Abstract

1301002 Turbines; gas turbine plant; centrifugal compressors H BACHL 30 June 1970 [30 June 1969 15 July 1969 30 April 1970] 31726/70 Headings F1C F1G and F1T A rotor for a fluid-flow machine, e.g. a compressor or turbine, includes a series of flow ducts each extending between radially outer and inner ports and consisting of an outer region adjacent the outer port where the flow passage is shaped for predominantly tangential flow with a small axial component, an inner region adjacent the inner port where the passage is shaped for predominantly axial or axial and tangential flow, and an intermediate region in which the passage is shaped for predominantly radial flow, the outer port having a radially inner rounded-over edge formed by part of a circumferentially extending rim of the rotor whereby there is a direct transition adjacent the edge between the outer and intermediate regions. In one arrangement, Figs. 2, 3, the rotor is of centripetal type, having partition walls or vanes 3, the driving fluid entering substantially tangentially through circumferentially extending slot-like ports 9. A rapid change in flow to the radial direction is assisted by the shape of shroud 12 and by the rounded edge 15 of wall 14. In the inner region the flow is deflected into the axial direction with or without a tangential component and leaves through outlet ports 10 shaped as radial slots. To further assist direction change of the flow the vanes 3 may be curved-over at 16, 17 in the outer and inner regions respectively. In a modification, Figs. 5 to 12 (not shown) the outer ports 9 of the rotor are situated on a conical surface about the axis and the entering flow has an additional radially inward component. In a further modification, Fig.13, cooling or air compression ducts 26, 27 are situated above and below combustion gas expansion ducts 25, the latter being cooled by bled compressed air flowing through channels 35, 36, 37 in the partition walls. The compressed air leaving ducts 26, 27 passes through guide means 29, 30 and along path 42 to pre-heater 41 and thence to combustion chamber 38. Combustion gases leaving the latter are directed by means 28 into ducts 25 to drive the rotor. In any of the embodiments the plant may be multi-staged and may include stator flow ducts shaped to a mirror image of those in the rotor.
