Problems solved by technology

[0005] At present, when protecting against microwave coupling by the back door, the method of adding a shielding layer is usually used, and the satellite itself is covered with a set of thermal control protection layers on the star surface, which is the first line of defense against the influence of strong electromagnetic waves, but This set of thermal control protection layers has the defect that it is damaged by strong electromagnetic waves
Therefore, we propose a star surface multi-layer heat insulation component with strong electromagnetic environment protection ability to solve the above-mentioned problem that the protective layer itself is easily damaged and burned by strong electromagnetic waves, which affects the normal operation of electronic equipment or devices inside the system

Embodiment 1

[0036] Please refer to figure 1 The shown structure schematic diagram of the first embodiment of a star surface multilayer heat insulation assembly provided by the application with strong electromagnetic environment protection capability, including:

[0037] layered components,

[0038] The anti-electromagnetic reinforcement mask group 3 is coated on the surface of the laminated assembly; the anti-electromagnetic reinforcement mask group 3 is connected to the laminated assembly by sutures 4;

[0039] The anti-electromagnetic reinforcement mask set 3 is provided with a polyimide layer 302 and a metal layer 303, and the metal layer 303 is arranged relatively close to the laminated assembly;

[0040] In use, the laminated assembly faces the product to be protected, and the polyimide layer 302 faces the external environment.

[0041] In this example, if figure 2 As shown, the laminated assembly has a reflective layer 1, the number of reflective layers 1 is at least five and st...

Embodiment 2

[0057] Such as Figure 4 As shown, when some cabin penetration cables need to penetrate the cabin, there are holes and gaps on the star, and high-power microwaves are easily coupled into the interior of the star through these holes, causing interference and even burning of sensitive devices inside the star. To block.

[0058] In order to prevent the problem of wave leakage in holes and gaps caused by cables, waveguides, pipelines, etc., the anti-electromagnetic reinforcement mask set 3 is designed as a structure that wraps the mask set 6 in holes and gaps;

[0059] Specifically, the hole gap wrapping mask group 6 is used to absorb the leakage wave caused by the cable lead, so that the power of the high-power microwave is greatly reduced when it reaches the hole through the cabin;

[0060] Hole and gap wrapping mask group 6 has the outer layer carburized polyimide layer 601, the middle metal layer 602 and the inner layer carburized polyimide layer 603 arranged in sequence, and...

Abstract

The invention discloses a satellite surface multi-layer heat insulation assembly with high electromagnetic environment protection capacity. The satellite surface multi-layer heat insulation assembly comprises a laminated assembly and an anti-electromagnetic reinforcing mask group covering the surface of the laminated assembly; the anti-electromagnetic reinforcing mask group is connected with the laminated assembly in a sewing manner through a sewing line; the surface of the laminated assembly is coated with the anti-electromagnetic reinforcing mask group, the laminated assembly and the anti-electromagnetic reinforcing mask group are sewn through the sewing line, the anti-electromagnetic reinforcing mask group is provided with the polyimide layer and the metal layer, the metal layer is relatively close to the laminated assembly, the laminated assembly faces a protected product during use, and the polyimide layer faces the external environment; the polyimide layer has good thermal control temperature characteristic and total dose effect, and the metal layer has the effects of electromagnetic radiation resistance and self damage resistance, so that the heat insulation assembly can be effectively prevented from being burnt down, and a protected product is prevented from being interfered by strong electromagnetic waves.

Description

technical field [0001] The present disclosure generally relates to the technical field of satellite strong electromagnetic environment protection, and specifically relates to a multi-layer heat-insulation component of a star surface with strong electromagnetic environment protection capability. Background technique [0002] Due to the increasingly important role of satellites in today's society, whether it is communication, navigation, or remote sensing satellites, the quality of communication and real-time working characteristics are increasingly demanding. In particular, navigation satellites have more prominent requirements for real-time communication, anti-interference, and precise positioning. The strong electromagnetic environment will seriously affect the positioning accuracy and communication of satellites. Therefore, satellites have higher and higher requirements for strong electromagnetic protection. [0003] The strong electromagnetic environment in space mainly i...
