This paper describes the analysis, design, and testing of a one-piece hydrodynamic thrust bearing with an initially flat surface, which has a performance similar to conventional pivoted pad thrust bearings. The leading portion of each pad is undercut allowing it to deflect elastically under load and form a wedge-shaped film. Analysis of the configuration used is particularly simple and gives good agreement with experimental results. This cantilever bearing is compared quantitatively with the plain land type and is shown to have a greatly superior performance. Comprehensive instrumentation mounted in both the rotor and the bearing gave an accurate account of the operating conditions.
