Description

Technical Field

[0001] The invention relates to a wing for an aircraft, a method for connecting a connection assembly to a wing for an aircraft, and an aircraft comprising a wing for an aircraft. Background Art

[0002] The described wing for aircraft comprises main wing and high-lift assembly, high-lift assembly comprises high-lift body and connecting assembly, connecting assembly is connected to the main wing in a movably manner with the high-lift body, makes the high-lift body can move (for example, can move with respect to the main wing) between retracted position and at least one extended position.In order to make the high-lift body can move between extended position and retracted position, the high-lift body can comprise the slat track and the roller bearing that the high-lift body is connected to the main wing in a movably manner. The slat track can comprise a slat track axis, and this slat track axis extends along the length of the slat track, makes the slat track can move via roller bearing along the slat track axis. The high-lift body can be or comprise the leading edge slat or the trailing edge flap of the wing for aircraft.

[0003] The connector of the connection assembly is mounted to the main wing via a primary mounting profile and a secondary mounting profile. The primary connector can be configured to engage the primary mounting profile, and the secondary connector is configured to engage the secondary mounting profile.

[0004] Wings for aircraft typically include a connection assembly that movably connects a high-lift body to the main wing, for example, to allow the high-lift body to move between an extended position and a retracted position. The connection assembly in an aircraft wing may be supported by the aircraft's wing box and connected to the wing box via a joint. The wing box provides structural support for the aircraft wing and typically includes or defines a rib structure at the front leading edge of the wing external to the wing box itself. This rib structure may be used to carry leading edge devices, such as slats, which may be operated and supported via the connection assembly.

[0005] The connection assembly can typically be assembled with a wing box for an aircraft wing. During assembly, the connection assembly is connected to the wing box via a joint that may have tolerances and is configured to ensure the desired alignment of the wing box and the connection assembly. Alignment between the wing box and the connection assembly is important because it also determines the orientation of the high-lift body relative to the main wing. Therefore, mounting the connection assembly to the main wing is a task that requires high precision. Installation of the connection assembly can be completed during the assembly of the wing box, meaning that the wing box and the connection assembly can be assembled together to set the desired orientation of the connection assembly relative to the wing box.

[0006] It is desirable to modularize the process of constructing an aircraft, for example to increase efficiency in the process of constructing an aircraft and / or to automate some of the steps involved in the construction of an aircraft. Modularity may also have the advantage of making the repair and replacement of components easier, as individual components of the aircraft (e.g., modules) can be removed from the aircraft and replaced with identical modules without requiring any replacement work, and allowing smaller modules to be assembled quickly and easily by a single worker or a small number of workers. This would then allow the component that needs repair to be repaired on the ground without the rest of the aircraft having to remain on the ground with the component, which greatly reduces the time the aircraft is on the ground. However, in the case of the connecting assembly, the high precision required means that separating the construction of the wing box from the placement of the connecting assembly into discrete steps would make sufficiently accurate placement of the connecting assembly impossible, as the connecting assembly would have to be attached to a previously constructed wing box, whereby there would no longer be the freedom to adjust the relative positions of certain of its components. Summary of the Invention

[0007] It is therefore an object of the present invention to provide a wing assembly and a method for connecting a high-lift assembly to an aircraft wing that is simple and can be performed by relatively few personnel and that facilitates modular construction of the aircraft wing. Another object of the present invention is to allow such simple and modular construction while enabling accurate orientation of the high-lift assembly (and its connecting assembly) relative to the main wing.

[0008] The object of the present invention is achieved in that the main connector is rotatable relative to the main mounting profile and at least one of the connection assembly and the main wing so as to configure the main connector and the mounting profile to be in a disconnected configuration and a locked configuration, in which the main connector can be moved (e.g., directly, such as translationally relative to the main mounting part and / or non-rotationally) into the main mounting profile to engage with the main mounting profile and removed from the main mounting profile to disconnect from the main mounting profile, and in the locked configuration, movement (e.g., translational movement) between the main mounting profile and the main connector is restricted.

