Problems solved by technology

However, since corrosion does not only occur on the outer surface of the fairing, corrosion may still occur on the inner wall of the leak hole
[0006] However, in the prior art, it is impossible to cover the smooth water retaining cloth on the inner wall of the water leakage hole and the outside of the water leakage hole at the same time.
For example, if you first ensure that the water retaining cloth on the inner wall of the leak hole is flat, then when smoothing the water retaining cloth on the outside of the leak hole, the water retaining cloth just glued to the inner wall of the leak hole will be peeled off due to external force, so that the water retaining cloth and the inner wa

Embodiment 1

[0033] This embodiment discloses a method for edge sealing a water leakage hole of a fairing, which includes a guide rod 1 and a water retaining cloth 2; including the following steps:

[0034] (1) Cover the side of the water retaining cloth 2 coated with the adhesive 3 on the outside of the leak hole; in order to prevent the adhesive 3 from blocking the leak hole and causing accumulated water to not flow out of the leak hole smoothly, apply the adhesive 3 , reserve a non-adhesive-coated area on the water retaining cloth 2, and this area stretches into the deepest part of the water leakage hole. In addition, the present invention can also first coat the adhesive agent on the inner wall of the water leakage hole and the outer periphery of the water leakage hole, and then cover the outside of the water leakage hole with the water retaining cloth. Since there are gaps in the water retaining cloth, in order to further ensure that the accumulated water can flow out of the non-adhes...

Embodiment 2

[0045] This embodiment discloses an edge-sealing structure for a water leakage hole of a fairing, which includes a water leakage hole opened on the fairing, and the outside of the water leakage hole is covered with a water-retaining cloth; the water-retaining cloth is glued to the water leakage hole evenly on the outer perimeter and on the inner wall.

Embodiment 3

[0047] This embodiment discloses an edge-sealing structure for a water leakage hole of a fairing, which includes a water leakage hole opened on the fairing, and the outer side of the water leakage hole is covered with a glass fiber woven cloth; the glass fiber woven cloth is smoothed by epoxy resin glue Glue it on the periphery and the inner wall of the outside of the leakage hole.

Abstract

The invention discloses an edge sealing structure for a fairing water leakage hole. The edge sealing structure comprises the water leakage hole formed in a fairing. The outer side of the water leakage hole is covered with water retaining cloth. The water retaining cloth is smoothly glued on the periphery and the inner wall of the outer side of the water leakage hole. The invention further discloses an edge sealing method for the fairing water leakage hole. The edge sealing structure and method for the fairing water leakage hole have the advantages that the corrosion phenomenon on the periphery and the inner wall of the water leakage hole is rapidly and efficiently prevented, and the binding fastness is high.

Description

technical field [0001] The invention relates to the technical field of fairings, in particular to an edge-sealing structure and an edge-sealing method for a water leakage hole of a fairing. Background technique [0002] Fairings are used to protect satellites and other payloads from harmful environments such as aerodynamics, aerodynamic heating, and acoustic vibrations. [0003] The fairing is exposed to the outside air for a long time, and a certain amount of accumulated water will be generated inside it. The accumulated water will accumulate in the fairing for a long time, which will corrode the load or the fairing itself. Therefore, the prior art often realizes the timely outflow of stagnant water by providing leak holes on the fairing. [0004] Since the surface of many fairings is made of carbon fiber composite materials, when the accumulated water flows out, it will be immersed in the carbon fiber composite material, destroying the adhesion between the resin layer and...
