The invention provides a telescopic rigid-flexible coupling skin mechanism. The telescopic rigid-flexible coupling skin mechanism comprises multiple stages of sliding rings capable of sliding relatively and a locking mechanism. The slip ring is provided with a rigid slip layer which is used for filling the extension amount when the multi-stage slip ring axially moves and unfolds so as to resist external load and heat; a flexible stretchable sealing layer is arranged below the rigid sliding layer and is used for deforming along with the rigid sliding layer, so that a sealing state is kept in the whole deformation process; the locking mechanism comprises a locking bolt, a locking nut and a locking cylindrical boss. The sliding rings are connected through the locking bolt and the locking nut. The locking cylindrical bosses are connected to the adjacent sliding rings and used for limiting the minimum displacement distance of the adjacent sliding rings so as to limit the minimum compression position of the mechanism. And a large hole for preventing interference with the locking bolt is dug in the sliding ring. The sliding principle is adopted, it can be guaranteed that the morphing aircraft can fly in the optimal pneumatic state, only one degree of freedom exists, control is easy, a locking mechanism is arranged, and performance is reliable.
本发明提供了一种可伸缩刚柔耦合蒙皮机构,包括多级可相对滑动的滑移环,以及锁定机构;滑移环设有刚性滑移层,用于在多级滑移环轴向运动展开时填补伸展量,用以抵御外载荷和热量;刚性滑移层下面设有柔性可拉伸密封层,用于随刚性滑移层变形,使整个变形过程中保持密封的状态;锁定机构包括锁定螺栓、锁定螺母、锁定圆柱凸台,各级滑移环通过锁定螺栓及锁定螺母连接;锁定圆柱凸台连接在相邻滑移环上,用于限制相邻滑移环最小位移距离,以限制机构的最小压缩位置;所述滑移环挖有防止与锁定螺栓干涉的大孔。本发明采用滑移的原理,能够保证变体飞行器可以在气动最优状态下飞行,只有一个自由度,控制简单,且带有锁定机构,性能可靠。
