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.
