Abstract
The invention belongs to antenna house fields, and in particular to arrive a kind of assorted fibre antenna house.Antenna house is the c-type sandwich being made of inside panel, foamed core, middle covering, foamed core and exterior skin, wherein inside panel and exterior skin include Kevlar fibrous layer and glass layer, two kinds of fibers carry out laying in such a way that interlayer mixes, middle covering is simple glass layer, inside, middle covering and in, isotropic, low density foamed core are used among exterior skin.Solve the problems, such as the intensity after SAR Communications equipment high-altitude is cast and Electro-magnetic Wave Penetrate, a kind of pendant that assorted fibre antenna house can not only withstand up to 3500J hits shock loading, absorb impact energy, play the role of vibration isolation and vibration damping, and there is good Electro-magnetic Wave Penetrate performance, meet the positioning function of antenna；In addition, a kind of main body of assorted fibre antenna house is composite material, lighter in weight being capable of effective loss of weight.
Description
Technical field
The invention belongs to antenna house fields, and in particular to arrive a kind of assorted fibre antenna house.
Background technique
After aircraft distress accident, professional can carry out crash analysis by airmanship parameter and the communication information, with
Upper information is usually recorded by specific aviation SAR Communications equipment.In order to which, convenient for finding, SAR Communications equipment has after accident
Antenna is positioned, investigator is scanned for specific receiver, and discovery signal can determine position.SAR Communications equipment from fly
After being cast on machine, if falling in land, greatly pendant can be generated and hit shock loading, therefore, corresponding protection need to be taken
Measure.It is at present usually to wrap up metal protection layer in the external of SAR Communications equipment, but metal protection layer not only seriously affects day
The positioning function of line increases search difficulty, and metal rigidity is big, and the little energy of absorption, effectiveness in vibration suppression is poor, in addition, metal
Density is big, heavier-weight, is usually unsatisfactory for the weight demands of design.
Summary of the invention
The present invention in view of the above-mentioned problems, SAR Communications equipment a kind of assorted fibre antenna house of exterior design, the antenna
Cover on receiving pendant hit shock loading (impact energy is up to 3500J) structure it is non-destructive under the premise of, certain energy can be absorbed, protect
Shield positioned internal antenna and SAR Communications equipment are not damaged, while having good Electro-magnetic Wave Penetrate performance, meet the positioning of antenna
Function reduces search difficulty；In addition, a kind of main structure body of assorted fibre antenna house is composite material, light-weight, weight loss effect
Significantly.
The invention proposes a kind of assorted fibre antenna house, be able to solve SAR Communications device external shield intensity and
The contradictory problem of electrical property.A kind of assorted fibre antenna house uses c-type foamed sandwich structure form, and c-type sandwich can be seen
At being combined by two A type sandwiches, c-type sandwich can offset the extra back wave of independent A sandwich,
Improve the wave transparent performance of big incidence angle and increase electromagnetic wave frequency bandwidth, can satisfy the positioning function of antenna, greatly drop
Low search difficulty；Kevlar fiber is used in a kind of assorted fibre antenna house in exterior skin, Kevlar fiber has high ratio
The excellent characteristics of intensity and high ratio modulus, the pendant that can resist high-energy hit shock loading and effective energy-absorbing；In addition, C-type clamp layer
Structure has more excellent mechanical property and waterproof performance compared to the identical A type sandwich of overall thickness, and density is relatively golden
Belong to much smaller, it being capable of effective loss of weight.
Technical solution
A kind of assorted fibre antenna house, antenna house are by inside panel, foamed core, middle covering, foamed core and exterior skin
The c-type sandwich of composition, wherein inside panel and exterior skin include Kevlar fibrous layer and glass layer, and two kinds of fibers use
The mode that interlayer mixes carries out laying, and middle covering is simple glass layer, inside, middle covering and in, adopt among exterior skin
With isotropic, low density foamed core.
The thickness of three layers of covering and two layers of sandwich layer is determined through electricity matching.
Skin material is high-intensitive wave-penetrating composite material.
Foamed core uses the low density material of excellent dielectric performance and cutting performance.
The c-type sandwich need to meet wave transparent performance, and have shock resistance and absorb the ability of energy.
Technical effect
The present invention can solve intensity and Electro-magnetic Wave Penetrate problem after SAR Communications equipment high-altitude is cast, a kind of assorted fibre
The pendant that antenna house can not only withstand up to 3500J hits shock loading, absorbs impact energy, plays the role of vibration isolation and vibration damping,
And there is good Electro-magnetic Wave Penetrate performance, meet the positioning function of antenna；In addition, a kind of main body of assorted fibre antenna house is
Composite material, lighter in weight being capable of effective loss of weight.
Detailed description of the invention
Fig. 1 is wall structure of radome schematic diagram.
Specific embodiment
Technical solution of the present invention is further described below with reference to attached drawing:
Referring to Fig. 1, the inside panel of contoured beam antenna cover first, inside panel by Kevlar fibrous layer and glass layer according to
Form that interlayer mixes carries out laying, after the completion of laying in autoclave curing molding；
Referring to Fig. 1, placing the foamed core processed on the glass layer of inside panel, it is solidified into autoclave
Type；
Referring to Fig. 1, the covering in the outer surface of foamed core is laid with, middle covering is simple glass layer, laying
The curing molding in autoclave after the completion；
Referring to Fig. 1, the foamed core processed is placed on middle covering, the curing molding in autoclave；
Referring to Fig. 1, being laid with exterior skin in the outer surface of foamed core, exterior skin is by glass layer and Kevlar fiber
The form that layer mixes according to interlayer carries out laying, after the completion of laying in autoclave curing molding.
