Abstract: An aerodynamic bearing has an inner surface defining a channel for receiving a shaft. The inner surface is deformable between a first position in which the inner surface is located at a first radial distance, and a second position in which the inner surface is located at a second radial distance. The second radial distance is greater than the first radial distance. The inner surface is formed of at least one of an elastomeric material and a plastic material.

Abstract: A compressor has a rotor assembly having an impeller for generating an airflow through the compressor, a stator core assembly for causing rotation of the impeller, and a diffuser assembly for acting on the airflow generated by the impeller. The diffuser assembly has a first diffuser stage and a second diffuser stage. The first and second diffuser stages are separate components connected to one another by a fastener.
