Description

Technical Field

[0001] The invention relates to a movable flow-shaped body device for an aircraft, a wing having such a movable flow-shaped body device and an aircraft having such a wing. Background Art

[0002] Movable flow-shaped bodies such as leading edge slats and trailing edge flaps are usually supported by drive mechanisms on the wings or other parts of the aircraft. The flow-shaped bodies are usually moved by main joints, while the slave joints are used to support the corresponding flow-shaped bodies and maintain a certain alignment of the flow-shaped bodies. During the installation of the flow-shaped bodies to the aircraft, the alignment needs to be adjusted to compensate for manufacturing tolerances. In order to support the flow-shaped bodies on the drive mechanisms, knuckle joints are usually used. Summary of the invention

[0003] With known mechanical joints, the size of the flow bodies is limited by the space available for these mechanical joints. Particularly for outer positions, a certain minimum height or width of the flow body is required to allow the use of the mechanical joint at a sufficiently outer side or end region of the respective flow body.

[0004] It is therefore an object of the present invention to provide an alternative movable flow profile device which enables a greater length, a smaller width, a greater curvature and / or an improved assembly behavior.

[0005] This object is achieved by a movable flow body device for an aircraft having the features of the invention. Advantageous embodiments and other developments can be derived from this document.

[0006] A movable flow-shaped body device for an aircraft is proposed, the flow-shaped body device comprising: an elongated flow-shaped body, the flow-shaped body having a main extension axis; a first mechanical joint, the first mechanical joint being coupled to the flow-shaped body in a first position along the main extension axis, the first mechanical joint having a first support component; a second mechanical joint, the second mechanical joint being coupled to the flow-shaped body in a second position along the main extension axis, the second mechanical joint having a second support component; and a third mechanical joint, the third mechanical joint being coupled to the flow-shaped body in a third position along the main extension axis, the third mechanical joint having a third support component, wherein the first support component, the second support component and the third support component are rigidly attached to the flow-shaped body, wherein the first mechanical joint comprises a first rotating device, the first rotating device being configured to rotatably couple a first support rod to the first support component of the first joint so as to form a rotation on the first support component. The hinge parts are connected to each other with a second end facet of the hinge part, and the third end facet of the hinge part is connected to each other with a second end facet of the hinge part, and the third end facet of the hinge part is connected to each other with a third end facet of the hinge part.

[0007] A flow body is to be understood as a component that is movably supported on an aircraft for the purpose of enhancing the aerodynamic properties of the aircraft. For example, a flow body may be a movable leading edge device, such as a slat, a flap, a drooping nose or the like. However, a flow body may also be a trailing edge device, such as a movable flap. Such a flap may be a high-lift flap that will move on a more or less complex path of motion. The trailing edge device may also include an aileron that is only rotatably supported on a fixed hinge line. However, a hybrid form, such as a form realized in the form of a flaperon, is also possible. It should be understood that the extension of the flow body along the main axis of extension significantly exceeds the extension in other spatial directions. Therefore, the flow body is elongated.

[0008] The flow body may include a generally surface-like shape, or the flow body may include a more complex three-dimensional shape having an internal reinforcement structure and at least one skin surrounding the corresponding reinforcement structure. In order to connect the corresponding flow body to the drive mechanism, a mechanical joint is provided. In a general embodiment, these mechanical joints may include a first mechanical joint, a second mechanical joint, and a third mechanical joint. For a better understanding, the movable flow body device includes components, joints, and parts to be attached to the drive mechanism of the aircraft. The drive mechanism exemplarily includes a first support rod, a second support rod, and a third support rod, which provide the desired movement and keep the flow body in all desired positions.

[0009] All mechanical joints include a support component that is rigidly attached to the flow body. By rigidly attaching the support component, an attachment point is provided with a fixed spatial relationship with the flow body to which the drive mechanism can be connected in a rotatable manner. Therefore, the first mechanical joint includes a first rotating device, which is configured to receive a part of a first support rod to form a first hinge point, and the first support rod is part of the drive mechanism. When such a first support rod is attached to the first rotating device, the first mechanical joint is connected to the first support rod. In this case, the first rotating device is directly connected to the first support component.

