Atmospheric drag passive aberrance device and method applied to medium-low orbital rocket tail stage

Abstract

The invention discloses an atmospheric drag passive aberrance device and a method applied to a medium-low orbital rocket tail stage and belongs to the field of prevention and management of space junk. The device comprises a control system, an inflation system, an ejection system and an inflation body, wherein the inflation body is folded in the ejection system, and is connected with the inflationsystem; the control system is connected with a power supply on a rocket, the ejection system and the inflation body; and the control system controls the ejection system, thus the inflation body is inflated by the ejection system. In the invention, the inflation body is rigidized through inflating the inflation body by using the inflation system, a large effective area is provided for the rocket tail stage, great atmospheric drag is generated, and the passive aberrance of the atmospheric drag at the rocket tail stage is realized, thus the service life of the rocket tail stage is shortened. According to the invention, the residual energy sources of the rocket tail stage can be fully utilized, thus the generation of space junk is reduced substantially, and the orbital service life of the rocket tail stage is shortened; and the inflation body in the invention is made of an Al-Mylar-Al laminating thin film material, thus the inflation body has light weight, and is easy to rigidize and fold.

Description

technical field [0001] The invention belongs to the field of prevention and treatment of space debris, and specifically relates to an atmospheric resistance passive de-orbiting device and a passive de-orbiting method applied to the last stage of a medium-low orbit rocket. Background technique [0002] With the rapid development of aerospace technology, the space environment is deteriorating day by day, and the ultra-high-speed collision of micrometeoroids and space debris has become an important factor that threatens the safe operation of spacecraft in orbit. When space debris collides with an orbiting spacecraft, the huge collision kinetic energy is enough to cause structural damage, functional failure or even catastrophic accidents of the spacecraft. After the completion of the orbital launch mission, the final stage of the launch vehicle will still operate in the original orbit, and the orbital life may be quite long because the orbital launch mission has been completed, ...

Problems solved by technology

Its disadvantage is that it requires orbital objects to have the ability to control attitude and propulsion

However, because the inflatable structure needs to maintain a certain shape, the material requirements for the inflatable structure are high; moreover, a reliable inflatable system needs to be established, so the structure is very complicated and the implementation is difficult
