A basic analytical model of the out-pump type complex journal gas bearing is set up to investigate the coupling mechanism between aerodynamics and aerostatics in a complex gas bearing and to improve its performance, under incompressible conditions. The analytical model shows that the load-carrying capacity function is composed of five items. Apparently, there is both pressure and structure coupling between aerodynamics and aerostatics; identically, the surface feature function is positive; and when the groove distribution coefficient is 0.30, it is approximately maximum.