[0010] It will be appreciated that during normal operation of the aircraft, the flow body is generally not intended to rotate freely about the hinge point or hinge line. Instead, the flow body should maintain a fixed spatial relationship with the drive mechanism. Therefore, at least one further element is required on each mechanical joint to align the flow body relative to the drive mechanism as desired and to fix this alignment. The hinge line therefore allows only a holding function without binding stresses and allows the alignment between the flow body and the mechanical joint to be adjusted by rotating about the hinge line and the rotational position to be fixed.

[0011] The design and setting of the second mechanical joint and the design and setting of the third mechanical joint are very similar to the first mechanical joint. However, the second support rod and the third support rod are connected to the corresponding second support part or the third support part via a connecting plate. For example, this can achieve a compensating movement between the corresponding support part and the corresponding support rod in the direction of the main extension axis. The first hinge point, the second hinge point and the third hinge point span the hinge line to extend through along the first position, the second position and the third position.

[0012] By inverting the orientation of one of the connecting plates, a significant displacement of the second or third hinge point relative to the corresponding support rod can be achieved. Thus, one of the second or third support rods can be arranged on one side of the associated hinge point, while the other of the second or third support rods can be arranged on the other side of the associated hinge point. This allows the displaced hinge point to be included in an area with a very narrow end, which would otherwise not allow the reception of a mechanical joint with a hinge point. Thus, the connecting lines between the hinge line and all the supporting parts or support rod ends can enclose a non-zero angle with the hinge line. By displacing the corresponding hinge point outwards, for example in the chord direction of the flow body, the corresponding mechanical joint can be placed in a laterally outward position of the tapered end of the slender flow body. Thus, the movable flow body device according to the present invention allows a longer and / or more tapered and / or more slender flow body while maintaining the same adjustability.

[0013] For the sake of completeness, it is pointed out that the terms "first", "second" and "third" should not be interpreted as an order from an inner position to an outer position or the like. These terms are only used to distinguish different components regardless of their positions.

[0014] In a preferred embodiment, the connecting plate comprises an attachment end and a support end, wherein the attachment end is attached to one of the corresponding support rod and the corresponding support component, wherein the support end is attached to the other of the corresponding support rod and the corresponding support component, wherein the attachment end comprises at least two flexible attachment points attached to the connecting plate to maintain the desired orientation, and wherein the support end comprises a single flexible attachment point attached to the connecting plate to allow rotational movement. The flexibility of the attachment point can be achieved by a spherical bearing or other device that allows the connecting plate to move slightly to allow displacement between the corresponding support rod and the corresponding support component. It is particularly preferred that the connecting plate is allowed to rotate slightly around the hinge axis generated by the connecting line between the two attachment points on the attachment end. For example, if the flow body conducts thermal expansion, the flexible attachment point allows slight displacement of the corresponding support rod and the support component.

[0015] Furthermore, in an advantageous embodiment, the attachment end of one of the connecting plates is connected to the respective support rod, wherein the attachment end of the other of the connecting plates is connected to the respective support component. Thus, the reversal of the connecting plates is achieved by attaching the connecting plates to the respective support rod in an inverted manner. While one of the connecting plates allows the respective articulation point to be displaced to the support rod itself, the other of the connecting plates determines the respective articulation point on the respective support component. In the case where both support rods are arranged on the same side of the support component, the displacement of the position of the articulation point is only carried out by turning the connecting plate into an inverted orientation, for example turning it upside down.

