Definitions
- This talk deals with a set of ventilation of a stator ring, intended to convey a gas at a determined temperature up to a ring turbomachine stator to adjust its diameter and the game he will do with blade tips of rotor rotating in it.
- Such ventilation assemblies are commonly used in turbojets and consist of multi-branched conduits taken up and the ends of which are provided with holes to blow gas and especially air to a large number of points, judiciously distributed, of the ring.
- Terminal conduits are very often ramps running around the rings, in the shape of an arc of a circle and embracing part of their perimeter. Often too, the gas is blown in the axial direction, on outer ribs of the ring rather than on the ring itself, so that the diameter is controlled by these ribs which are more rigid and govern therefore the deformations of the ring proper.
- the assembly which will be described here is characterized in that it is easy to manufacture, despite the large number of conduits that are generally required use, and assemble to the ring despite the complications which can arise from dilations differential thermal at different times of machine operation.
- the invention thus relates to a ventilation assembly of a ring stator composed of branched conduits comprising supply lines, distributors and ramps adjacent to the ring and provided with holes blowing of gases directed towards the ring, characterized in what the ramps are made up of pairs of half shells including a flange and a border surrounding the flange, the pairs of half-shells being joined by the edges, the distributors include spool coils between the ramps and fitted with end edges shaped to fit on side cheek openings of the flanges.
- a stator ring 1 is associated with a group of ventilation units 2 conforming to the invention, each of which occupies a portion of the circumference of ring 1 and includes a group of ramps 3 parallel and in an arc, distributor 4 for distributing air from ventilation between all ramps 3 and a duct supply 5 (visible in Figure 2) connected to the distributor 4.
- supply lines 5 join after one or more others distributors, which are not shown because they are not the subject of this invention; this one relates more specifically to the end of the assemblies ventilation 2, i.e. their parts which are close to ring 1 to be ventilated.
- each of the ramps 3 is composed of a half-shell left 7 and a right half shell 8 of which each of these is assembled to one of these. More precisely, the half-shells 7 and 8 of the two genera each include a flange 9 substantially flat and a border 10 established around the flange 9, the borders 10 of pairs of half-shells 7 and 8 additional being extended and joined to form a single ramp.
- Half-shells 7 and 8 can be made by simple operation stamping and the connections between the borders 10 can be performed by welding. This mode of manufacturing is extremely simple and avoids having to machine tubes to bring them to shapes and desired dimensions, which would probably be a lot more tedious.
- half-shells of left 7 can generally be built at from the same tool as the right half-shells 8 which are symmetrical to the previous ones by the plane of seal.
- This overall similarity does not exclude some dissimilarities of details.
- half-shells 7 and 8 could be constructed with borders 10 of different widths, so for example favor ventilation by the 3 most wide.
- An example of application of this process appears in Figure 2, where three ramps 3 ventilate two ribs 11, the central ramp being placed between the two ribs 11 and ventilating them both, which justifies that its width is double.
- the distributor 4 also includes coils 15 in the form of a short cylinder serving spacers between the ramps 3 and with the conduit 5. It is often beneficial that they are similar, but they can also be different in particular in length. They understand generally edges 16 to be engaged in the openings 13 ramps 3 to hold them in place, and flanges 17 pressing on the ramps 3 to define the spacing of these. Distributor 4 is formed when the coils 15 have been soldered to ramps 3. However, the distribution duct 5 remains generally separate from dispenser 4 and can slide in the input coil 15, a seal sealing 18 being added between them, however.
- one of the coils 15 comprises planar faces and opposite 19 enclosing the end 20 (here enlarged) of the rib 11 which the corresponding coil 15 overcomes.
- the reduction in the axial clearance between the coil 15 and the enlarged portion of the rib 11 contributes to ensuring the axial positioning of the distributors 4 on the ring 1.
- the second coil overlaps its ring with axial play, this to allow the relative dilations between the housings 4 and casing 1 without generating a connection hyperstatic and unwanted constraints.
- FIG. 3 shows that the end 20 of this rib 11 has a v-notch 21 in which the central, cylindrical portion of the coil 15 rests in self-centering, which guarantees the distributor 4 against radial movements and tangents to ring 1: perfect positioning radial, tangential and in orientation along the axis of the engine is performed.
- Brackets 22 are linked to one end of the stator ring 1 by fixing bolts 23 and include a wing 24 under one end of the ruler 6; the other end of it is placed on a boss 25 of the stator ring 1.
- Bolts 26 and 27 are screwed to wing 24 and boss 25. They maintain the ends of rule 6 on them by compressing springs 28 based on rule 6 by washers 29.
- Such an assembly has the property of allow better control of the support effort of rules 6 on equettes 24 and 25. If this effect is excessive, the assembly is rigid and does not allow thermal respiration.
- rule 6 to which ramps 3 are welded, is provided with 30 wide openings around bolts 26 and 27, so that it can be move by sliding axially and tangentially by compared to the stator ring. This flexible mounting avoids therefore to produce excessive internal stresses in ventilation assembly 2, since the ramps 3 have the ability to move above the ring 1 without exerting too much effort. These relative displacements are generally due to thermal expansions differential.
- the support of one of the coils 15 against the end 20 of the corresponding rib 11 offers also some flexibility by allowing all of ventilation 2 to move to the ends, while being recalled towards the stator ring 1 and the bottom of the vé 21 by springs 28. This flexibility is valuable by absorbing expansions inevitable differential thermal with such equipment.
