Title: Fluid cooled porous stator structure
IPC: F01D11/12
Filed: 1967-07-31
Abstract: 1308771 Turbine blade shrouds GENERAL ELECTRIC CO 31 July 1967 [2 Nov 1966] 35001/67 Heading F1T A gas turbine comprises circumferentially spaced-apart turbine blades mounted for rotation about an axis and extending radially of the axis across an annular passageway for the flow of high temperature motive fluid, with an annular, porous shroud circumferentially surrounding the outer tips of the blades in closely spaced relation thereto so as to control leakage of the motive fluid around the tips, and means for supplying cooling fluid to at least a portion of the outer surface of the shroud, the shroud comprising a material having randomly disposed and inter-connected interstices forming minute passages inter-connecting its outer and inner surfaces. The shroud may consist of randomly disposed wires or woven wires sintered or brazed to form a composite structure having a certain degree of porosity. As shown in Fig. 2, the shroud 20 is a relatively thin annular ring closely surrounding the outer tips 42 of the turbine blades 23. A support member 50 includes annular support flanges 53, 54 which engage mating flanges 55, 56 projecting inwardly from an annular bracket 57 supported by the turbine casing 11. Circumferential ridges 58 project inwardly from the support member 50 to engage the outer surface 46 of the shroud 20. At least the extreme upstream and downstream and preferably all of the ridges 58 are secured to the shroud 20 as by welding or brazing. Annular regions 62a, b, c thus formed between the shroud 20 and the support member 50 are connected to a plenum 52 by openings 63a, b, c in the member 50. Relatively low temperature air is supplied through springs 65 in the bracket 57 to the plenum 52. The shroud 20 is permeated and thereby cooled by the air. In a modified construction, an annular band of abradable material such as open celled metallic honeycomb material is secured to the inner surface of the shroud. Rubbing can thus occur between the blade tips and the annular band without any effect on the permeability of the shroud, and a significantly smaller operating clearance can therefore be tolerated.

The hammer is raised by depressing a treadle y which operates a rod x<11>, lever z, and rod d<11> to rotate a valve e admitting air to cylinder f, whereby piston g is moved against the pressure of a spring h so that levers k are actuated to press the chains n against the hammer lift-rod. Treadle y operates another rod x<1> and valve w of a cylinder u which actuates rods H and eccentric levers v carrying tupsustaining blocks t adapted to hold the lift-rod r stationary prior to its descent. At the top of its stroke the tup b actuates a lever d and operates the valve e so as to exhaust the cylinder f, releasing the pressure of the chains on the lift-rod ; at the same time the valve w is operated by the action of the members x<11>, y, x<1> whereby the cylinder u is exhausted and the sustaining blocks t released from the lift-rod. The force of the blow is increased by the action of a piston B at the top of the lift-rod working in a cylinder A. The rod is connected to the tup by a friction device r<1>.

Class 56 In a drawing of continuous glass fibres the strand is engaged by a single moving surface and successive parts of the strand along its length are caused to adhere momentarily to the moving surface whereby drawing tension is applied. Several forms are described. In Fig. 1, for example the strand 24 is wetted at the gathering shoe 23 and thereby caused to adhere to the wheel 27 until it is blown therefrom by an air-jet 29. In Fig. 5 the strand 33 is guided on to the wheel 34 by an arcuate shoe 35 and after traversing most of the periphery of the wheel is removed by the piling up of entrained air in front of a deflector 36. In Fig. 11 the wheel 41 is provided with tapering notches 42 and the strand 44 can be guided by a shoe 45 and carriage 46 so as to engage the whole surface of the wheel or less thereof as the carriage is moved towards the left thereby varying the drawing tension on the strand. In Fig. 14 the periphery of the wheel 49 is provided with non-wettable insets 53 so that the strand 51 tends to cling tightly to the wettable areas 52 and to leave the wheel at a non-wettable portion 53. In Fig. 18 the non-wettable insets 53 are replaced by notches 58.
