Superconductor current limiting device and aircraft comprising such a device

An aircraft, comprising:

• at least one electric motor powered using a cryogenic system, the cryogenic system including a superconductor current limiting device comprising:
• a leak-tight enclosure having two apertures arranged on opposite sides of the leak-tight enclosure and arranged to allow a circulation of a cryogenic fluid inside said leak-tight enclosure,
• a superconductor busbar passing through said leak-tight enclosure via two connection apertures, having a central part arranged inside said leak-tight enclosure such that the central part is surrounded by the cryogenic fluid circulating in the leak-tight enclosure, and a first and a second terminal parts respectively arranged on either side of said central part and in continuity of said central part and at least partially arranged outside of said leak-tight enclosure, and
• an inductor comprising a first pole and a second pole arranged inside the leak-tight enclosure and disposed facing the central part of the superconductor busbar,
• wherein the first pole of the inductor is electrically connected to the first terminal part of the superconductor busbar via a first connection link, and the second pole of the inductor is electrically connected to the second terminal part of the superconductor busbar via a second connection link.
