A tether ejection mechanism suitable for passive release of space tether system

Abstract

The invention relates to the technical field of space tethering systems, in particular to a tethered ejection mechanism suitable for passive release of the space tethered system, comprising a base, a plurality of ejection assemblies are fixedly connected above the base, and an ejection body is elastically arranged above the plurality of ejection assemblies The base, between the bottom of the base and the outer side of the projectile base, is provided with a number of snap-release components, a number of snap-release components correspond to the positions of a number of ejection components, and a number of snap-release components are sleeved with a mechanism for releasing the snap-release components. rope assembly. The invention can achieve the effects of avoiding the damage of the tether and enhancing the reliability of the ejection device.

Description

technical field [0001] The present invention relates to the technical field of space tether systems, in particular to a tether ejection mechanism suitable for passive release of the space tether system. Background technique [0002] The space tether system is a new type of space flight system, which has great application potential in space garbage removal, artificial gravity, deep space exploration, etc. The basic structure of the space tether system is a thin and long tether connecting two spacecraft. The total length of the tether can range from hundreds of meters to hundreds of kilometers according to different application scenarios, and the diameter of the tether is about 1-2mm. . When the space tether system is assembled on the ground, the tether should be wound on the rope shaft or stacked, and the system will be launched into orbit and then the internal tether will be released. There are two tether release methods: active release and passive release. Using the power...

Problems solved by technology

Although explosive ejection of pyrotechnics is a relatively mature method, its explosion position is relatively close to the tether of the space tether system, which is likely to cause damage to the surface of the tether or even cause breakage; at the same time, to ensure the stability of ejection, two One or more than two explosive bolts are fixed, and the increase in the number also reduces the reliability of the ejection method. Therefore, it is necessary to design an ejection mechanism suitable for the space tether system.