[0009] Thus, the connection assembly can be mounted and locked (e.g., anchored) in place relative to the main wing by simply rotating the primary connector relative to the primary mounting profile. This relatively simple action can be performed by one person, rather than requiring a team of people to secure the primary connector to the primary mounting profile. Furthermore, in rotating the primary connector relative to the primary mounting profile, small misalignments (e.g., due to the configuration of adjacent components, such as a wing box) can be eliminated, where the connection between the screw and the threaded hole would not provide sufficient flexibility to accommodate such misalignments.

[0010] The primary mounting profile can be defined by a mounting sleeve having a circumferentially extending opening therein. The opening can extend along the axial length (e.g., the entire axial length) of the sleeve, and the primary connector can include an elongated connector. The elongated connector can be a bolt, a connecting rod, a tie, a screw, etc. The primary connector can be positioned in the primary mounting profile via the circumferential opening in the primary mounting profile to engage with the primary mounting profile.

[0011] The elongated connector can be generally cylindrical in shape and can include a notch (e.g., a single notch) or two circumferentially opposed notches extending along the axial length of the elongated connector to form a region of lower thickness (e.g., a region of lower diameter) and a region of higher thickness in the elongated connector. The axial length of the circumferentially opposed notches can be equal to or greater than the axial length of the mounting sleeve.

[0012] Along the length of the elongated connector in which the notch is present, the elongated connector may have a profile having the shape of a circle with a removed portion or, in the case of two notches, two removed portions. Thus, the elongated connector may be generally cylindrical in shape, but may include a flat surface along the length of one or more notches. The width of the notch (i.e., taken in a direction perpendicular to the longitudinal axis of the elongated connector) may be equal to the thickness of the elongated connector in the region of the notch (e.g., the lower thickness).

[0013] The shape of the primary connector (eg, an elongated connector) may allow the primary connector to be easily inserted into the primary mounting profile while providing a high level of resistance to movement relative to the primary mounting profile once the primary connector has been configured into the locked configuration.

[0014] The width of the opening may be equal to or greater than the area of ​​lower thickness of the elongated connector, but smaller than the area of ​​higher thickness of the elongated connector. Thus, the elongated connector can be easily introduced into the main mounting profile, but difficult to remove once the elongated connector has been configured in the locked configuration.

[0015] In the decoupled configuration, the primary connector can be removed from the primary mounting joint simply by translational movement of the primary connector relative to the primary mounting joint, such as by translationally moving the primary connector through a circumferentially extending opening in the primary mounting joint. However, in the locked configuration, the primary connector may need to be rotated in order to be removed from the primary mounting joint.

[0016] The primary connector is rotatable relative to the connection assembly. Alternatively, the primary connector may be fixed relative to the connection assembly. In this case, relative rotation of the primary connector and the primary mounting profile may be achieved by rotating the primary mounting profile, which is, for example, rotatable relative to the main wing. In some examples, relative rotation of the primary connector and the primary mounting profile may be achieved by rotating the connection assembly itself relative to the main wing.

[0017] The primary connector can include a stop to engage an axial surface of the primary mounting profile to limit axial movement between the primary connector and the primary mounting profile. The stop can be located on a side of the connector axially opposite the axial side of the connector that engages the primary mounting profile. In some cases, such as where the primary mounting profile engages a middle portion of the primary connector, the primary connector can include two stops, one located at or toward each end of the primary connector. Thus, having a connector can eliminate any risk of vibration or unexpected forces causing axial movement of the primary connector.

[0018] The connection assembly may be in the form of a box, wherein the connection assembly is generally in the shape of a rectangular prism and has solid sides. The box form may allow the connection assembly to be more easily attached to the main wing, for example because the shape of the box form is predictable and can be more easily manipulated by a user wishing to install the connection assembly on the main wing.

[0019] At least one of the primary connector and the primary mounting profile may comprise a tool profile to enable engagement with a tool for the purpose of rotating at least one of the primary connector and the primary mounting profile about the rotation axis. The tool profile may enable the primary connector to be rotated relative to the mounting profile by hand, for example using the fingers, or using a tool such as a screwdriver or an Allen key.

