Definitions
- a manual locking system comprising a gripping system of the mobile structure by the handle at the end of maneuvering the structure. This technique avoids a long and tedious assembly / disassembly with a system of maintenance by bolting.
- a system is not suitable for a motorized drive of the mobile structure since the manual drive system and the lock are coupled. It will also be noted that the adjustment of the pretension of the locks is also long and tedious. Therefore, there is a need for a locking system of such a mobile structure to solve all or part of these problems.
- the present invention relates to a turbojet engine nacelle comprising an air intake structure adapted to channel a flow of air to a fan of the turbojet engine and a median structure intended to surround said fan and to which is attached the air intake structure to provide aerodynamic continuity
- the air inlet structure comprising, on the one hand, at least one inner panel attached to the middle structure and forming therewith a fixed structure of the nacelle, and secondly, at least one longitudinal outer panel removably attached to the fixed structure and incorporating an air inlet lip so as to form a removable air inlet structure, characterized in that that the removable air inlet structure is equipped with peripheral locking means comprising at least one electric lock each adapted to cooperate with a complementary retaining means.
- electrical locking means also avoids the establishment of manual locking and unlocking means (handles, cables) generating aerodynamic accidents while also avoiding the use of bolting systems whose implementation in place and unlocking are long and tedious.
- the electric lock comprises a hook capable of cooperating with a corresponding stirrup.
- the removable air intake structure is equipped with a rail / slide type guide system mounted on a part of the fixed structure.
- the electric lock or locks are each arranged substantially at a guide rail.
- the locking means are preferably located at the level of the zones of effort and therefore allow a better recovery of the latter.
- control member is a handle, preferably retractable, adapted to allow the driving of the moving air inlet structure.
- the adjustment of the complementary retaining means is effected by means of an endless screw adapted to cooperate with a threaded zone of said retaining means so as to allow a translation of the retaining means in the direction of detention.
- Figure 2 is a partial schematic representation of the air intake structure of Figure 1, the air inlet structure being in the open position.
- Figure 3 is an enlarged partial schematic representation of a first embodiment of a locking means equipping the nacelle of Figures 1 and 2.
- FIG. 8 represents a second embodiment of the pretensioning of a locking means equipping a nacelle according to the invention.
- the lip 2a is integrated with the outer panel 20 so as to form a single piece that can be dismantled, the inner panel 21 being attached upstream of a casing of the blower. belonging to the median section of the nacelle via fastening flanges 3, integral respectively with the downstream structure 2b and the housing.
- outer panel 20 may also comprise all or part of an outer panel of the median structure.
- each flange 3 also supports a radial peripheral wall 5.
- This partition 5 may carry centering and secondary centering extending perpendicular to said partition 5 upstream of the nacelle.
- the air intake structure 2 can extend axially through its outer panel 20 beyond a fastening flange of the inner panel 21 to the fixed structure of the platform 1 to neighboring an external structure of a thrust reversal structure belonging to the downstream section of the nacelle and possibly covering the covers.
- a lock system can then be provided to maintain the air intake structure on the partition 5 integral with the housing structure or an upstream structure of the downstream structure.
- the removable structure may be mounted, for example, on a slide rail system 6 / slide 7 comprising a plurality of rails 6 / slides 7 distributed on the periphery of the air inlet structure 2.
- the maintenance of the removable structure is effected by locking means comprising at least one electric lock 10 of the hook type each adapted to cooperate with a complementary retaining means 11 caliper type.
- the complementary retaining means 11 are attached to the fixed structure while the electric locks 10 are attached to the removable structure.
- the locking means may each be equipped with at least one stiffener supporting the lock.
- the stiffeners are associated with the slides 7, but this is not strictly necessary.
- Figures 1 and 2 show the removable structure respectively in closed and open position.
- the locking and unlocking controls of the electrical locking means are grouped at the level of an external control means of the nacelle and / or at the level of the cockpit of the aircraft.
