Experimental and CFD analysis of a gas-lubricated foil thrust bearing for various foil configurations [PDF]
FME Transactions, 2023 Thrust foil bearings operating at hydrodynamic conditions are self-acting (aerodynamic) bearings that support high-speed shafts at mild loading conditions with air as a lubricant and are generally used in low-power gas turbines.

Static Analysis of Viscoelastic Supported Gas Foil Thrust Bearing with Journal Inclination
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010 Thrust pads in rotary machines are often used to bear the axial load, sometimes part or whole of the rotor weight is also sustained by thrust pads when the machine is not installed horizontally.

A Review on Performance Characteristics of an Air Foil Thrust Bearing
Tribology Online, 2022 The axial loads of high-speed rotating turbo machines are supported by self-acting hydrodynamic components known as air foil thrust bearings (AFTB). The load bearing capability of these bearings depends primarily on the foil structure and secondarily on ...
