A rotor support includes a first ring disposed around a first axis, a second ring disposed around the first axis downstream from the first ring, and a plurality of beams extending between the first and the second rings. Each beam is configured to provide an axial stiffness, when an axial force is exerted on the first ring, and a radial stiffness, when a radial force is exerted on the first ring. Each beam has a height extending parallel to a second axis and a width extending parallel to a third axis. The beams are distributed around the first ring to provide a substantially uniform circumferential axial stiffness around the rotor support, and the height of each beam is greater than the width of each beam. Damping can be provided by the placement of a damper between the rotor support and the support housing.
