Definitions
- the present invention relates to the field of aerospace nacels intended for coaching aircraft engines, and particularly to turbofan engines.
- a nacelle which generally comprises for this purpose an upstream portion forming a nose surrounding the air inlet, followed by an intermediate portion forming a cover protecting the fan casing, then a downstream portion may include thrust reversal means.
- the cumulative manufacturing and assembly tolerances may sometimes cause radial recesses between the fan cowl cover and the panel or panels of the downstream portion, and more particularly the panels external thrust reversers.
- Such recesses may cause aerodynamic performance losses of the nacelle, but also expose the upstream edges of the thrust reverser panels to an erosion or delamination phenomenon.
- the objects assigned to the invention therefore aim at overcoming the aforementioned drawbacks and at proposing a new nacelle arrangement which makes it possible to adjust in a simple, reproducible manner and at a lower cost the downstream panels, and more particularly the external panels of the thrust reversers flush with the fan case cover.
- a centraliser intended to integrate a turbojet engine nacelle which has at least one fan casing cover and at least one downstream external panel, of the type of external thrust reverser panel. , to be placed longitudinally in a row, said centralizer being characterized in that it comprises, in one piece:
- ⁇ a base for attaching the centering device to the fan casing ⁇ a first positioning branch, integral with the base, projecting upstream, so as to form, relative to the axis of the nacelle, a first radial abutment designed to guide the housing cover of blower, ⁇ a second positioning branch, integral with the base, projecting downstream, so as to form, relative to the center axis of the nacelle, a second radial abutment designed to guide the outer panel downstream, so as to ensure the positioning of said downstream outer panel substantially in the flush extension of the fan case cover.
- turbojet engine nacelle which comprises at least one such centraliser, and preferably a plurality of such centrers distributed around its director axis.
- the use of a monolithic centering device makes it possible to have a set of radial centering abutments attached to the same base, that is to say to the same common trunk, whose radial abutments form the branches, which considerably reduces the size range, in particular radial, between the first abutment providing support for the fan casing cover and the second abutment providing support for the external panel of the thrust reverser.
- the use of the centralizer according to the invention amounts to creating a common reference spacer, and more particularly radial, between the first stop and the second stop, and therefore between the fan case cover and or the thrust reverser panels, such that these different members can be easily centered relative to each other, at radial distances well controlled relative to one another.
- Figures 1 and 2 illustrate, respectively in perspective views of three-quarter front and long itud inal section, the principle of implementation of centrers according to the invention within a nacelle turbojet turbofan.
- Figure 3 illustrates, in a partial perspective view, the detail of the implementation of a centraliser according to the invention on a support member connected to the fan casing.
- Figure 4 illustrates, in a partial view in longitudinal section, the locating detail of the centraliser of Figure 4 within a nacelle according to the invention.
- FIG. 5 illustrates, in a partial view in longitudinal section, the implantation detail of another variant of a centraliser within a nacelle according to the invention.
- FIGS. 6, 7 and 8 illustrate, respectively in front views (from upstream), sideways in longitudinal section, and back views (from downstream), the centralizer variant implemented in FIGS. 4.
- the invention relates to a nacelle 1 for careening a reactor, of the turbojet type, and more particularly a dual flow reactor.
- the nacelle 1 has an external structure 2 which comprises an upstream portion 3 forming an air inlet, an intermediate portion 4 whose inner skin 5 is formed by the blower housing 6 of the turbojet engine and whose outer skin is formed by the fan casing cover 7 (usually called “fan cowl”), then a downstream portion 8 which may preferably incorporate inversion means thrust.
- the nacelle 1 also comprises an internal structure 9 which comprises a fairing 10 of the engine 1 1 of the turbojet engine.
- the figures will be associated with a reference to three axes X, Y, Z, these axes being respectively representative of the longitudinal, transverse, and vertical directions of the nacelle, when the latter is installed on an aircraft.
- the longitudinal axis X is parallel, and preferably coincidental, with the director axis A of the nacelle 1, which coincides in turn substantially with the axis of rotation of the reactor, and more particularly of the fan 6.
- the nacelle 1 has substantially a cylindrical shape of revolution about said director axis A.
- R M AX may be noted the maximum overall radius of said form of revolution.
- the upstream-downstream direction corresponds to the direction of propulsive flow of the reactor, oriented substantially along the longitudinal direction of the nacelle 1 corresponding to the steering axis A, from the leading edge of the nacelle 1 towards its trailing edge.
- the invention relates more particularly to a centralizer 12 intended to integrate a nacelle 1 of a turbojet, as described above, nacelle 1 i i has at least one fan casing cover 7 and at least one downstream external panel 13, the panel type external thrust reverser, said cover 7 and said outer panel 13 to be placed longitudinally in a row.
- the invention may in particular be applied to a so-called “smooth" nacelle 1 in which the downstream outer panel 13 is fixedly mounted, in an invariant position, with respect to the hood 7.
- said invention will preferably relate to a nacelle 1 d s sl aq uel lele pan n ea u extern e ava l 1 3 form pa nn ea u external thrust reverser, mounted movably in axial sliding relative to the hood 7 , and, more generally, with respect to the fairing 10 of the engine 1 1.
