ABSTRACT
Although centrifugal compressors are slightly less efficient than axial-flow compressors, they are easier to manufacture and are thus sometimes preferred. Additionally, a single stage of a centrifugal compressor can produce a pressure ratio of 5 times that of a single stage of an axial-flow compressor. Thus, the centrifugal machine finds application in ground-vehicle power plants, auxiliary power units, and other small units.
