Space rope net based on constant force tearing belt

Abstract

The invention provides a spatial rope net based on a constant force tearing belt. According to the spatial rope net, partial rope segments, such as rope segments close to the middle of an edge threadrope, of the edge thread rope of the rope net are oppositely folded and overlapped and tied by the constant force tearing belt with the specific strength, that is to say, a fine thread with the certain breaking strength is used for sewing the oppositely-folded rope, and the number of sewing stitches and the density of the stitches are determined by the tearing force strength set by a task. After the rope net is spread to a certain area, the distance between every two adjacent rope nodes tied with the constant force tearing belt is larger than a preset value, the sewing stitches of the constantforce tearing belt start to break at this moment, and further relative separation motion of the rope nodes at the two sides is blocked. After the combined effect of multiple constant force tearing belts, a net opening of the rope net is reduced, the whole rebound speed of a net body can be lowered, the longitudinal motion change of the rope net is small, the valid working time of the rope net iseffectively prolonged, and the valid working distance of the rope net is effectively lengthened.

Description

technical field

[0001] The invention relates to the technical field of space target capture, in particular to a space rope net based on a constant force tearing belt. Background technique

[0002] A large amount of space debris is scattered in the earth's orbit, which has become a major threat to satellite operations and human space activities. In order to reduce the threat of space debris, a variety of active removal methods for space debris have been researched and developed. One of the methods is to use An deployed tether net is launched from an orbiting service tug to capture debris. This method launches a giant rope net to the captured target, wraps the captured target and then pulls it back for recovery or control. Due to the characteristics of low mass, small size, wide capture coverage and high fault tolerance rate, the space flexible rope net system has become one of the main means of active removal of space debris and has great application value.
