DETAILED DESCRIPTION

An aircraft 1 shown in FIG. 1 has a pair of aircraft wings 2, 3 extending from a fuselage. The wings are identical and only the starboard wing 3 will be described below.

The wing 3 has a leading edge 4 and a trailing edge 5. FIG. 2 is a sectional view of the trailing edge 5 viewed from an outboard direction. The wing 3 comprises a wingbox 6 with an upper cover 7, a lower cover 8, a forward spar 13, and a rear spar 9. The forward spar is not shown in FIG. 2, but it is indicated schematically by a dashed line 13 in FIG. 1.

The forward and rear spars 13, 9 are spaced apart in a fore-aft or chordwise direction indicated in FIG. 3, and the spars extend away from the fuselage in a spanwise outboard direction indicated in FIG. 6.

Referring to FIG. 3, the rear spar 9 has a vertical spar web 10, and a pair of flanges 11, 12 which are attached to the upper and lower covers 7, 8 respectively. The covers 7, 8 each have an overhanging portion behind the rear spar 9. The covers 7, 8 are attached to the forward spar 13 in a similar fashion.

The trailing edge 5 carries a set of spoilers, one of which is labelled 20 in FIG. 1 and shown in FIGS. 2-4. As shown in FIG. 3, the spoiler 20 is pivotally mounted on a spoiler support bracket 21 which is attached to the rear spar 9. The spoiler 20 can be moved between a central low drag position shown in solid lines in FIGS. 2 and 3, a raised position showed in dashed lines in FIG. 2, and a drooped position in which the spoiler is rotated down. In the event of failure of the spoiler deployment mechanism, it may rotate down too far, to an over-travel drooped position shown in dashed lines in FIG. 3.

The trailing edge 5 also carries a pair of flaps, one of which is labelled 30 in FIG. 1 and shown in FIGS. 2 and 4. A deployment mechanism 31 shown in FIGS. 5-7 is configured to deploy the flap 30 between a low drag position shown in FIG. 2, and a high lift position shown in FIG. 4. The deployment mechanism 31 may comprise a flap track which carries the flap 30 and is driven on rollers to deploy the flap 30, or any other kind of deployment mechanism.

A pair of fairings 32, 33 cover the flap deployment mechanism 31. A fixed fairing 32 is attached to the lower cover 8 by tension joints 34 and covers a forward part of the deployment mechanism 31. A movable fairing 33 covers a rear part of the deployment mechanism 31 and moves with the flap 30. These fairings 32, 33 are conventionally known as flap-track fairings.

As shown in FIG. 7, the fixed fairing 32 has a U-shaped profile, with a horizontal base 35 and a pair of vertical side walls 36, 37. Each side wall has an upper edge 36a, 37a which is attached to the lower cover 8 by the tension joints 34; an inner surface 36b, 37b which faces towards the flap deployment mechanism 31; and an outer surface 36c, 37c which faces away from the flap deployment mechanism 31. The outer surfaces 36c, 37c are configured to be exposed to airflow during flight of the aircraft.

The trailing edge 5 also has a set of lower trailing edge panels which fill the gap between the trailing edge of the lower cover 8 and the flap 30. Parts of two of the lower trailing edge panels are shown in FIGS. 5-7: a first lower trailing edge panel 40 on an outboard side of the fairing 32, and a second lower trailing edge panel 41 on an inboard side of the fairing 32. The panels 40, 41 are similar, so only the first panel 40 will be described in detail.

The panel 40 has a leading edge 50 (shown in FIG. 3) which is attached to the wingbox, and a trailing edge 51 opposite the leading edge 50. The leading edge 50 and the trailing edge 51 extend in the spanwise direction, parallel with the rear spar 9.

The leading edge 50 of the panel 40 is attached to the overhanging portion of the lower cover 8 by anchor nut rails 55. Each anchor nut rail 55 carries a line of anchor nuts (not shown) and the leading edge 50 of the panel 40 is attached by passing fasteners through the panel 40, the overhanging portion of the lower cover 8, and the nut rail 55 and then screwing the fasteners into the anchor nuts.

