Detailed description of the invention
Clearer for the purpose making the present invention implement, technical scheme and advantage, below in conjunction with in the embodiment of the present invention
Accompanying drawing, the technical scheme in the embodiment of the present invention is further described in more detail.In the accompanying drawings, the most identical or class
As label represent same or similar element or there is the element of same or like function.Described embodiment is the present invention
A part of embodiment rather than whole embodiments.The embodiment described below with reference to accompanying drawing is exemplary, it is intended to use
In explaining the present invention, and it is not considered as limiting the invention.Based on the embodiment in the present invention, ordinary skill people
The every other embodiment that member is obtained under not making creative work premise, broadly falls into the scope of protection of the invention.
Below in conjunction with the accompanying drawings Anti-corrosion design method at aircaft configuration dead angle of the present invention is described in further details.
As shown in Figures 2 and 3, Anti-corrosion design method at a kind of aircaft configuration dead angle of the present invention, be used for preventing hydrops,
At hydrops corrosion aircaft configuration dead angle, comprise the steps:
Step one, is first processed into filling cushion block 1 by nonabsorbent material, and that fills cushion block 1 is shaped as aircaft configuration dead angle
The planform filling region 2 in place, as in figure 2 it is shown, this filling cushion block 1 only needs installation to put in place, it is not necessary to correction of the flank shape, agrees with
Degree height, this filling cushion block 1 preferentially selects the plastic foamboard of lightweight, plastic foamboard and traditional fluid sealant or putty closure
Mode compare, save more construction weight.
Step 2, is subsequently filled cushion block 1 and carries out surfacecti proteon process, surfacecti proteon process include surface-coated sealant and
Surface peening, surface-coated sealant is used for preventing filling that cushion block 1 aoxidizes, the situation such as corrosion occurs, and surface peening is used for preventing
Trample or the weight situations such as the matrix destruction that causes that drop occur.After filling cushion block 1 has carried out surfacecti proteon process, fill cushion block
Layer of surface overcoat 6 can be adhered in 1 surface, improves and fills cushion block 1 resistance to corrosion, as shown in Figure 3.Wherein, cushion block 1 is being filled
Before carrying out surfacecti proteon process, can be used for guiding hydrops, hydrops at filling cushion block 1 surface designing and arranging water passage according to actual needs
Discharge, it is to avoid hydrops, the remaining of hydrops, reduce the corrosion at aircaft configuration dead angle.
Step 3, is then fixedly installed to filling cushion block 1 fill in region 2, due to processing, installs equal error, cause
Fill and leave gap between region 2 and filling cushion block 1, use sealant 3 that the gap filled between region 2 and filling cushion block 1 is carried out
Fill.Wherein, fill cushion block 1 to be connected by the connector such as bolt, rivet with filling region 2, it is also possible to use binding agent
Bonding, can play in the filling region 2 that will fill during cushion block 1 is installed at aircaft configuration dead angle.
Step 4, secondly fills cushion block 1 surface integument and closes, carry out second time surfacecti proteon, prevent from further amassing
Water, the corrosion of hydrops, and in using rubber liquid stick to be bonded at aircaft configuration dead angle by integument with fill cushion block 1 phase
Adjacent region, as it is shown on figure 3, this integument preferentially selects dirigible fabric 5, dirigible fabric 5 to have preferable water proofing property, higher elasticity
And intensity, there is stronger heat stability and wearability simultaneously, integument can also use sheet metal, but it should be noted that
When using sheet metal, first bonded metal thin plate, then filling cushion block with bolts 1 with fill region 2.
Step 5, owing to being provided with filling cushion block 1 so that hydrops liquid level in the filling region 2 at aircaft configuration dead angle
Improve, select to arrange osculum 4 at empty band suitably height, pass through amassing at the filling hydrops on cushion block 1 surface, hydrops
Osculum 4 is discharged, it is to avoid corrosion.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, and any
Those familiar with the art in the technical scope that the invention discloses, the change that can readily occur in or replacement, all answer
Contain within protection scope of the present invention.Therefore, protection scope of the present invention should be with described scope of the claims
Accurate.
