摘要： A fuel supply circuit for an aeronautical cryogenic turbomachine including: at least one cryogenic reservoir containing a liquid fuel topped with a boil-off gas and including a high-pressure liquid pump to supply at least one main propulsion device of the turbomachine with liquid fuel, an auxiliary turbomachine including an electric generator, a gas compressor to supply the auxiliary turbomachine with gaseous fuel, and a buffer gas reservoir connecting the gas compressor to the cryogenic reservoir to reinject gas into the cryogenic reservoir in order to maintain the pressure in the cryogenic reservoir above a predefined value, the electric generator supplying the high-pressure liquid pump and the gas compressor.

摘要： The invention relates to the field of cryogenics, and in particular to a device and a method for chilling down a cryogenic system (1). The chilldown device (100, 101) comprises a cryogenic fluid feed circuit (102, 103) and at least one atomizing nozzle (110) connected to said feed circuit (102, 103). The chilldown method includes feeding cryogenic fluid via a feed circuit (102, 103) to at least one atomizing nozzle (110) connected to the feed circuit (102, 103), spraying the cryogenic fluid through the at least one atomizing nozzle (110) as a spray (200) of cryogenic fluid, and projecting the spray (200) of cryogenic fluid against at least one zone to be cooled in the cryogenic system (1).
