Description

Technical Field

[0001] The invention relates to a wing for an aircraft. Other aspects of the invention relate to a high lift assembly for such a wing and a method for connecting a high lift body to a connection assembly, as well as to the aircraft itself.

[0002] One aspect of the present invention relates to a wing for an aircraft. The wing comprises a main wing and a high lift assembly. The main wing comprises a fixed leading edge having an outer skin, and the high lift assembly comprises a high lift body and a connection assembly. Background Art

[0003] The high lift body may be, for example, a slat, a Krueger flap, a droop nose / drooping leading edge flap, or the like, or include, for example, a slat, a Krueger flap, a droop nose / drooping leading edge flap, or the like, and the high lift body additionally includes a high lift structure including or defining an internal volume portion. The high lift structure may include, for example, an outer skin and one or more spars, such as a front spar and a rear spar of the high lift body. The internal volume portion may be a closed volume portion.

[0004] The connection assembly extends through an opening in an outer skin located at a fixed leading edge of the main wing to movably connect the high-lift body to the main wing so that the high-lift body can move between a retracted position and at least one extended position (e.g., a fully extended position and a partially extended position). The connection assembly also includes an elongated track and a first connector and a second connector, wherein the elongated track is mounted to the wing via a bearing so that the track can move along a longitudinal axis of the track, and the first connector and the second connector connect the elongated track to the high-lift body at a first end of the elongated track. The bearing can be any suitable bearing, such as a roller bearing.

[0005] The high-lift body is configurable to a retracted position, for example, configured to a retracted position such that the first connector is located between an interior volume in the high-lift body and an outer skin of the main wing. The second connector is an elongated connector having a longitudinal axis oriented transverse to a leading edge of the high-lift body and connected to the high-lift body so as to allow translational movement between the high-lift body and the second connector along a longitudinal axis of the second connector. The high-lift structure includes an opening through which the elongated track extends such that the second connector is positioned in the interior volume of the high-lift body.

[0006] As described above, the longitudinal axis of the second connector can be oriented transversely to the leading edge of the high lift body, for example, non-parallel to the leading edge of the high lift body. The orientation of the longitudinal axis can be in the flight direction, transverse to the span direction, perpendicular to the leading edge of the high lift body, etc.

[0007] Aircraft wings, such as commercial aircraft wings, use high lift devices to increase wing area and wing camber, thereby increasing lift during takeoff and landing. Typically, high lift devices are located at the leading and trailing edges of the wing, with slats being an example of a commonly used high lift device, which may be referred to as a high lift body as above. High lift devices are typically supported by elongated rails, which may be curved and connected to the high lift devices at interfaces, such as by ribbed knuckles, bolts, connectors, and the like.

[0008] In existing designs, interfaces including ribbed knuckles, bolts, connectors, etc. require large cutout areas in the skin of the main wing, particularly in the skin of the fixed leading edge. This large cutout enables the high-lift body to move to a fully retracted position relative to the main wing, but the large cutout also provides a relatively large opening when the high-lift body is in the extended position, through which rain and dirt can enter the main wing and contact the components in the main wing, and the opening can also be a source of a large amount of noise. Some existing designs are known in which relatively small cutouts are required in the skin of the main wing by positioning the interface inside a portion of the high-lift body, but in such designs, the complexity increases, so that an opening is required to enter in the leading edge skin of the high-lift body. Therefore, another opening is formed, through which dirt and water can enter, and this opening may generate noise and additional drag during flight, and therefore the problem is not solved. Summary of the invention

[0009] It is an object of the present invention to provide a connection assembly and a high lift body having a simple design which reduces any opening area required in the main wing.

[0010] The purpose is achieved in that the high lift body can be configured to a retracted position so that the first connector is positioned between the internal volume portion in the high lift body and the outer skin of the main wing, while the second connector has a longitudinal axis oriented transverse to the leading edge of the high lift body and can intersect with the longitudinal axis of the track, and the second connector is connected to the high lift body so as to allow translational movement along the longitudinal axis between the high lift body and the second connector. Additionally, the high lift structure includes an opening through which the elongated track extends so that the second connector is positioned in the internal volume portion of the high lift body. Therefore, in the retracted position, the first connector and the second connector are positioned outside the main wing, and the second connector is simply connected to the high lift body so as to be able to perform translational movement between the high lift body and the second connector. Therefore, the main wing can include a smaller opening in the outer skin of the main wing, while no additional or additional opening is required in the skin of the high lift structure to allow access to the second connector located in the internal volume portion of the high lift structure.

