Definitions
- the present invention relates so general to a ring sector turbomachine cooled.
- the invention relates to a turbomachine comprising a casing, a rotor and that a plurality of cooled ring sectors interposed between the casing and the rotor, each of these ring sectors being provided with at least one cavity of cooling.
- Ring areas can indifferently to be turbine ring sectors, preferably a high pressure turbine, or compressor ring areas.
- the invention finds an application not exclusive but more specific when relates to a turbine of the turbomachine, in the since the significant thermal stresses surrounding require the presence of such areas ring cooled.
- FIG. 1 it is partially shown a portion of high turbine pressure of a turbomachine 1 of the prior art, such than that described in document FR-A-2 800 797.
- the high pressure turbine comprises a turbine casing 2, as well as a rotor 4, of which only one end of the blades 6 is shown.
- the turbine is provided with a plurality of cooled ring sectors 8 mounted on the turbine casing 2, and forming a ring around the blades 6 of the rotor 4.
- the latter comprises all first, on the upstream side, a hook 10 intended to cooperate with a hook 12 belonging to the sector ring 8. So, once hooks 10 and 12 are nested, they allow the pivoting of the sector ring 8 until it comes up against downstream against the turbine casing 2, by bringing the ledges 14 and 16.
- Tightening in axial direction of the sector ring 8 on the casing 2 is then provided by a tenon 18 secured to a downstream part of this sector, the tenon 18 being located upstream relative to the flange 14 of the ring sector 8, and being located on the side of a inner chamber 20 partially delimited by the turbine housing 2.
- the tenon 18 is retained by a mortise 22, formed by through the edge 16 of the casing, as well as by an elastic tab 24 which once allows mounting performed, to remove the axial play of the lug 18.
- each ring sector 8 is carried out using a staple 26, the branches of which serve to grip the edges 14 and 16, these being respectively provided with notches opposite 28 and 30 between which can be slid the core of clip 26, pushing it upstream.
- the mounting system of the ring sectors on the housing is very design complex, and therefore generates relatively low costs important.
- the inner chamber 20 is supplied with cooling air via one or more cooling orifices 27 practiced through in the casing 2, this cooling air being for example taken from the level of one of the compressors (not shown) of the turbomachine 1.
- this one After the introduction of air from cooling in the inner chamber 20, this one passes through a perforated wall 23 of the ring sector 8 in order to enter a cooling cavity 25 provided in the latter.
- the invention therefore aims to provide a turbomachine comprising a casing, a rotor and that a plurality of cooled ring sectors interposed between the casing and the rotor, the turbomachine at least partially remedying the disadvantages mentioned above relating to the achievements of art prior.
- the invention relates to a turbomachine comprising a casing, a rotor and that a plurality of cooled ring sectors interposed between the housing and the rotor, each sector ring including a cooling cavity main and being mounted on the turbine housing by by means of fixing means.
- the fixing means comprise a screw clamping position substantially radially and ensuring the plating of the ring sector against the casing, this clamping screw being traversed by a cooling air passage communicating with the main cooling cavity of the sector ring.
- the fixing means have a design greatly simplified compared to that means presented previously, insofar as they no longer require hooks or staples extremely precise dimensions, but on the contrary are essentially consisting of a simple clamping screw.
- the clamping screw arranged radially provides axial positioning and very precise tangential of the ring sector compared to the turbine housing, thus considerably limiting cooling air leaks between these elements. In this way, the turbine housing is better protected thermally, and the ring sectors can be completely satisfactorily cooled.
- the fixing means used in the invention provide simplicity of assembly as well as a reduced cost compared to those of art described above and shown on the figure 1.
- the fact of providing one or multiple air passages through the screw allows advantageously to combine the fixing means of each ring sector with the means necessary to the supply of cooling air to the cooling cavity of the ring concerned.
- the cooling air collected at the desired location such as for example at level of a turbomachine compressor, penetrates in an outer radial end of the air passage, then crosses it until it is ejected by a internal radial end, to then integrate the main cooling cavity and thereby ensure the cooling of the ring sector.
- the clamping screw is crossed longitudinally by a single air passage of cooling, which therefore leads in particular to the level of the screw head.
- the fixing means comprise a spacer mounted on the housing and crossed by the screw tightening, the spacer ensuring positioning axial and tangential of the ring sector with respect to the casing, as well as the desired pretension.
- the spacer has an inside diameter substantially equal to an outside diameter of at least a portion of the clamping screw lying opposite of the spacer, and / or that the spacer has a lower end inserted in a bore provided on the ring area, this lower end having an outer diameter substantially equal to an internal diameter of the bore.
- the spacer constitutes a stop for this ring sector, so as to ensure the radial positioning of the latter relative to the casing. So with such a configuration, a simple judiciously arranged spacer on the housing allows to achieve a very precise positioning of the sector ring relative to this housing, as well axially, tangentially than radially.
