The invention relates to a passive self-unfolding deorbit sail mechanism with delayed triggering and a control method thereof, and the passive self-unfolding deorbit sail mechanism comprises a deorbit sail container which is connected with a deorbit operation target; the locking device is arranged on the outer surface of the plane I of the deorbit sail container; the timed unlocking device is arranged on the outer surface of the plane I of the deorbiting sail container; the unfolding device comprises an unfolding mechanism, a first spring, a delay trigger device, an elastic tape and a stroke column. According to the passive self-unfolding deorbit sail mechanism with the delayed triggering function and the control method of the passive self-unfolding deorbit sail mechanism, passive timed unlocking can be achieved, the unfolding speed of the sail membrane can be reduced, and the positions and postures of the unfolding mechanism and the sail membrane after unlocking can be controlled; the technical defects of single power supply unlocking, large sail membrane unfolding impact, uncontrollable unfolding process and the like in the existing auxiliary sail deorbit technology are overcome, and the deorbit success rate of the space operation device is improved.

    一种具有延时触发的无源自展开离轨帆机构及其操控方法,包括:离轨帆容器,所述离轨帆容器与离轨操作目标连接;锁紧装置,所述锁紧装置设置在离轨帆容器的平面一外表面;定时解锁装置,所述定时解锁装置设置在离轨帆容器的平面一外表面;展开装置,所述展开装置包括展开机构、弹簧一、延时触发装置、弹性卷尺、行程柱。本发明所述的具有延时触发的无源自展开离轨帆机构及其操控方法,可实现无源定时解锁、减缓帆膜展开速度、以及对解锁后展开机构与帆膜的位置和姿态的控制,弥补了现有辅助帆离轨技术中单一电源解锁、帆膜展开冲击大、展开过程不可控等技术缺点,有利于提高空间操作装置离轨的成功率。
