The invention provides a gas actuating device with a reversible motion structure. The gas actuating device comprises a barrel, a piston, propellants and ignition elements, wherein the propellants and the ignition elements are respectively arranged at the two ends of the barrel, the piston is mounted in the barrel and moves axially along the barrel under pushing of the propellants at the two ends, and wings are driven to be unfolded or folded by acting outwards through a piston rod. By means of the gas actuating device with the reversible motion structure, the internal space is fully utilized, repeated movement of an initiating explosive device is achieved, two-way movement of the piston is achieved through the propellants in front and rear cavities under the conditions of large thrust, good long-term storage performance, simple structure and high reliability, and unfolding and folding of the wings can be achieved.

    本发明提供了一种可逆向运动结构的燃气作动装置,包括筒体、活塞、装药和发火元件,所述的筒体两端分别设置有装药和发火元件,所述的活塞安装在筒体内,在两端装药的推动下沿筒体轴向运动,通过活塞杆对外做功,带动机翼展开或折叠。本发明充分利用了内部空间,实现了火工装置多次运动,在保证大推力、长期贮存性好、结构简单、高可靠的条件下,通过前后腔装药实现活塞的双向运动,能够实现机翼的展开与折叠。
