摘要

Air Liquide has been involved since the end of the seventies in Space activities for thedevelopment of cryogenic equipment for rocket launching pads (Kourou for Ariane 4 and 5)and ground test benches (for thrusters, satellites,..).Recently, Air Liquide has been in charge of the upgrade of the cryogenic installations of theELA3 launching pads in Kourou for the latest version of ARIANE 5 launcher. An overview oftheses activities will be briefly presented.The use of subcooled (densification) propellant allows to increase the capacity of a launcher.Air Liquide has provided a specific liquid oxygen subcooling for a Vinci thruster bench atSNECMA. Process design and test results will be detailed.The use of Xenon electrical propulsion thruster is a recent development in satellitestechnologies. Air Liquide has developed an original mobile high pressure (up to 150 bar)cryogenic thermal compressor for the filling of Xenon tanks on board satellites. Air Liquidealso developed large pumping capacity cryopumps for Xenon trapping in thrusters testchambers. This specific development will be presented.
