Definitions
- the present invention relates to a device for passing servitudes for a turbomachine, this device being commonly called “kit engine” in the aeronautical field.
- An easement passage device or kit engine comprises two coaxial annular shrouds, respectively internal and external, between which radial arms extend, at least some of which are traversed by servitudes such as pipes or conduits carrying fluids and harnesses. electric.
- the arms generally have a torque master imposed by aerodynamic constraints related in particular to the expected performance of the engine.
- the easements that pass in an arm must be held inside the arm to prevent vibration in operation and they come into contact with each other.
- the easements are maintained inside the arm by supports which are independent of the arms and which enclose several servitudes by keeping them at a distance from one another.
- the engine kit is equipped with the servitudes and the support brackets are mounted on the servitudes and on the structural arms of the intermediate casing before mounting the arm of the engine kit on the intermediate casing.
- some engines may comprise a service crossing arm having a relatively low torque-master, which prevents the use of the aforementioned technology to maintain servitudes inside the arm. Indeed, during assembly of the engine kit arm on the intermediate casing equipped with easements, the arm may come into contact with the supports or easements, which may damage the arm.
- the present invention aims to remedy this problem simply, efficiently and economically.
- the invention proposes a device for the passage of servitudes for a turbomachine, comprising two coaxial annular shrouds, respectively internal and external, between which radial arms extend, at least one of which serves as a passage for servitudes, and means for maintaining servitudes housed inside the arm, characterized in that the arm comprises on one of these walls a window closable by an attached cover and fixed on the arm, and in that the holding means comprise at least a first member fixed on the inner surface of the arm and at least a second member fixed on the inner surface of the cover, the attachment of the cover on the arm causing the clamping and maintenance of servitudes between the first and second members.
- the present invention thus proposes a new technology for maintaining the servitudes inside a service crossing arm, this technology avoiding any impact between the arm and the means for maintaining the servitudes during the mounting of the arm because these means are secured. of the arm and are mounted on the easements at the same time as the arm.
- the arm can be a kit engine arm or another arm of the turbomachine such as an arm of the exhaust casing.
- the window is formed on a side wall of the arm and the first holding member is fixed on the inner surface of the other side wall of the arm, substantially facing the window.
- the window may be located on a middle portion or substantially mid-height of the arm.
- the window may have a parallelepipedal shape and be delimited by peripheral edges of the arm, respectively radially inner, radially outer, upstream and downstream.
- the hood can be attached to the arm by any suitable fastening means such as screws, rivets, etc.
- the hood is preferably of the removable type.
- each servitude holding member comprises additional fingerprints of parts of the servitudes, for the purpose of wedging them.
- Each member may comprise a block of material in which the aforementioned impressions are formed.
- the present invention also relates to a service crossing arm for a device as described above, characterized in that it comprises on one of these walls a window closable by an attached cover and fixed on the arm, at least a first servitude-holding member fixed on the inner surface of the arm and at least one second servitude-holding member fixed on the inner surface of the cover, the fixing of the cover on the arm being intended to cause the tightening and the maintenance of the servitudes between the first and second organs.
- the arm is substantially dihedral and comprises two side walls connected by their downstream edges.
- the window may be formed on the medial portion of one of the side walls and be spaced from the upstream, downstream and radially inner and outer edges of this wall.
- the present invention also relates to a turbomachine, such as a turbojet or an airplane turboprop, characterized in that it comprises at least one device of the aforementioned type.
- the present invention finally relates to a method of mounting a device as described above, characterized in that it comprises the steps of:
- FIG. 1 is a very schematic view of an easement passage device for a turbomachine, seen from the front;
- - Figure 2 is a schematic perspective view of the easements and a passage arm of these easements of an easement passage device, according to the prior art to the invention
- - Figure 3 is a schematic perspective view of the easements and a passage arm of these easements of an easement passage device according to the invention
- FIG. 4 is a schematic perspective view of a maintenance member of the servitudes inside the arm according to the invention.
- FIG. 5 is a schematic perspective view of the arm of Figure 3, crossed by servitudes;
- FIG. 6 is a schematic perspective view of the arm of Figure 3, the side window has been closed by a cover.
- FIG. 1 a very schematic view of a device 10 for the passage of servitudes also called “kit engine” of a turbomachine, such as a turbojet or a turboprop aircraft, this kit engine Typically having two coaxial annular ferrules, respectively internal 12 and outer 14, between which radial arms 16, 16 'extend.
- this engine kit 10 is mounted between the low pressure and high pressure compressors of the engine, the ferrules 12, 14 delimiting the annular duct 18 for passage of the secondary flow.
- the engine kit 10 comprises four arms 16, 16 'which are located respectively at 3h, 6h, 9h and 12h, by analogy with the dial of a clock.
- the arms 16, 16 ' have profiles and transverse dimensions which depend in particular on their function and aerodynamic constraints related in particular to the expected performance of the engine.
- the engine kit 10 here comprises an arm 16 to 12h relatively thick transversely, that is to say having a relatively large master torque, and three arms 16 'to 3h, 6h and 9h which are relatively thin transversely, that is to say to say that they have a relatively weak master couple.
