Definitions
- the present invention relates to the field of aircraft wings, of the type comprising a central supporting wing body which remains fixed and which carries one or more movable leading edge flaps, also called "slats".
- Each of the two wings of the wing is generally equipped with high-lift movable flaps, mounted at the leading edge of the wing. Flaps are deployed for landing and takeoff phases to increase lift at low or medium speed. In high-speed cruise flight, the movable flaps are retracted to limit the resistance to the forward movement of the aircraft.
- Fixed leading edges and movable flaps are made up of a multitude of parts, including for example ribs, coverings, electrical systems as well as guide rails, hinges and pivoting arms, to enable imposing to the moving part the desired movement.
- these different parts are individually integrated into the wing by operations, among other things, drilling and riveting to constitute the fixed leading edge and bolting and adjustment to mount the movable shutters.
- drilling operations are likely to deposit metal shavings in removable parts of the wing which therefore run the risk of being damaged during their movement. Another risk includes damage to electrical cables during drilling operations.
- leading edge module comprising the fixed leading edge, the movable flap with its removable parts, which are mount on the wing without the need to carry out drilling operations on the assembly line.
- an adjustable guide ring comprising a first ring with a first eccentric opening and a second ring with a second eccentric opening.
- the first ring is housed in the second opening of the second ring.
- An eccentricity of the first opening within the first ring may correspond to an eccentricity of the second opening within the second ring and a first fixing means for fixing a relative position between the first and the second ring may be provided.
- the first ring and the second ring may include an indicator to indicate an orientation of the eccentricity of the first ring within the second ring.
- the indicator comprises a dial on the first and/or the second ring, the dial comprising a symbol to indicate an orientation of the eccentricity of the first ring within the second ring.
- the ring may comprise a second fixing means for fixing a rotary position of the first and/or the second ring relative to an environment receiving the second ring, the second fixing means being configured to be able to be fixed to the first and/or or the second ring has one of a plurality of rotatable positions.
- the second fixing means may comprise a second dial to indicate said rotary position.
- the second fixing means may be a plate comprising a first device for being fixed to the environment and a crenellated opening for receiving the first ring.
- the castellated opening may include the second dial, the first ring comprising a castellated edge configured to be received in said castellated opening.
- a procedure for adjusting a ring eccentricity described previously may include the following steps:
- the method comprises the step of providing a position to be adjusted on said dial to establish the rotary position of the first ring relative to the determined second ring.
- the process can comprise the following steps:
- a procedure for attaching a leading edge module to a wing box may include the following steps:
- FIG. 1 shows a first part to be fixed and a second part to be fixed, the two parts being intended to be fixed relative to each other,
- FIG. 2 shows the mechanism of an adjustable guide ring or in other words, of a double eccentric ring
- FIG. 3 shows the adjustable guide ring mounted in an environment receiving the ring
- FIG. 4 shows a sectional view of the adjustable guide ring mounted in an environment receiving the ring
- FIG. 6 shows a fixing nut with a tab washer or lock washer
- FIG. 7 shows a leading edge module and a wing box.
- Figure 1 shows a first part to be fixed (190) and a second part to be fixed (200), the two parts being intended to be fixed relative to each other.
- the first part to be attached may be a leading edge module (190) and the second part to be attached may be a wing box (200). Said attachment thus mounts the leading edge module to the wing box.
- the first part and the second part are fixed relative to each other by a connecting bolt (350).
- the right side of Figure 1 shows a section along line AA shown on the left side, but without the connecting bolt.
- the connection bolt (350) is received by a first hole (210) in the first part and a second hole (220) in the second part, as shown in Figure 1, left part.
- the first and second breakthrough can be manufactured by reaming.
- the right part of Figure 1 shows the first part and the second part held at a desired relative position, before insertion of the bolt. It is observed that a diameter of the first breakthrough is less than a diameter of the second breakthrough. It is also observed that a center of the first breakthrough (230) is displaced relative to a center of the second breakthrough (240). Said displacement can be characterized by a vector, indicated by an arrow between said centers in Figure 1, right part.
- Said vector has a length corresponding to a distance (250) between the centers of the breakthroughs.
- An orientation of the vector can be described by an angle (280) relative to a straight line passing through the center of the second breakthrough (240) and a fixing point (290) on the first or on the second part, as will be detailed by the following.
- said fixing point is located on the part receiving the adjustable ring or double eccentric ring. Said angle thus fixes a direction of the distance between centers relative to the fixing point on the first or on the second part.
- said attachment point is provided on the second part.
- the relative position of the first breakthrough and the second breakthrough is described by a distance between centers of the breakthroughs and by a direction of the distance.
- the direction of the distance is described by said angle (280).
- the connecting bolt (350) passes through the first hole and the second hole to secure the two parts together, as shown in the left part of Figure 1.
