Definitions
- the present invention relates generally to an aircraft engine attachment pylon, such as a turbojet engine.
- This type of attachment pole also called “EMS” (of the English “Engine Mounting Structure"), allows to suspend the turbojet below the wing of the aircraft, or to mount the turbojet engine above of this same wing, via a plurality of engine fasteners.
- Such a rigging mast is in fact provided to form the connecting interface between an engine such as a turbojet and a wing of the aircraft. It makes it possible to transmit to the structure of this aircraft the forces generated by its associated turbojet, and also authorizes the routing of fuel, electrical, hydraulic and air systems between the engine and the aircraft.
- the mast has a rigid structure, often of the "box" type, that is to say formed by the assembly of upper and lower spars and two side panels connected together by the intermediate transverse ribs.
- the mast is provided with a mounting system interposed between the turbojet engine and the rigid structure of the mast, this system generally comprising at least two engine attachments, generally at least one front attachment and at least one rear attachment.
- the mounting system comprises a device for taking up the thrust forces generated by the turbojet engine.
- this device takes for example the form of two lateral rods connected on the one hand to a rear part of the fan housing of the turbojet, and on the other hand to a rear attachment fixed to the housing thereof.
- the attachment mast also includes a second mounting system interposed between the rigid structure of the mast and the wing of the aircraft, the second system usually consisting of two or three fasteners.
- the mast is provided with a secondary structure ensuring the segregation and maintenance of the systems while supporting aerodynamic fairings.
- a conventional attachment mast of the prior art is equipped with a rear attachment usually secured to the lower spar of the box.
- This specificity implies that it is necessary to have access to the interior of the box to be able to assemble the rear attachment.
- the accessibility inside the mast is often very limited, which inevitably causes mounting difficulties, penalizing in terms of cost and time.
- the object of the invention is therefore to propose an aircraft engine attachment pylon which at least partially overcomes the drawback mentioned above relating to the embodiments of the prior art, and also to present an aircraft having at least such a mast.
- the subject of the invention is an aircraft engine attachment pylon, this box-type mast being formed by the assembly of an upper spar, a lower spar, two lateral panels and ribs. transversal connecting the longitudinal members and panels, the mast also comprising a rear engine attachment equipped with a rear attachment body.
- the rear engine attachment is provided with two lateral fittings each comprising a longitudinal portion in contact with an inner face of the side panel associated with it and fixedly mounted on the same inner face, and a transverse portion comprising an attachment interface of the rear attachment body, this transverse portion being arranged to pass through a notch made on the associated side panel.
- the proposed invention makes it possible to provide easy mounting of the rear engine attachment equipping the attachment pylon, since the fastening interfaces of the rear attachment body are therefore located outside the box.
- the longitudinal portion of the fitting lateral side preferably closes its associated notch, it is understood that the transverse portion is projecting from the side panel outwards, through the notch provided for this purpose.
- this particular configuration makes the mounting interface directly and easily accessible for an operator located near the box, and desiring for example to mount bolts at the same attachment interface.
- the lower spar has a constriction constituted by two recesses serving respectively to accommodate the two side fittings of the rear engine attachment.
- the lower spar is bent in the transverse direction at the rear engine attachment in order to compensate for the thickness of the longitudinal portion of the side fittings of the rear attachment.
- the recesses combined with the presence of the two side fittings provide a box whose two side surfaces have a substantially straight continuous shape, which also allows the optimization of aerodynamic shapes of the nacelle at the right of these fittings.
- this specificity generates gains in terms of total mass of the attachment pylon, since the intended restriction reduces the width of the rear attachment body located below the lower spar, as well as that of the box at the rear engine mount.
- the indentation of each of the two side panels is open downwards.
- the lower spar preferably comprises two lateral flanges mounted respectively on the two side panels, which allows the longitudinal portion of each of the two side fittings of the rear attachment to be interposed between the two side flanges. one of the two side wings and one of the two side panels. As such, note that it is even sought a contact between the longitudinal portion and the last two elements cited.
- each of the two side fittings of the rear attachment comprises a fixing plate defining the attachment interface of the rear attachment body, as well as reinforcing ribs integral with the fixing plate and of the longitudinal portion.
- the reinforcing ribs are oriented in parallel planes defined by a transverse direction and a vertical direction of the mast.
