<p>A compressible fluid compressor/turbine rotor has a disc (12) with radial vanes (16, 18) extending outward to the disc rim (14) and axial flow turbine blades (22) extending radially outward beyond the rim. The fluid to be compressed enters a compressor stator sector through the compressor inlet (28) that is located between the shaft and the rim. It then flows radially outward, guided by the rotor vanes, where some compression occurs. The fluid continues to flow radially outward over the turbine blades, cooling them in the process. Finally, the fluid enters the diffuser vanes (34) in the compressor stator sector where compression of the fluid is completed. The fluid may pass through one or more such compression stages including interstage cooling. The fully compressed fluid then is heated by the system heat source and is returned to a turbine stator sector, through stationary turbine nozzles, and passes over the rotating turbine blades delivering power to the rotor (36). These gases may then pass to other turbine stages and to other components in the system, if any, and then to the atmosphere.</p> |
