The axial loads of high-speed rotating turbo machines are supported by self-acting hydrodynamic components known as air foil thrust bearings (AFTB). load bearing capability these depends primarily on the structure and secondarily operating conditions. present review enlightens tribological performance parameters said in enhancing carrying capacity. Various design fabrication methods including t...

Ground-based testbeds play a critical role in developing and testing different methods of spacecraft dynamics control. To find the dynamic behavior such an air-bearing testbed, detailed characterization testbed must be provided via systematic approaches. This paper describes planar to develop control on-orbit operations. has almost frictionless surface can used simulate two-dimensional motions ...
