The invention belongs to the field of spacecraft deorbiting, and particularly relates to a brake sail deorbiting device applied to a vertical satellite. The device includes: a sail storage device, a driving device, an unfolding device and a locking device which are sequentially arranged from top to bottom. A film sail is stored in the sail storage device; the unfolding device comprises four strip-shaped elastic masts and a mast center shaft, the extension sections of the strip-shaped elastic masts are connected with the film sail, and the fixed ends of the strip-shaped elastic masts are woundon the mast center shaft; the four wound strip-shaped elastic masts are unfolded to drive the thin film sail connected with the elastic masts to be unfolded; the driving device is used for driving thestrip-shaped elastic mast in the unfolding device to be unfolded; and the locking device is used for locking the unfolding device in a locking state. The deorbiting device provided by the invention is suitable for deorbiting cubesat running on medium and low orbits, and solves the problem that normal work of other satellites is affected by space debris due to the fact that part of cubesat cannotbe deorbited within a specified time after completing a task.

    本发明属于航天器离轨领域,具体涉及一种应用于立卫星的制动帆离轨装置。包括自上而下依次设置的帆存储装置、驱动装置、展开装置和锁紧装置;帆存储装置中存储薄膜帆;展开装置包括四根带状弹性桅杆和桅杆中心轴,带状弹性桅杆的延伸段和薄膜帆连接,带状弹性桅杆的固定端缠绕在桅杆中心轴上;缠绕的四根带状弹性桅杆展开,从而带动与其连接的薄膜帆展开;驱动装置用于驱动展开装置中带状弹性桅杆的展开;锁紧装置用于锁紧状态时展开装置的锁紧。本发明提供的离轨装置,适用于运行于中低轨道的立方星的离轨,解决了部分立方星在完成任务后无法在规定时间内离轨从而成为空间碎片影响其他卫星正常工作的问题。
