Abstract: An aircraft including a fuselage, a wing structure, at least one turbomachine running on hydrogen and generating thrust at a propulsion unit distant from the fuselage, at least one fuel tank positioned in the fuselage and configured to store hydrogen in the cryogenic state, at least one hydrogen supply device connecting the fuel tank and the turbomachine and including at least one pump positioned in the fuselage in the vicinity of the fuel tank, at least one hydrogen heating system positioned in the fuselage in the vicinity of the pump. This solution makes it possible to reduce a length of the complex double-walled pipes configured for carrying the hydrogen in the cryogenic state between the fuel tank and the hydrogen heating system.

Abstract: An aircraft with at least one engine system, at least one zone for ejection of debris originating from the engine system and at least one fluid supply circuit. The latter comprises a shutter configured to occupy open and closed states, at least one return element configured to push the shutter to the closed state and at least one control positioned at least partially in the ejection zone and configured to hold the shutter in the open state against the return element. When the control is broken in the case of an accident, it no longer holds the shutter, which switches automatically to the closed state.

Abstract: A module between a dihydrogen tank and an engine in an aircraft. The module comprises outer and inner boxes, a pipeline between the tank and the engine through the boxes, pressure limiters mounted on the pipeline and the inner box, an exhaust pipeline between the pressure limiters and the outside, shut-off valves mounted on the pipeline at the outer box, a detector for detecting a leak of the pipeline or of the outer box and a controller configured to control each shut-off valve as a function of the information delivered by the detector.

Abstract: A propulsion assembly having a propulsion system including an exhaust nozzle fastened to the nozzle wall on the outside thereof so as to define between them a chamber, and a heat exchanger system ensuring an exchange of heat energy between the hot combustion gases circulating in the exhaust nozzle and the colder fuel circulating in the supply pipe at least in part by thermal radiation through the nozzle wall. The heat exchanger system has a pipe portion arranged in the chamber and the exchange of heat energy takes place at this pipe portion. With such an arrangement, the heat energy of the combustion gases is transferred to the fuel for better combustion.

Abstract: A heat exchanger including a sealed housing and a body positioned inside the housing, the body including a stack of least one first assembly of first and second plates pressed against each other, between which flows a first fluid, and at least one second assembly of third and fourth plates pressed against each other, between which flows a second fluid, the first and second assemblies being arranged so that they transfer heat between the first and second fluids. This configuration limits the risk of leaks and mixing of the two fluids.
