Shown in reference picture 4, a kind of preparation side of grapefruit satellite Stealthy reflector Antenna cover based on frequency-selective surfaces of the invention
Method, including step are as follows：
1) mould prepares；
2) internal layer FSS screens prepare, and internal layer FSS screens are navigated to the surface of metal positive；
3) in internal layer FSS screens outer surface paving inside panel, inside panel shaping；
4) glued membrane, intermediate layer prepare, and inside panel outer surface and intermediate layer are glued；
5) force-supporting belt is molded；
6) glued membrane, intermediate layer prepare, and intermediate layer and exterior skin are glued, exterior skin shaping；
7) in exterior skin outer surface paving outer layer FSS screens；Outer layer FSS screens are glued in positioning；
8) prepared by outer layer FSS screens and exterior skin venthole；
9) antenna house tip repairing type.
The key technology of above-mentioned preparation technology：
Honeycomb splices with combining：
Above-mentioned steps 4) in, because the application of the preparation method is to make an antenna house, antenna house profile is six ribs point
Tapered, antenna is covered with six seamed edges, at seamed edge honeycomb can not symbol type completely, and honeycomb deformation is larger, and honeycomb is pressurized easy
Unstability be collapsed.Therefore, using the method for honeycomb burst, honeycomb is processed into six by the size of faceted pebble, in rib after honeycomb combination
It is filled in the honeycomb checkerwork cell on line both sides using inserts, to avoid honeycomb compression be collapsed.
Outer FSS screens and exterior skin are integrally punched：
Above-mentioned steps 8) in, antenna house is beaten the outer layer FSS screens and exterior skin being molded as one after the complete outer FSS screens of paving
Hole, should try one's best during punching and reduce the destruction for subelement of being gone into battle to FSS screens.After the punching of antenna house extexine, antenna house is realized
Vacuum deflation structure function.
Tip and seamed edge shaping：
Above-mentioned steps 9) in, because antenna house pointed cone angle is smaller, and honeycomb deformation is larger, the easy unstability of honeycomb compression.
It is filled in the honeycomb of antenna house tip with inserts.Because tip and seamed edge have R2 fillet, by the inserts on honeycomb surface
After polishing flat, then tip and seamed edge are gently polished to R2 fillet.Inserts, which is reused, after exterior skin shaping repairs point
Portion and seamed edge, then paving FSS screens.
In order to test the Stealthy reflector Antenna cover applied to after satellite, the change of the Stealth Fighter of satellite has carried out satellite different
RCS test under state, i.e. Stealth Fighter is tested.Fig. 8 and Fig. 9 are respectively illustrated：When satellite antenna is in 30 ° of horizontal strokes
Under roll angle, the satellite RCS under FSS antenna house two states is whether there is.It can be seen that by Fig. 8 and Fig. 9：By to without Stealthy reflector Antenna cover,
The satellite RCS for having Stealthy reflector Antenna cover is contrasted, in the case of two kinds, and nose cone is in the range of ± 40 °, when satellite is not added with Stealthy reflector Antenna cover
RCS values are not less than 2.3m2, the no more than 0.12m of the satellite RCS values with Stealthy reflector Antenna cover2.Show the stealthy day of frequency-selective surfaces
After irdome is added on satellite, satellite has preferable stealth effect.
Concrete application approach of the present invention is a lot, and described above is only the preferred embodiment of the present invention, it is noted that for
For those skilled in the art, under the premise without departing from the principles of the invention, some improvement can also be made, this
A little improve also should be regarded as protection scope of the present invention.
