Definitions
- This invention relates to a method of preparing a part for assembly to form an aircraft component and more particularly to a method that involves the use of shims.
- the invention also relates to an aircraft component assembled by such a method.
- An example where such issues arise is in the assembly of a wing skin to rib feet to form a wing-box of an aircraft.
- the wing skin is manufactured in a desired shape and is then brought into position against the sub components (rib and spars, for example) of the underlying structure of the wing-box to which the wing skin is to be secured.
- That underlying structure has outwardly projecting rib feet on which respective parts of the inner surface of the wing skin are required to rest so that fasteners can be inserted through the wing skin and the rib feet to secure them together.
- the external profile of the wing skin is important in terms of the aerodynamic performance of the aircraft and a strong connection between the wing skin and the rib feet is also important in terms of the structural strength of the wing-box.
- a first approach is simply to deform the wing skin by the small amount necessary to bring the other rib feet into contact with the wing skin.
- An approach of that kind results in a distortion of the external profile of the wing skin, which may adversely affect the aerodynamic performance of the wing, and in the introduction of additional internal stresses into the wing- box, which may adversely affect the structural strength of the wing.
- a second approach involving altering the dimensions -of the underlying structure or the wing skin may be adopted.
- There are various ways in which that may be done including fettling the rib feet, adding material to the wing skin or applying a shim to the rib feet.
- liquid shimming techniques are employed.
- a solid shim of appropriate thickness is bonded to a part and a liquid shim (a substance that is applied as a liquid but cures to a solid) is applied over the solid shim.
- a second technique uses a liquid shim only and is used mainly for smaller gaps.
- a third technique involves first applying a liquid shim to a part and then applying a solid shim over the liquid shim. After the shim has been applied the parts to be joined are brought together.
- a method of preparing a first part for assembly to form an aircraft component by applying a shim to a first surface of the first part, the method comprising the steps of: placing the first surface of the part adjacent to a second surface of a second part, inserting a solid shim into a gap between the first and second surfaces and holding the shim in the inserted position, and subsequently introducing a liquid shim through the first part into a region between the first part and the solid shim.
- the method may further include the step of separating the first and second parts with the solid shim mounted on the first part and with the liquid shim between the solid shim and the first surface of the first part.
- the first part is assembled next to the second part before the liquid shim is applied. That assembly can therefore take a relatively long time without any risk of liquid shim curing (since it has not at that stage been applied) .
- the first part has one or more passageways extending from the first surface through the thickness of the first part for allowing the introduction of the liquid shim through the first part, which may for example be a rib foot.
- the number of passageways may be chosen to allow liquid shim to spread over the first surface of the first part to the extent required.
- the first part may be of metal and in that case the solid shim is preferably of metal.
- the first part may be of composite material and in that case the solid shim is preferably of composite material.
- the solid shim is preferably held in the inserted position by temporarily fixing the solid shim to the second part.
- the method preferably further includes the step of subsequently detaching the solid shim from the second part.
- adhesive tape for example, masking tape
- the shim preferably includes one or more outwardly projecting tabs, which are preferably detachable and by which the shim is temporarily fixed to the second part.
- two tabs may be provided extending from opposite ends of the oval. The tabs may be fixed as integral parts of the solid shim but may be detachable for example by breaking them off, cutting or the like.
- the liquid shim is preferably introduced by injecting it under pressure into the passageway in the first part.
- the liquid shim is then caused to spread out within the region between the solid shim and the first part.
- Any liquid shim that exudes from the periphery of the solid shim can be removed.
- the second part may not be the part to which the first part is to be joined in the final assembly but may just be a part that replicates precisely the shape of the surface adjacent to the solid shims in the final assembly, but it is preferred that it is.
- a further liquid shim may be provided between the solid shim and the second part when the parts are subsequently joined.
- the first part may have a multiplicity of first surfaces to each of which a respective shim is applied by a method as defined above.
- the first part may for example include a plurality of rib feet.
- the invention is especially relevant to the assembly of a wing-box.
- a method of preparing a first part for assembly to form an aircraft component by applying a shim to a first surface of the first part, the method comprising the sequential steps of: placing a solid shim adjacent to the first surface of the first part, introducing a liquid shim into a region between the first surface of the first part and the solid shim, and assembling the first part to a further part, with the solid shim mounted over the first surface of the first part, with the liquid shim between the solid shim and the first surface of the first part, and with the solid shim adjacent to the further part.