The panel 40 also terminates at each end at a pair of opposite spanwise edges: an inboard edge 52 shown in FIGS. 5-7 at one spanwise end of the panel 40, and an outboard edge (not shown) at an opposite spanwise end of the panel 40.

The panel 40 also has a horizontal upper surface 53 and a horizontal lower surface 54, indicated in FIG. 3. The lower surface 54 is configured to be exposed to airflow during flight of the aircraft. The upper surface 53 defines a plane 56.

The panel 40 is attached to the spoiler support bracket 21 by one or more mid-span support links 60. One of such mid-span support links 60 is shown in FIG. 3. The mid-span support link 60 extends from a first end to a second end. The first end of the mid-span support link 60 is pivotally attached to the lower trailing edge panel 40 at a first pivot joint 61, and the second end of the mid-span support link 60 is pivotally attached to the spoiler support bracket 21 at a second pivot joint 62. The second pivot joint 62 is higher than the first pivot joint 61.

As shown in FIG. 3, the mid-span support link 60 extends in a fore-aft direction in a vertical chordwise plane.

A resilient elastomeric seal member 160, shown in FIG. 8, seals a gap between the upper edge 36a of the side wall 36 of the fairing 32, and the inboard edge 52 of the lower trailing edge panel 40. The seal member 160 can flex to enable the panel 40 to deflect in the spanwise direction, while continuing to seal the gap.

Optionally one or more of the panels 40, 41 are removable, enabling access to the trailing edge 5 for inspection or repair. The panels 40, 41 may be made from a cheaper, thinner and lighter material than the lower cover 8. It is therefore important that the panels 40, 41 do not pick up bending loads as the wing bends during flight. For this reason the support arrangements for the panels 40, 41 (i.e. the mid-span support links 60, the anchor nut rails 55, etc.) may allow the panels 40, 41 to deflect relative to the wingbox 6, particularly in a spanwise direction.

Minimizing space within the trailing edge 5 maximizes fuel tank volume and minimizes the height of the aerofoil section, which maximizes performance. The space available within the trailing edge 5 may therefore be very limited, and so it is important that the support arrangements for the panels 40, 41 take up as little of this space as possible.

The trailing edge 5 also houses various mechanical and electrical systems routings 70 shown in FIGS. 6 and 7 which run along the wing behind the rear spar 9 in a spanwise direction. The support arrangements for the panels 40, 41 must not clash with these routings 70, or any other obstructions.

It is preferable that the support arrangements for the panels 40, 41 enable the routings 70 to be installed or removed as a modular unit by moving them in the fore-aft direction (transverse to their length) rather than by threading the routings 70 along the wing in the spanwise direction (along their length).

Thus, the routings 70 may be installed by moving them in the forward direction into the rear spar, then fitting the mid-span support links 60. This process may be reversed to remove the routings 70: removing the mid-span support links 60 and then removing the routings 70 from the rear spar in the aft direction.

The support arrangements for the panels 40, 41 must also be low profile, in order to maintain kinematic function of all moveables (flaps, spoilers, ailerons etc.).

Another important design constraint for the panels 40, 41, and their support arrangements, is that they can withstand an over-travel failure of the spoiler 20, in which the spoiler 20 rotates down to the over-travel drooped position shown in dashed lines in FIG. 3. Note that in FIG. 3 the spoiler has contacted the trailing edge 51 of the panel 40, which may cause damage to the spoiler 20 and/or to the panel 40.

The trailing edge 5 may also have upper trailing edge panels, located at parts of the wing where there are no spoilers. Such upper trailing edge panels share some of the design constraints of the lower trailing edge panels 40, 41, in particular the requirements that the support arrangements for the upper trailing edge panels take up only a small amount of space, and do not clash with the routings 70, or any other obstructions.

