Abstract
The present invention relates to a kind of airborne antenna cover structure, more particularly to a kind of antenna cover structure that can be resistant to great-power electromagnetic ripple.Described antenna cover structure includes main wave transparent region and time wave transparent region, and secondary wave transparent region is general sandwich, and main wave transparent region is double glazing cloth composite.Provide a kind of antenna cover structure that can take into account antenna house intensity, rigidity and resistance to high-power requirement on electric performance.
Description
Technical field
The present invention relates to a kind of airborne antenna cover structure, more particularly to one kind can be resistant to high-power electricity
The antenna cover structure of magnetic wave.
Background technology
Airborne large-scale antenna dome generally uses glass both at home and abroad because of intensity and toughness and requirement on electric performance
Fibre reinforced plastics honeycomb sandwich construction, and it is different according to the honeycomb sandwich construction number of plies, it is divided into " A "
Sandwich antenna house, " C " sandwich antenna house, more sandwich antenna houses.
The resistance to power capability of general honeycomb sandwich construction antenna house can not meet Special Aircraft
The design requirement of high powered antenna emission system.Such as certain model aircraft " C " sandwich antenna
It is burned out when covering on task antenna emission test, bulge, carbonization, lamination occurs.Then
" A " the sandwich testpieces carried out is also burned out.The reason for through analyzing, burning is interlayer knot
Multiple interfaces and closing honeycomb chamber be present in structure.Electromagnetic wave when by more interlayers, multiple solutions it
Between pass through multiple reflections and absorption, electromagnetic wave energy loss increases, and is converted into heat energy.Heat energy
Closing honeycomb intracavitary can not heat loss through conduction, cause temperature to raise, when temperature exceedes antenna house material
After the heat resistance of material, there is bulge, carbonization, lamination, antenna house is burned out, function
Lose.
The content of the invention
The purpose of the present invention：Antenna house intensity, rigidity and resistance to high-power can be taken into account by providing one kind
The antenna cover structure of requirement on electric performance.
Technical scheme：A kind of airborne antenna cover structure, it is characterized in that：Described day
Irdome structure includes main wave transparent region and time wave transparent region, and secondary wave transparent region is general sandwich,
Main wave transparent region is double glazing cloth composite.
One kind as the technical program is improved, and described double glazing cloth is by a kind of glass fibre
The three dimensional fabric being made into, fabric thickness 6mm, superficial density is higher, and centre is mutually flat
Capable stud, stud spacing are 5-10mm.
One kind as the technical program is improved, and the stud of double glazing cloth is parallel to electromagnetic wave
Polarised direction.
One kind as the technical program is improved, and described double glazing cloth composite is hollow
Glass cloth and resin-based materials it is compound.
As the technical program one kind improve, by the double glazing cloth composite after shaping with
Sandwich solidification by cement shapes.
Beneficial effects of the present invention：Antenna house of the present invention and existing honeycomb sandwich construction antenna
Cover is compared, and on the basis of wave transparent performance is improved, can be carried the resistance to power-performance of airborne radome
It is high more than 3 times.Double glazing cloth composite is because mechanical property is low, electrical property and resistance to electromagnetism
Radiance is high, is independently used for airborne radome development, can not meet intensity and toughness requirement, leads to
Cross be inlaid into the high sandwich of intensity and toughness could airborne radome development on be applied.
Double glazing cloth composite inner only has longitudinal stud, and stud is by being parallel to each other and phase
Mutually independent fibre bundle is formed.Stud both sides space is mutually communicated, and has both reduced unlike material interface
Between multiple reflections absorb, be easy to heat conduct radiation, therefore electrical property and resistance to power again
It can greatly improve.Double glazing cloth composite is used for airborne radome and designs and make by the present invention
Make, improve airborne radome wave transparent performance and resistance to power-performance.

Embodiment
A kind of airborne antenna cover structure, it is characterized in that：Described antenna cover structure includes main wave transparent
Region and time wave transparent region, secondary wave transparent region are general sandwich, and main wave transparent region is hollow
Glass cloth composite.The three dimensional fabric that described double glazing cloth is made into by a kind of glass fibre,
Fabric thickness 6mm, superficial density is higher, the middle stud to be parallel to each other, between stud
Away from for 5-10mm.The stud of double glazing cloth is parallel to polarization of electromagnetic wave direction.Described
Double glazing cloth composite is the compound of double glazing cloth and resin-based materials.After shaping
Double glazing cloth composite shapes with sandwich solidification by cement.
First according to task Antenna Operation spatial domain and working frequency, airborne large-scale antenna dome is carried out
Subregion, it is divided into main wave transparent area and time wave transparent area, determines primary and secondary wave transparent area limit line 6.It is main saturating
Ripple region is that electromagnetic wave main lobe scans penetrating region and the region of a neighbouring wavelength；Secondary wave transparent
Area is that the wave transparent beyond main wave transparent area examines region.Because electromagnetic wave energy is concentrated mainly on main wave transparent
Area, main wave transparent area use high-performance transparent structure, and secondary wave transparent area uses honeycomb sandwich construction.It is main
Wave transparent area area is small, and the intensity and toughness of high-performance transparent structure can be guaranteed.
Secondly by double glazing cloth composite 3, including double glazing cloth composite faces 9,
Double glazing cloth composite stud 8 and double glazing cloth composite faces 7 are being molded successively
On mould then paving carries out forming and hardening；
Then the paving sandwich outer panels 4 on mould, in being inlayed in main wave transparent area
Empty glass cloth composite block, it is compound in double glazing cloth in secondary wave transparent area paving laminboard layer 2
Filling-foam glue between material block and laminboard layer 2, carry out structure precuring and repair.
Inlaying the main wave transparent area of double glazing cloth composite block and paving laminboard layer 2 again
Panel 5 in smooth paving sandwich in secondary wave transparent area, in paving laminboard layer 2, then enter thereon
The precuring of row structure and finishing.
Last paving sandwich wainscot 1 simultaneously carries out final curing molding.