- each sector ring has a threaded portion cooperating with the clamping screw, the head of this clamping screw being abutted against an upper end of the spacer.
- another solution ensuring the plating of the ring sector against the housing could be to provide that each ring sector has a footprint the interior of which is housed in abutment the head of the clamping screw, the latter cooperating with a nut in abutment against an upper end of the spacer passing through the casing.
- each ring sector can have an upstream end as well as an end downstream, the upstream end being in contact with a upstream circular flange belonging to the casing, and the downstream end being in contact with a flange downstream circular belonging to this same casing.
- each ring sector further comprises a cavity of separate secondary cooling of the cavity main cooling by a wall, these cavities main and secondary being superimposed radially.
- a turbomachine is partially shown 100, according to a first preferred embodiment of the present invention.
- the turbomachine 100 comprises a casing 102 as well as a rotor 4 provided with blades 6.
- the invention finding a very particular application when applied to a turbine of the turbomachine 100, we will consider in the following the description that the part shown in Figures 2 and 3 corresponds to a high pressure turbine of this turbomachine, and that consequently, the casings 102 and rotor 4 correspond respectively to a housing of turbine 102 and to a turbine rotor 4 provided with blades 6. It is noted that this choice of application of the invention to a turbine, preferably to the turbine high pressure subject to heavy loads will be adopted for all modes of preferred embodiments shown in FIGS. 2 to 6, and described below.
- the turbine includes a plurality of cooled ring sectors 108 mounted on the turbine casing 102 by means fixing 132, the ring sectors 108 forming a ring around the blades 6 of the turbine rotor 4.
- the fixing means 132 have a clamping screw 134 positioned substantially radially with respect to the housing turbine 102.
- the clamping screw 134 is arranged so that its longitudinal axis (not shown) is substantially parallel to a radial direction of the turbomachine 100.
- the fixing means 132 include a spacer 136, integrally mounted or with a calibrated clearance on the casing 102 which it crosses, this spacer 136 also called “sleeve of guide ”being traversed by the clamping screw 134 and therefore also having a longitudinal axis positioned substantially radially.
- the clamping screw 134 has a portion 138, located under the head 140 and opposite the spacer 136, the outside diameter of which is substantially equal to the inside diameter of this same spacer 136.
- the clearance between the screw 134 and the spacer 136 being almost zero, the clamping screw 134 is then positioned axially and tangentially very precisely with respect to the turbine casing 102, insofar as it is joined together to the spacer 136, for example by welding, or even mounted with almost zero play.
- the ring sector 108 has a threaded portion 141 cooperating with the threaded portion 142 of the fixing screw 134. From this way when the ring sector 108 cooperates with the fixing screw 134, it is also positioned axially and tangentially very precisely relative to the turbine casing 102.
- the spacer 136 has a lower end 136a inserted inside a bore 144 provided on the ring sector 108, the outside diameter of the lower end 136a being substantially equal to the internal diameter of bore 144. With such a layout, it is no longer necessary to plan the identity between the inner diameter of the spacer 136 and the outside diameter of the portion 138 of the clamping screw 134.
- the head 140 of the screw 134 located radially outwardly relative to the portion threaded 142, abuts against one end upper 136b of the spacer 136.
- An anti-rotation plate 146 can optionally be inserted between this upper end 136b and the head 140 of the screw 134, so that it can no longer loosen once assembled.
- the lower end 136a of the spacer 136 can also be a stop for the ring sector 108, so as to ensure a very radial positioning precise of the latter with respect to the turbine casing 102, or even a controlled prestress.
- the spacer 136 is sized so that when the ring sector 108 abuts against its lower end 136a, the bosses 148 and 150 from this same sector come simultaneously abut against the casing 102.
- the turbine is designed so that the ring sector 108 has an upstream end or upstream edge in contact with an upstream circular flange 152 belonging to the turbine casing 102, as well as a downstream end or downstream edge in contact with a circular flange downstream 154 belonging to this same casing.
- the contacts established by the flanges 152 and 154 with sector 108 are preferably plan contacts, belonging to plans substantially perpendicular to a main longitudinal axis (not shown) of the turbomachine 100.
- ring sectors 108 are connected to each other through tabs seal 156, limiting gas flow in the axial and radial directions.
- each ring sector 108 has an upper wall 158 and a lower wall 160 radially superimposed and defining a cavity main cooling 162, these two walls being indifferently carried out separately then assembled together, or made in one piece.
- each ring sector 108 includes no other cooling cavity than the main cavity 162.
- the clamping screw 134 is provided with one or more air through passages cooling 174, preferably only one, which is practiced so as to communicate with this same main cavity 162. Indeed, air from cooling can be taken for example at the level of a turbomachine compressor 100 and then be routed to an outer radial end (not referenced) from passage 174, this outer end being located radially outwardly relative to the turbine casing 102.
