A basic analytical model of a hybrid journal gas bearing was set up completely for investigating the coupling between aerodynamics and aerostatics in a hybrid gas bearing under incompressible conditions, and for further improving its performance, under incompressible conditions. In this analytical model, the load-carrying capacity function is composed of five items. Apparently, there are pressure coupling and structure coupling between aerodynamics and aerostatics and when the groove distribution coefficient is 0.36, it is approximately maximum. However, this type of hybrid gas bearing structure can not be used when the pressure ratio is less than 1. Review led by Bill Marscher
