Arthritis, in basic terms, entails joint inflammation. 27. The hydrostatic augmentation system of claim 25 wherein the compliant foil hydrodynamic fluid film journal bearing includes a cartridge having at least one generally arcuate axially extending cooling air cavity communicating with the interior of said cartridge.
It is, therefore, a principal object of the present invention to provide hydrostatic thrust load capacity augmentation for one side fixed profile bearing of a bilateral compliant foil hydrodynamic fluid film thrust bearing which supports a rotary machine having a compressor wheel.

The seat 18 is a radial recess provided on the inner surface 13 of the bearing housing 11 and has the shape of a parallelepiped having an opening on the inner surface 13, a plane base opposite to the opening and four plane lateral surfaces connecting the plane base to the opening.
The squeeze film gas bearing has similarities with the externally pressurised gas bearing (EP), an example of which was discussed in Section 5.6. Like the hydrodynamic bearing (or aerodynamic bearing for gases), all three types depend on viscous retardation within the film.
However, to provide adequate bearing compliances for overall load capacity and damping of disturbances to the runner, the spring is required to possess a lower spring rate, yet such a lower spring rate militates against maintenance of proper wedge shape and risks contact between the runner and foils under operating conditions, thereby risking damage to those members and failure of the bearing.

This invention relates generally to hydrodynamic fluid film thrust bearings and more particularly to such bearings employing one or more foils to establish and maintain a fluid film within the bearing and a resilient backing member accommodating deflections of the foil and excursions of the rotating portion of the bearing.
1. A fluid bearing for a wind turbine comprising: a bearing housing, a plurality of bearing pads inside the bearing housing and circumferentially distributed around a longitudinal axis of the fluid bearing, a plurality of supporting structures, each supporting structure having at least a first interface detachably connected to a respective seat provided in the bearing housing and at least a second interface detachably connected to a respective bearing pad of the plurality of bearing pads, wherein each supporting structure allows tilting of the respective bearing pad with respect to the bearing housing.