[0020] The primary connector may include or define a longitudinal axis, and the primary mounting profile may include or define a longitudinal axis. The primary connector may be configured to engage with the primary mounting profile such that the longitudinal axis of the primary mounting profile coincides with the longitudinal axis of the primary connector. At least one of the primary mounting profile and the primary connector may be configured to rotate about its longitudinal axis. Thus, the primary connector may be easily rotated about its axis within the primary mounting profile.

[0021] The connection assembly may include a connection structure, and the connection structure may include a primary connector and a secondary connector. The connection structure may additionally or alternatively support other components of the connection assembly, such as slat tracks, roller bearings, etc.

[0022] The connection assembly (e.g., connection structure) can include a first set of primary connectors and primary mounting profiles on one side thereof and a second set of primary connectors and primary mounting profiles on a second side thereof. Thus, both sides of the connection assembly (e.g., connection structure) (e.g., two lateral sides extending away from the main wing or its wing box) can be mounted to the main wing. The connection assembly (e.g., connection structure) can be mounted to a support provided on the main wing, such as one or more ribs (e.g., two ribs) that can protrude from the wing box. The connection assembly (e.g., connection structure) can be mounted to the main wing via a support member that can be connected to the main wing, such as to a spar (e.g., a front spar) of the main wing.

[0023] The primary connector and the secondary connector can be of the same type (e.g., identical, having the same geometry, constructed from the same material, etc.), and the primary mounting profile and the secondary mounting profile can be of the same type (e.g., identical, having the same geometry, constructed from the same material, etc.). This can simplify the process of fastening the high-lift assembly (e.g., the connection assembly) to the main wing, thereby reducing the number of parts required to complete the process.

[0024] The primary and secondary connectors may be of different types, and the primary and secondary mounting profiles may be of different types. The primary and / or secondary connectors may be of the type of elongated members, such as bolts, rods, etc., or may be ties, pads, etc.

[0025] Another aspect relates to a high-lift assembly for a wing according to the aforementioned aspects, the high-lift assembly comprising a high-lift body and a connection assembly, the high-lift body comprising a high-lift structure, the connection assembly comprising a slat track, the slat track being configured to be mounted to a main wing via a roller bearing, such that the slat track movably connects the high-lift body to the main wing, such that the high-lift body can move between a retracted position and at least one extended position. The connection assembly also comprises a primary connector and a secondary connector, and a primary mounting profile and a secondary mounting profile each configured to be connected to the main wing (e.g., connected to the main wing before the primary connector and the secondary connector are mounted to the primary mounting profile and the secondary mounting profile). The primary connector is configured to be mounted to the main wing via the primary mounting profile (e.g., the primary mounting profile may already be connected to the wing), and the secondary connector is configured to be mounted to the main wing via the secondary mounting profile (e.g., the secondary mounting profile may already be connected to the wing), wherein the primary connector is configured to engage the primary mounting profile, and the secondary connector is configured to engage the secondary mounting profile. The primary connector is rotatable relative to the primary mounting profile and at least one of the connection assembly and the main wing so as to configure the primary connector and the mounting profile between a decoupled configuration in which the primary connector can be moved into the primary mounting profile to engage with the primary mounting profile and removed from the primary mounting profile to decouple therefrom, and a locked configuration in which movement between the primary connector and the primary mounting profile is restricted.

[0026] A third aspect relates to a method for connecting a high-lift assembly to a wing for an aircraft according to the aforementioned aspect. The method comprises: preassembling the wing for the aircraft; rotating a primary connector relative to a primary mounting profile so that the primary connector and the mounting profile are in an engaged configuration; engaging the primary connector and the primary mounting profile; rotating the primary connector relative to the primary mounting profile so that the primary connector and the primary mounting profile are in a locked configuration; and connecting a secondary connector to the secondary mounting profile so as to restrict movement between the connection assembly and the main wing.

