Abstract: A cryogenic system configured to cool down components and including a housing and a thermal coupling system able to thermally connect a cryogenic fluid tank and the housing, the housing being airtight and being arranged to contain at least one component. The cryogenic system includes: an inert fluid tank, the inert fluid including at least one of the inert gas or nitrogen; a first opening connected to the inert fluid tank; a second opening connected to a relief valve configured to release gas from the housing when the pressure inside the housing exceeds a predefined pressure value; a third opening connected to an exhaust line, and a shut-off valve disposed on the exhaust line. The component is thus thermally and chemically isolated from the outside of the housing without using vacuum.

Abstract: Cooling architecture for a cryogenic and superconducting powertrain using liquid hydrogen on board and method for managing the cooling temperature of the powertrain components. The cooling architecture comprises at least one heat exchanger configured to transfer heat from a first fluid to a second fluid. The first fluid of each heat exchanger may be liquid hydrogen (H2), and the second fluid of each heat exchanger may be gaseous helium (He), liquid Neon or liquid Nitrogen (N2).
