Abstract: We have studied a self-regulating radial gas-dynamic bearing and developed a methodology for its calculation and design. We have also developed modeling methods for rotational segments of the bearing surface stable in terms of rotation angle, load and rotor speed. There was developed a numerical method for determining the position of a segment with zero moments as well as the method of analyzing its stability in this position. This study describes a technique to determine the stable equilibrium position of a segment. We have determined the values and directions of a torque and the resultant forces for different values of the average thickness of the lubricating layer and the shaft speed. There were obtained the pressure plots in the lubricating layer of the segment. We have defined the parametric dependences of design characteristics of the bearing on the load and on the rotational speed of the shaft. Practical srelevance. The developed calculation technique can be used in designing hybrid air bearings while selecting the position of a segment rotation axis. Segment rotation allows the range of self-regulation of air bearings to be extended and in certain limits to parry the overloads on the shaft.
