Abstract

The invention relates to the technical field of space debris utilization, in particular to a space debris energy transformation device and method based on laser propelling. The device comprises a device body, an optical aligning mechanism, an optical beam splitting mechanism, optical working medium coupling mechanism and working medium supplying mechanisms, wherein the optical beam splitting mechanism is arranged on the bottom of the optical aligning mechanism, and the optical working medium coupling mechanisms are correspondingly connected with the working medium supplying mechanisms in a one-to-one manner. According to the space debris energy transformation device and method based on laser propelling, space debris serves as a solid working medium for laser propelling, by means of interaction of laser and the collected space debris, space debris ablation and gasification are caused, the space debris is ionized to form plasmas, plasma deflagration waves compress the surface of the space debris to produce thrust, so that reuse of the space debris is achieved. The space debris energy transformation device has the beneficial effects that the structure is simple, the energy transformation utilization rate is high, and secondary pollution cannot be caused for the space environment. The space debris energy transformation and method based on laser propelling can be directly applied to in-orbit control over spacecrafts.

Description

technical field [0001] The invention relates to the technical field of space debris utilization. Background technique [0002] As a harmful existence, space debris has restricted and harmed space activities for a long time, and the increasing number of space debris has seriously affected space security. The traditional way of space maintenance is to remove space debris from orbit, which can protect the operating environment of space vehicles, but it also causes direct waste of these space debris materials. Therefore, to explore a way to effectively use space debris to serve space vehicles The new approach has great application value. Contents of the invention [0003] (1) Technical problems to be solved [0004] The purpose of the present invention is to provide a space debris energy conversion device and method based on laser propulsion to solve the problem that space debris materials in traditional space maintenance methods cannot be effectively utilized. [0005] (2)...
