ABSTRACT
The structure of an out-pump type thrust gas bearing was described, and an analytical model was developed under completely incompressible condition. The objectives were to investigate the coupling between aerodynamics and aerostatics in a complex thrust gas bearing and to improve the performance of the bearing. The model showed that the load-carrying capacity had five parts to it and that apparently there were pressure coupling and structure coupling between aerodynamics and aerostatics. The surface feature function was identically positive: it increased the load-carrying capacity greatly. There was also no limit regarding the pressure ratio—when the pressure ratio was 0, the load-carrying capacity increased to about 25%.
