The invention aims at solving a problem of low cleaning efficiency in the existing space debris cleaning process, and provides a tethered dragging despinning and deorbiting method for a failure liquid-filled spacecraft. According to the method, a tethered towing system is utilized; the characteristics of liquid shaking and flexible ropes are considered; a system model is established in three-dimensional space; an attitude and orbit integrated control method is designed for the system, the attitude of the space debris is stabilized while the space debris is dragged only through the tugboat thruster. Therefore, the space debris with fuel is effectively and stably dragged to the preset orbit, and large space debris with residual fuel in the space can be efficiently removed.

    本发明的目的是为了解决现有空间碎片清理过程存在清理效率低的问题,提供一种失效充液航天器的绳系拖曳消旋与离轨方法。该方法利用绳系拖曳系统,考虑了液体晃动和柔性绳的特性,在三维空间中建立了系统模型,并针对该系统设计了一种姿轨一体化控制方法,仅通过拖船推进器实现拖曳空间碎片的同时稳定碎片姿态,有效地将带燃料的空间碎片稳定拖曳至预定轨道,能够高效率地清除空间中带有剩余燃料的大型空间碎片。
