ABSTRACT:
A hydrostatic bearing support for a rotor includes a bearing, and a mounting for the bearing affording a clearance space between the rotor and the bearing. A hydrostatic feed pocket is carried by the mounting for receiving a fluid under pressure and supplying the fluid under pressure into the clearance space to provide a fluid film between the bearing and the mounting. A pump supplies fluid under pressure to the pocket. A pressure fluctuation damper is disposed between the pump and the pocket enabling the fluid to provide a bearing support having simultaneously a low dynamic stiffness for damping rotor vibration and a high static stiffness for locating the bearing relative to mounting.
