Application: Liquid Hydrogen Turbopump Vulcain space launcher

The cryogenic engines of the Vulcain space launchers has been subjected to increasingly severe operating conditions so that entirely new bearings were developed for the liquid hydrogen turbopumps. The principal axes of development, except the optimization of the bearing geometry, were related to the improvement of the mechanical properties of the X105CrMo17 steel (AISI 440C)…
