An aircraft having at least one dihydrogen transport pipe, an embedding channel with a lower gutter, an aeration aperture with an air inlet collecting external air and at least one supply pipe opening at the air inlet, a control unit, and, for one or more lower gutters, a bypass box having, for each lower gutter, an inlet connected to the supply pipe and an outlet connected to the lower gutter, between each associated inlet and outlet, a door able to move alternately between an open position and a closed position, and, for each door, a maneuvering system controlled by the control unit and moving the door.

Aircraft having a dihydrogen transport pipe, an embedding channel for said transport pipe and an aeration system for said embedding channel

An aircraft with a dihydrogen transport line, an embedded channel having a gutter in which the transport line is fixed and having a first end by which the transport line enters into the gutter and a second end by which the transport line leaves the gutter, and an evacuation system fluidically connected between the second end of the gutter and the outside of the aircraft for the evacuation of air and of water.

Aircraft comprising a dihydrogen transport line, a channel for embedding said transport line and a system for evacuating air and water present in said embedded channel

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.

Casing system containing a heat exchanger for reheating dihydrogen

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.