- the attachment interface of each of the two side fittings of the rear attachment takes the form of a flat surface oriented in a plane defined by the transverse direction and a longitudinal direction of the mast.
- each of the two side fittings of the rear attachment is made in one piece, and preferably made of titanium. It is stated that the rear attachment is preferably designed so as to define two half-fasteners each capable of ensuring the recovery of forces exerted in a vertical direction of the mast.
- this rear engine attachment further comprises a first shear pin capable of ensuring recovery forces exerted in the transverse direction of the mast, the first shear pin passing through the lower spar and having a lower end housed in the rear attachment body, the lower end being provided with a bore through which a first pin also traversing the rear attachment body.
- This arrangement thus provides not only the possibility for the rear attachment to resume the forces exerted in the transverse direction of the mast, but also allows, through the cooperation between the bore and the pin through the rear attachment body, to resume efforts exerted in the vertical direction of the mast in case of failure / breakage of one of the two side brackets.
- This clever solution therefore makes it possible to ensure a so-called "Fail Safe” function for the transmission of forces in the vertical direction, without this leading to a significant complexity of the body design.
- rear attachment In particular, this last piece can always be made in one piece, preferably in titanium, which advantageously generates a gain in terms of weight and cost.
- the rear engine attachment further comprises a second shear pin capable of ensuring, only in case of failure occurring at the level of the first shear pin, the recovery of the forces exerted in the transverse direction of the mast, second shear pin passing through the lower beam and having a lower end accommodated in the rear attachment body, the lower end being provided with a bore through which a second pin also passes through the rear attachment body. Therefore, it should be understood that this second shear pin ensures the function "Fail Safe" for the transmission of forces exerted in the transverse direction, which implies that the pin is preferably mounted with play in a housing of the rear attachment body.
- the second pin cooperating with the bore makes it possible to provide a second function "Fail Safe" for the transmission of forces exerted according to the direction vertical, which advantageously generates the presence of a separate security for each of the two side fittings of the rear attachment.
- the two shear pins are preferably preferably positioned near the two lateral fittings.
- the rear engine attachment further comprises a first annex pin passing through the lower beam and having a lower end housed in the rear attachment body, this lower end being provided with a bore traversed by the first pin, and that this attachment also comprises a second annex pin passing through the lower beam and having a lower end housed in the rear attachment body this lower end being provided with a bore traversed by the second pin.
- first and second pins are oriented in the longitudinal direction of the mast.
- first and second shear pins and the first and second auxiliary pins each have an upper end passing through the same transverse rib of the mast.
- the invention also relates to an aircraft comprising at least one attachment mast such as the one just presented.
- FIG. 1 shows a partially schematic side view of an engine assembly for aircraft, comprising an attachment pylon according to a preferred embodiment of the present invention

- FIG. 5 represents a sectional view taken along line V-V of FIG. 3.
- a motor unit 1 for an aircraft intended to be fixed under a wing 3 of this aircraft (not shown) is shown, this assembly 1 comprising an attachment mast 4 according to a preferred embodiment of the present invention.
- the engine assembly 1 is composed of a motor such as a turbojet engine 2 and the attachment pylon 4, the latter being provided in particular with a plurality of engine fasteners 6, 8, 9 and a structure rigid 10 carrying these same fasteners.
- the assembly 1 is intended to be surrounded by a nacelle (not shown), and that the attachment mast 4 comprises another series of fasteners
- X is the longitudinal direction of the mast 4 which is also comparable to the longitudinal direction of the turbojet engine 2, this direction X being parallel to a longitudinal axis 5 of the turbojet engine 2.
- Y is the direction transversely oriented with respect to the mast 4 and also comparable to the transverse direction of the turbojet 2
- Z is the vertical or height direction, these three directions X, Y and Z being orthogonal to one another.
- front and rear are to be considered in relation to a direction of advancement of the aircraft encountered following the thrust exerted by the turbojet engine 2, this direction being represented schematically by the arrow 7.
- the rigid structure 10 is in the conventional form of a box formed by an upper spar 18 and a lower spar 20 extending both in the direction X and substantially in an XY plane or slightly inclined relative to the latter, as well as two lateral panels 22 (only one being visible in Figure 1) extending both in the direction X and substantially in a plane XZ.
