1. An aircraft comprising:
at least one transport pipe in which dihydrogen flows,
for each transport pipe, an embedding channel having a gutter that has a bottom, an opening opposite the bottom, and a perforated intermediate floor between the bottom and the opening that separates the gutter into an upper gutter in which the respective transport pipe is fastened and a lower gutter,
an aeration system having an aeration aperture having an air inlet arranged to collect air outside the aircraft and at least one supply pipe wherein each supply pipe opens at said air inlet via a window,
detection means distributed in each embedding channel and arranged to detect a presence of dihydrogen,
wherein each lower gutter comprises a bypass box having:
for each of said lower gutters, an inlet fluidically connected to the at least one supply pipe and an outlet fluidically connected to said lower gutter, wherein the inlet and the outlet are fluidically connected to one another by a duct, wherein the inlet is different for each lower gutter,
between each associated inlet and outlet, a door configured to move alternately between an open position in which the air is free to circulate between the inlet and the outlet and a closed position in which the air is blocked between the inlet and the outlet, and
for each door, a maneuvering system arranged to move said door alternately from the open position to the closed position, and
a control unit arranged to receive information from the detection means and control each maneuvering system on a basis of said information.