[0016] In another advantageous embodiment, the arrangement of the second support rod and the second support part and the arrangement of the third support rod and the third support part are inverted relative to each other in a direction transverse to the main extension axis. Thus, the relative positions of the second support rod or the third support rod and their corresponding support parts are interchanged. This can also include an inverted orientation of the corresponding connecting plates, so that one connecting plate can be attached to the support rod with its attachment end and the other connecting plate can be attached to the support part with its attachment end. However, all connecting plates can be attached to the support rod with their attachment ends, or as an alternative, all connecting plates can be connected to the support part with their attachment ends. The reversal of the relative position of the support rods and / or the reversal of the orientation of the connecting plates increases the flexibility of choosing the position of the hinge point.

[0017] Advantageous embodiments further include a first connecting rod, a second connecting rod and a third connecting rod, wherein each of the supporting rods is coupled to one end of one of the connecting rods, wherein the corresponding other end is coupled to the corresponding supporting member at a distance from the corresponding rotating device. The connecting rods are provided for maintaining a fixed spatial relationship between the flow-shaped body and the corresponding supporting rod. For example, the first connecting rod extends between the first supporting member and the first supporting rod at a distance from the first rotating device so as to form a triangle between the first rotating device and the two ends of the first connecting rod. By adjusting the length or the coupling position of the connecting rod, the alignment of the flow-shaped body relative to the supporting rod and thus the adjustment of the flow-shaped body relative to the surrounding components on the aircraft in the installed state is adjusted. For example, the trailing edge of the flow-shaped body can be adjusted to the fixed leading edge of the wing. It is desirable to provide a tension-free state of the flow-shaped body and the supporting rod, while the position of the flow-shaped body meets the requirements regarding the aerodynamic requirements in at least one state of the flow-shaped body, such as the retracted state. This adjustment is an assembly process that can be performed during the installation of the flow-shaped body. During the assembly process, when the flow shape is adjusted, it is locally rotated about the articulation axis or the respective articulation point in the vicinity of the respective connecting rod.

[0018] Furthermore, the first mechanical joint may be a primary joint and the second and third mechanical joints may be secondary joints.

[0019] Preferably, the support member is implemented as a support rib attached to the inner skin of the flow body and comprises a lug or hole for coupling with a corresponding support rod. This is particularly useful for example for a leading edge slat or a trailing edge flap, because the leading edge slat or the trailing edge flap may already include an internal reinforcement structure with a rib and a skin surrounding the rib. The support member in the form of a support rib can be designed to protrude from the interior of the corresponding flow body, thus providing a lug or hole to receive a coupling feature.

[0020] Preferably, the mechanical joint comprises a knuckle joint. The knuckle joint has proven to be a reliable and safe measure for combining rotatable components. Preferably, the first support rod surrounds the first support component in a clamp-like manner by two substantially identical parts. In the second mechanical joint and the third mechanical joint, two connecting plates surround the second support rod or the third support rod. Two connecting rods surrounding the corresponding support rod and the corresponding support component can be used for each support rod to provide the desired connection. Radial adjustment can be provided by using a set of rotatable elements with eccentric holes. By rotating one of these elements, the eccentric hole can be selectively repositioned to provide radial adjustment. For example, the hole can determine the hinge point or the hinge axis. It should be understood that the rotational position of one of the components can be locked by appropriate features to permanently fix this component.

[0021] According to a preferred embodiment, the width of the flow body varies along the main extension direction, wherein one of the second attachment location and the third attachment location is located in the region of minimum width, and wherein the first attachment location is arranged at a distance from the region of minimum width along the main extension direction. The arrangement of the second mechanical joint in the region of minimum width obviously enables a further reduction in width compared to conventional flow body arrangements.

[0022] It is preferred if the first attachment position is a central position between the second and third attachment positions. Thus, both mechanical joints with the connecting plate are arranged out of the center. By displacing the hinge point of one of the mechanical joints, the hinge line can be calibrated to fit into a thinner and narrower flow profile.

