1. A supply system for an aircraft, having a first dihydrogen tank, a second dihydrogen tank and an engine, the supply system comprising:
a supply module comprising a first outlet pipe, a second outlet pipe, a first feed pipe fitted with a first main pump and configured to be fluidically connected to the first dihydrogen tank, a second feed pipe fitted with a second main pump and configured to be fluidically connected to the second dihydrogen tank, and channeling means designed to channel the dihydrogen in the first feed pipe and second feed pipes alternatively towards the first outlet pipe, or the second outlet pipe or both,
an upstream pipe fluidically connected between the first feed pipe and second feed pipe,
a downstream pipe fluidically connected between the first outlet pipe and the second outlet pipe,
a first linking pipe that is fluidically connected between the upstream pipe and the downstream pipe, a second linking pipe that is fluidically connected between the upstream pipe and the downstream pipe, the first linking pipe and the second linking pipe being arranged fluidically connected in parallel one to the other,
a first sub-pipe that is fluidically connected between the first linking pipe and the second linking pipe, a second sub-pipe that is fluidically connected between the first linking pipe and the second linking pipe, the first sub-pipe and the second sub-pipe being arranged fluidically connected in parallel one to the other,
a first heater,
a second heater,
a distribution module comprising a first introduction pipe fluidically connected to the first outlet pipe via the first heater, a second introduction pipe fluidically connected to the second outlet pipe via the second heater, a first distribution pipe and a second distribution pipe that are configured to be fluidically connected to the engine, and channeling means for channeling the dihydrogen in the first introduction pipe and second introduction pipes alternatively towards the first distribution pipe or the second distribution pipe or both,
detection means configured to detect an incident in the supply module, the distribution module, the first heater and second heaters, or any combination thereof, and to provide information representative of the incident that was detected, and
a control unit configured to command the channeling means of the supply module, the channeling means of the distribution module, or both depending on the information provided by the detection means,
wherein the supply module further comprises:
a two-way first solenoid valve mounted on the first linking pipe between the upstream pipe and the first sub-pipe,
a first secondary pump mounted on the first linking pipe between the first solenoid valve and the first sub-pipe,
a two-way second solenoid valve mounted on the first linking pipe between the first sub-pipe and the second sub-pipe,
a regulating two-way third solenoid valve mounted on the first linking pipe between the second sub-pipe and the downstream pipe,
a two-way fourth solenoid valve mounted on the first linking pipe between the third solenoid valve and the downstream pipe,
a two-way fifth solenoid valve mounted on the second linking pipe between the upstream pipe and the first sub-pipe,
a regulating two-way sixth solenoid valve mounted on the second linking pipe between the fifth solenoid valve and the first sub-pipe,
a two-way seventh solenoid valve mounted on the second linking pipe between the first sub-pipe and the second sub-pipe,
a second secondary pump mounted on the second linking pipe between the second sub-pipe and the downstream pipe,
a two-way eighth solenoid valve mounted on the second linking pipe between the second secondary pump and the downstream pipe,
a two-way ninth solenoid valve mounted on the first sub-pipe, and
a two-way tenth solenoid valve mounted on the second sub-pipe.
