Title: Bearing support structure combining fluid damping and spring damping apparatus

Abstract: A bearing support structure capable of reliable operation in a rotary machine is disclosed. Various construction details which enable the damping of vibratory energy are discussed. Fluid damping and spring damping apparatus are combined in forming an effective structure for damping synchronous and non-synchronous vibratory energy. The system is built around a plurality of arcuate beams which effect spring damping, and which collaterally form chambers for the containment of a fluid damping medium.
