Embodiment Construction

[0024] The invention provides a truss type radome, adopting basalt fiber as the main material of the radome, which has the advantages of high temperature resistance, chemical stability, corrosion resistance, etc., and its thermal conductivity, insulation, friction resistance and electrical properties, etc. Index is better than glass fiber.

[0025] see Figure 1 to Figure 3 The truss type radome of the present invention adopts a hollow truncated spherical skeleton, on which several triangular rib units 201 are spliced ​​into the radome, and each triangular rib unit is composed of three ribs 203 and the radome skin, so The triangular rib unit 201 is made of basalt fiber, and the radome skin is connected with the triangular rib unit 201 and arranged on the surface of the triangular rib unit 201 .

[0026] Wherein, the cross-section of the rib 203 is rectangular, with holes on the surface for installing bolts; two adjacent ribs 203 are fixed by nodes 204, and several bolt holes ...

Abstract

The invention discloses a truss type radome which adopts a hollow truncated spherical skeleton. A plurality of triangular rib units are arranged on the skeleton to be spliced into the truss type radome, and each of the triangular rib units comprises three ribs and a radome skin which is arranged on the surface of the triangular rib unit. The triangular rib unit and the radome skin are made of basalt fiber. The truss type radome adopts the hollow truncated spherical skeleton and splices the plurality of triangular rib units on the skeleton to form the radome. Each of the triangular rib units comprises the three ribs and the radome skin which is arranged on the surface of the triangular rib unit. In order to facilitate the factory production and installation, the triangular units are used to easily remove the radome, so that transport, use and maintenance are convenient. The top of each fiber rib has a certain flange facilitating assembly and bonding later. The triangular rib units and the radome skins are made of the basalt fiber material, which can effectively avoid the interference of metal materials on a radar antenna.

Description

technical field [0001] The invention belongs to the technical field of radar antennas, in particular to a truss type radome. Background technique [0002] A radome is a wave-transparent shell that protects the antenna from the natural environment. It is a covering made of natural or artificial dielectric materials, or a specially shaped electromagnetic window composed of a dielectric shell supported by a truss. A well-designed radome, in addition to the functions of protection, conductivity, reliability, concealment and decoration, can also prolong the service life of each part of the entire system, reduce life costs and operating costs, simplify design, and reduce maintenance costs , Ensure the accuracy of the antenna surface and position, and create a good working environment for antenna operators. However, the radome will also affect the electromagnetic radiation of the ideal antenna, reducing the electrical performance of the ideal antenna. Radome design is a complex d...
