Designing Aerostatic Bearing With Counterbalancing Gaps for Lifting a Heavy Payload
TL;DR: In this article, an aerostatic bearing is designed for supporting a heavy payload, which involves an axial gap on the stator top that provides an upward lift, a bottom gap for counterbalancing the tendency of large lift-off, and a feeding orifice at the bearing inlet that is connected with the gaps by a network of holes or inherences yielding the damping.
