In-situ utilization based space fragment treatment method

Abstract

The invention relates to an in-situ utilization based space fragment treatment method and belongs to the technical field of aerospace. The in-situ utilization based space fragment treatment method comprises following steps of step 1, conveying space fragments under a microgravity condition: utilizing a space fragment storage vessel with a telescopic bottom and a double-roller feeding device to feed the space fragments into a feeding hole of a crushing and grinding device; step 2, crushing and grinding the space fragments which are made of various materials and in various sizes: performing two-stage physical crushing and grinding on the multi-size irregular space fragments made of various materials by utilizing a shearing type double-roller crusher and a crushing and grinding machine; and step 3, sieving mixed solid powder under the microgravity condition: utilizing modes of magnetic separation, eddy current, static electricity and the like to perform multi-stage sieving on space fragment powder. By adopting the in-situ utilization based space fragment treatment method, the space fragments can be powdered under spatial microgravity, the solid powder with different characteristics isaccurately sorted, a space fragment treatment target is changed from removal to reutilization, and resource reutilization of the space fragments is realized.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a method for processing space debris based on in-situ utilization. Background technique [0002] With the development of aerospace technology, more and more spacecraft are launched into Earth orbit as a by-product of space activities—ejections and jettisons produced by a large number of vehicles, invalid spacecraft, explosions of space objects, impacts Debris and the like are stranded in Earth orbit, forming a large amount of space debris. [0003] At present, the world's space powers still regard space debris as garbage, and their main focus is on the orbital removal of space debris in terms of processing methods. The used space location was moved to a location temporarily unavailable to human beings, and the space debris was not completely cleared. If this "traditional" space waste is transformed into non-traditional space resources in a high-tech and high-efficiency way, ...
