Abstract: A method for combined cooling and heating in an aircraft, the aircraft including an engine configured to use dihydrogen as fuel, the dihydrogen being stored in liquid form in a tank and being used in gas form in the engine, the dihydrogen being conveyed from the tank to the engine by a main pipe. The method includes the steps of branching off a part of the flow of dihydrogen in a bypass pipe, in parallel with a predefined segment of the main pipe, circulating a first heat transfer fluid in a first closed circuit, carrying out a first heat exchange between the first heat transfer fluid and the dihydrogen circulating in the bypass pipe and carrying out at least one secondary heat exchange. Each secondary heat exchange is carried out between the first heat transfer fluid and a working fluid used in the aircraft which needs to be cooled.

Abstract: A system for recovering gaseous dihydrogen produced in a distribution duct arranged between a main tank and a dihydrogen consumer device, the distribution duct comprising a pump. The system comprises: an auxiliary tank; a bypass duct, arranged between the distribution duct and the auxiliary tank, downstream of the pump; a valve arranged on the bypass duct; a module for obtaining a temperature of the dihydrogen in the distribution duct, upstream of the pump. A control module of the valve opens the valve when the temperature is greater than a predetermined value and closes the valve when the temperature is less than or equal to the predetermined value.

Abstract: A device for cooling an aircraft propulsion system, including at least one cooling circuit with at least one air inlet equipped with an intake flap mobile between closed and open positions and at least one air outlet equipped with an exhaust flap mobile between closed and open positions, and at least one actuator coupled by at least one kinematic system to the pair of intake and exhaust flaps in such a manner that the intake and exhaust flaps are driven in synchronized movements and simultaneously occupy the closed position or the open position. This solution enables reduction of the number of actuators and, finally, the all-up weight of the aircraft.
