The invention discloses a timing air injection tethered combination dragging deorbiting method and system based on a winding and unwinding device. The timing air injection tethered combination dragging deorbiting method and system can be applied to a dragging removal task after a space flying net captures a target. For a space control unstable target, after the flying net is used for capturing thetarget, a task satellite pulls a tether once at set intervals to generate tension in a fixed-time air injection mode, so that the target is dragged to deorbit. In a non-air-injection time period, therelative distance between two satellites is close, and the tether may loosen; a threshold value is designed for the loosening degree of the tether; when the loosening degree of the tether exceeds thethreshold value, a tether winding and unwinding device is adopted for winding the tether, and it is guaranteed that the loosening length of the tether is within a certain range; when the relative distance between the two satellites is smaller than the threshold value after multiple times of tether winding, the task satellite jets and moves away, and meanwhile, constant small tension is generatedthrough the constant tension generating capacity of the winding and unwinding device.

    本发明一种基于收放装置的定时喷气绳系组合体拖曳离轨方法及系统,可应用于空间飞网抓捕目标后的拖曳移除任务。对于空间操控失稳目标,在用飞网捕获目标后,通过固定时间喷气的方式,使得任务星每隔一段时间就拉扯一次系绳产生张力,以此来拖曳目标离轨。在非喷气的时间段,两星相对距离接近,系绳可能发生松弛情况。对系绳的松弛程度设计阈值,当系绳松弛超过阈值时,采用系绳收放装置进行收绳操作,保证系绳松弛长度在一定范围内。当经过多次收绳,两星相对距离小于阈值时,任务星喷气远离,同时通过收放装置产生恒定张力的能力产生恒定小张力。
