- Figure 6' is a section on the line 66 of Figure 5
- Figure 7 is a developed view on the line 77 of Figure 5.
- a gas-turbine engine comprises a compressor 10 having an annular delivery structure, an axial-flow turbine 11 arranged coaxially with the compressor 10 and axially spaced therefrom, and annular combustion equipment 12 connected between the outlet end of the compressor 10 and the inlet side of the turbine 11 and surrounding a shaft 13 connecting the turbine rotor 11a with the compressor rotor (not shown). Fuel is burnt in the combustion equipment to heat air delivered thereto by the compressor, and the heated products of combustion pass through the turbine to drive it. I
- the annular combustion equipment 12 comprises an outer air casing member 14 which may be formed in one or more parts, and which interconnects the outlet end of the outer wall 18 of the compressor delivery annulus 10a with the inlet end of an outer shroud 15 for the inlet nozzle guide vanes 16 of the turbine 11.
- the combustion equipment 12 also comprises an inner air casing 17, which mayalso be formed in any number of parts, located coaxially with and within the outer casing 14 and connecting the inner wall 19 of the compressor delivery annulus 10a with the inner shroud 20 for thenoz'zle guide vanes 16 of the turbine 11.
- the two casings 14, 17 are thus radially spaced apart so as to afiord an annular duct for working fluid extending between the compressor delivery annulus 10a and the nozz'le-guide-vane assembly 15, 16, 20.
- the flame tube Arranged within the annular duct is a flame tube into which the fuel to be burnt in the combustion equipment is' delivered by a ring of injectors 21.
- the flame tube comprises an inner wall 22 and a coaxial outer wall 23, these walls being radially spaced apart from one another, being coaxial with the casings 14, 17 and spaced from the inner and outer casings 14, 17 so as to afford a pair of air passages 24, 25, one outside the flame tube and one inside the flame tube.
- I II I Air entering the combustion equipment partly enters the flame tube 22, 23 through a mouth afforded between the upstream edges of the walls 22, 23 to provide primary combustion air and partlyflows through the air passages 24, between the flame tube walls 22, 23 and the casings 14,..17.
- a number of holes 26 are provided in the flame tube walls 22, 23 to permit secondary combustion air to enter the flame tube to ensure an adequate supply of air to complete combustion of the fuel prior to theworking fluid leaving the combustion equipment.
- the secondary air holes 26 are in this instance located 4 at points about one-third of the length of the flame tube from its inlet end; I I I
- the downstream portions of the flame tube walls 22, 23 are shaped to afford outlets 22a, 23a from the passages 24, 25 by which streams of cooling air can be fed over the surfaces of the vanes 16 of the nozzle guide vane assembly 15, 16, 20 of the turbines 11.
- the walls 22, 23 have each a number of flutes 22b, 235 respectively forming these outlets 22a, 23a, which nu'm her (as will best be seen from Figure 2) corresponds to the number of vanes 16 in the nozzle guide vane assembly 15, 16, 20 of the turbine.
- Each flute 22b, 231) (as will best be seen from Figure 1) increases radially in depth from a point about midway of the length of the corresponding flame tube 22, 23 to the delivery end of the flame tube, and, adjacent the delivery end of the flame tube, each outlet 22a, 23ahas a depth approximately half the extent of a vane 16 of the nozzle guide vane assembly 15, 16, 20.
- the combustion products leave the flame tube through the spaces 22c, 230 between the outlet-forming flutes 22b, 23b of the flame tube walls 22, 23, which have a spacing substantially corresponding to the spacing of the vanes 16 of the nozzle guide vane assembly 15, 16, 20.
- the combustion gases flowing between the nozzle guide vanes 16 are substantially uncooled by the air flowing from the air passages 24, 25 downstream of the holes 26 so that the circumferential temperature distribution in the nozzle-guide-vane assembly is not uniform.
- each of the flame tube walls 22, 23 is formed with a number of flutes 22d, 23d forming outlets 222, 23:: equal to half the number of vanes 16 in the nozzle guide vane assembly 15, 16, 20 of the turbine 11, and each outlet 22e, or 23elfrom the air passages 25 or 24 extends axially (Figure 3) from about mid-length of the corresponding flame tube wall 22, 23 to the delivery end thereof and ( Figure 4) increases in depth from zero at the mid-length of the corresponding flame tube wall to a radial extent at the delivery end of the flame tube corresponding to the length of a vane 16 of the nozzle-gui-de-vane assembly 15, 16, 20.
- the inner and outer walls, 22, 23 of the flame tube are arranged so that ( Figure 4) the outletforming parts, or flutes, 220! on the inner wall 22 are intercalated with outlet-forming parts 230! of the outer wall 23, and thus air from the air passage 25 is employed to cool each alternate vane 16 of the nozzle-guide-vane assembly 15, 16, 2t) and air from the outermost air passage 24 is employed to cool the remainder of the vanes 16 of the nozzle-guide-vane assembly.