[0023] Preferably, the main extension direction is the span direction, wherein the flow body tapers in the outer direction, and wherein the third mechanical joint is arranged in the outer region. Therefore, the outer dimension of the flow body can be designed to be as small as possible. By providing the design according to the invention, the third rotating device is easier to implement and the outer region of the flow body is easier to support.

[0024] As further explained above, preferably, the attachment points of the connecting plates are designed for allowing a lateral displacement of the respective support member and support rod relative to each other.

[0025] The invention also relates to a wing having: a fixed wing part, at least one flow-shaped body device according to the above description; and a drive mechanism having at least a first support rod, a second support rod and a third support rod, wherein the at least one flow-shaped body device is coupled to the first support rod, the second support rod and the third support rod. As further described above, the first support rod and the second support rod are part of the drive mechanism and are driven by a drive unit to extend or retract the corresponding flow-shaped body.

[0026] Furthermore, the flow shape may include at least one of a leading edge high lift device and a trailing edge high lift device.

[0027] Finally, the invention relates to an aircraft having two wings according to the above or at least one flow-shaped body device according to the above description. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Other features, advantages and potential applications of the present invention are derived from the following description of the exemplary embodiments shown in the accompanying drawings. In this regard, all described and / or illustrated features also constitute the object of the present invention individually and in any combination. In addition, identical or similar objects are identified by the same reference numerals in the accompanying drawings.

[0029] Figure 1a and Figure 1b Two mechanical joints in the flow body are shown.

[0030] Figure 2a A diagram of a tapered flow profile and a schematic diagram of a common mechanical joint are shown.

[0031] Figure 2b A second mechanical joint with a modified Figure 2a .

[0032] Figure 3 An aircraft is shown. DETAILED DESCRIPTION

[0033] Figure 1aThe inner part of the flow body 2 is shown, in which the first mechanical joint 4 is coupled to the flow body 2 in the first position 6. Exemplarily, the first position 6 is a central position which is located in the region of the center along the main extension axis, and the main extension axis is the wingspan axis in this case. In this exemplary embodiment, the first mechanical joint 4 includes a first support member 8, and the first support member 8 is a support rib attached to the skin 10 of the flow body 2. A first support rod 12 which is part of the drive mechanism is coupled to the first support member 8 by means of a first rotating device 14, and the first rotating device 14 provides a first hinge point 16 extending through the first support member 8. For example, the first support member 8 includes a through hole, and the first support rod 12 includes two parallel webs 18 which are spaced apart from each other for surrounding the first support member 8. A bolt 20 or a similar component extends through the two webs 18 and the first support member 8 to provide the first rotating device 14. Due to the direct connection between the first support rod 12 and the first support member 8, lateral displacement between the first support member 8 and the first support rod 12 is prevented. Therefore, the first mechanical joint 4 can thus be considered as the main joint.

[0034] In order to maintain a desired rotational alignment between the first support rod 12 and the first support member 8 about the first hinge point 16, a first link 22 is provided. The first link 22 is coupled to both the first support member 8 and the first support rod 12. The first link 22 is arranged at a certain distance from the first rotating device 14 and extends between a first link joint 24 and a second link joint 26. At the second link joint 26, radial adjustment can be accomplished. For this purpose, the second link joint 26 is eccentric. A locking member 28 is provided for locking the radial adjustment. Therefore, by adjusting the second link joint 26, the effective length of the first link 22 can be adjusted, which in turn adjusts the alignment of the flow body 2 relative to the first support rod 12. Therefore, the flow body 2 is locally assembled on the first mechanical joint 4.

[0035] In Figure 1b it, a second mechanical joint 30 in the form of a slave joint is shown. Here, there are provided: a second support member 32 which is coupled to a second link 34 at the first link joint 24; and a connecting plate 36 which is flexibly attached to a second support rod 38 and is rotatably and flexibly coupled to a second rotating device 40 at the second support member 32. The second rotating device 40 determines a second hinge point.