- Said external thrust reverser panel to which the downstream outer panel 1 3 can be assimilated in what is known by convenience of description, may in particular be of the "O-duct” type, that is to say forming a one-piece quasi-annular shell which extends over the circumference of the nacelle, from one edge to the other of the fixing mast (or “pylon", not shown), or even of the "D-duct” type , that is to say fractionated into a plurality of panels, preferably two panels each covering substantially half-circumference of the nacelle 1.
- the centralizer 12 comprises, in one piece: ⁇ a base 14 for fixing the centralizer 12 to the fan casing 5,
- the centralizer 12 makes it possible to produce, by means of the same piece forming a common reference frame, both a radial centering of the ca pot 7 of ca rter of blow a nte, thanks to the first bra n ch ed positioning 1 5, and a radial retention, of the anti-scoop type, of the downstream outer panel 13, thanks to the second positioning branch 16.
- the apparent radially external surfaces of the hood 7 and of the downstream panel 1 3 can advantageously be flush, in the extension of one another, without marking a step or any radial recess.
- the first positioning branch 15 and the positroning second beam 16 form two shoulders substantially transverse to the base 14, and more particularly substantially orthoradial, able to withstand the radial forces exerted respectively by the cover 7 and the downstream panel 13, and necessary for centering and maintaining these centers.
- the fan casing cover 7 can thus axially overlap the first branch 1 5, the partial recovery of these elements, on a section of the director axis A, ensuring the desired centering.
- the outer downstream panel may thus axially overlap the second branch 1 6, the partial recovery of these elements, on a (other) section of the director axis A, ensuring the desired centering.
- Said first and second branches 15, 16 will preferably originate on the base 14 in the portion located in the half, the third, or preferably the radially outer quarter of the centralizer 12, that is to say in the half , the third or even the upper quarter of said centering device in FIGS. 4 to 8.
- the second positioning branch 16 (downstream) will also preferably be located in a radially reentrant position relative to the first branch 15 (upstream), that is to say closer to the director axis A.
- the centralizer 12 may thus have substantially the shape of an inverted boot, the base 14 will form the rod, the first leg 15 the sole, and the second branch 16 a spur.
- the base 1 4 is adapted to extend substantially radially between the fan casing 5 and the fan casing cover 7.
- Said base 14 may be attached to any fastener 17, 18 secured to the fan casing 5, and in particular to a radial fixing lug 17 and / or to a flange 18 fixed to said housing 5 or integral with the latter.
- the centralizer 12 will rest on and will be fastened to the fan casing 5 on the one hand by its first branch 15, which may advantageously support radial support, preferably by its radially inner face, and where appropriate by by means of an adjustment wedge 1 9, against an L flap 20 of the flange 1 8 of substantially conjugate shape, and secondly by its base 14, which will apply axially against the said collar 1 8 ( Figure 5) and / or against a bracket 17 ( Figure 3).
- first branch 15 may advantageously support radial support, preferably by its radially inner face, and where appropriate by by means of an adjustment wedge 1 9, against an L flap 20 of the flange 1 8 of substantially conjugate shape, and secondly by its base 14, which will apply axially against the said collar 1 8 ( Figure 5) and / or against a bracket 17 ( Figure 3).
- the fan casing cover 7 is radially bearing against a radially outer bearing surface 15E of the first positioning arm 15, while the downstream outer panel 13 has a retaining hook 21 which comes to bear radially against a radially internal bearing surface 161 of the second positioning arm 16 .
- the cover 7 will thus rely, by its inner face 71, against the centralizer 12, against the radially outer bearing surface 15E of the first branch 15, and therefore tend to exert on said first branch 15 a radial force substantially centripetal.
- downstream outer panel 1 3 will tend to exert, via the retaining hook 21, a radial centrifugal force on the second branch 16.
- downstream outer panel 13 is formed by an external thrust reverser panel which is mounted movably along the directing axis A of the nacelle 1.
- the downstream outer panel 13 can then be provided with a retaining hook 21 which is radially recessed and has a docking ramp 22 that is inclined radially so as to establish a prog ress contact with the second pos e bra nch e ition n em ent 16, and more particularly its radially internal bearing surface 161, when said downstream outer panel 13 approaches the axial centering device 12 axially.
- a retaining hook 21 which is radially recessed and has a docking ramp 22 that is inclined radially so as to establish a prog ress contact with the second pos e bra nch e ition n em ent 16, and more particularly its radially internal bearing surface 161, when said downstream outer panel 13 approaches the axial centering device 12 axially.
- the centralizer 12 can therefore advantageously perform a role of dynamic centering, in flight, vis-à-vis the thrust reversers.
- said centralizer 12 equips a nacelle 1 provided with thrust reversers or a nacelle 1 smooth, said centralizer 12 can advantageously fulfill the role of static centering, during the assembly of the nacelle 1, by guiding and stabilizing the downstream outer panel 13 when it is put in place.