As explained above, a mid-span region of the lower trailing edge panel 40 is supported by one or more mid-span support links 60. In order to avoid flutter caused by the complex airflows at each spanwise end of the panel 40, it is also desirable to provide support for the inboard and outboard edges of the panel 40. To this end, the inboard edge 52 of the lower trailing edge panel 40 is attached to the side wall 36 of the fairing 32 by a panel support arrangement 400 which is illustrated schematically in FIGS. 2-7, and in detail in FIG. 8. The outboard edge of the lower trailing edge panel 41 is attached to the fairing 32 by a similar panel support arrangement which is also illustrated schematically in FIGS. 2-7.

The panel support arrangement 400 shown in FIG. 8 comprises a kinked link 450 which extends from a first end 101 to a second end 102.

The kinked link 450 comprises a first arm 451, a second arm 452, and a corner 453 where the first and second arms meet at an obtuse angle 8. The kinked link 450 may be made from aluminum, or any other suitable material.

The first arm 451 of the kinked link is pivotally attached to the trailing edge panel at the first pivot joint 110, and the second arm 452 of the kinked link is pivotally attached to the fairing at the second pivot joint 120.

The first arm 451 of the kinked link is pivotally attached to the upper surface 53 of the lower trailing edge panel at the first pivot joint 110 adjacent to the inboard edge 52 of the lower trailing edge panel. The second arm 452 of the kinked link is pivotally attached to the inner surface 36b of the side wall 36 of the fairing 32 at the second pivot joint 120 adjacent to the upper edge 36a of the side wall 36 of the fairing 32.

The first arm 451 of the kinked link crosses above the inboard edge 52 of the trailing edge panel. In other words, the first arm 451 intersects with a vertical line 57 extending from the inboard edge 52.

The first arm 451 of the kinked link has a substantially straight center line 451a which extends downwardly to the corner 453; and the second arm 452 of the kinked link has a substantially straight center line 452a which extends downwardly from the corner 453.

As shown in FIG. 8, the upper surface 53 of the lower trailing edge panel 40 is substantially perpendicular to the inner surface 36b of the side wall 36 of the fairing 32.

The first pivot joint 110 comprises a first bracket 111 which protrudes from the upper surface 53 of the lower trailing edge panel adjacent to its inboard edge 52. The second pivot joint 120 comprises a second bracket 121 which protrudes from the inner surface 36b of the side wall 36 of the fairing 32 adjacent to the upper edge 36a of the side wall 36.

The first pivot joint 110 is located above the plane 56 of the panel, and the second pivot joint 120 is located below the plane 56 of the panel.

The first pivot joint 110 is a pin joint which is configured to only permit rotation about a first pivot axis 112, indicated in FIG. 3, which extends in the fore-aft (or chordwise) direction. The second pivot joint 120 is similar—i.e. it is a pin joint which is configured to only permit rotation about a second pivot axis 122, also indicated in FIG. 3, which also extends in the fore-aft or chordwise direction. The second pivot axis 122 is preferably substantially parallel with the first pivot axis 112.

The axis 122 of the second pivot joint 120 is vertically offset below the axis 112 of the first pivot joint 110 by a distance V. The axis 122 of the second pivot joint 120 is also horizontally offset from the axis 112 of the first pivot joint 110 in the spanwise direction by a distance H.

The first bracket 111 protruding from the upper surface of the lower trailing edge panel provides a spoiler stop configured to be contacted by the spoiler 20 in the event of an over-travel failure of the spoiler. The top of the first bracket 111 carries a polytetrafluoroethylene (PTFE) stopper 170 to avoid damage from (or to) the spoiler 20.

The panel support arrangement 400 of FIG. 8 can be assembled as follows. First, the trailing edge panel 40 and the fairing 32 are installed with the kinked link 450 hanging down below the second pivot joint 120. The kinked link 450 is then manually rotated up on the second pivot joint 120 to bring the first end 101 of the link into alignment with a hole in the first bracket 111. The first pivot joint 110 is then assembled by installing a bolt or pin through the hole in the first bracket 111.

