摘要： 如何清除轨道上日益增多的废弃目标已成为国内外航天活动无法回避的现实问题和迫切需解决的问题。针对低轨道大型废弃目标回收问题，基于天基回收技术的概念，提出了一种新型组合式柔性捕获回收方案。使用空间绳网捕获废弃目标后通过充气式增阻离轨方式进行被动离轨，再利用充气式进入减速技术 (inflatable entry decelerator technology, IRDT)进行再入、减速并返回地面。根据方案建立了动力学模型，开展了仿真计算分析。仿真结果表明，该方案技术可行，可用于未来空间目标的捕获和回收。

Abstract:

The increasing space debris has a great influence on space activity. It has already been an actual problem how to deal with the threat of space debris to spacecraft. Aiming at the problem of low-orbit large-scale useless target recovery, a new combined flexible capture and recovery scheme was proposed based on the concept of space-based recovery technology. A space net was projected to capture the abandoned target which was passively de-orbited through the inflatable dragincreasing method. Then IRDT was utilized in reentry, deceleration and return to the ground. A dynamic model was established, and simulation calculation analysis was carried out. The simulation results show that the scheme is technically feasible and can be used for the capture and recovery of future space targets.
