Rotor supports and systems

A rotating system for use in an engine, the system comprising:

• a rotor extending along an first axis;
• a bearing assembly mounted to the rotor;
• a support housing surrounding the bearing assembly;
• and
• a rotor support disposed between the support housing and the bearing assembly, the rotor support comprising:
• a first ring disposed around the first axis;
• a second ring disposed around the first axis and separated from the first ring;
• and
• a plurality of beams extending between the first and the second rings, each beam 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, wherein each beam has a height and a width, where the height is greater than the width, the height extending parallel to a second axis that is orthogonal relative to the first axis, the width extending parallel to a third axis that is orthogonal relative to the first axis and the second axis, wherein the beams are distributed around the first ring to provide a substantially uniform circumferential axial stiffness around the rotor support.