The kinked link 450 provides a compact and low-profile design which can connect the brackets 111, 121 around the corner as shown in FIG. 8. The kinked link 450 is preferable to a link which follows a continuous circular curve, because it is more statically determinate.

FIG. 9 show a panel support arrangement 500 according to a second embodiment of the disclosure herein. Most elements of the panel support arrangement 500 are identical to the panel support arrangement 400 of FIG. 8, so only the differences will be described.

The kinked link 450 of FIG. 8 is replaced by a kinked link 550 comprising a first arm 551, a second arm 552, and a corner 553 where the first and second arms meet at an acute angle ϕ. The first arm 551 of the kinked link is pivotally attached to the trailing edge panel at the first pivot joint 110, and the second arm 552 of the kinked link is pivotally attached to the fairing at the second pivot joint 120.

The first arm 551 of the kinked link crosses above the inboard edge 52 of the trailing edge panel.

The first arm 551 of the kinked link has a substantially straight center line 551a which extends upwardly to the corner 553; and the second arm 552 of the kinked link has a substantially straight center line 552a which extends downwardly from the corner 553.

The kinked link 550 provides a less compact design than the kinked link 450. This is out of necessity in order to avoid clashing with an obstruction 560 at the upper edge of the fairing.

The obtuse angle θ of FIG. 8 is preferred to the acute angle ϕ of FIG. 9, because a smaller angle increases the required material properties of the link. Alternatively, the first and second arms may meet at a right angle.

The kinked links 440, 550 may be plain machined aluminum billet, or they may be made from more exotic materials such as steel or titanium, or made from processes such as additive layer manufacturing. The kinked links 450, 550 may also require the use of topology optimization to create an optimized design, best utilizing the high strength material as shown in the kinked link 550 of FIG. 9. The kinked link 450 of FIG. 8 may be solid, whereas the kinked link 550 of FIG. 9 may have a more structurally optimized design formed by a series of struts.

The following alternatives and statements of advantage relate to some or all of the embodiments described above.

Instead of providing a dedicated support structure, such as a fixed trailing edge rib, to support the inboard or outboard edge of the trailing edge panel, the embodiments above use an existing aerodynamic structure (the fairing 32) to support the trailing edge panel via a panel support arrangement 400, 500. The absence of a dedicated support structure reduces weight, and minimizes the space taken up in the trailing edge.

The panel support arrangements 400, 500 enable the routings 70 to be installed or removed as a modular unit by moving the routings 70 in the fore-aft direction (transverse to their length) rather than by threading the routings 70 in a spanwise direction (along their length). The routings 70 can be installed or removed in the fore-aft direction (transverse to their length) without clashing with the panel support arrangements 400, 500. This can be contrasted with the mid-span support links 60 which must not be present during installation or removal of the routings 70.

Thus, the routings 70 may be installed or removed by moving them transverse to their length (i.e. in the fore-aft direction) past the kinked link 450, 550. The low profile of the panel support arrangement ensures that it does not clash with the routings 70 as they are installed or removed.

The embodiments above describe support arrangement 400, 500 for a lower trailing edge panel 40, but in an alternative embodiment a similar kinked link may be provided to support an upper trailing edge panel.

The fairing 32 is attached to the lower cover 8, preferably by one or more tension joints 34. Alternatively, the fairing 32 may be attached to another part of the wingbox, such as the rear spar.

In the embodiments above, the second end of the kinked link is pivotally attached to a flap-track fairing 32 at the second pivot joint. In other embodiments of the disclosure herein, the second end of the kinked link may be pivotally attached to another support structure, such as another type of fairing, or a spoiler support bracket. The support structure may be attached to the rear spar, to the upper or lower cover, or to another part of the wingbox.

In the detailed examples given above, the support structure (fairing 32) is positioned inboard of the inboard edge 52 of the trailing edge panel 40, and the kinked link is pivotally attached to the inboard face of the support structure (the inner face 36b of the fairing 32). The outboard edge of the lower trailing edge panel 41 is attached to the fairing 32 by a similar panel support arrangement. In this case, the support structure (fairing 32) is positioned outboard of the outboard edge of the trailing edge panel 41, and the kinked link is pivotally attached to the outboard face of the support structure.