- the passage of air from cooling 174 is centered on the axis of the screw clamping 134, and has a cylindrical shape of circular section. Furthermore, it is noted that for obtain the desired air flow, it is possible to directly calibrate passage 174, or place calibrated washers (or pads) at the interior of these passages 174. Naturally, the interest of this last solution lies in the fact that when you want to change the air flow of cooling passing through the passages 174 it it is only necessary to change the washers (not shown). On the other hand, this platelet solution also provides different air flows depending on the floors of the turbine, while using the same drilled screws dimensions.
- the upper wall 158 participates in delimiting the interior chamber 120, inside which air can also be introduced cooling. So the cooling air penetrating inside the chamber 120 can also join the cooling cavity 162 in using through orifices (not shown) made in the upper wall 158, so as to allow ring sectors 108 to cool by direct impact on the cavity wall. In such case, it is to be understood that the cavity of cooling 162 is then supplied with air by two flows, taken for example respectively from the high pressure compressor and at compressor level low pressure of the turbomachine 100.
- the ring sector 108 has a wall upper 164 defining a cavity of main cooling 166 with a wall intermediate 168, also called “impact sheet”.
- sector 108 has a lower wall 170 defining a cooling cavity secondary 172 using the intermediate wall 168.
- the two cavities 166 and 172 are superimposed radially, the main cavity 166 being for example smaller than the secondary cavity 172.
- cooling air ejected from the internal radial end of passage 174 enters the main cavity 166 in a way identical to that shown above and then is likely to join the secondary cavity 172 in using through orifices (not shown) made in the intermediate wall 168. From this way, it is possible to achieve cooling ring sectors 108 by impact or convection.
- the air of cooling located in the interior chamber 120 is able to penetrate inside the cavity 166 through through holes (not shown) made in the upper wall 164.
- the wall upper 164 has the threaded portion 141 necessary for fixing the ring sector 108 on the clamping screw 134, this threaded portion 141 opening into the main cavity 166.
- FIG. 6 it is partially shown a turbomachine, according to a second preferred embodiment of this invention.
- turbomachine 200 according to the second embodiment preferred of the present invention is widely similar to the turbomachine 100 according to the first mode preferred embodiment.
- the main difference is in the fixing means 232 of the cooled ring sectors 208 on the turbine casing 102. Indeed, if the spacer 136 is similar to that presented in the first preferred embodiment, it is not the same for the clamping screw 234.
- This screw tightening 234 actually includes a head 240 capable of be precisely stuck in a cavity 276 belonging to an upper sector ring 208, this borrows 276 defining a space 280 with an upper wall 258 of the ring sector 208, located radially inside with respect to borrows 276.
- the clamping screw 234 has a threaded portion 242 projecting from spacer 136 outward, and cooperating with a nut 278 positioned in abutment against the upper end 136b of the spacer 136, the nut 278 therefore being located radially outwardly relative to the casing 102. Therefore, tightening the nut 278 causes a outward radial movement of the ring sector 208, until it comes into contact with the housing turbine 102. As can be seen in FIG. 6, the contact takes place at the level of the upstream boss 148 and downstream boss 150 provided on the upper part of the ring sector 208. Furthermore, as indicated previously, the movement in the radial direction of the ring sector 208 could be stopped simultaneously by the latter coming into contact with the end lower 136a of the spacer 136.
- each sector ring 208 has the upper wall 258 and a lower wall 260 being radially superimposed, these walls 258 and 260 defining therebetween a main cooling cavity 262, and being indifferently carried out separately then assembled together, or made in one piece.
- the tightening screw 234 is provided with one or more air through passages cooling 274, preferably only one, which is practiced so as to communicate with this same main cavity 262.
- air from cooling can be taken for example at the level of a turbomachine compressor 200 and then be routed to an outer radial end (not referenced) from passage 274, this outer end being located radially outwardly relative to the turbine casing 102.
- an internal radial end (not referenced) from passage 274 is in communication with this same space 280, which is itself in communication with the cavity 262 via one or more through holes 282 made in the upper wall 258.
- the cooling air passage 274 is in communication with the main cavity 262, from so that air ejected from the inner radial end can then penetrate inside this cavity 262, and cool the ring sector 208.
- the cooling air path described above is shown schematically on the Figure 6, by arrow 275.
- the passage of air from cooling 274 is centered on the axis of the screw tightening 234, and also has a cylindrical shape of circular section.
- the clamping screws 234, the different sectors of 208 rings and tabs 156 are installed before assembly spacers 136 on the casing 102, so that that the ring sectors 208 each have a degree of tangential freedom for mounting tabs 156.
- the spacers 136 are mounted on the turbine casing 102 so as to be crossed by the clamping screws 234.
- the ring sectors 208 having been set up so offset from their final position can then be rotated until the heads 240 enter the respective imprints 276.
- turbomachines 100 and 200 which have just been described, only by way of nonlimiting examples.
