises: a shell; means for supplying heat to the shell; a porous wick located in the shell so that there is a gap between an outer surface side of the porous wick and an inner surface of the shell; means for supplying liquid to the porous wick; and an outlet in the shell for vapour produced in the gap by the application of heat from the shell to the liquid in the wick.

摘要： An apparatus contains a dihydrogen tank and/or a dihydrogen circuit, and a device for regulating a concentration of dihydrogen located outside the tank and/or the circuit. The device includes at least one pair of electrical conductors including a first electrical conductor supplied with a first voltage and a second electrical conductor supplied with a second voltage which is different from the first voltage. At least one controller repeatedly commands the application of a predetermined voltage difference between the first electrical conductor and the second electrical conductor so that an electric arc of controlled power is formed in order to burn dihydrogen possibly coming from the tank and/or from the circuit. Thus, dihydrogen does not accumulate in undesired places in the apparatus.