- the retaining means 11, stirrup type, are positioned on the fixed structure of the nacelle in a zone ensuring the best structural rigidity to avoid any deflection of this interface.
- Each lock advantageously has a screw 12 for driving the hook protruding from the lock 10 towards the outside of the nacelle.
- a corresponding flap 13 may be provided in the outer panel 20 allowing access to one end of the screw 12.
- the tool may advantageously be guided by a fitting 14 fixed to the inside of the outer panel 20 at the level of the hatch 13.
- the manual drive can also be performed by means of a dedicated component of the type MDU 30 (Manual Drive Unit) linked to the driving motor of the electric lock 10.
- MDU 30 Manual Drive Unit
- a particular plug 15 having an appendage 15a adapted to cooperate with the screw 12 so as to block it.
- Such a cap will then mechanically inhibit the electric lock.
- This configuration is shown in Figure 6.
- the cap 15 may have an aerodynamic appendage visible from the outside of the nacelle to remind its presence.
- At least a portion of the locking means 10 are each associated with means for signaling their state of locking or unlocking and whose information can be raised to the cockpit or a control unit, for example.
- This signaling means may be in the form of a proximity detector disposed on the stirrup 11 facing one end of the hook 10 so as to obtain an "all or nothing" type signal and to ensure that the hook is honest and actually in place to fulfill its function.
- the signaling means is preferably placed on a fixed element (caliper, for example) in order to reduce the disconnection interfaces, which would reduce the reliability of the system.
- the locking means equipping a nacelle according to the invention also have pre-tensioning adjustment means.
- the pre-tensioning adjustment in mechanical locking systems is generally performed by positioning a load cell at the end of the handle, hook in contact on the caliper, then pulling on the load cell and verifying the traction value obtained. . When this value is not adequate, access to the caliper fixing system and adjust it to the axial position and then carry out the check again until the desired value is obtained.
- the pre-tension value can be controlled in various ways, such as by the voltage given to the motor during locking, by means of a manual drive system. using a torque wrench, a voltage sensor installed on one of the mechanical parts in contact and voltage such as the hook or the caliper, or by a torque limiter installed on one of the mechanical parts in contact and tension like the hook or the stirrup. These various means are used to control and monitor the voltage.
- the present locking means are also equipped with adjustment means for adjusting the pre-tension value when the removable structure is in the closed position.
- Figure 7 shows a first pretension adjusting means.
- a fitting 40 is disposed on the removable outer structure vis-à-vis the element to be adjusted (yoke 11 here) when said removable structure is in the closed position.
- An opening 41 is made in the fitting so as to allow the passage of an adjusting tool such as a key.
- the stirrup 11 is mounted to move in translation in the locking direction and has a slot 42 capable of receiving a heel 43 having a first end of small thickness and a second end of greater thickness.
- the access fitting 40 may be replaced by a hatch, for example, or any other means allowing access to the adjusting screw.
- Figure 8 shows a second pretension adjusting means.
- an access hatch 50 is formed in the outer wall 20 of the removable structure vis-à-vis the element to be adjusted (bracket 11 here) when said removable structure is in the closed position.
- a fitting access as described above is obviously possible.
- the pre-tension adjusting means comprises a worm 51 cooperating with a threaded end 52 of the caliper, so as to allow axial displacement of the latter when the worm 51 is rotated.
- a locking device 53 of the worm is added so as to ensure the maintenance of the adjustment over time.
- a specific abutment for reducing friction can be inserted between the fixed support and the adjustment nut.
- a torque limiter can also be added at the end of the auger, thus ensuring control of the tension in the caliper without the need to use a torque wrench.
- this system can be motorized to ensure a permanent identical voltage by permanent voltage control.
- the lock may be associated with a proximity detection of the removable upstream structure close to its closed position, said proximity detection being able to authorize the implementation of the lock. This ensures a good distance for gripping the stirrup by the hook. Proximity detection may be used also to trigger an automatic lock according to this approach of the removable structure.
