Abstract
It the utility model is related to a kind of refractory ceramics structure radome of built-in metal ring, more particularly to antenna house built-in metal ring (2) root attachment structure.Becket (2) is sleeved in antenna house, positioned at root position, is evenly equipped with screwed hole on becket and antenna house link position periphery, the corresponding position of antenna house is provided with hole；Becket is fixedly connected with antenna house by bolt (6), screwed hole insertion antenna house cover body on antenna house, the stud length of the bolt is less than becket and antenna house thickness sum, and the space between stud termination and antenna house cover body outer surface is filled with fluid sealant (4).The utility model solves ceramic structure radome and the thermally matched problem of becket under hot environment.
Description
Technical field
A kind of refractory ceramics structure radome of built-in metal ring is the utility model is related to, more particularly to built in antenna house
Becket root attachment structure.
Background technology
With current, high temperature guided missile cover all passes through splicing using the cover body of high temperature ceramic material composition with metal connection ring
Connection is formed, the structure of this form, in guided missile cover structure of the guided missile capouch portion no more than 500 DEG C, can be undertaken bonding and be carried
Lotus, but reach for head in 1200 DEG C of guided missile cover, root bonding pad hull-skin temperature can reach 900 DEG C, inner surface
Temperature internal surface temperature can reach 400 DEG C.The transmission force property of glue sticking disappears, and causes ceramic nose cone deformation excessive, causes pottery
The local compression that porcelain head is bored between connection ring destroys.
The content of the invention
The purpose of this utility model：A kind of reliability height that is connected is provided, is easy to gold built in the antenna house of Project Realization
Belong to ring root attachment structure.
The technical solution of the utility model：A kind of antenna house built-in metal ring root attachment structure, it is characterized in that：Becket
It is sleeved in antenna house, positioned at root position, screwed hole is evenly equipped with becket and antenna house link position periphery, in day
The corresponding position of irdome is provided with hole；Becket and antenna house are bolted to connection, the screwed hole insertion on antenna house
Antenna house cover body, the stud length of the bolt are less than becket and antenna house thickness sum, stud termination and antenna house cover body
Space between outer surface is filled with fluid sealant.
Preferably, 1 ㎜ gaps are stayed among becket and cover body, fluid sealant is applied among gap.
Preferably, described antenna house is high temperature ceramic material.
The beneficial effects of the utility model：The rigidity of link can be increased, reduce the connection stress in ceramic nose cone so that
Stress in nose cone is reduced to alap level；Sealant is no longer undertaken binding function, only undertake sealing function.Drop
The difficulty of low antenna house development, in the past, substantial amounts of quiet heat integration experiment is needed in the development of antenna house, glue-line is adjusted by testing
Thickness, connection width and correlation the thickness at local ceramic joining position and the thickness of connection ring.And built-in metal ring root
Portion connecting structure has bigger design tolerance, for given structure, has very big design margin.
Brief description of the drawings
Fig. 1 is antenna house root attachment structure schematic diagram.
Embodiment
Solves the operation principle of thermally matched problem：Connected between radome 1 and becket 2 by 16 bolt threads, gold
1 ㎜ gaps are stayed among category ring and cover body, under normal temperature environment, part fluid sealant (3,4,5) makees sealant and sealing is played to cover body
Effect, as temperature raises, sealant melts, and radome 1 expands, and the radome 1 after expansion can take fluid sealant (3,5)
Space after thawing.Be not in damage phenomenon caused by being extruded due to expansion while reaching sealing effectiveness.Simultaneously as
It is spirally connected between radome 1 and becket 2 by bolt 6, the head of bolt 6 is located at and inside antenna house, the stud length of bolt is small
In becket and antenna house thickness sum, i.e. bolt 6 passes through radome 1 without penetrating, stud termination and antenna house cover body appearance
Space between face is filled with fluid sealant 4, and fluid sealant 4 melts remains space for the expansion of bolt 6, is so not in due to heat
The coefficient of expansion is different and appearance deformation is inconsistent, and the phenomenon for ultimately resulting in structure destruction occurs.
