- FIG. 1 illustrates in its environment a combustion chamber 10 for a turbomachine.
- a turbomachine comprises in particular a compression section (not shown) in which air is compressed before being injected into a chamber housing 12, then into the combustion chamber 10 mounted inside thereof.
- the compressed air is introduced via air inlets into the combustion chamber and mixed with fuel prior to being burned.
- the gases resulting from this combustion are then directed to a high-pressure turbine 14 disposed at the outlet of the combustion chamber.
- the combustion chamber is of the annular type. It is formed of an inner annular wall 16 and an outer annular wall 18 which are joined upstream by a transverse wall 20 forming the chamber bottom. It can be direct as illustrated or reverse flow. In this case, a return elbow is placed between the combustion chamber and the turbine distributor.
- the inner annular walls 16 and outer 18 extend along a longitudinal axis slightly inclined relative to the longitudinal axis 22 of the turbomachine.
- the chamber bottom 20 is provided with a plurality of openings 20A in which are mounted the same plurality of fuel injectors 24.
- the chamber cover 12 which is formed of an inner envelope
- the inner annular walls 16 and outer 18 each have a cold side 16a, 18a disposed on the side of the annular space 26 in which the compressed air circulates and a hot side 16b, 18b turned towards the inside of the combustion chamber ( see Figure 4).
- the combustion chamber 10 is divided into a so-called “primary” zone (or combustion zone) and a so-called “secondary” zone (or dilution zone) located downstream of the previous one (the downstream means with respect to a general axial direction of flow of the gases resulting from the combustion of the air / fuel mixture inside the combustion chamber and represented by the arrow D).
- the air that feeds the primary zone of the combustion chamber is introduced by a circumferential row of primary holes 28 formed in the inner annular walls 16 and outer 18 of the chamber over the entire circumference of these annular walls. These primary holes have a downstream edge aligned on the same line 28A.
- the air supplying the secondary zone of the chamber it borrows a plurality of dilution holes 30 also formed in the inner annular walls 16 and outer 18 all around the circumference of these annular walls.
- These dilution holes 30 are aligned in a circumferential row which is offset axially downstream from the rows of the primary holes 28 and they may have different diameters including alternating large and small holes. In the configuration illustrated in Figure 2, these dilution holes of different diameters, however, have a downstream edge aligned on the same line 30A.
- a plurality of cooling orifices 32 are provided in order to cool the inner and outer annular walls 16 and 18 of the combustion chamber which are subjected to the high temperatures of the combustion gases.
- the return elbow is also provided with such orifices.
- multi-perforation By multiple holes also called “multi-perforation", are distributed according to a plurality of circumferential rows spaced axially from each other. These rows of multi-perforation orifices generally cover the entire surface of the annular walls of the combustion chamber.
- the number and the diameter d1 of the cooling orifices 32 are identical in each of the rows.
- the pitch pl between two orifices of the same row is constant and may be identical or not for all the rows.
- the adjacent rows of cooling orifices are arranged so that the orifices 32 are staggered as shown in FIG. 2.
- the cooling orifices 32 generally have an inclination angle ⁇ 1 with respect to a normal N to the annular wall 16, 18 through which they are drilled.
- This inclination ⁇ 1 allows the air passing through these orifices to form a film of air along the hot side 16b, 18b of the annular wall.
- the inclination ⁇ 1 of the cooling orifices 32 is directed so that the air film thus formed flows in the flow direction of the combustion gases inside the chamber (represented by the arrow D ).
- the diameter d1 of the cooling orifices 32 may be between 0.3 and 1. mm (preferentially between 0.4 and 0.6 mm), the pitch p between 1 and 10 mm and their inclination ⁇ 1 between + 30 ° and + 70 °, typically + 60 °.
- the primary holes 28 and the dilution holes 30 have a diameter of the order of 4 to 20 mm.
- each annular wall 16, 18 of the combustion chamber may further comprise disposed directly downstream of these dilution holes 30 (but a similar configuration downstream of the holes).
