Specific implementation mode
To keep the purpose, technical scheme and advantage that the present invention is 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
The every other embodiment that member is obtained without creative efforts, shall fall within the protection scope of the present invention.
Anti-corrosion design method at aircaft configuration dead angle of the present invention is described in further details below in conjunction with the accompanying drawings.
As shown in Figures 2 and 3, Anti-corrosion design method at a kind of aircaft configuration dead angle of the invention, for prevent ponding,
Hydrops corrodes at aircaft configuration dead angle, includes the following steps:
Nonabsorbent material is processed into filling cushion block 1 by step 1 first, and the shape of filling cushion block 1 is aircaft configuration dead angle
The planform of the filling region 2 at place, as shown in Fig. 2, the filling cushion block 1 only needs to be installed in place, it is not necessary to correction of the flank shape, compatible degree
Height, the filling cushion block 1 preferentially select the plastic foamboard of lightweight, plastic foamboard to be blocked with traditional fluid sealant or putty
Mode is compared, and more construction weight is saved.
Step 2, be subsequently filled cushion block 1 carry out surfacecti proteon processing, surfacecti proteon processing include surface coating sealant with
Situations such as surface peening, surface coating sealant is for preventing the oxidation of filling cushion block 1, corroding, surface peening is for preventing
It tramples or weight falls situations such as caused matrix destroys.After filling cushion block 1 has carried out surfacecti proteon processing, cushion block is filled
1 surface can adhere to layer of surface protective layer 6, improve filling 1 resistance to corrosion of cushion block, as shown in Figure 3.Wherein, in filling cushion block 1
It, can be according to actual needs in 1 surface of filling cushion block design drainage channel for guiding ponding, hydrops before carrying out surfacecti proteon processing
Discharge avoids the remaining of ponding, hydrops, reduces the corrosion at aircaft configuration dead angle.
Filling cushion block 1 is then fixedly installed in filling region 2, due to processing, installing equal error, causes by step 3
There are gaps between filling region 2 and filling cushion block 1, are carried out using gap of the sealant 3 between filling region 2 and filling cushion block 1
Filling.Wherein, filling cushion block 1 can be connect with filling region 2 by connectors such as bolt, rivets, can also use binder
Bonding, can play will fill in the filling region 2 that cushion block 1 is installed at aircaft configuration dead angle.
Secondly step 4 is filled 1 surface of cushion block and is closed with wrapping layer, carries out second of surfacecti proteon, further prevent accumulating
The corrosion of water, hydrops, and using rubber liquid stick by wrapping layer be bonded at aircaft configuration dead angle with filling cushion block 1 it is adjacent
Region, as shown in figure 3, the wrapping layer preferentially selects dirigible fabric 5, dirigible fabric 5 has a preferable water proofing property, higher elasticity and
Intensity, while there is stronger thermal stability and wearability, wrapping layer can also use sheet metal, but it should be noted that make
When with sheet metal, first bonded metal thin plate, then it is connected by screw bolts filling cushion block 1 and filling region 2.
Step 5, due to being provided with filling cushion block 1 in the filling region 2 at aircaft configuration dead angle so that hydrops liquid level carries
Height, in empty band, suitably highly place's setting osculum 4, ponding, hydrops by product on 1 surface of filling cushion block pass through row for selection
Water hole 4 is discharged, and avoids corroding.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, all answer by the change or replacement that can be readily occurred in
It is included within the scope of the present invention.Therefore, protection scope of the present invention should be with the scope of the claims
It is accurate.
