Abstract
Description
- The invention relates to the field of bypass turbojets and, more particularly, the afterburner devices provided in turbojet engines of this kind.
- In a bypass turbojet of the type shown in
FIG. 1 , the air flow drawn in by a fan 1 supplies a low-pressure compressor 2. A first part of the compressed-air flow supplies a high-pressure compressor 3, while a second (complementary) part is intended to supply afirst passage 4 further downstream defined between an outerannular casing 5 and a first inner annular casing 6 (usually referred to as a flow separator and serving to separate the primary flow from the secondary flow before they are mixed together) of anafterburner device 7. The compressed-air flow through the high-pressure compressor 3 supplies a combustion chamber 8 which supplies exhaust gas to aturbine 9 comprising a high-pressure stage followed by a low-pressure stage and the outlet of which supplies asecond passage 10 defined between the first inner annular casing 6 (or flow separator) and a second inner annular casing 11 (usually referred to as an exhaust cone) of theafterburner device 7. - The exhaust gases supplying the
second passage 10 are at an elevated temperature and form what is usually referred to as a primary flow (or hot flow). The air supplying thefirst passage 4 is at a substantially lower temperature than that of the primary flow and forms what is usually referred to as a secondary flow (or bypass flow). - The
afterburner device 7 allows a second combustion operation to be carried out by virtue of the injection of fuel into the primary and secondary flows. Part of this injection operation is effected with the aid of aburner ring 12 placed in the vicinity of the first inner casing 6 (or flow separator) in the passage for the secondary flow or for the primary flow. More precisely, theburner ring 12 allows part of the fuel to be injected in a homogeneous manner and the flame to be stabilised. - According to the embodiment selected, the
burner ring 12 is carried bysupport arms 13, also referred to as “flameholder arms”, positively connected to the outer casing by means of a support element and/or to the first inner casing by means of fixing means. - The positive connection of the arms to the outer casing by means of a support element is described, in particular, in the
document FR 2 699 226. As the support element and the associated arm are positively connected together in a region traversed by the primary flow, the components ensuring this positive connection are therefore subjected not only to considerable thermal stresses, but also to stresses referred to as “airflow pressure”. Each arm moreover forms together with a burner ring portion a monobloc sub-structure which is particularly difficult to produce as a result, in particular, of the presence of several rounded edges. - The positive connection of the arms to the first inner casing by means of fixing means is described, in particular, in the documents U.S. Pat. No. 5,103,638,
GB 2 295 214, U.S. Pat. No. 5,022,805 and U.S. Pat. No. 5,090,198. In each of these documents, the arms made of composite material are supposed to be positively connected to a metal inner casing placed at the interface between the primary and secondary flows. This results in a difference in thermal expansion between the arms and the casing, compensated for by the use of complex fixing means and interface components. - It is also proposed in the
document FR 2 699 227 to form a monobloc structure consisting of the outer and inner casings, the burner ring and the arms. However, a structure of this kind is difficult to produce, particularly as a result of the fact that different materials have to be used for the “cold” components and the “hot” components. Maintenance operations are moreover difficult as a result of the monobloc nature of this structure and damage to one of its components will necessitate the complete replacement thereof. - The aim of the invention is therefore to improve the situation.
- To this end, it proposes a support (flameholder) aim for an afterburner device comprising, as indicated in the introductory part, first and second inner annular casings defining a passage for the primary flow and an outer annular casing defining together with the first inner annular casing a passage for the secondary flow.
- This arm is characterised in that it comprises a monobloc structure made of composite material including two integral walls, on the one hand, designed to define a groove having a substantially V-shaped profile and, on the other hand, including first end parts joined together and adapted to define a foot and second end parts adapted each to define at least one flange intended to be positively connected to the outer casing.
