A method for deployable mechanism to protect high-energy electrons

Abstract

The invention discloses a high-energy electron defending method of a foldable mechanism. The method is achieved through an inflating unfolding film, an inflating device, a solid powder releasing device, a temperature maintaining device and a sensor system; by combining the inflating unfolding film and spread solid powder, space high-energy electrons can be effectively defended.

Description

technical field [0001] The invention belongs to the field of space protection, and is suitable for the protection of high-energy electrons of various spacecraft, especially the protection of high-energy particles of deep space probes, and in particular relates to a method for protecting high-energy electrons with an expandable mechanism. Background technique [0002] There are a large number of high-energy particles (electrons, protons, etc.) in the space where the spacecraft is located, and they are one of the main causes of satellite failures and abnormalities. When the high-energy particles accumulate on the surface of the spacecraft, it will cause surface charging; when the high-energy particles pass through the surface of the satellite, they will be transported and deposited inside the electrolyte material of the satellite components, which will cause the internal medium to be charged. If the electric field generated by charging exceeds a certain breakdown threshold, di...

Problems solved by technology

[0003] At present, the protection of high-energy charged particles at home and abroad includes active protection and passive protection. Active protection methods include electric field protection, magnetic field protection, etc. Electric field protection has unsolvable problems such as high power consumption. Magnetic field protection designed using superconducting wires There are problems such as difficulty in magnetic field configuration design, low magnetic field strength and inability to shield particles with high energy (especially protons). At the same time, the opening and closing and weight of the magnetic sheath bracket need to be demonstrated in detail; passive protection, that is, improving the protection of the components themselves The ability to resist radiation and cover the surface of the components with a radiation-resistant cover, but the thickness of the radiation-resistant cover needs to increase with the increase of the energy of the charged particles, which will greatly increase the quality of the spacecraft. At the same time, because the radiation particles can and protect Layer interaction, produce secondary charged particles, such as gamma jets, protons, etc., but increase the overall radiation dose, making the environment of charged particles inside the spacecraft even worse