[0011] The high lift body may be a slat. The internal volume portion may be a slat box.

[0012] The second connector may have a longitudinal axis oriented perpendicular to the leading edge of the high lift body.Alternatively, the second connector may have a longitudinal axis oriented in the direction of flight of the wing.

[0013] The first connector may allow translational movement of the elongated track along an axis transverse to the longitudinal axis of the track. The transverse axis may be perpendicular to the longitudinal axis of the track.

[0014] The first connector and the second connector may both be elongate connectors and may allow the elongate track to rotate about a longitudinal axis of each elongate connector.The longitudinal axis of the first connector may be oriented perpendicular to the track longitudinal axis.

[0015] The longitudinal axis of the second connector may intersect the track longitudinal axis.

[0016] The elongated track may include an elongated connection portion to which the first connector and the second connector may be fixedly connected. The elongated connection portion may be at least partially positioned between the internal volume portion and the outer skin of the main wing. The elongated connection portion may include a longitudinal axis parallel to the longitudinal axis of the second connector.

[0017] The longitudinal axis of the second connector may be oriented parallel or obliquely relative to the leading edge of the high-lift body.

[0018] The first connector and the second connector may be directly connected to the high-lift body. The first connector and the second connector may be directly mounted to the high-lift body. The second connector may be directly connected to the high-lift body to allow up to three rotational degrees of freedom (e.g., one, two, or three rotational degrees of freedom) and one translational degree of freedom between the second connector and the high-lift body.

[0019] The first connector and the second connector may connect the elongated track to the high lift body via a coupling, and the coupling may allow rotation of up to three degrees of freedom (e.g., one, two, or three degrees of freedom) of the elongated track. The coupling may allow rotation of up to three degrees of freedom about an axis transverse to the leading edge of the wing.

[0020] The wing may include a sealing arrangement between the opening in the main wing and the elongate rail.

[0021] A second aspect relates to a high lift assembly for a wing consistent with the previous aspect. The high lift assembly comprises a high lift body (which may be a slat, but may also be a Krueger flap or a droop nose / leading edge droop flap) comprising a high lift structure defining an internal volume.

[0022] The high lift body additionally includes a connection assembly that can be configured to extend through an opening in an outer skin located at a fixed leading edge of a main wing of the aircraft to movably connect the high lift body to the main wing so that the high lift body can move between a retracted position and at least one extended position. The connection assembly includes an elongated track and a first connector and a second connector, the elongated track being configured to be mounted to the main wing via a bearing so that the track can move along a longitudinal axis of the track. The first connector and the second connector connect the elongated track to the high lift body at a first end of the elongated track.

[0023] According to a second aspect, the high lift body is configurable to a retracted position such that the first connector is positioned between an interior volume in the high lift body and an outer skin of the main wing, and the second connector is an elongated connector having a longitudinal axis oriented transverse to a leading edge of the high lift body and connected to the high lift body so as to allow translational movement between the high lift body and the second connector along the longitudinal axis of the second connector. The high lift structure additionally includes an opening through which the elongated track extends such that the second connector is positioned in the interior volume of the high lift body.

[0024] A third aspect relates to a method for connecting a high-lift body to a connection assembly. The method includes providing a high-lift body including a high-lift structure having an interior volume portion defined therein; positioning at least a portion of a connection assembly in the interior volume portion via an opening in the high-lift body, the connection assembly including an elongated track having a longitudinal axis of the track; connecting the connection assembly to the high-lift body via a first connector located outside the interior volume portion and an elongated second connector located inside the interior volume portion so as to allow translational movement between the high-lift body and the second connector along the longitudinal axis of the second connector; and orienting the second connector inside the interior volume portion so that the longitudinal axis of the second connector is oriented transverse to the leading edge of the wing.

[0025] A fourth aspect relates to an aircraft comprising a wing according to the preceding aspect, the wing comprising a high lift assembly according to the preceding aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 5 An aircraft comprising a wing according to the present disclosure. DETAILED DESCRIPTION

[0031] Figure 1 A connection assembly 509 for a wing of an aircraft according to the prior art is shown, the connection assembly 509 being configured to connect a slat to a main wing of the aircraft. The connection assembly 509 can be used in conjunction with a wing comprising a main wing 505, a slat 507, and the connection assembly 509 connecting the slat 507 to the main wing 505 in a movably manner.

[0032] exist Figure 1 , the connection assembly 509 includes a slat track 517 extending between a front end 521 and a rear end 523 along a track longitudinal axis 519 and having a middle portion 525 between the front end 521 and the rear end 523. The front end 521 of the slat track 517 is fixedly mounted to the slat 507. The rear end 523 and the middle portion 525 of the slat track 517 are movably mounted to the main wing 505 via roller bearings 527, so that the slat track 517 can move along the track longitudinal axis 519.