- transverse ribs 24 arranged in YZ planes and spaced longitudinally reinforce the rigidity of the rigid structure 10. It is noted as an indication that the elements 18, 20, 22 can each be made of one piece, or by joining joined sections.
- the turbojet engine 2 has at the front of a large fan casing 12 delimiting an annular fan duct 14, and comprises a rearward central casing 16 of smaller size, enclosing the core of the fan. this turbojet. Finally, the central casing 16 is extended towards the rear by an ejection casing 17 of larger size than that of the casing 16.
- the casings 12, 16 and 17 are of course integral with each other.
- the plurality of engine attachments is constituted by a front engine attachment 6, a rear engine attachment 8 forming in fact two rear half-fasteners, and a fastener 9 forming a device.
- the device 9 takes for example the form of two lateral rods (only one being visible because of the side view) connected to a part of a rear portion of the fan casing 12, and secondly to a rudder mounted on the rear attachment 8.
- the rear ends of these rods could alternatively be connected to a rudder positioned forward relative to the rear attachment.
- the front engine attachment 6, secured to the pyramid 15 of the rigid structure 10 and to the fan casing 12, is conventionally designed so as to be able to take up only the forces generated by the turbojet engine 2 in directions Y and Z, and therefore not those being exercised in the direction X.
- this front attachment 6 preferably enters an inner portion of the fan casing which carries fixed blades thereof, and being located near a front end of the central casing .
- the rear engine attachment 8 constitutes a feature of the invention and will be more fully detailed with reference to FIGS. 2 to 5. It is generally interposed between the ejection housing 17 and the rigid structure 10 of the mast. It is in turn designed to form two half-fasteners arranged symmetrically with respect to a plane P defined by the axis 5 and the direction Z, each of these half-fasteners being designed so as to be able to take up forces generated by the turbojet engine 2 in the direction Z, but not those operating in the X and Y directions. However, it can be provided that this rear attachment is also able to resume, with a central portion, the forces generated by the turbojet engine 2 according to Y direction.
- the recovery of the forces exerted in the direction X is effected by means of the fastener 9
- the recovery of the forces exerted in the direction Y is carried out using the front attachment 6 and the central portion of the rear attachment
- the recovery efforts in the direction Z is carried out jointly with the aid of the front attachment 6 and two rear half-fasteners.

- it comprises a lateral fitting 26 composed of a longitudinal portion 28 and a transverse portion 30, and preferably has a plane of symmetry oriented in the directions Y and Z.
- the longitudinal portion 28 therefore extends according to the direction X substantially in a plane XZ, and comprises an inner face 32 in contact with a lateral flange 34 of the lower spar 20.
- the flange 34 is also substantially oriented according to an XZ plane so as to allow the assembly of the side panel 22 on the spar 20, for example by riveting or splicing.
- the transverse portion 30 comprises a fixing plate 36 defining an attachment interface 38 of a rear attachment body (not shown in this Figure 2), this interface 38 takes the form of a flat surface oriented along an XY plane. On the other hand, it comprises reinforcing ribs 40 integral with the upper face of the fixing plate 36 and the outer face 42 of the longitudinal portion 28, these ribs 40 being oriented in parallel planes YZ. In a preferred manner, it can be provided that the interface 38 lies approximately in the lateral continuity of a lower surface of the spar 20, as can be seen in FIG.
- one of the features of the invention lies in the fact that the outer face 42 of the longitudinal portion 28 is in contact with an inner face 44 of the panel lateral 22 being associated with it. Therefore, the longitudinal portion 28 is pinched between the side panel 22 and the flange 34 of the lower spar 20, these three directly superposed elements being assembled to each other, preferably by bolting.
- the transverse portion 30 To allow the transverse portion 30 to protrude laterally outwardly relative to the panel 22, the latter is provided with a recess 48 open downwardly and traversed by the transverse portion. In this configuration, at least a portion of the attachment plate 36 is located beyond the panel 22 in the Y direction, as is clearly visible in FIG. 3.
- FIG. 4 shows that the cutting of the notch 48 is in particular made so as to let through the ribs 40, which also pass through this notch 48 to protrude laterally outwards with respect to the panel 22.