- the number of burners 'or fuel injectors 21 employed in the combustion equipment 12 is an integral fraction of the number of vanes 16 (and thus the number of vanes 16 is an integral multiple of the number of burners or injectors 21) and the burners or injectors 21 are preferably arranged so that the hot streaks formed in the gas flow by the combustion products tend to pass between the vanes and do not tend to impinge on them, I I
- burners or injectors may however be equal to the number of varies in the nozzle-guide-vane assembly and a construction of combustion equipment embodying this and other novel features is shown in Figures 5 to 7.
- the combustion equipment comprises an outer cylindrical air casing 30 to which is socured internally, as by Welding, curved wall pieces 31', 32 of which wall piece 31 affords the inlet end of the outer boundary of an air passage 33 and of which wall piece 32 affords the outlet end of the outer boundary of the air passage 33.
- the wall piece 32 has a cylindrical downstream extension 32a which affords the outer shroud of a ring of say 16 nozzle guide vanes 34, the leading edges of which are inclined forwards from their radially inner ends to their radially outer ends.
- the combustion equipment also includes an inner air casing 35 which is shaped at its upstream end to form the inlet end of the inner boundary or a second air passage 36 and which carries a curved wall piece 37 to form the outlet end of the inner boundary of passage 36.
- the inner casing 35 also has secured to it brackets 38 to which is bolted a ring 40 for supporting the downstream edge of wall piece 37, and to which is also bolted an internal flange 39a of an inner shroud 39 for the nozzle guide vanes 34.
- the inner ends of the vanes 34 are provided with tablets 34a which are Welded to the shroud 39.
- the combustion equipment also comprises a flame tube having an outer wall 41 affording the inner boundary of the air passage.33 and an inner wall 42 affording the outer boundary of the inner air passage 36.
- the upstream edges of the walls are turned over and in the annular gap left between the edges, there are mounted a number of frusto-conical tubes 43, the number being equal to the number of vanes 34 and as will be seen from Figure 6, the tubes 43 are staggered circumferentially with respect to the vanes so as to appear, when the combustion equipment is viewed axially, to be each symmetrically between a pair of vanes 34.
- the tubes 43 are connected to the upstream edges of the walls 41, 42 and each supports within it a spider 44, the hub 44a of which is a frusto-conical shroud for a fuel injector 45.
- the downstream ends of the walls 41, 42 are formed to provide air outlets from the passages 33, 36 respectively, to deliver cooling air to flow over the nozzle guide vanes 34.
- Each wall 41, 42 has a number of slots 46 cut in it from its downstream edge and outlet chutes 47 are fitted in the slots and secured in position on the walls by flanges 47a thereon being welded to the wall.
- the chutes 47 increase in radial depth in the direction of flow, and the chutes 47 at their downstream ends lie close to the upstream edges of the vanes 34 and have a combined depth equal to the radial extent of the vanes 34.
- the flame tube is supported at its upstream end by brackets 48 connecting the wall 42 with the inner casing 35 and at its downstream end by dimples 49 formed in the flanges 47a engaging the wall pieces 32 and 37 respectively.
- nozzle-guide-vane cooling arrangements described may also be employed with advantage in multi-stage turbines, it having been found that the non-uniform circumferential temperature distribution created by delivering cooling air from the air passages through the cooling air outlets tends to persist beyond the first-stage rotor blading, so that overheating of the second-stage nozzle-guidevane assembly of a multi-stage turbine may be avoided by suitably selecting its angular position relative to the first-stage nozzle-guide-vane assembly so that the vanes lie in the path of the cooler air delivered over the vanes of the first-stage nozzle-guide-vane assembly.
- a gas-turbine engine comprising annular combustion equipment which includes inner and outer annular casings and inner and outer annular flame tube walls, said flame tube walls being spaced radially to afford an annular combustion space and being radially spaced from the annular casings to afford annular air passages inside and outside said annular combustion space, and a turbine which is connected to receive hot gas from the combustion equipment and which has at its inlet a nozzle-guidevane assembly comprising a plurality of nozzle-guide vanes, each of said flame tube walls terminating at its downstream end close to the upstream edges of the nozzle-guide vanes and being provided with a plurality of flutes which extend from the wall into said combustion space and increase in depth towards the downstream end of the flame tube wall and terminate at said downstream end, there being one such flute aligned with each nozzleguide vane, the flutes on one of the flame tube walls being aligned with alternate nozzle-guide vanes and the flutes on the other flame tube wall being aligned with the remainder of the nozzle-guide vanes,