[0027] The method may comprise configuring the primary connector and the primary mounting profile into a locked configuration before connecting the secondary connector to the secondary mounting profile.

[0028] A fourth aspect relates to an aircraft comprising a wing according to the first aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] exist Figure 1 , an aircraft 1 according to an embodiment of the invention is illustrated. The aircraft 1 comprises a wing 3 formed according to an embodiment of the invention.

[0040] like Figure 1 As shown in , the connection assembly 9 relates to a first connection assembly 91, and the wing 3 includes a second connection assembly 93, which connects the slat 7 to the main wing 5 at a position spaced apart from the first connection assembly 91 along the wing span direction 95, and wherein the second connection assembly 93 is formed like the first connection assembly 91. Figure 1 The wing thickness direction 67 is additionally shown in FIG. Figure 1 The center connection assembly 9 is shown connecting the slat 7 to the main wing 5 , but it will also be appreciated that the connection assembly 9 may be used to connect the trailing edge flap 2 to the wing 5 of an aircraft.

[0041] Figure 2 An example of a connection assembly 9 for a wing of an aircraft is shown, which is configured to connect a slat to a main wing of the aircraft. The connection assembly 9 can be used with Figure 1A wing 1 similar to the wing described in is used in combination, wherein the wing 1 comprises a main wing 5, a slat 7 and a connection assembly 9 (according to the present disclosure) which connects the slat 7 to the main wing 5 in a movably manner so that the slat 7 can be moved between a retracted position and at least one extended position.

[0042] exist Figure 2 In FIG, the connection assembly 9 includes a slat track 17 extending along a track longitudinal axis 19 between a front end 21 and a rear end 23. The front end 21 of the slat track 17 is fixedly mounted to the slat 7. The rear end 23 and the middle portion 25 of the slat track 17 are movably mounted to the main wing 5 via roller bearings 27, so that the slat track 17 can move along the track longitudinal axis 19.

[0043] Figure 3 An alternative connection assembly 109 is illustrated in FIG, this time in the form of a connection assembly box. Here, the slat track 117 is partially located inside the box housing 110, and the roller bearings—on which the slat track 117 sits—are located entirely within the housing 110. To move the slat track 117 between the extended and retracted positions, one or more actuators are provided that penetrate the box housing 110 and allow movement of the slat track 117.

[0044] The connecting components 9 and 109 have the following features: Figure 2 The "open" configuration shown in Figure 3 In both cases of the "box" configuration shown in FIG, the connection assembly can be mounted to the main wing of the aircraft via the mounting device. Figure 4A An example of mounting device 114 is illustrated in Figure 1. Here, box-shaped member housing 110 is installed to the main wing 116 of aircraft via mounting device 114. Mounting device 114 is in the form of bracket, and it comprises a plurality of positions, and bracket is for example connected to box-shaped member 110 at said plurality of positions via known connector. In this example, main wing 116 (and particularly the wing box of main wing) is constructed when box-shaped member 110 is installed thereon. This has the effect that allows box-shaped member 110 to be adapted to make slat track 117 be in the desired angle relative to main wing 116 with respect to the orientation of main wing 116. The required exact orientation relative to main wing of connecting assembly 9,109 can be according to exact connecting assembly 9,109, for example, owing to the manufacturing tolerance during the production of aircraft wing, main wing (comprising wing box) and / or connecting assembly itself and slightly change. Therefore, it is important to ensure that connecting assembly 9,109 is suitably oriented relative to main wing 116 during its production.

[0045] While the desire to modularize the production of aircraft provides advantages in terms of more efficient production and improved processes for repairing and replacing aircraft parts, it has the effect that already assembled (e.g., pre-assembled) parts cannot be adjusted to account for slight anomalies in the dimensions of parts (e.g., parts of a connecting assembly) in order to accurately orient those parts relative to the pre-assembled structure.

