Problems solved by technology

Fragile front covers are mostly made of polyurethane or epoxy foam materials. Long-term storage is easy to be brittle. After launching and breaking the cover, a large number of fragments will be generated, which will cause harm to ground personnel and equipment, and pose a safety hazard.

Embodiment Construction

[0019] like figure 1 As shown, it is a composite material easy-to-crack front cover that can be opened on one side. In the figure, the front cover includes screws 1, pressure plate 2, cover body 3, cover frame 4, sealing ring 5, direction of cover breaking 6, cover body thickening layer 7 , steel wire 8, anti-falling off fixing screw 9. Put the sealing ring 5 into the cover frame 4, put the cover body 3 into the cover frame 4 coated with polysulfide sealant, press the cover body firmly with the pressure plate 2 and screw the cover body 3 and the cover frame 4 through the screw 1 , Pressing plate 2 is locked.

[0020] like figure 2 As shown, it is a partial reinforcement structure diagram of the front cover, and the steel wire 8 is connected to the cover 3 through the anti-falling fixing screws 9 and connected to the cover thickening layer 7 .

[0021] like figure 1 , figure 2 As shown, the cover frame 4 and the pressing plate 2 are made of structural steel. The sealing...

Abstract

The invention relates to a missile launcher technology. In order to solve the problems of easy embrittlement during long-term storage of an easily-cracking front cover and potential safety hazards due to a large quantity of fragments after the cover is broken after launched, the invention provides a composite easily-cracking front cover opened in one side and a making method of the composite easily-cracking front cover. Compared with the prior art, the composite easily-cracking front cover has the advantages and the beneficial effects of light weight, high strength and good compaction due to the adoption of a composite, and can ensure that the front cover structure is more reasonable in performance and is greatly improved in sealing property; and made by adopting a mold, the composite easily-cracking front cover has the advantages of capability of effectively controlling precision and ensuring that cover breaking pressures are consistent, rapidness, high efficiency and stable quality; and an opened cover body can not be separated from the launcher so as to eliminate potential safety hazard caused by scattering broken fragments after the cover is opened. The composite easily-cracking front cover is formed through medium-temperature curing, can be reliably used under the condition of high-temperature and low-temperature environments, and is difficult in embrittling and cracking.

Description

technical field [0001] The invention relates to missile launching tube technology, in particular to the front cover of the missile launching box made of composite materials, which can make the easily cracked front cover single-test open without falling off. Background technique [0002] As an important component of the launch tube (box), the front cover has a direct impact on the missile's storage life, maintainability and launch reliability. With the rapid development of missile launch technology, the front cover of the launch tube (box) is required to have a certain strength and rigidity, and it must also have good air tightness, electromagnetic shielding, and ablation resistance. The cover is convenient and reliable, and does not affect the normal launch of the missile. In recent years, the use of non-metallic materials instead of metal materials, and the use of fragile or breakable covers instead of mechanical opening have become a new development direction of missile l...
