Abstract

988,541. Gas turbine rotor cooling. RUSHTON & HORNSBY Ltd. Jan. 4, 1963 [March 6, 1962], No. 8518/62. Headings F1G and F1T. The rotor and blade roots of an axial flow gas turbine having blade carrying discs spaced axially apart by rotating sealing rings secured therebetween are cooled by fluid passing through passages between the discs and sealing rings to an area in the region of the blade roots enclosed by annular plates on either side of each disc, the plate on the interstage side of each disc being located at its radially outer edge by the blade platforms and at its radially inner edge by an extension on the interstage sealing ring. An axial flow gas turbine has rotor discs 11, 12 carrying blades 13, 14 separated by a sealing ring 15 attached to the discs. The upstream and downstream rims of discs 11, 12 are enclosed by annular plates 25, 26 respectively, retained between blade platforms 19, 20 and slots in the disc rims. The interstage rims of discs 11, 12 are enclosed by annular plates 27, 28 secured to blade platforms 19, 20 by circlips 29, 30 and engaging extensions 32, 33 on sealing ring 15. Plates 27, 28 may be tapered radially outwards and may be locked to ring 15 by dowels. Cooling fluid flows respectively through passages 34, 36 to space 38 from which it exhausts through holes 37, 39 and through passages 35, 40 to exhaust through holes 41, 42. The blades 13, 14 may also have internal cooling passages. In a modification, Fig. 2 (not shown), the sealing ring has additional cooling passages and the interstage annular plates are split and not retained by circlips.
