    摘要: A journal bearing including a plurality of individual foils mounted to one of a pair of relatively rotatable members, and a plurality of undersprings which provide resilient support for the foils. The foils include a transition area defined for example by a step, adjacent the trailing edge of the preceding foil. The use of the stepped foil optimizes the geometry of the air gap profile, and thereby increases the load capacity of the journal foil bearing.

    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.