- FIG. 2 represents the prior art technology for maintaining the servitudes inside a service crossing arm, when this arm has a sufficient torque master, as is the case of the arm 16 of FIG. 1.
- Easements 20 may be conduits, ducts, electrical harnesses, etc. They extend between the inner and outer shells 12 and 14, substantially radially with respect to the longitudinal axis of the engine kit. They are maintained rigidly at a distance from each other by means of two supports 22, each support enclosing the servitudes (two in number in the example shown).
- the arm 1 6 has a dihedral shape and comprises two substantially parallelepipedal side walls 24 whose downstream radial edges 26 are interconnected.
- the upstream radial edges 28 are at a transverse or circumferential distance from each other and define an upstream opening of the arm through which the servitudes 20 are engaged in the arm.
- the arm 16 is mounted between the shells 1 2, 14 of the engine kit by moving it in translation from downstream in a direction parallel to the longitudinal axis of the engine kit (arrow 30), until the side walls 24 of the arm are arranged on either side of the easements 20.
- the master torque of the arm 1 6 is such that the side walls 24 of the arm are sufficiently spaced apart from one another so that the supports 22 maintenance easements do not come into contact with these walls when mounting the arm.
- the invention makes it possible to remedy this problem by means of maintaining the servitudes which are integral with the passage arm of these servitudes and which are mounted on the servitudes at the same time as the arm.
- FIGS. 3 to 6 show an embodiment of the invention in which the arm 1 6 'differs from that 1 6 previously described in particular in that it comprises a window 32 on one of these side walls 24.
- the window is here formed in a median portion of the wall 24, away from the downstream 26 and upstream radial edges 28 of the arm.
- This window 32 has a substantially parallelepipedal shape and comprises radially outer peripheral edges 34, radially inner 36, downstream 38 and upstream 40.
- This window 32 is intended to be closed by a cover 42 which bears on a peripheral rim 44 extending around the entire periphery of the window (FIG. 6).
- the cover 42 has a parallelepipedal shape and includes orifices 46 aligned with orifices 48 of the flange 44 for the passage of screws or rivets for fixing the cover to the arm.
- the outer surface of the cover 42 is aligned with the outer surface of the side wall 24 on which is fixed this cover.
- the inner surface of the cover 42 and the inner surface 50 of the side wall 24 opposite the cover each carries a member 52, 54 for holding the servitudes 20 inside the arm, these members 52, 54 cooperating with each other to mount the cover to immobilize the easements between them.
- a first holding member 52 is fixed on the inner surface of the side wall 24, substantially facing the window 32 of the other side wall 24 ( Figure 3).
- the second holding member 54 is fixed on the inner surface of the cover and is intended to be located opposite the first means 52 when the cover is mounted on the arm ( Figure 6).
- Fixing the members 52, 54 on the arm 1 6 'and the cover 42 can be achieved by gluing, welding, soldering, etc.
- the holding members 52, 54 may be identical and each formed of a block of material, for example metal, plastic, elastomer, etc., a face 56 of which is intended to be applied against the aforementioned internal surface and whose opposite face 58 comprises cavities 60 of housing and wedging of the servitudes 20.
- the arm 1 6 ' is traversed by five servitudes 20 and the block of material of each member 52, 54 comprises on its face 58 five cavities 60, each cavity having an elongate groove and rectilinear, which has in section a semi-circular shape whose diameter is substantially equal to or slightly greater than that of the corresponding servitude.
- the grooves of the cavities 60 are parallel and at a distance from one another to keep the servitudes at a distance.
- the block of the member 52 has an elongated shape and an orientation that is substantially parallel to the longitudinal axis of the engine kit and therefore extends substantially perpendicular to the servitudes 20.
- the middle portions 62 of the servitudes 20 are intended to engage in the fingerprints 60 of the block of the member 52.
- the median portion 62 of each servitude carries a cylindrical ring 64 intended to protect and maintain the servitude when mounting the hood .
- the easements 20 are intended to engage in the fingerprints 60 of the block of the member 54 carried by the cover.
- Fixation of the hood 42 to the arm causes the clamping of the middle portions 62 of the servitudes between the blocks of the members 52, 54, that is to say in the mounting position shown in Figure 6, the holding members 52, 54 are designed in this mounting position, the faces 58 of the blocks of the members 52, 54 can bear against each other or at a distance from one another. other.
- the mounting of the arm 16 'in a kit engine 10 equipped with servitudes will now be described.
- the arm 16 ' is positioned downstream of the easements, as shown in Figure 3 and is moved upstream by translation along the longitudinal axis of the engine kit (arrow 30). It may be necessary to move the middle portions 62 of the eases 20 (which are relatively flexible) to allow the passage of the block of the member 52 on one side of the easements and to engage these median parts in the footprints 60 of this block.
- the cover 42 is then attached and fixed on the arm, which causes the clamping and tightening. immobilization of the servitudes between the blocks of the members 52, 54.
