A method and device for removing space debris

Abstract

The invention discloses a method and a device for removing space debris. The method is to apply electromagnetic force to the space debris running in the original orbit; the size and / or direction of the speed of the space debris change under the action of the electromagnetic force; ; The perigee height of the space debris at least in the new orbit is lower than the perigee height of the space debris in the original orbit; the space debris in the new orbit will eventually fall into the earth's atmosphere under the action of atmospheric drag. The device includes a satellite carrying platform; the satellite carrying platform is provided with an electric field device or a magnetic field device or a combination of the electric field device and the magnetic field device for removing space debris. The present invention does not require high precision for space debris position detection, can effectively remove tiny space debris, can fully utilize solar energy to generate electricity, saves energy, and has the beneficial effects of simple structure, low manufacturing cost and better pulse effect.

Description

technical field [0001] The invention belongs to the field of aerospace technology, in particular to a method and a device for removing space debris. Background technique [0002] Space debris refers specifically to the waste and its derivatives produced by human beings in space activities. Space debris comes from a variety of sources. No one can count the exact number of space debris. At present, humans can only track and monitor fragments with a diameter of more than 10 centimeters. As of April 2013, there are more than 16,649 such fragments. Among them, the United States and Russia, which have carried out space activities for a long time, accounted for about 29.7% and 37.6% of the total space debris, and my country accounted for about 22.5%. It is estimated that there are tens of millions or even hundreds of millions of debris smaller than 1 centimeter. The spacecraft cannot avoid colliding with it, and can only deal with it by strengthening its own protection capabilit...

AI Technical Summary

Problems solved by technology

Use the force of pulsed laser to change the orbit of space debris; the technology of pulsed laser to remove debris requires point-to-point thrust, which means that the accuracy of debris position detection and aiming launch is very high. Therefore, for tiny space debris ( less than 1 cm) can hardly be removed effectively
