A Low-Cost Space Debris Removal Method Using Ground-Based Electromagnetic Launchers

Abstract

The present invention provides a space debris low-cost removal method by using a ground-based electromagnetic launcher. The space debris low-cost removal method by using the ground-based electromagnetic launcher is characterized by concretely comprising the following steps: 1 launching a vehicle with particle clusters by adopting the electromagnetic launcher, and the vehicle forming a high-toss trajectory with the launching speed being less than the first cosmic speed, and the vertex of the high-toss trajectory of the vehicle being located at the area near a space debris orbit to be removed; 2, when the vehicle gets close to the vertex of the high-toss trajectory of the vehicle, the vehicle adjusting the posture, and when the vehicle is located at the vertex of the high-toss trajectory of the vehicle, the vehicle ejecting the particle clusters carried, to make the particle clusters to be spread evenly on the space debris orbit to be removed to form a particle cloud cluster; 3, the space debris to be removed colliding with the particle cloud cluster on the orbit to lose kinetic energy, and lowering the orbit step by step till falling into the atmosphere to be destroyed. The method adopts the ground-based electromagnetic launching, and has the advantages of low cost, high reliability and capability of being reusable, so that the debris removal cost can be greatly reduced.

Description

technical field [0001] The invention mainly relates to the field of aerospace control technology, in particular to a low-cost method for removing space debris using a ground-based electromagnetic launcher, which is suitable for solving the problem of cost reduction in the field of space debris removal. Background technique [0002] The increasing amount of space debris near the earth poses a serious challenge to the prosperity and development of human space. Among them, there are more than 500,000 debris that threaten the flight safety of spacecraft. The removal of these debris has become the consensus of the international community. However, the high cost of removal prevents countries from carrying out large-scale space debris removal activities. It can be seen that in order to completely solve the problem of space debris, the cost of removing space debris must be greatly reduced. [0003] Traditional space debris removal methods, including projecting flying nets and spray...
