摘要:
A turbopump which operates at cryogenic temperatures to pump cryogenic liquid fuels to high pressure, and which includes a rotating group supported on process fluid foil journal bearings and a hydrostatic and hydrodynamic foil thrust bearing. A back-face surface of a pump rotor reacts thrust forces to the foil thrust bearing and receives counter acting hydrostatic fluid forces dynamically moderated to achieve an equilibrium axial position and force balance.
