The invention discloses an ultrasonic aerodynamic bearing which comprises a bearing body (1). The ultrasonic aerodynamic bearing is characterized in that a plurality of piezoelectric vibrators (2) are evenly arranged on the bearing body in the circumferential direction and are connected with flexible tilting bush structures; each flexible tilting bush structure comprises a bearing bush (3) and a flexible supporting structure (4), wherein the bearing bush (3) is arranged on the inner side of the bearing body (1), and the bearing bush (3) is connected with the bearing body (1) through the flexible supporting structure (4); matching faces of the bearing and a rotating shaft (6) are formed by the inner surfaces of the bearing bushes (3). According to the ultrasonic aerodynamic bearing, by improving the structure of the bearing bushes in the circumferential direction, the load capacity, the operation stability and the impact resistance of the bearing are improved. Meanwhile, the structure of the inner surfaces of the bearing bushes is improved, so that the load capacity and the energy utilization efficiency of the bearing are improved.