- the invention also provides a method of assembling parts to form an aircraft component, the method including a method of preparing a first part for assembly as defined above.
- the present invention further provides an aircraft component including a first part having a first surface, a solid shim mounted over the first surface, cured liquid shim between the solid shim and the first surface, the cured liquid shim also being present in one or more passageways extending from the first surface of the first part through the first part. Also the present invention provides an aircraft component that has been assembled by a method as defined above .
- Fig. 1 is a plan view of a solid shim for use in assembling two parts according to a first embodiment of the invention
- Fig. 2 is a plan view of a rib foot on which two solid shims of Fig. 1 are to be mounted;
- Fig. 3A is a schematic sectional side view of a rib foot
- Fig. 3B is a schematic sectional side view of the part of the rib foot shown in Fig. 3A, with a cover positioned adjacent to, but spaced from, the rib foot
- Fig. 3C is a schematic sectional side view of the assembly shown in Fig. 3B with a solid shim inserted into the gap between the cover and the rib foot,
- Fig. 3D is a schematic sectional side view of the assembly shown in Fig. 3C with liquid shim material injected between the solid shim and the rib foot according to the first embodiment of the invention
- Fig. 3E is a schematic sectional side view of the assembly shown in Fig. 3D with the cover removed, and
- Fig. 4 is a plan view of a forward flap track attachment to which liquid and solid shim is applied according to a second embodiment of the invention.
- the solid shim 1 shown in Fig. 1 is of a shape suitable for application to one end of a rib foot.
- it is made of glass fibre and has two tabs 2 each 30 mm long and 5 mm wide with a narrowed portion 3 where they join the main part of the shim.
- the shim of this particular example is of generally oval shape with the tabs 2 connected at opposite ends of the oval .
- Fig. 2 shows the shape of the end face of a rib foot 4.
- the foot 4 is to receive two shims 1, one over each of the shaded areas.
- the crosses in Fig. 2 mark the positions of four passageways 5 through the foot 4 (see Fig. 3A) .
- FIG. 3A this is a sectional view of the rib foot 4 along the lines A-A in Fig. 2 and therefore intersecting two of the passageways 5. This drawing shows the rib foot at the beginning of the procedure .
- jigs not shown
- the spacing of the parts is exaggerated for ease of illustration.
- Fig. 3C are inserted between the rib foot 4 and the wing skin ⁇ , as shown in Fig. 3C.
- Two shims 1 are received on each rib foot 4 with each shim overlying one of the areas shaded in Fig. 2. It will be understood that although only one rib foot is shown in the drawings a typical rib of an aircraft wing-box includes a multiplicity of rib feet.
- the shims 1 are temporarily fixed to the wing skin 6 by masking tape (not shown) which is placed over the tabs 2 and releasably fixed to the wing skin 6.
- a liquid shim 7 is injected through each of the passageways 5. That injection presses the solid shim 1 hard against the wing skin 6 and creates a layer of liquid shim between the rib foot 4 and the solid shim 1.
- the liquid shim spreads out radially from the passageways 5 and injection of the liquid shim is continued until all of the areas shaded in Fig. 2 are full of liquid shim. Any surplus liquid shim that exudes outwardly of the solid shim 1 is removed with a spatula.
- the passageways 5 remain full of liquid shim. This stage of the procedure is illustrated in Fig. 3D.
- the liquid shim assumes a thickness which is optimised for the precise location of the wing skin in relation to the rib feet.
- the wing skin 6 is separated from the rib feet 4 carrying the solid shims 1. During that removal the adhesive tape becomes detached from either the wing skin 6 or the tabs 2 and can be removed entirely. The tabs 2 are then removed with a pair of end cutting snips leaving the rib foot 4 in - li ⁇
- Figs. 3A to 3E for ease of illustration no variation is shown in the spacing of the rib foot and the cover, and all the surfaces are shown as flat, but it will be understood that commonly there will be small variations which are accommodated by a variation in the thickness of each shim 1 and/or by a variation in the thickness of the layer of liquid shim 7.
- the thickness of the solid shim 1 and the thickness of the layer of liquid shim 7 are each in the range of 0.3 to 1.0 mm.
- Fig. 4 shows a forward flap track attachment 10 which has eight through passageways marked by crosses so that liquid shim is provided over all but a central unshaded region 11.
- the solid shim according to the presently described example is constructed from glass fibre, it is to be understood that other shim materials may be suitable and will generally depend on the application and the materials from which the first and second parts are fabricated.
