Abstract

895,075. Gas turbine plant. ROLLS-ROYCE Ltd. Nov. 18, 1960 [Nov. 26, 1959], No. 40278/59. Class 110 (3). A turbine driven fan unit 14 comprises a fan turbine casing 12 mounted at the upstream end of the unit and directly connected to the rear of a gas turbine engine 10, a fan outer casing 13 surrounding the fan turbine casing 12 forming an annular space 15, rotor means having turbine and fan blading with the fan blading 17 in the annular space 15, and bearing means solely supporting the rotor, the bearing means being solely and directly supported from the fan turbine casing. Inverted V-shaped struts 16 support the fan outer casing 13. The fan rotor blades 17 are integral with the second stage blades 18 of the fan turbine 11, the first and second blade rows thereof being carried by a common rotor disc 20 at the downstream end of a shaft 21. The shaft 21 is journalled by bearings 22, 23 within a sleeve 24 which is supported from the casing 12 by faired struts 25. A tube 27 is spaced concentrically from the shaft 21 by annular discs 28, 29. The tube 27 receives lubricating oil which passes through drillings 30, 31 in the discs 28, 29 respectively, to the bearings 22, 23, and so to an annular space 32. Tubes 33 scavenge a mixture of oil and air from the space 32 to a manifold 34 which is arranged to dump the mixture overboard clear of the intake of the fan unit 14. The invention is also applicable to a vertically mounted fan unit on a vertical gas turbine engine.