[0033] As shown, the front end 521 of the slat track 517 is in the form of a knuckle that includes a connector for connecting the slat track 517 to the slat 507. The front end 521, and therefore the knuckle, extends from the slat 507 and into the main wing 505. This means that an opening or cutout at least as large as the cross-sectional area of ​​the knuckle is required in the main wing.

[0034] exist Figure 2A , a portion of a wing 2 of an aircraft is illustrated. The wing 2 comprises a main wing 5 connected to a high lift assembly 7 comprising a high lift structure 8 and a connection assembly 10. The connection assembly 10 is connected to the high lift structure 8 via a first connector 12 and a second connector 14, which are connected to a first end of an elongated rail 16. The elongated rail 16 extends through an opening 18 in an outer skin 20 of the main wing 5, the opening 18 defining a leading edge of the outer skin 20 of the main wing 5, and the elongated rail 16 is mounted to the main wing via a bearing, such as a roller bearing, for the sake of clarity. Figure 2A The bearing is only partially shown in the figure, but note that Figure 1An example of a roller bearing can be seen in . For the sake of clarity, a sealing arrangement that may be present between the elongated track 16 and the hole 18 has also been omitted. The high lift assembly 7 comprises a high lift body, in this case a slat, comprising a high lift structure 8, wherein the high lift structure 8 defines an internal volume 22, and the elongated track is movable along a track longitudinal axis 24 to allow the high lift body to move between a retracted position and at least one extended position. Figure 2A , the high-lift body is shown in a retracted position.

[0035] like Figure 2A As shown, the high-lift structure 8 includes a front skin 26 and a rear skin 28, which together define an interior volume 22 in the high-lift structure 8. The rear skin 28 is additionally shaped to define a recess between the outer skin 20 of the main wing 5 and the interior volume 22. The first connector 12 is positioned in the recess and, in this example, is connected to a lug 30 that is connected to the rear skin 28 of the high-lift structure 8 (e.g., defined by or mounted on the rear skin 28 of the high-lift structure 8).

[0036] The elongated track 16 comprises a curved track portion 34 and an elongated connecting portion 32, which extends obliquely relative to the track longitudinal axis 24 at the intersection with the curved track portion 34. The second connector 14 is connected to the elongated connecting portion 32 and can be fixedly connected to the elongated connecting portion 32. The first connector 12 is also connected to the elongated connecting portion 32 via a link 36 in this example, however it should be noted that other connection methods are also possible, such as direct connection.

[0037] Here, the first connector 12 is an elongated connector (e.g., in the form of a bolt, rod, etc.) and is connected to the high-lift structure 8 such that the longitudinal axis of the first connector 12 is positioned perpendicular to the track longitudinal axis 24 and / or parallel to the leading edge of the high-lift assembly 7. The second connector 14 (which is also an elongated connector) can be described as being oriented generally perpendicular to the first connector 12 and supported by the high-lift structure 8 in this example, but can be oriented (or considered to be oriented) transverse to the leading edge of the high-lift assembly 7 and intersecting the track longitudinal axis 24, perpendicular to the leading edge of the high-lift assembly 7, non-parallel to the leading edge of the high-lift assembly 7, oriented in the direction of flight, oriented transverse to the span direction of the wing, etc. Here, the high-lift structure 8 includes a plurality of support spars 38, one of which supports the second connector 14 so as to allow translational movement of the second connector 14. In this example, rotational movement of the second connector 14 about its longitudinal axis may also be allowed. Thus, the second connector 14 may only need to be directed into engagement with the high-lift structure 8 (eg, the spar 38 of the high-lift structure).

[0038] The rear skin 28 of the high lift structure 8 includes an opening 40 therein that allows the elongated connecting portion 32 of the elongated rail 16 to extend therethrough so that the second connector 14 can engage with the high lift structure 8, in this example with the spar 38 of the high lift structure. Figure 2A When the second connector 14 is oriented as illustrated in FIG. 4 and simply supported on the high lift structure 8, the second connector and at least a portion of the elongated connecting portion 32 of the elongated rail 16 can be directed through the relatively small opening in the rear skin 28 without requiring any other access openings (e.g., access openings in the front skin 26) to establish a connection with the high lift structure 8. Therefore, the structural integrity of the high lift structure 8 is not unnecessarily weakened by the opening 40, and the smaller opening may allow less ingress of water, dirt, etc.

