Definitions
- the invention relates to turbomachines, such as those used for propulsion of aircraft, and in particular the support bracket the ring of the high pressure turbine and its mounting with minimized clearances.
- the turbine casing 1 of the stator includes annular parts 2 which face to the blades 3 of the rotor 8, at the entry of the high pressure turbine, downstream of the combustion 5. These annular parts 2 of the casing turbine 1 therefore define a clearance with the top of the blades 3 of rotor 4, consequently conditioning the efficiency of the turbomachine.
- these annular parts 2 are supplied with gas at temperatures which allow, either expand them or contract them to reduce the clearance between these to a minimum blades 3 and these annular parts 2, for the purpose thus increasing the efficiency of the turbomachine.
- the gas is usually drawn from another part of the turbomachine, depending on the gas temperature or rotor speed.
- FIG. 2 shows in detail a realization of the prior art of fixing a stator ring 2 around the ends of the blades 3 of the rotor 4.
- a ring is made up of a multitude of ring sectors 2 each positioned in support spacer sectors 4 which are fixed themselves inside the high turbine housing pressure 1.
- each spacer sector of support 4 has an upstream external foot 6M and a foot outdoor downstream 6V intended to be inserted each respectively in a 7M upstream hook or a hook 7V downstream of the high pressure turbine housing 1.
- the temperature differences for such a turbomachine, at the level of these elements, between rest and operation are considerable. It follows various dilations in three dimensions and on different scales concerning the parts constituting such an assembly. Well heard, if the game J remains in a consistent way, especially in the operating phases of the turbomachine, its efficiency will be very diminished.
- Figure 3 illustrates the establishment of a support spacer 4 having two ends 4A and 4B and a middle part 4C, represented so superimposed on part of the high turbine casing pressure 1 and its upstream hooks 7M and downstream 7V.
- the high pressure turbine housing 1 has a first radius R1 and a first width X1.
- the area support spacer 4 has a second radius R2 and a second width X2.
- the second radius R2 is off-center with respect to the first radius R1, such so that the second radius R2 is larger than the first radius R1.
- the first width X1 is, preferably larger than the second width X2.
- the support spacer sector 4 is introduced in force in the slot formed by the hooks 7M and 7V and the high pressure turbine housing 1. This assembly in force creates a spring effect in the sector support spacer 4, due to deformation or the bending of the ends 4A and 4B of this sector support spacer 4, as shown in figure 4.
- the object of the invention is therefore to propose another solution to make up for the games between the top of rotor blades and ring sectors at high pressure turbine level, trying avoid deformations due to gradients radial thermal.
- each sector support spacer has a tab longitudinal upstream, fixed upstream and on the side exterior of the upstream radial wall, having one face external support at its upstream end, projecting outwards, so as to be supported on the inner face of the high pressure turbine housing of the and to exert a thrust on it when the support spacer sector is in square.
- the bearing faces from the upstream end of the tongue are not continuous, but are separated by a recess.
- the stall when using the notch radial for the indexing pin, the stall is shallower than the length protruding from the counter of indexing to constitute a means of polarization angular during assembly of the assembly.
- Figure 5 therefore shows in section the main achievement of the spacer sector of support 14, according to the invention, fixed to the wall internal 1I of the high pressure turbine housing 1.
- This fixing is done by an external upstream hook 16M fitting into an external upstream slot 17M of the housing of high pressure turbine 1 and by a downstream hook external 16V fitting into an external downstream notch 17V of the high pressure turbine housing 1.
- This sector support spacer 14 is used to hold in place a ring sector 12 opposite the top of the blades 3 of the rotor.
- This fixing is carried out in a manner analogous to using an internal upstream hook 18M fitting into a corresponding internal upstream notch 19M in the sector of rings 12 and by internal downstream hook 18V fitting in a clamp 20 'surrounding this same downstream hook internal 18V and an internal downstream hook 19V in the sector ring 12.
- This type of closure ensures sealing at the ring sector 12.
- the spacer sector of support 14 has a tongue 20, fixed on the external part of the upstream wall 14M and extending concentrically to the spacer formed by all support spacer sectors 14, i.e. at high pressure turbine housing 1.
- This tab 20 has an end 21 which extends towards the outside so that a radial bearing surface 22 comes into contact with the internal face 1I of the housing high pressure turbine 1.
- the positions suggested by the broken lines show the natural position at cold, both from high pressure turbine housing 1 and tongue 20.
- the strong lines represent the operating position, i.e. hot where the constraints are such that deformations take place.
- Figure 5 by means of arrows, shows also the various efforts put into play at this level.
- the different arrows whose foot is on a part, represent the forces applied to these last, in particular by gases in operation normal of the turbomachine.
- the bending generated does not take place in a radial plane, i.e. perpendicular to the axis of the engine, but in a longitudinal plane. In operation, this longitudinal bending is relieved because the bearing faces are surfaces functional.
- the high turbine housing pressure 1 expands more than the pilot rings of housing 5 which are cooled by the housings impact. This differential expansion therefore relieves bending the tongue 20.
- each sector support spacer 14 can be positioned or angularly offset before being in close contact with the different parts of the housing 1.
- the outer part of the upstream wall 14M has also 24M recesses for the passage of gases, as well as the external part of the downstream wall 14V which also has 24V recesses similar to 24M recesses in the upstream wall.
- the external part of the downstream wall 14V which also has 24V recesses similar to 24M recesses in the upstream wall.
- the function of the positioning notch 25 is now explained by considering FIG. 7. Indeed, on this one, was represented a pawn anti-rotation 27 mounted tight in a hole 28 in the housing 1. Its role is to contribute to positioning angle of a support spacer sector 14 in ne allowing it to be inserted into the notches 17M and 17V of casing 1 only if the notch of positioning 25 is in front of the counter anti-rotation 27. Indeed, the length of the part protruding from this anti-rotation pin 27 is greater than the depth of the recesses 23 between the surfaces radial support 22 of the end 21 of the tongue 20. In this way, only such a unique positioning allows mounting the spacer sectors in position 14. The centering pin 27 is supported to prevent it from escapes to the outside of the assembly.
- each sector support spacer 14 for mounting, there is no need to arch or prepare each sector support spacer 14 before inserting it into the fastening elements of the high turbine casing pressure 1. In addition, it is possible to angular positioning without each sector support spacer 14 is tight.
- each sector support spacer 14 which are supported are functional surfaces, namely the bearing surfaces radial 22 of the tongue 20, and the surfaces internal 16M and 16V external hooks.
- the high turbine housing part pressure 1 located opposite the tongue 20 expands more than the latter, in operation, the pressure on the end 21 of the tongue 20, exerted by the wall of the housing of the high pressure turbine 1, is lessened and the tongue 20 is slightly relieved in pressure.
- gas efforts from engine operation help to ensure the positioning of all spacer sectors support 14.
- each support spacer sector 14 pressing against the internal wall 1I of the high pressure turbine casing 1, helps position other surfaces of each spacer sector of support 14 against the fixing elements of the housing high pressure turbine 1. In other words, there is a intimate contact, especially at the hooks 16M and 16V upstream external devices with the elements are opposite.
- the tongue 20 tends to position each support spacer sector 14 furthest away from the high turbine housing pressure 1, thus reducing the clearance J remaining between the apex of each blade 3 and the ring sectors 12 fixed to the support spacer sectors 14.