- one diameter of the bolt is smaller than one of the two holes.
- the diameter of the bolt must be smaller than the diameter of the second hole in the second part in the example shown.
- An eccentric guide ring includes an eccentrically placed opening. That is, a center of the opening of the ring is displaced relative to the center of an outer circumference of the ring. The eccentricity and the orientation of the eccentricity of the ring are described by a vector.
- An “eccentricity” of the ring is the size or length of said displacement of centers or the distance of this displacement of centers. In other words, it is the length of the link vector between the two centers.
- An “orientation” of this eccentricity is the direction of this movement relative to a straight line passing through the center of the outer circumference of the ring. Said straight line remains fixed relative to said outer circumference of the ring. In other words, it is the direction of the vector relative to said straight line.
- the eccentricity of the ring to be used must correspond to the distance between centers (250) of the holes in the parts.
- the ring to use will be an adjustable ring or double eccentric ring.
- the ring must be rotated relative to an environment (340) receiving the ring to align the orientation of the eccentricity of the ring with the direction of the distance between the centers (280) of the bores in the two parts to be to stare.
- the vector of the distance between centers must be aligned with the vector of the eccentricity of the ring.
- FIG 2 shows an adjustable guide ring (10).
- the adjustable guide ring includes a first ring (20) with a first eccentric opening (30) and a second ring (40) with a second eccentric opening (50).
- the first and second ring each have an outer circular shape with an outer circumference and a circular opening.
- the center of the circular opening is displaced relative to the center of the outer circular shape of the ring.
- the first ring has a first eccentricity (170) and the second ring has a second eccentricity (180).
- the first ring is housed in the second opening of the second ring.
- the adjustable guide ring thus has the outer circular shape of the second ring and the circular opening of the first ring.
- an eccentricity of the adjustable guide ring (270) corresponds to the displacement of the center of the first opening relative to the center of the outer circular shape of the second ring.
- the eccentricity of the adjustable guide ring (270) is the magnitude of the vector sum of the vector characterizing the first eccentricity of the first ring (170) and the vector characterizing the second eccentricity of the second ring (180).
- the eccentricity of the adjustable guide ring (270) can thus be adjusted by rotating the first ring inside the second ring.
- a rotary position (260) of the first ring relative to the second ring thus determines a distance or eccentricity of the adjustable guide ring.
- the eccentricity of the adjustable guide ring By changing the eccentricity of the adjustable guide ring, its eccentricity changes.
- the orientation of the eccentricity of the adjustable guide ring can be described relative to the straight line passing through the center of the circumference of the second ring and the center of the circumference of the first ring.
- the eccentricity of the adjustable ring is a function of the orientation of the eccentricity.
- the eccentricity of the adjustable guide ring can be adjusted to correspond to said distance by choosing the corresponding rotary position (260 ) between the first and second ring.
- Said rotary position or in other words, a rotary position between the two rings can be described by the angle between the vectors characterizing the first eccentricity of the first ring and the second eccentricity of the second ring, as indicated in Figure 2.
- first fixing means (60).
- Said first fixing means is thus configured to fix the rotary position chosen between the first and the second ring. It thus fixes the adjusted eccentricity.
- Figure 4 shows an example of the first fixing means.
- the first ring has a crenellated edge (160).
- the second ring also has a crenellated edge (165).
- the first fixing means comprises a plate with an opening having a crenellated surface inside it. The crenellated surface of the opening of the first fixing means is fixed at the same time on the crenellated edge of the first and the second ring, as shown in Figure 4.
- neither the first ring nor the second ring can rotate relative to the first fixing means. A rotary position of the first ring relative to the second ring is thus fixed.
- the eccentricity of the first opening within the first ring corresponds to the eccentricity of the second opening within the second ring.
- the eccentricity of the adjustable guide ring can be adjusted between a value of zero and a value of twice the eccentricity of the first opening within the first ring.
- the eccentricity of the adjustable guide ring can be adjusted to correspond to the distance between centers (250) of the first and second bore (230, 240). It is therefore advantageous to provide an indicator (70) to indicate an orientation of the eccentricity of the first ring within the second ring.
- the indicator (70) makes visible the orientation of the eccentricity of the first ring relative to the orientation of the eccentricity of the second ring.
- the indicator makes visible the rotary position (260) between the orientation of the eccentricity of the first and the second ring so as to be able to make visible the eccentricity of the adjustable guide ring.
- Said indicator (70) is included by the first and the second ring.
- the direction of the eccentricity of the adjustable ring can, as described previously, be defined by the angle between two straight lines: A first straight line passing through the centers of the outer circumferences of the first and second ring. A second straight line passing through the center of the outer circumference of the second ring and the center of the opening of the first ring.
- Figure 3 shows an example of indicator (70).