[0039] Similarly, if Figure 2A As can be seen in the figure, the opening in the outer skin 20 of the main wing 5 only needs to be large enough to allow the curved track portion 34 of the elongated track 16 to pass therethrough, while both the first connector 12 and the second connector 14 are located outside the main wing 5 in the retracted position and the extended position. Having a smaller opening in the outer skin 20 of the main wing 5 reduces the ingress of water and dirt therein and the noise generated by the main wing in flight. In addition, the structural integrity of the main wing is less affected by the smaller opening in the main wing.

[0040] Figure 2B yes Figure 2A3D illustration of a high lift structure 8 and an elongated rail 16. Here, a first connector 12 and a second connector 14 are schematically illustrated.

[0041] In this example, the link 36 connecting the first connector 12 to the elongated connecting portion 32 is omitted, and the first connector 12 is simply illustrated as an elongated connector that allows one degree of translational freedom and one degree of rotational freedom. The first connector 12 allows the elongated rail 16 to perform translational movement along the longitudinal axis of the first connector 12 at the point where it is connected, and allows rotational movement about the longitudinal axis of the first connector 12.

[0042] In this example, the second connector 14 allows translational movement along its longitudinal axis, as well as rotational movement about its longitudinal axis. Figure 2B In FIG. 1 , it can also be seen that the second connector is positioned within the interior volume 22 of the high lift structure 8. Those skilled in the art will also appreciate that the second connector 14 may define or engage a spherical bearing to allow for other rotational degrees of freedom (e.g., three rotational degrees of freedom), such as rotational freedom about a vertically extending axis and rotational freedom about an axis extending in the span direction. The spherical bearing may be provided in FIG. Figure 2B 1 is shown as a bearing seat into which the second connector 14 can be inserted, wherein the bearing seat can be connected to the high lift structure 8 (e.g. slat). It will also be understood by those skilled in the art that the role of the spherical bearing is to prevent unacceptably high force / stress concentrations at the junction area between the connector 14 and the high lift structure 8 due to bending of the wing and / or the high lift structure 8 during flight.

[0043] Those skilled in the art will also appreciate that such spherical bearings - although not illustrated in detail - may be present in the described example at the contact points between the connection points of both the first bearing 12 and the second bearing 14 to the high lift structure 8 in order to prevent inadmissible force / stress concentrations.

[0044] FIG. 3A to FIG. 3C Various alternative connection arrangements between the high lift structure 8 and the elongated rail 16 are illustrated, wherein the first connector 12 may be oriented parallel to (eg, substantially parallel to) the second connector 14. FIG. 3A to FIG. 3C In each of the two structures, the second connector 14 is identically connected to the high lift structure 8 and therefore for the sake of brevity this connection will not be described again.

[0045] Figure 3A The following example is illustrated: in this example, the elongated connecting portion 32 includes a protrusion 42, and the first connector 12 is connected to the protrusion 42. Figure 2A and Figure 2BSimilar to the example of , the first connector 12 can allow two degrees of freedom of the high lift structure 8 relative to the elongated track 16: translational movement along its longitudinal axis and rotational movement about its longitudinal axis. Figure 2B As described, a spherical bearing may be present at the interface between the first connector 12 and the high lift structure 8 to provide an additional two rotational degrees of freedom. Figure 3A The example of may be preferred in some cases where it is desired that translational movement is desired in the same direction at both the first connector 12 and the second connector 14. Figure 2A For example, the first connector is connected to the high-lift structure 8 via a lug, which can provide some limitation on the translational movement of the high-lift structure 8 relative to the elongated track 16, such as preventing the high-lift structure 8 from being disconnected from the elongated track 16.

[0046] Figure 3B A similar configuration is shown, but instead of the elongated connecting portion 32 including the protrusion, the elongated connecting portion 32 includes a link 36 similar to Figure 2A The connecting member 36 is rotated, for example, by 90 degrees. Figure 2A and Figure 3A In the case of , the first connector 12 is connected to the high-lift structure 8 via lugs. Figure 2A and Figure 2B The first connector 12 allows the Figure 3A The degrees of freedom of the first connector are the same as the degrees of freedom.

[0047] Alternatively, Figure 3B The first connector 12 may be rigidly fixed to the high lift body structure 8 such that the link 36 interfaces with both the first connector 12 and the elongated rail 16 via a spherical bearing.

