The configurations described herein relate to a joint for composite wings. The joint may be for a lower side-of-body joint of an aircraft.
2. Description of the Related Art
Bolted side-of-body joints may be used to connect wings to the fuselage of an aircraft. One design of a side-of-body joint 200 presently used to connect a wing to a fuselage is shown in FIG. 12. The joint 200 includes a double plus chord 210 that includes a vertical portion 211, an upper inboard portion 212, a lower inboard portion 213, an upper outboard portion 214, and a lower outboard portion 215. An inboard wing panel assembly 220 is connected to the inboard side of the double plus chord 210 and an outboard wing panel assembly 230 is connected to the outboard side of the double plus chord 210.
The inboard wing panel assembly 220 includes a stringer 260 connected to an inboard wing skin 240 and the outboard wing panel assembly 230 includes a stringer 260 connected to an outboard wing skin 250. The stringer 260 includes a base flange 261 on the bottom of the stringer 260 and a cap 263 located on the top with a web 262 connecting the cap 263 to the base flange 261. The base flange 261 of the stringer 260 is connected to the inboard wing skin 240. The base flange 261 may be bonded to the inboard wing skin 240.
The cap 263 is connected to the upper inboard portion 212 of the double plus chord 210 by a plurality of fasteners 281. A portion of the web 262 and base flange 261 of the stringer 260 is cut so that base flange 261 of the stringer 260 does not overlap the lower inboard portion 213 of the double plus chord 210. A radius filler plate 291 is positioned above the base flange 261. Fasteners 290 connect the radius filler plate 291 to the base flange 261 and the inboard wing skin 240, which clamp the inboard wing skin 240 and base flange 261 to form a crack arrestment mechanism. Only the inboard wing skin 240 of the inboard wing panel assembly 220 is positioned below the lower inboard portion 213 of the double plus chord 210. The inboard wing skin 240 is positioned between the lower inboard portion 213 of the double plus chord 210 and a splice plate 270. Fasteners 280 connect the splice plate 270 to the lower inboard portion 213 of the double plus chord 210 securing the inboard wing skin 240 to the joint 200.
The outboard wing panel assembly 230 is constructed the same way as the inboard wing panel assembly 220. Fasteners 281 are used to connect the cap 263 of the stringer 260 to the upper outboard portion 214 of the double plus chord 210. Fasteners 280 connect the outboard wing skin 250 to the splice plate 270 and the lower outboard portion 215 of the double plus chord 210. The connection of one portion of a wing panel assembly to a first portion of a joint, and the connection of a second portion of a wing panel assembly to a second portion of the joint may result in differing forces to be applied to the different portions of the assembly.

DETAILED DESCRIPTION
FIG. 1 shows a configuration of a wing joint 1. The wing joint 1 includes a first clamp plate 10 and a second clamp plate 15 used together to secure an inboard wing panel assembly 20 and an outboard wing panel assembly 30. The first clamp plate 10 may be a T-chord and the second clamp plate may be a splice plate. Hereinafter, the first clamp plate will be referred to as a T-chord 10 and the second clamp plate will be referred to as a splice plate 15. The T-chord 10 includes a vertical portion 11, an inboard portion 12, and an outboard portion 13. The splice plate 15 includes an inboard portion 16 and an outboard portion 17. The T-chord 10 and splice plate 15 are used to connect together an inboard wing panel assembly 20 and an outboard wing panel assembly 30.
The inboard wing panel assembly 20 is comprised of an inboard wing skin 40 and a stringer 60. The inboard wing skin 40 and the stringer 60 may both be comprised of a composite material, which may be comprised of multiple layers of a material bonded and/or cured together. The material may be comprised of various materials used in the formation of composite materials. One example of such material is carbon fiber reinforced plastic. Likewise, the outboard wing panel assembly 30 is comprised of an outboard wing skin 50 and a stringer 60. As discussed above, the outboard wing skin 50 and the stringer 60 may also be co-bonded or co-cured. The stringer 60 used may be various stringers used to strengthen composite parts, such as an I stringer or a blade stringer.
