The invention provides a pyrotechnic-mechanical linkage actuation secondary folding control surface which comprises an aircraft cabin, an inner control surface, a middle control surface and an outer control surface which are sequentially arranged from inside to outside, the inner control surface is installed on the aircraft cabin, the middle control surface is connected with the inner control surface through a pyrotechnic folding and unfolding mechanism, the pyrotechnic folding and unfolding mechanism is in transmission connection with the middle control surface, and the outer control surface is installed on the aircraft cabin. The middle control surface can be unfolded or folded in the axial direction of the firer folding and unfolding mechanism, the outer control surface is connected with the middle control surface through the mechanical folding and unfolding mechanism, the mechanical folding and unfolding mechanism is in transmission connection with the outer control surface, and the outer control surface can be unfolded or folded in the axial direction of the mechanical folding and unfolding mechanism. The outer control surface folding and unfolding function is achieved through the mechanical folding and unfolding mechanism, the middle control surface folding and unfolding function is achieved through the fire work folding and unfolding mechanism, locking can be ensured when unfolding is not needed, rapid unfolding can be achieved when unfolding is needed, and the unfolding time and rigidity characteristic requirements are met; and by adopting secondary folding, the storage envelope of the aircraft is reduced, the external space is saved, and the embedded mount or the carrier is convenient to store.
本发明提供了一种火工‑机械联合作动二次折叠舵面,包括由内至外依次设置的:飞行器舱体、内舵面、中舵面以及外舵面,内舵面安装在飞行器舱体上,中舵面通过火工折展机构与内舵面连接,火工折展机构与中舵面传动连接,中舵面能够绕火工折展机构的轴向展开或折叠,外舵面通过机械折展机构与中舵面连接,机械折展机构与外舵面传动连接,外舵面能够绕机械折展机构的轴向展开或折叠。本发明通过机械折展机构实现外舵面折展功能,通过火工折展机构实现中舵面折展功能,在不需要展开时可确保锁紧,在需要展开时可实现快速展开,满足展开时间和刚度特性要求;采用二次折叠减小了飞行器贮存包络,节约外部空间,便于内埋挂载或运载器贮存。