[0048] Figure 3C The first connector 12 is similarly illustrated connected to the elongated track 16 via a link 36. However, in this example, the lug 30 has a forked configuration that connects to the first connector 12 at either end of the lug 30, thereby limiting translational movement of the high lift structure 8 relative to the elongated track 16. Figure 3C An example of this could allow for Figure 3A and Figure 3B The degrees of freedom described are the same as the degrees of freedom.

[0049] FIG. 4A to FIG. 4CAn example of a wing 2 is illustrated, the wing 2 includes a high lift assembly 7, the high lift assembly having a connection assembly 10 and a high lift structure 8, wherein the connection assembly 10 is connected to the high lift structure 8 via a coupler 44. The coupler 44 includes at least one linkage, the at least one linkage connecting the elongated connection portion 32 of the elongated track 16 to a coupling connector 46, which is an elongated connector. Here, the coupler 44 includes two linkages, namely one linkage connected to the second connector 14 and one linkage connected to the elongated connection portion 32 and / or the first connector 12. As can be seen, the coupler 44 includes at least one sleeve (e.g. one or two sleeves) connected to the coupling connector 46. The coupling connector 46 can be oriented parallel to the second connector 14, or can be oriented obliquely to the second connector 14, for example so that the longitudinal axis of the second connector 14 intersects the longitudinal axis of the coupling connector 46. The coupling connector 46 can be oriented transverse to the leading edge of the high lift body, as in the case of the second connector 14. The coupling connector 46 may be oriented non-parallel to the leading edge of the high lift body, perpendicular to the leading edge of the high lift body, etc. The coupling connector 46 may be considered to have its longitudinal axis oriented in the direction of flight relative to the wing 2, or transverse to the spanwise direction of the wing 2. The orientation of the coupling connector 46 may aid in positioning the elongated connector within the interior volume 22.

[0050] Due to the sleeve form of the coupler 44, the coupler 44 allows the connected elongated connection portion 32 to rotate about the longitudinal axis of the coupling connector 46. In addition, the coupler 44 can allow the elongated connection portion 32 to translate along the longitudinal axis of the coupling connector 46, for example, parallel to the longitudinal axis of the coupling connector 46, due to the offset between the coupling connector 46 and the elongated connection portion 32 caused by the length of the coupler 44.

[0051] Additionally, from Figure 4A and Figure 4B It can be seen that the first connector 12 has been incorporated into the coupling 44, wherein, for example Figure 2A The link 36 to which the first connector 12 is connected now takes the form of a coupling 44, and the first connector is now incorporated into the coupling connector 46. Figure 4C , the 3D schematic diagram illustrates that the coupling 44 provides both rotational and translational motion about the axis of the coupling connector 46, while for example Figure 2B The degrees of freedom provided by the first connector and the second connector also still exist.

[0052] Thus, having the coupling 44 allows for additional degrees of freedom when attaching the high lift structure 8 to the main wing 5, and allows for movement of the high lift body relative to the main wing 5. This can help prevent the attachment between the high lift structure 8 and the main wing 5 from becoming overly constrained, thereby causing unnecessary and undesirable forces to act in the high lift structure 8 and / or the main wing 5. In some examples, there may be multiple connection assemblies 10 connecting the high lift structure 8 to the main wing 5. It may be desirable to have one connection assembly 10 such as Figure 2A and Figure 2B as well as FIG. 3A to FIG. 3C As shown, in this connection assembly 10, the elongated connection part 32 is directly connected to the high lift structure 8 - the so-called "main" connection, and has the following remaining connection assembly 10: FIG. 4A to FIG. 4C In the embodiment, the remaining connection assembly has an elongated connection portion 32 which is connected to the high-lift structure 8 via a coupling 44 - a so-called "slave" connection. Thus, over-constraint of the connection between the connection assembly 10 and the high-lift structure 8 can be avoided.

[0053] exist Figure 5 In FIG. 1 , an aircraft 1 according to an embodiment of the invention is illustrated. The aircraft 1 comprises a wing 2 formed according to an embodiment of the invention.

[0054] like Figure 5 As shown, the connection assembly 10 is illustrated as a first connection assembly, and the wing 5 includes a second connection assembly, which connects the slat 7 to the main wing 5 in a position spaced apart from the first connection assembly along the wing span direction 95, and wherein the second connection assembly can form a "master" connection with the slat 7, while the first connection assembly can form a "slave" connection with the slat 7, as described above. Figure 5 The wing thickness direction 67 is additionally illustrated in FIG. Figure 5 In the embodiment shown, the connection assembly 10 is shown as connecting the slat 7 to the main wing 5 , it should also be understood that the connection assembly 10 can be used to connect the trailing edge flap 2 of an aircraft to the wing 5 .
