Method for returning payloads in space station with assistance of unpowered cable

Abstract

The invention relates to a method for returning payloads in a space station with assistance of an unpowered cable, in particular to the method for returning the payloads in the space station. The method provided by the invention is used for solving the problems that requirements for effectively returning the payloads in the space station in time with the low cost cannot be met because the returning cost of the payloads is high, and the high returning cost is caused by that the traditional technology for returning the payload in the space station is subjected to the limitation of a launch window. The method comprises the following main steps of: setting target parameters tn and L of a de-orbiting point; building an expected optimal expansion orbit of the cable; controlling current expansion status parameters of the cable to coincide with excepted values; controlling a tension; controlling a motion orbit of a returning cabin; judging whether the returning cabin arrives at a pre-set position; and expanding, releasing and finishing. The method can be widely applied to returning the payloads in the space station or a low-orbit space-based platform.

Description

technical field [0001] The invention relates to a method for returning a payload of a space station, belonging to the technical field of space vehicle control. Background technique [0002] With the continuous exploration and discovery of space by human beings, the means and technologies of human space exploration have been continuously improved, from using the naked eye to telescopes, and then to space satellites, and human understanding of space has gradually deepened. However, these means and technologies can not meet the needs of contemporary people, so a new space technology and means - space platform, was proposed and realized. From the Soviet "Mir" space station to the current "International Space Station", mankind has achieved a qualitative leap in space-based platform technology. However, with the development of space station technology and the continuous increase of human activities on the space station (space observation and experiments, etc.), a large number of ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the existing space station payload return technology is subject to the limitation of the launch window, the cost of returning the payload is high and cannot meet the timely, effective and low-cost return requirements of the space station payload, and further provides a wireless Space station payload return method assisted by power cable