The second pivot joint may be lower than the first pivot joint. This arrangement results in a low profile kinked link, minimizing the space taken up in the trailing edge by the link and reducing the risk of clash with the routings 70 as the routings 70 are installed or removed.

The first pivot joint and the second pivot joint may be located on first and second sides of the plane 56 of the trailing edge panel. This arrangement results in a low profile kinked link, minimizing the space taken up in the trailing edge by the kinked link and reducing the risk of clash with the routings 70 as the routings 70 are installed or removed.

The first pivot joint may comprise a first bracket 111 which protrudes from the lower trailing edge panel. The use of such a protruding bracket 111 enables the link to be positioned as required.

The second pivot joint may comprise a second bracket 121 which protrudes from the fairing or other support structure. The use of such a protruding bracket 121 enables the link to be positioned as required.

The kinked link may have a center line which extends downwardly along its full length from the first end of the link to the second end of the link. This arrangement results in a low profile link, minimizing the space taken up in the trailing edge by the kinked link and reducing the risk of clash with the routings 70 as the routings 70 are installed or removed.

Orienting the pivot axes 112,122 in the fore-aft (or chordwise direction) enables the panel to deflect easily in the spanwise direction.

A center line of the kinked link may extend in a plane which is parallel with the plane of the spar web, and/or in a vertical spanwise plane. This can be contrasted with the mid-span support link 60, or the lower strut in US2013/0146712, which extend in a vertical chordwise plane and hence may occupy valuable space within the trailing edge.

The kinked link may cross above or below the inboard edge 52 or outboard edge of the trailing edge panel. This enables the kinked link to be positioned close to the inboard or outboard edge of the trailing edge panel.

The second pivot joint may be horizontally offset from the first pivot joint. This enables the panel to deflect easily, particularly in a vertical direction.

The second pivot joint may be horizontally offset from the first pivot joint in the spanwise direction. This makes the link less likely to obstruct the routings 70 within the trailing edge.

The first arm of the kinked link may be pivotally attached to the upper surface 53 of the lower trailing edge panel; and the second arm of the kinked link may be pivotally attached to the inner surface 36b of the fairing. This ensures that the kinked link is not exposed to airflow during flight of the aircraft.

The first end of the kinked link may be pivotally attached to the lower trailing edge panel adjacent to one of the spanwise edges of the trailing edge panel. This enables the kinked link to support the spanwise edge of the trailing edge panel, preventing flutter.

The leading edge 50 of the panel 40 may be secured to the wingbox via the anchor nut rail 55 before the panel support arrangements 400, 500 are installed to secure the inboard and outboard ends of the panel. However, this is not essential, and in other embodiments the order may be reversed: i.e. the panel support arrangements 400, 500 may be installed before the leading edge 50 of the panel 40 is secured to the wingbox.

In the embodiments above the wingbox has a rear spar 9 and a forward spar 13. In other embodiments the wingbox may have more than two spars, or only a rear spar.

Where the word ‘or’ appears this is to be construed to mean ‘and/or’ such that items referred to are not necessarily mutually exclusive and may be used in any appropriate combination.

While at least one example embodiment of the present invention(s) is disclosed herein, it should be understood that modifications, substitutions and alternatives may be apparent to one of ordinary skill in the art and can be made without departing from the scope of this disclosure. This disclosure is intended to cover any adaptations or variations of the example embodiment(s). In addition, in this disclosure, the terms “comprise” or “comprising” do not exclude other elements or steps, the terms “a”, “an” or “one” do not exclude a plural number, and the term “or” means either or both. Furthermore, characteristics or steps which have been described may also be used in combination with other characteristics or steps and in any order unless the disclosure or context suggests otherwise. This disclosure hereby incorporates by reference the complete disclosure of any patent or application from which it claims benefit or priority.