[0046] 5A to 5D A connection assembly 209 is shown, comprising a main connector 212 and a main mounting profile 214. Arrows 215 are shown, indicating the direction of movement of the connection assembly 209 relative to the main mounting profile 214, such that the main connector 212 can engage with the mounting profile 214 (here, by moving the main connector 212 into a recess defined by the main mounting profile 214). The main connector 212 is in the form of a cylindrical member protruding from a connection structure 218 of the connection assembly 209, and in this example, has a longitudinal axis oriented perpendicular to the surface of the connection structure 218. Additionally, a portion has been removed from the originally cylindrical main connector 212, resulting in the cylindrical main connector 212 having a flat surface 216 and a reduced diameter in a direction perpendicular to the flat surface 216. The diameter in a direction parallel to the flat surface 216 is the full diameter of the cylindrical connector 212.

[0047] Figure 5A 2. The main mounting profile 214 is also illustrated in FIG. Here, the mounting profile is also generally cylindrical in form and has a recess 220 defined in the middle thereof, so that the main mounting profile 214 is in the form of a sleeve. There is a circumferential opening 222, which in this example extends the entire axial length of the main mounting profile 214, to allow the main connector 212 to be introduced through the opening 222 into the recess 220 in the main mounting profile 214.

[0048] exist 5A to 5D In the example shown in FIG. 2 , the primary connector 212 is rotated so that the flat surface 216 is positioned parallel to the direction of movement illustrated by arrow 215, so that the reduced diameter of the primary connector 212 can be guided through the opening 222. Thus, the reduced diameter is less than the length of the circumferential opening. Once the primary connector 212 has been positioned in the opening, but rotation between the primary connector 212 and the primary mounting profile 214 has not yet been achieved, the primary connector 212 and the primary mounting profile 214 can be considered to be in a decoupled configuration.

[0049] like Figure 5A, the primary connector can then be rotated (as illustrated by arrow 225) (in this example, approximately 90 degrees) so that the flat surface 216 faces the opening and can be oriented perpendicularly or obliquely relative to the direction of movement defined by arrow 215. In this orientation, movement of the primary connector 215 in the opposite direction of arrow 215 will not be possible because the full (larger) diameter of the primary connector 212 is aligned with the opening 222 of the primary mounting profile 214, which has a width that is smaller than the full (larger) diameter of the primary connector 212. In this configuration, the primary connector 212 and the primary mounting profile 214 can be considered to be in a locked configuration.

[0050] It should be noted that in Figure 5A In the configuration shown in , the primary connector 212 is fixed relative to the connection assembly 209 so that no rotational movement is possible therebetween. The primary mounting profile 214 may be mounted on a structural support of the aircraft's main wing, such as a rib protruding from a wing box, a wing spar, or the like.

[0051] on the contrary, Figure 5C An example is illustrated in which the primary connector 212 is rotatable relative to the connection assembly 209. Here, the connection assembly 209 may therefore not need to be rotated to configure the primary connector 212 and the primary mounting profile 214 into a locked configuration.

[0052] exist Figure 5B , further details regarding how the primary connector 212 is sized are illustrated. Here, one acceptable design of the primary connector 212 is illustrated in which the width of the flat surface (perpendicular to the longitudinal axis of the primary connector 212) is equal to the reduced diameter of the primary connector 212 resulting from the removal of portion 212a to create the flat surface 216. When used with the primary mounting profile 214, this sizing of the primary connector 212 can allow the opening 222 to be sized such that the primary connector 212 can be easily positioned in the recess 220, while also securely locking the primary connector 212 in the mounting profile 214.

[0053] Figure 5D yes Figure 5C, wherein arrows 230a, 230b illustrate forces that can be applied to the primary connector 212 relative to the main mounting profile 214. A force in the direction of arrow 230a is directed toward urging the connector 220 into the main mounting profile 214, while a force in the direction of arrow 230b is directed toward urging the connector 220 in the direction of the opening 222. To prevent the primary connector 212 from being accidentally ejected from the recess 220, a force in the direction of arrow 230a is desirable, while a force in the direction of arrow 230b should be avoided. Thus, the opening of the main mounting profile 214 can be positioned relative to the connection assembly to minimize the force in the direction of arrow 230b. For example, the opening 222 can be positioned toward a high-lift body and / or leading edge of an aircraft wing.