The stringer 60 is bonded to the wing skin 40, 50 to form a wing panel assembly 20, 30. The stringer 60 and wing skin 40, 50 may be co-cured so as to form a bond between the two components. After the wing panel assemblies 20, 30 are formed, the wing panel assemblies 20, may then be connected together with T-chord 10 and splice plate 15 to form a wing joint 1. The stringer 60 may include a base flange 61 and a web 62. If the stringer 60 is an I stringer, as shown in FIG. 8, then the stringer 60 may include a cap 63. The cap 63 and web 62 of the stringer 60 may be trimmed so that only the base flange 61 of the stringer 60 runs out into the wing joint 1. The cap 63 and web 62 may be trimmed to expose a noodle 64 or a plurality of noodles as discussed below.
An end portion of the inboard wing panel assembly 20 may be positioned between the inboard portion 12 of the T-chord 10 and the inboard portion 16 of the splice plate 15. As discussed above, the web 62 and cap 63 may be been trimmed so that only the base flange 61 of the stringer 60, which is bonded to the inboard wing skin 40, is positioned between the T-chord 10 and the splice plate 15. As discussed below, the stringer 60 may also include an exposed noodle(s) 64 that is also positioned between the T-chord 10 and the splice plate 15. A plurality of fasteners 80 connect the inboard portion 12 of the T-chord 10 to the inboard portion 16 of the splice plate 15, securing the inboard wing panel assembly 20 to the wing joint 1. Likewise, the outboard wing panel assembly 30 is connected to the outboard portion 13 of the T-chord 10 and the outboard portion 17 of the splice plate 15.
FIG. 2 shows a partial cross-section of a wing panel assembly 20 that includes a stringer 60 bonded to a wing skin 40. The web 62 and cap 63 have been trimmed to expose a noodle 64 on the base flange 61 of the stringer 60. Noodles 64 are typically unidirectional fibers that are used to fill a junction between portions of a stringer 60 as shown in FIG. 8. For example, an I stringer may be comprised of two “c” shaped brackets connected together back to back. A void may exist at both the top and bottom junctions where the back of the brackets meet. A noodle 64, which may be a unidirectional fiber, may be used to fill the void. The noodle 64 may be comprised of various materials, such as unidirectional carbon fiber reinforced plastic, laminated carbon fiber reinforced plastic, or glass fiber reinforced plastic. As shown in FIG. 2, the noodle 64 may not be flush with the base flange 61. If the noodle 64 is not flush with the base flange 61, the T-chord 10 or stringer 60 may be modified to accommodate the non-flush noodle 64, as discussed below.
FIG. 3 is a schematic showing the potential forces that may be applied to the wing joint 1. As both the inboard wing skin 40 and base flange 61 are secured to the T-chord 10 and the splice plate 15 at the same interface, the same tension force is applied to both components equally as shown by arrow 85. Further, the tension forces (arrows 90) on both the T-chord 10 and splice plate 15 are substantially equal and in the same direction, because the two components provide a single interface for capturing the wing panel assembly 20 in comparison to the multiple interfaces of the double plus chord 210 shown in FIG. 12.
FIG. 4 shows a portion of a stringer 60 that may be connected to the wing joint 1 of the present disclosure. The stringer 60 includes a base flange 61 and web 62 trimmed to expose a noodle 64. The stringer 60 may include a web and cap run out 65 where the trimmed web 62 interfaces with the exposed noodle 64. As discussed above, the noodle 64 may be comprised of unidirectional fiber and may fill a void between two interfaces in the stringer 60.
