Title: Improvements in or relating to turbines
Inventor: HAWORTH LIONEL
IPC: F01D17/16
Filed: 1955-08-16
Abstract: 802,165. Elastic fluid turbines. ROLLS-ROYCE, Ltd. Aug. 16, 1956 [Aug. 16, 1955], No. 23639/55. Class 110 (3). An elastic-fluid turbine comprises nozzle guide vanes having a variable throat area, the vanes having shrouds at their inner and outer ends and each shroud having a radially inner part and a radially outer part, the part further from the vane portion being fixed and the part adjacent the vane portion being accommodated in a recess in the other part and shaped to have a recess adjacent the trailing edge of the vane which abuts against and is pivotable about a substantially radial axis on a corresponding part of the wall of the recess. In the gas turbine engine shown in Fig. 1, the turbine nozzle guide blading comprises a fixed outer shroud part 19 in the form of a complete ring or, say, four segments. The shroud part 19 has flanges 20, 21 which engage grooves in flanges 22, 23 formed on the casing wall, and dogs 24, 25 which engage slots in the flanges 22, 23. The shroud part 19 also abuts an annular shroud ring 26 having lugs 27 which engage bayonet fashion in slots in the flange 23. A fixed inner shroud part 29 for the nozzle blading is located in a similar manner by a flange 30 and dogs 32 which engage a flange 31 carried by an inner wall 15, and is also bolted to the wall 15 at 33. The shroud part 19 may alternatively be mounted as described in Specification 790,854. Each guide blade comprises outer and inner movable shroud parts 37, 38 integral with a blade part 36 and accommodated in recesses 34, 35, Figs. 1 and 3, in the fixed shroud parts 19, 29. The guide blades are pivotable about pivots formed bv engagement of the rounded downstream ends 42 of the shroud parts 37, 38 with correspondingly rounded ends of the recesses 34, 35. They can be moved by pistons 53a, 53b from the position shown in Fig. 3, in which the area of the throats 48 is a minimum, to a position in which the straight sides 39 of the movable shroud parts 37, 38 abut the straight faces 46 of the recesses 34, 35. For this purpose, the interiors of the cylinders 54a, 54b are connected through ducts 58a, 58b with manifolds 59a, 59b respectively. The manifolds are interconnected by ducts 63, 65, Figs. 1 and 2, and when a valve 68 is in the position shown, they are exposed to the air pressure within the space 56 surrounding the flame tube outlet duct 9, a leak through a small bleed hole 73 reducing this pressure slightly so that the pressure communicated to the interiors of the cylinders 54a, 54b is slightly less than the external pressure. This pressure differential is sufficient to take up the backlash between the piston-rods and the shroud parts 37, 38, but insufficient to move the guide blades from the position shown, in which the blades are held by the gas load acting on them. When the valve 68 is moved to its other position, the interior of the cylinders 54a, 54b is vented to atmosphere through a port 72, and the pressure in the space 56 acts on the pistons 53a, 53b to move the guide blades to their alternative position.
