Abstract
A bearing for the ceramic rotor of a turbine engine or turbomachine, which consists of an air-supported bearing providing for a lubricating air film between the inner and outer bearing rings at least at the higher operating speeds of the engine. This facilitates operation of the turbine engine or machine under high temperature and rotational speed operating conditions.
