Abstract: A casing system mounted between an upstream solenoid valve of an upstream pipe and a downstream solenoid valve of a downstream pipe and which has a casing divided by a separation wall into a first volume which is placed under reduced pressure and a second volume, a heat exchanger which is fixed inside the casing with a first inlet which is arranged in the first volume and which is connected to the upstream pipe and a first outlet which is arranged in the second volume and which is connected to the downstream pipe, and a control unit which closes the solenoid valves if the deviation between two successive values of the pressure in the first volume or in the second volume is greater than a threshold.

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.
