1. A hydrodynamic foil gas bearing assembly (21, 22, 23, 24, 30, 35, 36, 37, 40, 41, 42, 45, 46, 47, 50, 52) suitable for supporting a rotatable shaft (7, 14, 18, 43, 49, 53) therein, wherein the hydrodynamic foil gas bearing assembly (21, 22, 23, 24, 30, 35, 36, 37, 40, 41, 42, 45, 46, 47, 50, 52) comprises:
a. two conical rotor elements (3, 4, 10, 11, 16, 17, 31, 32), each having a small circular end and a large circular end; and b. at least two foil bearings (21, 22, 23, 24, 30, 35, 36, 37, 40, 41, 42, 45, 46, 47, 50, 52) having at least one compliant component (22, 36, 45) and at least one top foil (24, 42, 47) positioned atop the at least one compliant component (22, 36, 45), in which the conical rotor elements (3, 4, 10, 11, 16, 17, 31, 32) make end-to-end contact when placed upon the rotatable shaft (7, 14, 18, 43, 49, 53) disposed within the hydrodynamic foil gas bearing assembly (21, 22, 23, 24, 30, 35, 36, 37, 40, 41, 42, 45, 46, 47, 50, 52) and in which the ends of the conical rotor elements (3, 4, 10, 11, 16, 17, 31, 32) which are in contact are of the same size. |
