A rotor support (128) includes a first ring (160) disposed around a first axis (132), a second ring (162) disposed around the first axis (132) downstream from the first ring (160), and a plurality of beams (164, 166, 168, 170, 172) extending between the first and the second rings (160, 162). Each beam (164, 166, 168, 170, 172) is configured to provide an axial stiffness, when an axial force is exerted on the first ring (160), and a radial stiffness, when a radial force is exerted on the first ring (160). Each beam (164, 166, 168, 170, 172) has a height extending parallel to a second axis (176) and a width extending parallel to a third axis (180). The beams (164, 166, 168, 170, 172) are distributed around the first ring (160) to provide a substantially uniform circumferential axial stiffness around the rotor support (128), and the height of each beam is greater than the width of each beam. Damping can be provided by the placement of a damper (130) between the rotor support (128) and the support housing (134).