- the indicator includes a dial (80) on the first and/or second ring.
- the indicator includes a dial on the second ring.
- a line or arrow on the first ring is positioned opposite a symbol on the dial. The position indicated by the arrow on the dial can thus be translated into the eccentricity of the adjustable ring.
- the orientation of the eccentricity of the adjustable ring (270) must be oriented by relative to the two parts to correspond to the direction of the distance between centers (250) of the breakthroughs (210, 220). Preferably, it should be fixed in this position.
- the vector characterizing the distance between centers (250) shown in Figure 1, right must be aligned with the vector characterizing the orientation of the eccentricity (270) of the adjustable ring, shown in Figure 2.
- adjustable ring may for this purpose comprise a second fixing means (90) for fixing a rotary position of the first and/or the second ring relative to an environment (340) receiving the second ring.
- the second fixing means (90) fixes the first and the second ring relative to the second part.
- the second part receives the adjustable guide ring.
- the second attachment means is configured to be attachable to the first and/or second ring at one of a plurality of rotatable positions (100).
- the second fixing means also comprises a second dial (110) to indicate said rotary position.
- the second dial makes it possible to orient the second fixing means relative to the adjustable guide ring. This orientation is chosen to align the eccentricity of the ring with the distance between centers (250) shown in Figure 1, once the second fixing means is attached to the environment.
- Figures 3, 4 and 5 show the second fixing means implemented by a plate (120).
- this plate is at the same time the first means of fixation.
- the first ring and the second ring each include a crenellated edge.
- the plate includes a castellated opening which attaches to the two castellated edges of the first and second rings.
- a rotary position between the first and second ring is thus fixed.
- an orientation of the eccentricity of the adjustable ring (270) relative to the first and second parts is also fixed by attaching the plate to the first and/or second part.
- it can be a male/female yoke.
- the serrated surface may include 36 teeth, corresponding to an adjustment in 10° steps.
- the tightening or the teeth of the crenellated opening of the plate are offset relative to the fixing device (130) on the plate.
- a tip of a tooth of the tightening is not on a straight line passing through the fixing device and the center of the crenellated opening of the plate, but is offset relative to said straight line.
- an offset angle of 2.5° can be chosen.
- an adjustment step of 5° can be obtained by turning the plate, as shown in Figure 5.
- the plate comprises a first device (130) for being fixed to the environment receiving the second ring, for example to the first and/or the second part.
- said first device is an opening in the plate.
- the orientation of this opening in the plate with respect to the adjustable guide ring determines the orientation of the eccentricity of the adjustable ring with respect to the first and the second part and thus also with respect to the direction of the distance between centers (250), shown in Figure 1.
- the plate is fixed with the first device (130) at the attachment point (290) on the first or second part, shown in Figure 1, right.
- Figures 3 and 4 show that the crenellated opening of the plate comprises the second dial (150) described above.
- the dial includes symbolism to be able to differentiate between different positions.
- the first ring includes an indicator, for example an arrow, on its serrated edge which points to a symbolic on the dial. Thus a rotary position between the plate and the adjustable guide ring is indicated on said dial.
- the adjustable ring may be secured to the ring receiving environment by a nut (360), secured by a tab washer (370), shown in Figure 6.
- Figure 6 shows the opposite side of the environment receiving the adjustable ring, shown in Figure 3.
- the nut is fixed on a thread on the first ring.
- the first ring places with its crenellated edge on the first ring.
- the tab washer secures the nut against unscrewing.
- a measuring and adjusting device (hereinafter referred to as a “device”) can be used to configure the adjustable guide ring together with its plate for use.
- the measuring device determines the distance between centers of the breakthroughs (figure 1) and the direction of said distance relative to the position of the fixing point (290) on the first or second part. Then, the measuring device provides the value to be adjusted on the dial of the first or second ring (80). In other words, a value on the dial (80) is provided which must be placed opposite the indicator (70), see Figure 3. In the example shown in Figures 1 and 3, the measuring device would indicate adjust position “A” on the dial. The arrow on the first ring is thus turned to be placed opposite the symbol “A” on the dial of the second ring.
- the measuring device provides a position to adjust on the second dial.
- a second indicator on the edge of the first ring is placed opposite a value from the second dial.
- the measuring device would indicate to adjust position “2” on the second dial.
- the plate is thus fixed with its crenellated opening on the crenellated edge of the first and second ring so that the arrow on the crenellated edge of the first ring points to position “2” on the second dial.
- the adjustable ring with its plate can then be attached to the second part, shown in Figure 1, right.
- the first fixing device (130) on the plate is fixed at the location of the fixing point (290) on the second part while the adjustable ring is inserted into the second hole (220) in the second part.
- the first opening (30) of the first ring is aligned with the first hole in the first part and the connecting bolt can be installed.
