Abstract: 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.

Abstract: An aircraft having at least one transport pipe in which dihydrogen flows and, for each transport pipe, an embedding channel in which the transport pipe is housed. The embedding channel has a gutter that has a bottom and an opening opposite the bottom and a cover that covers the opening of the gutter. The cover constitutes an outer wall of the aircraft in direct contact with external air surrounding the aircraft. The cover has ventilation windows passing through it that allow the passage of the dihydrogen towards the outside. With such an arrangement, even in the event of dihydrogen leaking into the embedding channel, the dihydrogen is automatically evacuated towards the outside of the aircraft.

Abstract: An aircraft with a wing attachment connecting the wings and the fuselage of the aircraft and having first and second parts positioned on either side of the median longitudinal plane of the aircraft. Each first or second part comprises at least one vertical connection configured to transmit substantially vertical forces between one of the wings and the fuselage, and first and second oblique connections each having at least one first or second oblique rod that has a first end connected to the fuselage structure and a second end connected to the wing structure, the second ends of the first and second oblique rods being further apart than their first ends.

Abstract: An aircraft comprising a fuselage, first and second wings positioned on either side of the fuselage, wherein each wing includes an inner part connected to the fuselage and an outer part continuing the inner part, the end of each inner part connected to the fuselage having a height greater than half the height of the fuselage and extending over a length greater than or equal to half of a distance separating the nose and the tail of the fuselage.

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 having a fuselage having a pressurized upper space above the floor and a lower space beneath the floor, a wing, a hollow support stay fixed between the lower space level of the fuselage and the wing, an electric motor propeller propulsion system fixed beneath each wing, the output shaft of the motor driving a propeller in rotation, a production system having a fuel cell producing electrical energy supplying the electric motor with electricity via electrical conductors, a hydrogen reservoir fixed in the lower space, and a hydrogen inlet pipe feeding hydrogen from a hydrogen reservoir to the production system, wherein the hydrogen inlet pipe extends through the interior of the support stay. The electrical conductors or the hydrogen pipes pass through the stays on the outside of the fuselage and therefore at a distance from the passengers and the electronic systems of the aircraft.
