After a cable rotating system is connected to a spacecraft, the linear speed is reduced through outward movement, and the method is very ideal. However, in the outward moving process, due to the factthat the angular momentum is reduced, the angular speed becomes very low and even lower than 0.001 rad/s, and the period is very long. Moreover, outward movement to the position 3-6 times of the buttjoint radius cannot be realized before 10-20 or more autorotation periods, the process takes tens of minutes or more, and is too long. The invention provides a free outward moving method which can greatly reduce the time consumed in the outward moving process. By means of the method, the variable-diameter rope can be moved outwards to the position 3-6 times of the butt joint radius and withdrawn within one period.
转缆系统接上宇宙飞船后,通过外移来降低线速度,是一种非常理想的办法。但是外移过程中由于角动量降低,角速度变得非常慢,甚至低于0.001rad/s,周期很长。而且,要进行10‑20个以上自转周期才能够外移至3‑6倍对接半径处,这个过程要花费数十分钟以上,时间过长。本发明提供了一种自由外移方法,他能够大大降低外移过程的耗时。利用这种方法,不到一个周期就能够外移至3‑6倍对接半径处并且收回变径绳。
