Abstract

623,615. Jet-propulsion gas turbine plant. MORLEY, F. W. W., and GARDINER, T. E. G. May 6, 1947, No. 12268. [Class 110(iii)] In a gas turbine plant for jet-propulsion, having the turbine and compressor rotors supported by three bearings, one at each end of the axial-flow compressor and the third on the down-stream side of the turbine rotor, the third bearing is carried in a housing supported in the turbine stationary structure, or in the exhaust assembly, by four radial members which have radially sliding engagement with the supporting structure. A stub shaft 21 is formed on the down-stream side of the turbine disc 11a and the outer member of the bearing 20 is carried by a ring 24 of T- shaped cross-section. The ring is secured to an annular member comprising a dished disc 22 and a hollow rim 23. The rim has four flanged ports to which are secured the flared inner ends 28 of members 27. The members 27, which lie obliquely in radial planes, pass through the exhaust assembly and are slidingly supported in it by sleeves 29. Two opposite members 27 form pipes by which cooling air is led to the hollow rim 23 and the other two contain pipes 36 for leading oil to nozzles 37 which direct the oil on to the bearing. Some air from the hollow rim 23 passes through holes 33 and between the turbine disc and a cover plate 34 and escapes into the exhaust stream. Other air passes up the members 27 around the oil pipes 36, part going through holes 39 into a cavity 40 and escaping to exhaust through holes 41 and 42 and part going through holes 38 into the space 17. Ports 39 occur also in the two members 27 which lead the air inwards.
