国外航天器在轨捕获技术综述

On-orbit Capture Technology of Spacecraft

论述了国外延寿飞行器设计方案中采用的各种在轨捕获技术,典型捕获机构包括伸缩杆、机械臂、飞网或飞爪等,比较分析了技术复杂性、成本、工程可实现性等问题,最后建议采用通用性好的空间机械臂作为在轨捕获机构,以充分满足在轨延寿、离轨和在轨维修等任务需求。

In this paper, some capture technologies, such as extension rod, mechanical arm, net capture mechanism and tether-gripper mechanism, to be adopted in life extension spacecraft pro- jects of main aerospace countries are described. Comparison and analysis of these mechanisms are given in terms of technical complexity, cost-benefit and engineering feasibility. Finally, to fulfill the task requirement of on-orbit life extension, de-orbit and on-orbit services, a suggestion is presented for developing the space mechanical arm as the main capture mechanism.