- The arm according to the invention may include other features which can be taken separately or in combination, in particular:
-
- the spacing of its two walls may not be constant between their first and second end parts, such that the profile of the groove can vary. In this case, the spacing varies, e.g. substantially continuously, increasing from the first end parts to the second end parts, such that the profile of the groove can vary substantially continuously;
- the thickness of its two walls may not be constant between their first and second end parts. In this case, e.g. the thickness of the two walls is greater at their second end parts in order to increase their resistance;
- its two walls may each include a notch at the same selected level so as to define a housing which can receive a burner ring support. E.g. this burner ring support is positively connected to the two walls in the vicinity of their notches, possibly with the aid of rivets. The notches may moreover be formed in a zone of a part of the two walls intended to be placed in the passage for the secondary flow. This zone is then preferably placed in the vicinity of the first inner casing;
- each flange can be positively connected to the outer casing by means of at least one bolt, with the interposition of a backing plate on the side exposed to the secondary flow;
- the monobloc structure can be made of a composite material having a ceramic matrix.
- The invention also relates to an afterburner device of the aforementioned type for a bypass turbojet, comprising at least three support arms of the type described hereinbefore according to one of the preceding features, positively connected to its outer casing.
- A device of this kind may comprise, e.g. in its passage for the secondary flow an insulating liner defining together with the outer casing an afterburner jet pipe for part of the secondary flow. In this case, the burner ring support of each support arm is preferably installed at a level between the respective levels of the insulating liner and the first inner casing.
- Other features and advantages of the invention will be clear from the detailed description hereinafter and from the accompanying drawings, in which:
-
FIG. 1 is a diagrammatic longitudinal section of a bypass turbojet; -
FIG. 2A is a first perspective view of an embodiment of an arm according to the invention, before the fixing of a burner ring support; -
FIG. 2B is a second perspective view of the arm ofFIG. 2A ; -
FIG. 3 is a perspective view of an embodiment of an arm according to the invention, after the fixing of a burner ring support; -
FIG. 4 is a top view of the arm ofFIG. 3 ; -
FIG. 5 is a sectional view along the axis V-V of the arm ofFIG. 3 ; -
FIG. 6 is a sectional view along the axis VI-VI of the arm ofFIG. 3 ; -
FIG. 7 is a side view of the arm ofFIG. 3 , after the positive connection to the outer casing of the afterburner device, and -
FIGS. 8A and 8B are two perspective views showing the assembly ofFIG. 7 from two different angles. - The accompanying drawings may serve not only to complete the invention, but also to help to define it, where appropriate.
- The invention relates to a support flameholder arm for an afterburner device of a turbojet engine of the type described in the introductory part with reference to
FIG. 1 . - A
support arm 13 according to invention will now be described with reference firstly toFIGS. 1, 2A and 2B. - The support arm (or flameholder arm) 13 shown in
FIGS. 2A and 2B is in the form of a monobloc structure made of a heat-resistant composite material. This composite material preferably has a ceramic matrix. E.g. the monobloc structure is made from a fibre preform, in particular of silicon carbide or carbon, into which a ceramic matrix in the liquid or gaseous phase is infiltrated. The monobloc structure can thus be made, e.g. with CERASEP® 410-12. - The use of a composite material is particularly advantageous as a result of the fact that it allows for a weight gain (compared to metal materials) and an increase in service life, particularly in the event of elevated operating temperatures.
