A Self-Adaptive Penetration Deployment Attachment Device for Space Target Surface Attachment

Abstract

The invention relates to an self-adaptive penetrating and deploying attachment device for attaching to the surface of a space target, comprising: a nose cone, a spear body skeleton, a barb shaft, a first barb, a second barb, a baffle sleeve, a stopper Ejector rod, rear end cover, torsion spring; the tail of the nose cone is installed in the lance body skeleton; the barb shaft is introduced from the pin hole on one side of the lance body skeleton, and passes through the end mounting hole of the second barb and the torsion spring and the end mounting hole of the first barb, and enter the pin hole on the other side of the lance frame; the end with the smaller diameter of the lance frame is inserted into the baffle sleeve and can slide in the baffle sleeve, and the baffle sleeve The lugs at the end of the barrel block the ends of the first barb and the second barb; the limit push rod penetrates through the other end of the baffle sleeve and is installed at the end of the spear body with a smaller diameter, and the rear end cover is installed into the port on the other end of the baffle sleeve. The invention solves the problem of micro-damage capture of large space debris, on-orbit maintenance and off-orbit operation of faulty satellites.

Description

technical field [0001] The invention belongs to the field of on-orbit service and space operation applications such as space debris cleaning, on-orbit maintenance and rescue of faulty satellites, and relates to an adaptive penetration and deployment attachment device. Background technique [0002] Space debris, faulty satellites, abandoned satellites and other space targets are increasing day by day, and the safe operation of space vehicles in orbit is seriously threatened. It will become more and more difficult to deal with traditional active avoidance methods, and will greatly reduce the life of space vehicles; Defense methods can only deal with some types of space targets. On the other hand, large-scale space flight platform facilities will highlight the function of on-orbit maintenance and repair services. For example, to rescue or repair a faulty satellite, it is necessary to complete the task of capturing it at close range. The satellites launched in the early stage p...

AI Technical Summary

Problems solved by technology

The anchor attachment device is suitable for attachment to the hard surface of asteroids in microgravity, and the penetration kinetic energy is relatively large. The deployment mechanism is an active power deployment method, and a pyrotechnic device is required to unlock the action. It is not suitable for the capture of debris, satellites, etc. It will cause penetration and destruction of the target, which violates the original intention of on-orbit rescue and maintenance
