An apparatus and method that provides a flexible anisotropic support, which may accommodate open, closed, or re-circulating squeeze film damper (15) in parallel, has improved internal rolling element clearances (24), limits maneuver and blade loss responses by limiting rotor excursion, and has a rotor centering feature. This is accomplished through the combination of beam (25) and ring (16, 17) arrangement, which provides support anisotropy that produces beneficial cross-coupling stiffness for the support to control synchronous and non-synchronous vibration. |