- the centralizer 12 will be made of a sufficiently rigid material to give the first and second positioning legs 1 5, 1 6 their structural stiffness, which allows them to withstand in particular the radial components of the support forces exerted on they cover the hood 7 and the downstream panel 1 3, and therefore perform their role of centering arms, and this as well at rest, during assembly, in flight, especially during reconfigurations thrust reversers.
- said centralizer 12 may thus be made of a light metal material, for example an aluminum alloy.
- the centralizer may also include reinforcing ribs
- the first positioning leg 15 carrying a receiving surface 24 against which the fan casing cover 7 is intended to come radially in abutment, said receiving surface 24 is curved radially towards said cap 7.
- said receiving surface 24 substantially corresponds to a sphere portion.
- the receiving surface 24 is located radially outwardly of the first leg 15, in order to receive and support the inner face 71 of the hood.
- the radius R24 of the receiving surface 24 can then correspond substantially to the distance from said receiving surface 24 to the director axis A, and more particularly to the radius of the outer circumference of said receiving surface 24 around said director axis. AT.
- the curved, and preferably spherical, nature of the receiving surface 24 against which the cover 7 bears directly improves the contact between the fan casing cover 7 and the centralizer 12, in particular allowing the assembly to better accommodate the angular tolerances of positioning said cover 7 relative to the fan casing 5 and the centralizer 12.
- the curved receiving surface 24 is made directly in the material constituting the first positioning branch 15.
- the receiving surface can be directly shaped, and for example molded or machined, in the first branch 15, and preferably at the radially outer surface 1 5E of the latter, so that the cover 7 can come into direct contact with said first branch 15.
- the nacelle 1 may be designed so that the fan casing cover 7 comes into direct contact with the first positioning branch 15, that is to say the monolithic body of the naked centering device 12, said first branch 15, and more preferably its radially outer bearing surface 15E, forming in itself the reference bearing surface for centering the cover 7.
- the nacelle 1 may preferably be designed in such a way that the downstream external panel 13 comes into direct contact with the second positioning branch 16. That is to say, the monolithic body of the centralizer 1 2 naked, lad ite second branch 1 6, and more preferably its radially internal bearing surface 1 61, forming in itself the bearing surface, and more particularly the radial retaining surface, allowing the centering of said downstream panel 13, where appropriate via the hook 22 on board by the latter.
- the bodies to be centered namely the cover 7 and the downstream panel 13, can thus radially take their respective supports on the same reference solid, which minimizes and thus optimizes the chain of dimensions between said supports.
- the convex convex surface 24 is formed by an attached engagement wedge 25 fixed to a bearing surface, here preferably the radially outer surface 15E, the first positioning branch 15, so as to be able to intervene radially between said bearing surface 15E of the first branch and the corresponding face, here preferably the radially inner face 71 of the fan casing cover 7.
- Such engagement wedge 25 will advantageously be sandwiched radially, in the direction of its thickness, on one side directly by the plate (bearing surface 1 5E) provided by the first branch 15, and on the other side directly by the inner face 71 of the cover 7 which is located in radial vis-à-vis del ad ite prem i re b ra nch e 1 5, ask ax l ax ent overlapping therein.
- Said shim 25 may for example be screwed on the radially outer bearing surface 15E of the first branch 15, where appropriate by the same screws as those for fixing said first branch 15 to the flap 20 of the collar 18.
- the said engagement gap 25 may moreover preferably form a sliding interface, of the anti-friction lining type, making it possible to reduce the frictional resistance of the cover 7 on the centralizer 12 during the positioning of said cover 7.
- the first branch 15 may comprise an anti-friction lining 25, 26 intended to facilitate the sliding of the fan case cover 7 on the receiving surface 24 of said first branch 15, said lining being made of a material with a low coefficient of friction, for example a polymer such as PTFE.
- Said lining material may take the form of a coating 26, if the receiving surface is shaped directly in the first leg 15, or even a shim 25, as detailed above.
- the presence of such a garniture facilitates the pouring of the cover 7 on the centralizer 1 2, avoiding jamming during assembly.
- the constituent materials of the cover 7 on the one hand, and the centralizer 1 2 on the other hand may be chosen so as to present, one towards the other, a low coefficient of friction.
- the cover 7 may be made of carbon fibers and the centralizer 12 in another material, for example aluminum alloy.
- the invention furthermore relates, as such, to a nacelle 1 for a turbojet engine which comprises at least one centralizer 12 according to the invention, and preferably a plurality of centralizers 12 according to the invention distributed around its director axis A, such that this is illustrated in Figure 1.
- the number of centreu rs 1 2 and their distribution, possibly regular, on the circumference of the nacelle 1, may of course depend on the dimensions of said nacelle, as well as radial forces, including pressure or depression, that will have to support the fan casing cover 7, the external downstream panel 1 3, and therefore the said centralizers 12.
- the first positioning branch 15 will have a firewall 27 which comes into contact with the corresponding surface, here the radially inner face 71 of the fan casing cover 7, so as to ensure the fireproofness of the compartment 28 which must accommodate the blower 6.
- said firewall seal 27 may be of the annular lip seal type.
- Led it 27 can advantageously be plaq ued and clamped radially between the first branch 15 and the flange flange 18.
