Embedded dustproof and dampproof structure of missile engine

Abstract

The invention discloses an embedded dustproof and dampproof structure of a missile engine. The embedded dustproof and dampproof structure of the missile engine comprises a missile engine tail body and the embedded dustproof and dampproof structure. The embedded dustproof and dampproof structure can guarantee that foreign bodies like dust do not enter an engine inner cavity from an engine tail part during the transportation and storage process of the missile engine, non-metallic components and a cohesive glue layer in the engine are prevented from being in direct contact with factors like moisture or mould of the external environment, ageing of the non-metallic components of the engine tail part is reduced, and the storage life of the missile engine is prolonged; and the structure of the embedded dustproof and dampproof structure is not liable to damage or age during the transportation and long-term storage process, and the structure is effectively dustproof and dampproof during the whole life cycle of a missile.

Description

technical field [0001] The invention relates to the field of solid rocket propelling, in particular to a missile motor embedded dust-proof and moisture-proof structure. Background technique [0002] The dust-proof and moisture-proof structure is a necessary structure during the transportation and storage of solid rocket motors. The dust-proof and moisture-proof structure can ensure that foreign matter such as dust in the external environment will not enter the engine cavity, and at the same time avoid moisture, mold, etc. in the external environment Factors are in contact with the non-metallic parts inside the engine and the adhesive layer, slowing down the aging of engine parts and helping to prolong the storage life of missile engines. [0003] The dust-proof and moisture-proof structure of the existing missile engine is mainly adopted in the way of bonding a frustum-shaped foam plugging cover on the inner surface of the diffuser section of the tail nozzle. The main probl...

AI Technical Summary

Problems solved by technology

The main problems of the bonded dust-proof and moisture-proof structure are: the bonding adhesive layer between the foam plug and the inner surface of the diffusion section is easily damaged during the transportation of the engine, causing the foam plug to fall off; at the same time, the long-term storage of the engine will also cause This will lead to the aging of the adhesive layer between the foam plug and the diffusion section, which will cause the foam plug to fall off