- the lower spar 20 presents a constriction 50 in the direction Y, this constriction 50 being formed by two recesses 52 respectively serving to house the two side fittings 26 of the two half-rear fasteners. It is therefore the inner face 32 of the longitudinal portion 28 which is in contact with the recess 52 defined by the wing 34 of the lower spar, this wing portion therefore having a slight curvature towards the inside of the box.
- the geometry of the recess 52 is determined so that the longitudinal portion 28 housed therein has an outer face 42 substantially in the continuity of the outer face of the right portion of the wing of the spar 20, for the purpose to form, with these two outer faces, a flat bearing surface oriented substantially along an XZ plane for the panel 22.

- each rear half-attachment comprises the hinged shackle 60, the yoke 58 and the fitting 26, the two yokes 58 of the two half-fasteners being furthermore united within the same rear attachment body. 54, preferably made in one piece.
- the rear attachment 8 forms two half-fasteners each capable of ensuring the recovery of the forces exerted in the direction Z. In a preferred embodiment of the present invention, it is provided that the rear attachment 8 is also able to ensure the recovery of the forces exerted in the direction Y.
- the rear engine attachment 8 also comprises a first shear pin 66 oriented in the Z direction, this pin 66 being provided to ensure the recovery of efforts s exercising in a Y direction, and more particularly to allow the passage of these efforts between the rear attachment body 54 and the rigid structure 10 of the attachment pylon.
- the pin 66 has an upper end 68 (only visible in Figure 5) located at one of the transverse ribs 24 in the form of a frame, this end 68 also occupying a projecting position within this frame making it easily accessible.
- the pin 66 then extends downwardly through successively the lower part of the rib 24 concerned and the lower spar 20. It then comprises a lower end 70 projecting downwards relative to the spar 20 of the box, and being housed in an orifice 72 of the rear attachment body 54. It is therefore the contact between the surface of this end 70 and that of the orifice 72 which makes it possible to ensure the recovery of the forces in the direction Y.
- the orifice 72 has a generally oval shape substantially complementary to that of the shear pin 66, and takes the form of a blind hole made in the upper part of the fastening body 54.
- the rear engine attachment 8 further comprises a first auxiliary pin 78 aligned with the shear pin 66 in the direction of the pin X, therefore preferably in the X direction.
- the direction of the pin 74 could be different, while remaining preferentially in an XY plane, without departing from the scope of the invention.
- This pin 78 has a similar design to that of the pin 66 described above. Thus, it has an upper end 80 (only visible in FIG. 5) also located at the level of the transverse rib 24 above, this end 80 occupying a projecting position within the frame formed by this rib, which makes it easily accessible.
- the pin 78 then extends downwardly through successively the lower part of the rib 24 concerned and the lower spar 20. It then comprises a lower end 82 projecting downwards relative to the spar 20 of the box, and being housed in an orifice 86 of the rear attachment body 54.
- the orifice 86 has a generally oval shape substantially complementary to that of the annex pin 78, and takes the form of a blind hole made in the upper part of the attachment body 54.
- the rear fastener 8 is designed so that the pin 74 issuing from the central part of the body 54 then passes successively through a bore 84 formed in the lower end 82 of the pin 78, as well as a rear portion of the same body 54 until it opens out of it.
- a functional clearance between pin 74 and the bore 84 in order for the force path constituted by the elements 74 and 82 to be solely operative during a failure / rupture of the right rear half-attachment, a functional clearance between pin 74 and the bore 84.
- the rear attachment 8 comprises a mounting similar to that just described, but which is associated with the left rear half-attachment, in particular for the purpose of ensuring the safety function "Fail Safe" for the transmission of 'Efforts in the Z direction normally provided by this half-left rear fastener. Indeed, it is also provided a second shear pin 88 and a second auxiliary pin 90 respectively identical to the pins 66 and 78, these second pins 88, 90 being provided with lower ends 92, 94 housed in the body 54 and traversed by a second pin 96 at bores 98 and 100.
- the set pins / pin associated with the left rear half-attachment is the symmetrical relative to the plane P of the set pins / pin associated with the half-right rear attachment, the only difference between these two sets being the desired game between the second shear pin 88 and its associated orifice (not shown) formed in the rear attachment body.
- This game is again here provided so that the second pin 88 only allows to provide the function "Fail Safe" for the transmission of forces exerted in the direction Y, in case of failure occurring at the level of the first pawn of shear 66.