[0054] exist Figure 6 , a main connector 212 is illustrated having a stop 224 disposed thereon. The stop 224 is disposed at an axial end of the main connector 212 and helps prevent or limit axial movement of the main connector 212 relative to the main mounting profile 214, thereby preventing the main mounting profile 214 from becoming disengaged from the main connector 212 due to axial movement of the main connector 212.

[0055] Figure 7A and Figure 7B Another example of a connection assembly comprising a main connector 212 and a main mounting profile 214 is illustrated. Here, the main connector 212 and the main mounting profile 214 are illustrated as being in a locked configuration. Although in previous figures the main connector 212 is illustrated as being integrally formed with the connection structure 218 of the connection assembly 209 or fastened via, for example, welding, chemical bonding, etc., in this example the main connector 212 is bolted to the connection assembly via a bolt (or similar elongated connector) 226. Rotation of the main connector 212 about the longitudinal axis 228 of the bolt 226 may be possible, and the bolt may be held in place by a nut or fastener. In Figure 7A , a secondary connector 232 is also shown. The secondary connector 232 may also be or include an elongated connector and may extend through an aperture in the connection structure 218 to be held in place by a nut or fastener, may include threads and connect to a threaded opening on or defined by the connection structure 218, or the like.

[0056] exist Figure 7B In FIG, it can be seen that the bolt 226 extends completely through the connection structure 218, which can provide a safety advantage because a more secure connection between the main connectors 212 can be achieved. Figure 7BIt can also be seen that the connection assembly 209 comprises a main connector 232 located on each lateral side of the connection assembly 209, while the main mounting profile 214 is also located on each lateral side of the connection assembly 209. Thus, the connection assembly 209 can be connected to the main wing at two points thereof and in particular at two points on the lateral surface of its connection structure 218.

[0057] Finally, the connection assembly 209 may include a catch 238 and a corresponding catch arm 236. The purpose of the catch may be to prevent or limit movement of the primary connector 212 and the connection assembly 209 in the direction of arrow 230b in the event that the primary connector 212 fails in some manner. Thus, this is another possible safety feature of the connection assembly 209.

[0058] exist Figures 8A to 8C , the connection assembly 209 is illustrated in the process of being connected to (eg, mounted on) the main wing 5. Figure 8A In FIG, the connection assembly 209 includes a primary connector 212 and a secondary connector 232 as well as a primary mounting profile 214 and a secondary mounting profile 234. Here, the primary connector 212 and the secondary connector 232 have the same form. The primary mounting profile 214 and the secondary mounting profile 234 are each connected (e.g., rotatably connected) to a bracket, which can be connected to a spar of the wing or can be connected to a support structure (e.g., a rib) protruding from the main wing (e.g., from a wing box). In this case, both the primary connector 212 and the secondary connector 232 can be rotated (or both the primary mounting profile 214 and the secondary mounting profile 234 can be rotated) so that the connectors 212, 232 can be inserted into the recesses 220 of the primary mounting profile 214 and the secondary mounting profile 234. Here, when the aircraft is on the ground, the connection assembly moves vertically relative to the orientation of the main wing 5.

[0059] exist Figure 8B In the case of FIG, the connection assembly 209 is shown to be moved horizontally relative to the main wing when the aircraft is on the ground. Here, the secondary connector 232 is in the form of a connection pad that can be slid into a secondary mounting profile 234 defined by a bracket or support structure (e.g., a rib) of the aircraft's main wing. The pad can fulfill the function of preventing the connection assembly from rotating, in particular about the primary connector, which could accidentally release the connection between the primary connector and the mounting profile.

