Description

Technical Field

[0001] The present application relates to the technical field of sealing structures, and in particular to a sealing structure for a supersonic missile. Background Art

[0002] In various missiles with air-breathing power devices as the main power source and some large-sized missiles (i.e. missiles with a diameter of more than 500), there are various fairings (including cable covers) installed on the outside of the missile body, and a large number of equipment and cables are installed in these fairings (including cable covers). Therefore, in order to prevent the equipment in the cabin from being pulled by aerodynamic force or directly affected by aerodynamic heating, and to ensure the safe and stable operation of the equipment, the sealing of the cabin must be ensured.

[0003] Existing sealing solutions for supersonic missiles mainly include:

[0004] Solution 1: Add a flange on the metal fairing (including cable cover) where it overlaps with the shell, overlap the flange with the surface of the projectile, and use sealant to fill the gap to ensure the sealing of the cabin. However, since the material of the flange is usually consistent with the main material of the fairing (including cable cover), the thickness of the flange is consistent with the thickness of the fairing (including cable cover) (for example: the thickness is greater than 1.5mm), the hardness of the flange is relatively high. There are problems such as poor contact between the flange and the projectile, the need to repeatedly disassemble and assemble the fairing (including cable cover) during installation for flange shaping, and the shaping is difficult, grinding and / or cutting are often required, poor applicability, and poor interchangeability.

[0005] Option 2: Use non-metallic sealing strips in combination with sealants for sealing. Among them, non-metallic sealing strips are often high-silicon oxide. Due to the structural brittleness of high-silicon oxide, when the thickness of the non-metallic sealing strip is small (usually 3mm to 8mm), the length of the non-metallic sealing strip is severely limited, and the smaller the thickness of the non-metallic sealing strip, the shorter the length. For longer fairings (including cable covers), a larger number of non-metallic sealing strips are required to achieve the sealing effect. When the number of non-metallic sealing strips is large, there is a problem of cumbersome installation. During flight, due to the existence of aerodynamic heating, the missile body will have different length growth, the non-metallic sealing strip and the body have poor coordinated deformation, and the sealing effect will also be reduced. At the same time, conventional non-metallic materials have poor high temperature resistance. In high temperature environments, the materials will disintegrate and fail, and the price of high temperature resistant non-metallic materials is high. In the use of supersonic missiles, the economy is poor. Summary of the invention