- The monobloc structure includes two substantially
symmetrical walls groove 16, the profile of which is substantially V-shaped in cross section. - These two
walls first end parts 17 joined together and adapted to define a preferably bevelledfoot 18 so as to promote the primary flow. - Each
wall second end part 19 opposite thefoot 18 and adapted to define at least oneflange annular casing 5, as will be seen hereinafter with reference toFIG. 7 . In order to allow for this positive connection, e.g. with the aid of bolts, eachflange orifice 22, and preferably at least two, as shown inFIG. 2B . - In addition, each
wall notches 23 define a housing in which aburner ring support 24 can be placed, as shown inFIG. 3 . - The level at which the
notches 23 are formed is selected as a function of the intended location of the burner ring. In the example shown, they are provided in the vicinity of the second ends 19 so that the burner ring is placed in theduct 4 for the secondary flow. However, in a variant, they could be placed in a central part of thewalls foot 18 so that the burner ring is placed in theduct 10 for the primary flow. - E.g., as shown in
FIG. 3 , theburner ring support 24 includes acentral part 25 defining a V-shaped groove open on two sides and extended substantially perpendicularly towards the rear by twolateral parts 26 positively connected to inner faces of the twowalls notches 23. This positive connection can be effected, e.g. with the aid ofrivets 27. - The
burner ring support 24 is made, e.g. of a metal material when it is situated in the “cold” secondary zone. However, it can also be made of a composite material, particularly when it is installed in the “hot” primary zone. - So as to allow for the positive connection of the burner ring to the
burner ring support 24, the latter preferably includes at least one throughorifice 28 on each of the two wings forming itscentral part 25. - As shown by the sectional views along the axes V-V and VI-VI of
FIG. 3 shown inFIGS. 5 and 6 and by the top view shown inFIG. 4 , the spacing between the twowalls foot 18 to thesecond end parts 19. In other words, the V-shaped profile of thegroove 16 can vary. More precisely, the spacing in this case increases substantially continuously from thefoot 18 to thesecond end parts 19. - Although not shown in the figures, the thickness of the two
walls foot 18 to thesecond end parts 19, as it may be advantageous for part of thesupport arm 13 subjected to higher stresses than the other parts to be reinforced. Excessive thickness at thesecond end parts 19 therefore means that they will be more resistant to thermal stresses and to stresses due to airflow pressure. - An
afterburner device 7 of a bypass turbojet includes at least threesupport arms 13 of the type described hereinbefore, and more preferably at least four. In some turbojet engines, the number of arms may be equal to nine (9). - An example of the positive connection of a
support arm 13 to the outerannular casing 5 of anafterburner device 7 will now be described with reference toFIGS. 7, 8A and 8B. - As described hereinbefore, each
support arm 13 is positively connected by means of itsflanges annular casing 5. - As the positive connection is effected directly to the outer
annular casing 5 in a “cold” environment (typically less than approximately 200° C.), there is no problem with a difference in thermal expansion between thesupport arm 13 and the outerannular casing 5. It is therefore possible to use particularly simple fixing (or positive connection) means,e.g. bolts 29. It is possible to use, e.g. two bolts 29 (and a minimum of one) in order to fix eachflange - Once positively connected, each arm extends substantially in a radial direction in relation to the axis of rotation of the
turbine 9, also forming the axis of revolution of the outer 5 and inner 6 and 11 casings. It will be recalled that the expressions “inner casing 6” and “inner casing 11” as used here refer to what the person skilled in the art refers to respectively as the flow separator and the exhaust cone. - As shown in
FIG. 7 , theafterburner device 7 may include an insulatingliner 32 interposed between the first inner annular casing 6 (or flow separator) and the outerannular casing 5 and defining together with the latter anafterburner jet pipe 33 in which at least part of the secondary flow circulates. This insulatingliner 32 is generally a corrugated, multi-perforated plate intended to contain the afterburning gases (just like the walls of a principal chamber) and to protect the outerannular casing 5 from the hot flow. If an insulatingliner 32 of this kind is present, thenotches 23 in thewalls support arm 13 are formed at a level selected in such a manner that theburner ring support 24 is at least partially surrounded by the intermediateannular casing 32 and the first inner annular casing 6 (or flow separator). - As shown more clearly in
FIG. 3 , a reinforcing and/orprotective backing plate 30 can moreover be placed under the outer face (opposite the outer casing 5) of eachflange flanges support arm 13 to mechanical stresses. Thisbacking plate 30 is preferably made of metal. - It should be noted that the V-shaped profile and the shape of the
foot 18 of eachsupport arm 13 are selected so as to optimise the primary flow (arrow F1 inFIG. 7 ) and the secondary flow (arrow F2 inFIG. 7 ) and therefore to obtain aerodynamic behaviour corresponding to the expected performance. - A
support arm 13 may moreover house an inner carburation device in itsgroove 16. As a result of the composite material used to produce thesupport arm 13, the latter can moreover withstand elevated temperatures, so that it is not necessary to provide it with an inner ventilation device intended to cool the component from its leading edge traversed by the primary flow. - The invention is not limited to the embodiments of the support arm and afterburner device described hereinbefore merely by way of example, but covers any variants which may be envisaged by the person skilled in the art within the scope of the claims hereinafter.
