Abstract
The invention relates to the technical field of radome electrical properties and structures, and discloses a radome electrical property optimizing linkage unit part. The radome electrical property optimizing linkage unit part comprises a main part and a connector part, and further comprises a glass fiber reinforced plastic layer on the upper surface, a glass fiber reinforced plastic layer on the lower surface and a foam material filling the part between the upper surface and the lower surface. The connector part is located on the side edge of the main part, the thickness of the connector part is smaller than that of the main part, a reinforcing layer is arranged inside the connector part and is located inside the foam material, and a screw hole is formed in the connector part and penetrates through the glass fiber reinforced plastic layer on the upper surface, the glass fiber reinforced plastic layer on the lower surface and the reinforcing layer. The demands of high frequency and a wideband antenna are met through the hollow foam structure of the connector part, and the structural strength of a radome is enhanced through the reinforcing layer.

Technical field
The present invention relates to radome electrically and technical field of structures, particularly a kind of radome is electrically optimized the linkage unit part.
Background technology
Referring to accompanying drawing 1, radome is assembled by some unit pieces 1, between unit piece 1 and unit piece 1, by fastening bolt, is formed by fixedly connecting.
Referring to accompanying drawing 2, the connector portions of existing unit piece 1 is to offer screw on solid fiberglass body.And the design of joint also requires the minimum that stops to electric wave except considering extraneous load (being mainly wind carries).Existing joint type of attachment can not meet the electrical requirement of existing radome.
Summary of the invention
To the objective of the invention is in order solving the problems of the technologies described above, to provide a kind of radome electrically to optimize the linkage unit part, its joint is taken into account structure and the electrical property feature of radome, improves the performance of radome.
The technical scheme that the present invention takes is:
A kind of radome is electrically optimized the linkage unit part, comprise main part and connector portions, it is characterized in that, described linkage unit part comprises the frp layer on upper and lower two surfaces and the foamed material that two interior surface are filled, described joint area is in the main part side, the thickness of described connector portions is less than the thickness of described main part, in described connector portions, reinforced layer is set, described reinforced layer is positioned in the middle of described foamed material, have screw on described connector portions, described screw is through frp layer and the described reinforced layer of described upper and lower surface.
Further, described reinforced layer is 2 to 3 layers, is close to respectively on the frp layer of described upper and lower surface.
Further, be provided with nut in described screw.
The invention has the beneficial effects as follows:
(1) the hollow foam structure of connector portions, met the requirement of high frequency and wide frequency antenna;
(2) reinforced layer increases the structural strength of radome.
The accompanying drawing explanation
Accompanying drawing 2 is the structural representation of existing linkage unit part;
Accompanying drawing 3 is the structural representation that radome of the present invention is electrically optimized the linkage unit part.
Mark in accompanying drawing is respectively:
1. linkage unit part; 2. main part;
3. connector portions; 4. frp layer;
5. foamed material; 6. reinforced layer;

Referring to accompanying drawing 3, radome is electrically optimized linkage unit part 1 and is comprised main part 2 and connector portions 3, linkage unit part 1 comprises the frp layer 4 on upper and lower two surfaces and the foamed material 5 that two interior surface are filled, connector portions 3 is positioned at main part 2 sides, the thickness of main part 2 is greater than the thickness of connector portions 3, at the interior reinforced layer 6 that arranges of connector portions 3, reinforced layer 6 is positioned at foamed material 5, reinforced layer 6 is generally 2 to 3 layers, a part that penetrates the reinforced layer 6 of main part 2 is positioned at the centre of foamed material 5, reinforced layer 6 in connector portions 3 is close to respectively on the frp layer 4 of upper and lower surface.Take scheme in 3 layers of reinforced layer be example, second layer reinforced layer is positioned at the centre of foamed material 5 in main part 2, is attached to upper surface frp layer 4 upper of connector portions 3 together with the ground floor reinforced layer, the 3rd layer of reinforced layer is attached to the upper of lower surface frp layer 4.Have screw 7 on connector portions 3, screw 7 is through frp layer 4 and the reinforced layer 6 of upper and lower surface.Be provided with nut 8 in screw 7.
Below the present invention while being used on 25 meters radomes, its construction stretch result of the test, as following table:
| |
1 | 2 | 3 | 4 | 5 | Average |
| Ultimate elongation power (KN) | 26.9 | 29.5 | 19.1 | 24.2 | 20.3 | 24 |
And the tag data of joint design mode of the prior art is as following table:
| |
1 | 2 | 3 | 4 | 5 | Average |
| Ultimate elongation power (KN) | 16.5 | 14.1 | 17.2 | 14.1 | 15.0 | 15.4 |
This shows, the present invention, improving the stretching structure aspect of performance, has good effect.
The test of electrical property seam and the seam test data of general joint that adopt this joint to carry out are compared as follows table:
The electrical property seam test that adopts this joint to carry out:
| Frequency GHz | 1.0 | 1.1 | 1.4 | 1.6 | Average |
| Wave transparent rate % | 95.9 | 97.9 | 98.4 | 97.9 | 97.5 |
The seam test data of prior art center tap:
| Frequency GHz | 1.0 | 1.1 | 1.4 | 1.6 | Average |
| Wave transparent rate % | 95.5 | 97.6 | 98.5 | 96.4 | 97.0 |
From two groups of Data Comparison situations, adopt this joint little for the impact of L-band scope internal loss, suitable with joint wave transparent situation of the prior art.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
