Abstract

742,242. Elastic-fluid turbines. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Feb. 15, 1952 [Feb. 15, 1951], No. 3705/51. Class 110(3) In an elastic fluid turbine having a rotor provided with one or more cooling passages, the cooling fluid is supplied to a tangential entry in a member formed with an annular cavity surrounding the rotor axis at the inlet to one of the cooling passages. The rotor comprises discs 1, 2. 3 interconnected at 5, 6 by screwed flanges and spaced apart to form cooling spaces 15, 16. The discs 1, 3 are carried on stub shafts 9, 10. A sleeve, 22 and an end disc 13 are mounted on the shaft 9, a cooling space 14 being formed between discs 1, 13. The shaft 9 is hollow and surrounds a tube 20 leading to space 16 and the annular space 21 between the bores of the shaft and the tube communicates with space 15. The shaft 9 or the interior of the sleeve is splined to provide passages 9a leading to space 14. The bore of the shaft or the exterior of the tube 20 may be similarly grooved. The member 24 forming an end cap of a bearing housing has annular cavities 24a, 24c communicating with space 21 and passages 9a. Cooling fluid is supplied to the cavities through tangential inlet bosses. Cooling fluid is also supplied to the tube 20. Passages 1a, 2a, 3a lead from the cavities to the blade roots. Discs 29 with radial ribs are arranged in the cooling spaces 14, 15, 16 to form radial passages which are lined with polished metal. Specification 742,241 is referred to.
