Description
Technical field
The present invention relates to technical field of aircraft structure design, in particular to aircraft target ship docking structure.
Background technique
Existing technique for aircraft composite siding and metal wallboard generally pass through the double lapping plate docking of uniform thickness.Lapping plate extend to etc.
Thickness design causes first row fastener load excessive；Metal wallboard and Composite Panels are identical in docking area thickness, due to
The nail hole of Composite Panels squeezes allowable value and is lower than metal wallboard, causes metal wallboard thickness and weight big；Inside and outside lapping plate
Uniform strength design a possibility that cracking two sides it is suitable, be unfavorable for structure inspection maintenance.
Summary of the invention
To overcome above-mentioned at least one defect of the existing technology, the present invention provides a kind of aircraft target ships to binding
Structure, including Composite Panels, metal wallboard, docking costal margin item and docking band plate, Composite Panels and metal wallboard are logical
It crosses fastener to be fixed between docking costal margin item and docking band plate, there are between siding between Composite Panels and metal wallboard
Gap, the thickness for docking costal margin item is thinning from the siding gap location to two sides staged, and the thickness of band plate is docked in same section
Less than the thickness of docking costal margin item.
Preferably, the thickness of metal wallboard is less than the thickness of Composite Panels, and docking costal margin item and docking band plate are in institute
State siding gap location inflection.
Preferably, Composite Panels are fixed between docking costal margin item and docking band plate by four row's fasteners, metal
Siding is fixed between docking costal margin item and docking band plate by three row's fasteners.
Aircraft target ship docking structure provided by the invention, has the following beneficial effects:
1, inside lapping plate extends the nail load that fastener is reduced to Varying-thickness, and it is uneven to solve fastener load distribution
The problem of；
2, double lapping plates inflection at metal wallboard and Composite Panels docking, convenient for two side wall panels, uniform thickness is not docked,
Construction weight is alleviated, solves the problems, such as that construction weight is big；
3, lateral overlap plate thickness is less than inside overlap joint plate thickness, appears in crackle on lateral overlap plate, improving can
Inspection property, solves the problems, such as that maintainability is bad.

Specific embodiment
To keep the purposes, technical schemes and advantages of the invention implemented clearer, below in conjunction in the embodiment of the present invention
Attached drawing, technical solution in the embodiment of the present invention is further described in more detail.In the accompanying drawings, identical from beginning to end or class
As label indicate same or similar element or element with the same or similar functions.Described embodiment is the present invention
A part of the embodiment, instead of all the embodiments.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to use
It is of the invention in explaining, and be not considered as limiting the invention.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be understood that, term " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is based on attached drawing institute
The orientation or positional relationship shown, is merely for convenience of description of the present invention and simplification of the description, rather than the dress of indication or suggestion meaning
It sets or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as protecting the present invention
The limitation of range.
Below by specific embodiment, the present invention is described in further detail.
Specific embodiment:
The present invention provides a kind of aircraft target ship docking structures, for the connection at aircraft wing, as shown in Figure 1 to Figure 3,
Including Composite Panels 1, metal wallboard 2, docking costal margin item 3 and docking band plate 4, it is preferred that docking costal margin item 3 and jointing strip
Plate 4 is metal machine-made spares and material is aluminium alloy, docking costal margin item 3 and docking 4 groups of lapping plates in pairs of band plate, composite wood
Material siding 1 and metal wallboard 2 are fixed between docking costal margin item 3 and docking band plate 4 by fastener 5, and fastener 5 is preferably adopted
With bolt, in the present embodiment, Composite Panels 1 by four row's fasteners 5 be fixed on docking costal margin item 3 and docking band plate 4 it
Between, metal wallboard 2 is fixed between docking costal margin item 3 and docking band plate 4 by three row's fasteners 5；
There are siding gap between Composite Panels 1 and metal wallboard 2, the thickness of costal margin item 3 is docked from the siding
Gap location is thinning to two sides staged, i.e., docking costal margin item 3 thickness extend it is thinning to level-one level-one, with reduce outside fastener
5 load, and the thickness that band plate 4 is docked in same section is less than the thickness of docking costal margin item 3, makes the docking band plate positioned at outside
Semi-finals degree is weaker than the docking costal margin item 3 positioned inside, appears in crackle on the docking band plate 4 on the outside of wing, is easy to examine
It looks into, i.e., the sum of docking costal margin item 3 and the thickness for docking band plate 4 are constant in same section, only thickness distribution between the two
Ratio is different, this is not equal strength design, it is preferred that docking costal margin item 3 is thinned substantially with a thickness of 4mm~8mm at both ends as 3mm
~5mm；Dock band plate 4 with a thickness of 3mm~4mm；
In the present embodiment, the thickness of metal wallboard 2 is less than the thickness of Composite Panels 1, docks costal margin item 3 and jointing strip
In the siding gap location inflection, inflection makes rib edge strip 3 and docks the change of distance between band plate 4 plate 4, compound to realize
The docking of the not uniform thickness of material siding 1 and metal wallboard 2, meets Composite Panels 1 and metal wallboard 2 thickness is different but can be with
It docks costal margin item 3 and docks the demand of the fitting contact of band plate 4, it is preferred that docking costal margin item 3 and docking band plate 4 are in metal wallboard 2
Place reduces the metal wallboard 2 of docking area compared with 1 thickness of Composite Panels respectively to 2 inflection 1mm~2mm of metal wallboard.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by those familiar with the art, all answers
It is included within the scope of the present invention.Therefore, protection scope of the present invention should be with the scope of protection of the claims
It is quasi-.