FIG. 5A and FIG. 5B show a configuration of T-chord 10 that may be used in the wing joint 1. The T-chord 10 may include a scalloped or cutout feature 14 that permits the web 62 of the stringer 60, such as the blade of a blade stringer, to extend between one or more rows of fasteners 80 that connect the T-chord 10 to a spice plate 15. The T-chord 10 may include a plurality of rows of fasteners 80. For example, the T-chord 10 may include a first row of fasteners 81, a second row of fasteners 82, and a third row of fasteners 83. The cutout feature 14 may protrude so it crosses the first and second rows of fasteners 81, 82 as shown in FIG. 5A and FIG. 5B. The T-chord 10 may include a plurality of cutout features 14. The use of the cutout feature 14 of the T-chord 10 may permit the stringer 60 to be more robust by permitting a longer length of web 62 along the stringer 60. The number and orientation of the cutout features 14 is for illustrative purposes only. The configuration, depth, and location of the cutout features 14, as well as the number of rows and configuration of fasteners, may be varied as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure. For example, even the individual length of the cutout features 14 may be varied within a single T-chord 10.
FIG. 6 shows a partial cross-section of a configuration of T-chord 10 that includes at least one groove 18 on the bottom side of the inboard portion 12 of the T-chord 10. The groove 18 may be adapted to accommodate a non-flush noodle 64 present on the wing panel assemblies 20, 30. The insertion of the non-flush noodle 64 into the groove 18 may enable the interface between the T-chord 10 and wing panel assembly 20 to be flush. The T-chord 10 may include a plurality of grooves 18 in the bottom of both the inboard 12 and outboard 13 portions to accommodate a plurality of exposed noodles 64.
FIG. 7 shows a configuration of a trimmed stringer 60 that includes shims 67 to accommodate for non-flush noodles 64. The shim(s) 67 are located adjacent to the non-flush noodle 64 between the base flange 61 and the T-chord 10. The shims 67 fill the gaps between the wing panel assembly 20, 30 and the T-chord 10 due to the noodle 64 being non-flush. The shims 67 are shown for illustrative purposes only as the shape, number, and configuration of the shims 67 may be varied, as would be appreciated by one of ordinary skill in the art having the benefit of this disclosure.
FIG. 8 shows a cross-section of an I stringer 60 bonded to a wing skin 40. The I stringer 60 includes a base flange 61, a web 62, and a cap 63. For co-bonded wing panels, the base flange 61 may include a base flange charge 66, which is not required for co-cured wing panels. The cap 63 may include a cap charge 68 for both co-bonded and co-cured wing panels. As shown, noodles 64 fill the gap between the web 62 and the cap 63 as well as the gap between the web 62 and the base flange 61. As discussed above, the cap 63 and web 62 may be trimmed on one end of the stringer 60 to expose the noodle 64. The exposed noodle 64 and base flange 61 may then interface with the bottom of the T-chord 10 when the wing panel assembly 20, the stringer 60 bonded to the wing skin 40, is secured to the T-chord 10 and the splice plate 15, as discussed above.
FIG. 9 shows a cross-section of a blade stringer 60 that includes additional plies or layers, referred to herein as sacrificial plies 69, that permit the removal of material from the stringer 60 while maintaining the desired structural integrity of the stringer 60. As discussed above, the web 62 of the stringer 60 is trimmed to expose the noodle 64 and provide an interface between the stringer 60 and the T-chord 10. Upon exposing the noodle 64, the noodle 64 may not be flush with the base flange 61. To accommodate for a potential non-flush noodle 64, sacrificial plies 69 are added to the web 62 and base flange 61 of the stringer 60. The sacrificial plies permit the web 62 and base flange 61 to be trimmed down to a level 70, which is flush with the exposed noodle 64 while retaining a thickness of material of the stringer 60 that maintains its intended structural integrity.
Referring more particularly to the drawings, configurations of the disclosure may be described in the context of an aircraft manufacturing and service method 100 as shown in FIG. 10 and an aircraft 102 as shown in FIG. 11. During pre-production, exemplary method 100 may include specification and design 104 of the aircraft 102 and material procurement 106. During production, component and subassembly manufacturing 108 and system integration 110 of the aircraft 102 takes place. Thereafter, the aircraft 102 may go through certification and delivery 112 in order to be placed in service 114. While in service 114 by a customer, the aircraft 102 is scheduled for routine maintenance and service 116 (which may also include modification, reconfiguration, refurbishment, and so on).
Each of the processes of exemplary method 100 may be performed or carried out by a system integrator, a third party, and/or an operator (e.g., a customer).
