The invention discloses an active driving type large film unfolding sail device which comprises an upper layer unfolding device, a sail storage device, a lower layer unfolding device, a driving device and a locking device which are sequentially arranged from top to bottom, and the upper layer unfolding device and the lower layer unfolding device are used for achieving extension of a strip-shaped elastic mast so as to drag a film sail to be unfolded; the film sail is stored in the sail storage device; the driving device is used for driving the strip-shaped elastic mast in the unfolding device to unfold; and the locking device is used for locking the unfolding device in the locking state. The active driving type large film unfolding sail device also comprises a baffle device for separating internal devices from the external environment. The active driving type large film unfolding sail device can be used as a mast separation sail for satellite life end-stage deorbit. The active driving type large film unfolding sail device can be used as a solar sail, can be used as a future spacecraft propulsion system, is suitable for a propulsion system of a long-distance deep space exploration spacecraft, and can reduce the mass of the device, simplify the structural design and improve the reliability and stability of the system.

    本发明公开了一种主动驱动式大型薄膜展开帆装置,包括自上而下依次设置的上层展开装置、帆存储装置、下层展开装置、驱动装置、锁紧装置,上层展开装置和下层展开装置用于实现带状弹性桅杆的延伸,进而牵拽薄膜帆的展开;帆存储装置中存储薄膜帆;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。本发明还包括用于将内部装置与外部环境隔离开的档板装置。本发明可作为离桅帆用于卫星寿命末期离轨;也可作为太阳帆,用作未来航天器推进系统,适用于远距离深空探测航天器的推进系统,同时能够减轻装置的质量,简化结构设计,提高系统可靠性和稳定性。
