A system to hydrostatically augment the thrust load capacity of a bilateral compliant foil hydrodynamic fluid film thrust bearing for a turbomachine is disclosed. A plurality of channels and fixed orifices are provided in the bearing thrust plate to deliver and regulate compressor bleed air flow to the compressor side of the bilateral compliant foil hydrodynamic fluid film thrust bearing which includes additional channels and orifices to direct the bleed air against the bearing rotor thrust disk. After impinging on the rotor thrust disk, the bleed air fl...
[ What we claim is:] [1.] A hydrostatic augmentation system for a bilateral compliant foil hydrodynamic fluid film thrust bearing used in a turbomachine, said turbomachine having a compressor and a turbine on a common bearing rotor rotatably supported by a compliant foil hydrodynamic fluid film journal bearing and a bilateral compliant foil hydrodynamic fluid film thrust bearing acting upon a bearing rotor thrust disk, said hydrostatic augmentation system comprising:means to deliver bleed air from said compressor to the compressor side of said bilateral ...
