Description
Technical field
Antenna house is the utility model is related to, more particularly to a kind of heat insulation structural of antenna house.
Background technology
With the raising of missile flight speed, Aerodynamic Heating problem is on the rise, and antenna house is located at the front end of guided missile,
It is the full position for playing Aerodynamic Heating most serious.At present, most of missile-borne radomes can only undergo a thermal shock process, stationary point temperature
About 800 DEG C of degree, heat time about 37.5s.With the increasingly lifting and the quickening of flying speed of guided missile function, some antenna houses
Experience one is also needed to reenter process, can be harsher in the situation of reentry stage Aerodynamic Heating, that is to say, that heat punching twice can be undergone
Hit process.Generally, the stagnation temperature of antenna house is up to 1200 DEG C when reentering, and continuous heating is for up to 310s.Lasting high temperature
Heating can raise the constant temperature of antenna house inwall and internal cavities, and the temperature at antenna may be up to 450 DEG C, be unsatisfactory for inside
The requirement of antenna, the failure of antenna function can be directly resulted in.
The agent structure of existing missile-borne radome is quartz-ceramics nose cone, as the transparent window of target seeker, is first had to full
Sufficient wave transparent requirement, bears aerodynamic loading, inertial load and thermal force, while plays certain heat-blocking action, makes the air of inner chamber
Temperature meets the requirement of antenna.Due to being restricted by requirement on electric performance, its wall thickness is often relatively thin, for time history
Short, for the antenna house for only undergoing a thermal shock, the effect of heat insulation of quartz-ceramics nose cone can meet to require, but for the time
Mileage is grown, and undergoes the antenna house of thermal shock twice, simple to be unsatisfactory for making for inside antenna by quartz-ceramics nose cone is heat-insulated
With requiring.
The content of the invention
The purpose of this utility model：One kind is provided on the premise of requirement on electric performance is met, the antenna house of good heat-insulation effect
Heat insulation structural.
The technical solution of the utility model：A kind of heat insulation structural of antenna house, it is characterized in that：Covered on antenna house inwall
There is thermal insulation tile.
Preferably, described thermal insulation tile is made up of aeroge or glass fiber compound material, and aeroge or glass fibre are answered
Condensation material has the characteristics of hot coefficient is small, specific heat capacity is big, in light weight and dielectric properties are excellent, can meet wave transparent requirement
Under the premise of effectively it is heat-insulated.
Preferably, described heat-insulated tilt sickness is 6-8mm, is the thickness after multidisciplinary optimization, can meet
Current design requirement.
Preferably, described thermal insulation tile is the absolute construction that outer mold surface can be engaged with antenna house inner mold face, with tradition
Spherical heat shield compare, its wave transparent performance and effect of heat insulation are more preferable.
Preferably, described thermal insulation tile is covered on antenna house inwall by way of gluing or gap coordinates, it is gluing or
The mode that gap coordinates is ripe technique, it is easy to accomplish.
The beneficial effects of the utility model：The technical program describes a kind of heat insulation structural of antenna house, in antenna house
It is internal stuffed heat insulated watt.Thermal insulation tile has the characteristics of thermal conductivity factor is small, specific heat capacity is big, in light weight and dielectric properties are excellent,
On the premise of meeting wave transparent requirement, the temperature of internal cavities can be reduced, meets the requirement of inside antenna.
Brief description of the drawings
Fig. 1 is a kind of heat insulation structural of antenna house；
Fig. 2 is the air themperature that antenna house inwall does not cover thermal insulation tile inner chamber；
Fig. 3 is the air themperature that antenna house inwall covers thermal insulation tile rear interior cavity.
Embodiment
The technical program is further described below with reference to Fig. 1：
A kind of heat insulation structural of antenna house, it is characterized in that：On antenna house inwall covered with thermal insulation tile, antenna house 1 and every
The thickness of heat watt 2 determines according to requirement on electric performance.Described thermal insulation tile is made up of aeroge or glass fiber compound material, described
Heat-insulated tilt sickness be 6-8mm, described thermal insulation tile is the absolute construction that outer mold surface can be engaged with antenna house inner mold face, system
The antenna house 1 and thermal insulation tile 2 for meeting to require are made, and the outer mold surface of thermal insulation tile 2 is processed into and the inner mold face symbol type of antenna house 1
Behind type face, assembled.Described thermal insulation tile is covered on antenna house inwall by way of gluing or gap coordinates.With
NASTRAN softwares carry out the emulation in temperature field, calculate the air themperature of inner chamber, assess its requirement for whether meeting antenna.
Fig. 2 is the air themperature that the inwall of antenna house 1 does not cover the inner chamber of thermal insulation tile 2, and Fig. 3 is that the inwall of antenna house 1 covers the rear interior cavity of thermal insulation tile 2
Air themperature, the air themperature of increase thermal insulation tile irdome day after tomorrow inner chamber reduces by 200 DEG C by 430 DEG C, while temperature rise rate drops therewith
Low, antenna can be with normal work.
