ABSTRACT:
A fluid dynamic machine has a single rotor providing the rotor portion of a centrifugal compressor and also the rotor portion of an axial-to-radial flow fan. The portion of the rotor blades adjacent the hub define a compressor blading and the axially forward part of each blade is extended outwardly to provide a fan blade. These are supplied from a common inlet eye, and the flow is split at the downstream side of the fan between the fan and compressor passages by a generally radial plate curving forwardly at its inner margin and providing the forward fixed shroud for the compressor blades. The fan diffuser is split in a generally diametrical direction.