- primary 28 is also possible to limit the rise of the thermal gradient at these holes and thus avoid the formation of cracks) and distributed along several circumferential rows from the upstream transition axis 30A, a plurality of additional cooling orifices 34
- the air film delivered by these additional orifices flows in a perpendicular direction due to their arrangement at 90.degree. ° in a plane perpendicular to this axial direction D of flue gas flow.
- This multi-perforation made perpendicularly to the axis of the turbomachine (in the following description, it will speak of multi-perforation gyratory as opposed to the axial multi-perforation of the cooling orifices) allows to bring these additional holes of the holes of dilution (or primary holes if necessary) and therefore limit the rise of the thermal gradient at these holes.
- the additional orifices 34 of the same row have the same diameter d2, preferably identical to the diameter d1 of the cooling orifices 32, are spaced by a constant pitch p2 which may or may not be identical to the pitch p1 between the cooling orifices 32 and have an inclination ⁇ 2, preferably identical to the inclination ⁇ 1 of the cooling orifices 32 but arranged in a perpendicular plane.
- these characteristics of the additional orifices 34 may, while remaining within the ranges of values defined above, be substantially different from those of the cooling orifices 32, that is to say that the inclination ⁇ 2 of the additional orifices of a
- the same row relative to a normal N to the annular wall 16, 18 may be different from that of the cooling orifices, and the diameter d2 of the additional orifices of the same row may be different from that of the cooling orifices 32.
- an optimum cooling around the dilution holes as primary holes is obtained by using the dynamic pressure on the cold side (between the casing and the wall of the chamber) while maintaining the effect of the hot-side gyration.
- multi-perforation holes 36 bent at an angle ⁇ greater than 90 ° in the wall of the chamber, so that they are fed by the total air pressure cold side, as for axial multi-perforation, while opening on the hot side as in multi-perforation gyratory.
- the holes are powered by the static pressure of the air between the housing 12 and the chamber wall while in the case of the multi -Perforation axial holes are powered by the total air pressure.
- the fact of being fed by the static pressure implies that the dynamic air pressure (total P - static P) is not used between the casing and the wall of the chamber. However, this dynamic pressure is even greater at the primary holes and dilution holes.
- the angle typically between 90 ° and 170 ° is taken between an input geometric axis Ae and an output geometric axis
- the output geometric axis (hot wall side hole axis) being inclined at an angle ⁇ 3 with respect to the normal N to the annular wall but in a plane itself inclined by an angle ⁇ in a so-called gyration direction at most perpendicular to the axial direction D of the gas flow combustion.
- this angle of turn ⁇ is between 50 ° and 90 °.
- These multi-perforation holes 36 have a diameter d3, preferably identical to the diameter d1 of the cooling orifices 32 and the inclination at the outlet ⁇ 3 is preferably identical to the inclination ⁇ 1 of the cooling orifices 32.
- input geometric axis may be straight (parallel to the normal N) or preferably have an inclination ⁇ 4 (preferably identical to the inclination ⁇ 1 of the cooling orifices 32) relative to this normal in the axial direction D of flue gas flow.
- these different characteristics can, while remaining in the ranges of values defined previously for the cooling orifices 32, be substantially different.
- each multi-perforation hole 36 may advantageously be variable, that is to say with a diameter d3, inclinations ⁇ 3 and ⁇ 4
- this lateral exchange surface (surface wetted by the air that passes through the hole) is identical for the 3 types of multi-perforation holes.
- the bent hole does not degrade the cooling of the wall by the forced convection of the air flowing through it.
- the air outlet of the multi-perforation hole 36 opening on the hot side may have a variable diameter d3 in the shape of a cone and therefore no longer be constant as before but with the diameter d3 increasing. by getting closer to this air outlet.
- the air outlet opening on the hot side can, after the bent portion, divide into two parts so as to increase the exchange surface between the cooling air and the wall.
- the diameter d3 will preferably be identical throughout the multi-perforation hole 36, but the angles ⁇ 1 and ⁇ 2 between the input geometrical axis and the respective output geometrical axes of the two parts after the bend may be identical as illustrated or illustrated. still different.
- the air outlets forming the end portion of the hole may also have a variable diameter.
