Optimum Design of Multiple-Hole Inherently Compensated Air Bearings—Part 1: Circular Thrust Bearings

Analyses of inherently compensated hydrostatic gas bearings of three types are presented. The flow model incorporates empirically the partial recovery of the dynamic pressure in the entrance region. Conditions leading to maximum normal stiffness or/and load are given for air. Analytical results are compared with experimental measurements. Circular thrust bearings are discussed in this article. Subsequent papers will deal with collar thrust and journal bearings.