[0060] Figure 8CAnother example of a connection assembly 209 that engages a main wing (e.g., a bracket connected to the main wing) is shown. Here, two sides of the connection assembly are shown. On one side, a primary connector 212 and a primary mounting profile 214 are shown, wherein on that side of the connection assembly 209, a secondary connector 232 and a secondary mounting profile 234 are identical. On the opposite lateral side of the connection assembly, the primary connector 212 and the secondary connector 232 are both in the form of connection pads. The connection pads described may not be able to rotate (e.g., they may be fixed relative to the connection assembly 209) and may simply fit into a recess defined in the main wing 5.

[0061] exist Figures 9A to 9E , an alternative connection concept is shown. Figure 9A The diagram shows a concept in which the primary connector 212 is spherical in shape, with a portion removed, similar to what has been described previously. The primary mounting profile 214 is in the form of a socket 214 that can receive a spherical element and can rotate about it. The secondary mounting profile 234 and the secondary connector 212 can simply be in the form of two flanges that can be connected together, for example, by screws.

[0062] Figures 9B to 9E This connection concept is further illustrated. Here, the primary connector can simply be in the form of a bolt passing through a flange (primary mounting profile 214), and the secondary connector 232 and secondary mounting profile 234 can be similar. In each case, it should be noted that the connection of the primary connector 212 to the primary mounting profile 214 allows rotation about the central axis of the primary connector 212, while the tightening of the secondary connector 232 to the secondary mounting profile 234 can prevent or limit said rotational movement. Generally, this concept can allow the connection assembly 209 to be easily moved to a desired position or orientation (e.g., relative to the main wing 5).

[0063] 10A to 10DA perspective view of the connection between the high-lift assembly, including the connection assembly 209 and the high-lift body 206, is shown. Here, the primary connector 212 is in the form of an elongated connector having two oppositely (e.g., diametrically) arranged notches 240 extending along the length of the elongated connector. The oppositely arranged notches 240 have the effect of creating a longitudinally extending region of reduced thickness in a direction perpendicular to the flat longitudinally extending surface formed by the notches. Furthermore, the elongated connector includes a stop 224 at one end thereof, which in this case includes an indicator 242 in the form of a protrusion. Furthermore, the elongated connector includes a tool profile 244 (in this case in the form of a hexagonal notch, for example for an Allen key) that can be used to allow the elongated connector to be rotated about an axis 246 in order to configure the primary connector 212 and the primary mounting profile 214 between a decoupled configuration and a locked configuration.

[0064] Figure 10B 2 shows a bracket 248 which can be mounted to a main wing of an aircraft (eg a front spar). The bracket 248 in this case defines a primary mounting profile 214 and two secondary mounting profiles 234 which correspond to the Figure 10C and Figure 10D As in the previously illustrated figures, the main mounting profile 214 is in the form of a cylindrical sleeve (in this case integrally formed with the rear panel of the bracket 248) comprising a circumferential opening extending along the length of the main mounting profile.

[0065] In this case, the connection structure 218 may surround and support other components of the connection assembly 209, such as the slat track, as may be seen in FIG. Figure 10C and Figure 10D This allows for a lighter construction that can be produced more easily in the desired shape.

[0066] In use, the primary connector 212 can be coupled to the connection structure 218 (e.g., through an opening in the structure), and the area of ​​reduced thickness of the primary connector can then be aligned with the opening in the primary mounting member 214 to allow the primary connector 212 to be inserted into the recess formed by the primary mounting member 214. When inserted and in the uncoupled configuration, the indicator 242 points to a known position indicating that the primary connector and the mounting profile are in the uncoupled configuration. The connector can then be rotated about the axis 246 of the connector (in this example, counterclockwise) to change the primary connector 212 and the mounting profile 214 into a locked configuration, thereby preventing the primary connector 212 from being removed from the mounting profile 214 without rotating the connector 212.

[0067] Finally, to prevent connection assembly 209 from rotating about primary connector axis 246, two secondary connectors may be secured to the connection structure via secondary mounting profiles provided on bracket 248. Secondary connector 232 may be elongated and positioned through an opening in the connection structure to connect connection structure 218 to secondary connector 232 and prevent rotation of the connection structure about axis 246.
