Abstract:

An externally-pressurized gas thrust bearing was analyzed for both static and dynamic characteristics. The bearing is fed through an inherently compensated restrictor into a shallow pocket. The analysis gave special attentions to the significance of the recent finding of restrictor flow, the trade-off consideration between static stiffness and stability margin, and the effects of the pocket depth.