[0036] The connecting plate 36 includes an attachment end 42 and a support end 44. When the attachment end 42 is flexibly attached to the second support rod 38, for example, by using a spherical bearing, the support end 44 carries the second rotating device 40. Here, the support end 44 may also include a spherical bearing for allowing movement flexibility.

[0037] The spherical bearings for connecting the connecting plate 36 with the second support part 32 and the second support rod 38 allow for a lateral displacement between the second support part 32 and the second support rod 38. Thus, in the event of thermal expansion or other influences, the first mechanical joint 4 maintains the lateral position between the first support rod 12 and the first support part 8 in the lateral direction, while the second mechanical joint 30 is capable of a compensating movement between the second support part 32 and the second support rod 38 in the lateral direction.

[0038] In addition, the second connecting rod 34 is rotatably coupled to the second supporting rod 38, and the second connecting rod 34 can be adjusted in the radial direction via the second connecting rod joint 26. Therefore, the alignment of the flow body 2 can also be assembled relative to the second supporting rod 38.

[0039] As an example, the second mechanical joint 30 is provided at a second position 46, which is preferably more inboard or at a position having the maximum width of the flow body 2. It should be understood that the flow body 2 tapers in the span direction so that the outer width is significantly smaller than the inner width.

[0040] Figure 2a and Figure 2b A very schematic illustration of a flow body 2 with a mechanical joint in a top view is shown. The first mechanical joint 4 is arranged in the central region of the flow body 2 along the span direction 48. It is obvious here that the width w is from the inner width w i Reduced to outer width w o . At the inner position, a second mechanical joint 30 is provided. Here, a second swivel device 40 is arranged in the upper part in the drawing plane. The attachment end 42 of the connecting plate 36 is arranged in the bottom area in the drawing plane. The first swivel device 14 and the second swivel device 40 intersect with an articulation line 50, which corresponds to an articulation for adjusting the alignment of the flow body 2, i.e. for assembling the flow body 2.

[0041] In another outer position 52, which is considered to be the third position 52, a third mechanical joint 53a is provided which is theoretically identical to the second mechanical joint 30. It is obvious that the attachment end 42 of the connection plate 36 will not fit into the flow body 2.

[0042] like Figure 2bAs shown in , a modified third mechanical joint 53b can be used instead. Here, an inverted connecting plate 54 is provided, which has an attachment end 56 and a support end 58 that are arranged inversely compared to the connecting plate 36 of the second mechanical joint 30. Therefore, the connecting plate 54 is attached to the upper end in the drawing plane, and the third rotating device 60 is arranged at the bottom area. The third rotating device 60 determines the third hinge point 61. Therefore, the hinge line 50 can also intersect with the third rotating device 60 by providing an inverted connecting plate 54. This allows a slimmer, longer and / or more curved flow body 2. Therefore, the hinge line 50 can include an angle that is slightly changed relative to the span direction 48.

[0043] For better understanding, Figure 2c Another view of the third mechanical joint 53b is shown. Here, a third support member 55, a third connecting rod 57 and a third support rod 59 are shown. These are connected to each other as in the second mechanical joint 30. However, compared to the second mechanical joint 30, the connecting plate 54 of the third mechanical joint 53b is inverted relative to the third support member 55. Therefore, the connecting plates 36 and 54 connected to the second support rod 38 and the third support rod 59 include different orientations relative to the respective support members 32 and 55, so that the third hinge point 61 is displaced relative to the respective support rod 59 transversely to the main extension axis.

[0044] at last, Figure 3 An aircraft 62 is shown having a wing 64 with a leading edge device 66 and a trailing edge device 68. Exemplarily, one of the leading edge device 66 and the trailing edge device 68 comprises a flow profile 2 according to the above description.

[0045] In addition, it should be noted that "comprising" does not exclude other elements or steps, and "a" or "an" does not exclude plural numbers. In addition, it should be noted that the features or steps described with reference to one of the exemplary embodiments described above can also be used in combination with other features or steps of other exemplary embodiments described above.