- the values provided by the measuring device are determined so that the eccentricity of the adjustable ring and the direction of the eccentricity correspond to the distance between centers (250) when the plate fixing device (130) is fixed on the fixing point (290), see figures 1 and 3.
- Said measuring and adjustment device may be a mechanical device. It is also possible that said measurement and adjustment is an optical device.
- the device may include a camera or three-dimensional scanner to acquire a representation of the first breakthrough, the second breakthrough, and the attachment point (290) when the first and second parts are held in a desired relative position. Knowing the eccentricity of the first and second rings of the adjustable ring and a positioning of the dial and the second dial, the device can then provide the values to be adjusted on the two dials to configure the adjustable ring for use with the first and second piece.
- the device can perform a three-dimensional digitization of a first part representative of the wing box to obtain a first digital model, and to perform a three-dimensional digitization of a second part representative of the leading edge module in order to obtain a second digital model.
- the first part includes a first reference region and the first breakthrough
- the second part includes a second reference region and the second breakthrough.
- the attachment point (290) is located on the first or second representative part.
- a relative position of the first reference region to the second reference region is defined to locate the wing box and the leading edge module at a desired position. Consequently, the relative position of the first breakthrough compared to the second breakthrough and the positioning of the bridge fixation are known.
- the device then provides the values to be adjusted on the dials of the adjustable ring (10) to establish the connection.
- the procedure for adjusting the eccentricity of the adjustable ring will be described in more detail.
- the procedure can be carried out on a computer. It can also be implemented by a mechanical device. Subsequently, only the expression “device” will be used for the tool implementing the process.
- the eccentricity (170) of the first ring and the eccentricity (180) of the second ring are supplied to the adjustment device. It is also possible that said values are measured by the device. As described before, the eccentricity is the distance, for example in millimeters, between the center of the opening of the ring and the center of the outer circumference of the ring.
- the eccentricity of the adjustable ring can be adjusted within a range of values, said range extending between the sum of the two eccentricities up to the difference between the two eccentricities of the two rings forming the adjustable ring.
- the device receives or measures a distance (250) between centers of a first circular breakthrough (210) in a first part (190) and a second circular breakthrough (220) in a second part (200). , when said parts are positioned at a desired relative position, as shown in Figure 1.
- the device determines a rotary position (260) of the first ring relative to the second ring so that the eccentricity (270) of the adjustable guide ring corresponds to said distance between centers.
- Said rotary position of the first ring inside the second ring can for example be determined in relation to a maximum position.
- Said maximum position is that where the adjustable guide ring has maximum eccentricity. In other words, by the maximum position it is the rotary position in which the two eccentricities of the first and the second ring add up.
- the rotary position relative to this maximum position is indicated in Figure 2 by the reference
- the first and second ring may include an indicator or dial (70, 80).
- the device can directly provide a position to be adjusted on said dial to establish the rotary position of the first ring relative to the second ring.
- the device would indicate “A”.
- a user can then change the relative position of the first and second ring until the arrow on the first ring points to "A" of the dial on the second ring.
- the device can also provide the information necessary to install the second fixing means and thus orient the adjustable guide ring relative to the environment receiving the ring. This step takes place after determining the relative rotating position of the first and second eccentric ring.
- the device receives or determines a direction (280) of the distance between centers relative to a fixing point (290) of the second fixing means on the first or second part. More precisely, the device receives or measures an angle (280) between a first straight line passing through the centers (230, 240) of the openings in the two parts (190, 200) to be fixed and a second straight line passing through the center of the opening receiving the adjustable ring (240) and the fixing point (290) used to fix the second fixing means, as shown in Figure 1, right part.
- the device determines and provides a rotary position (300) of the second fixing means relative to the first and/or second ring to orient the eccentricity of the guide ring in the direction determined when the second fixing means is fixed at the attachment point.
- the rotatable position provided allows a user to attach the plate to one of several possible positions on the adjustable guide ring.
- the plate is fixed with the opening (130) on the fixing point (290). Consequently, the orientation (270) of the eccentricity of the adjustable ring is aligned with the direction (250) of the distance between centers, see Figures 1, 3.
- the device can provide a position to be adjusted (310) on the second dial to establish said rotary position of the second fixing means relative to the first and/or the second ring.
- the device would provide “2” as position to be adjusted. A user can thus position the plate to put the “2” symbol on the second dial at the position of the arrow on the first ring.
- the adjustable guide ring can advantageously be used to attach a leading edge module (320) to a wing box (330), shown in Figure 7.
- the first part to be fixed may be the leading edge module and the second part to be fixed may be the wing box.
- the leading edge module is moved closer to the wing box to hold both at a desired position.
- the adjustable guide ring is configured to be able to fix the two parts by a connecting bolt passing through the first hole (210) in the leading edge module and the second hole in the wing box.
