Abstract
A module between a dihydrogen tank and an engine in an aircraft. The module comprises outer and inner boxes, a pipeline between the tank and the engine through the boxes, pressure limiters mounted on the pipeline and the inner box, an exhaust pipeline between the pressure limiters and the outside, shut-off valves mounted on the pipeline at the outer box, a detector for detecting a leak of the pipeline or of the outer box and a controller configured to control each shut-off valve as a function of the information delivered by the detector.

A module for a dihydrogen supply system for an aircraft comprising a dihydrogen tank and an engine, said module comprising:
- an outer box having an air inlet and an air outlet,
- a leak-tight inner box, inert and housed in the outer box,
- a pipeline configured to be fluidically connected between the dihydrogen tank and the engine, and passing through the outer box and the inner box,
- a device housed in the inner box and configured to act on the dihydrogen circulating in the pipeline,
- a first pressure limiter mounted on the pipeline in the inner box,
- a second pressure limiter mounted on the inner box,
- an exhaust pipeline fluidically connected between the first pressure limiter, the second pressure limiter, and the outside of the aircraft, in a mounted position of the module in the aircraft,
- an upstream shut-off valve mounted on the pipeline at the inlet of the pipeline in the outer box,
- a downstream shut-off valve mounted on the pipeline at the outlet of the pipeline in the outer box,
- detection means provided to detect a leak between the pipeline and the inner box or a leak between the inner box and the outer box and to deliver information representative of a leak, and
- a control unit configured to control an opening and a closing of each shut-off valve as a function of the information delivered by the detection means.
