The invention discloses a morphing wing structure capable of synchronously and continuously changing elongation. The morphing wing structure comprises a synchronous transmission mechanism, a continuous telescopic mechanism, an inner side wing, an outer side wing and a fixed bracket, the synchronous transmission mechanism is used for converting the rotating torque on the symmetry plane of the fuselage into the bilateral synchronous rotating torque in the spanwise direction of the wings; the continuous telescopic mechanism is located in the wing and can drive the wing to complete the continuous variable-elongation action. Variable-elongation mechanism action and aileron steering engine wiring spaces are reserved in the inner side wings; the inner wing inserting piece is a connecting piece of the synchronous transmission mechanism and the inner side wing; the outer wing and the inner wing skin are nested and can continuously translate and slide along the wing spanwise direction under the action of a driving force. The extension lengths of the wings on the two sides can be accurately and synchronously changed according to flight mission requirements, the aerodynamic efficiency of the aircraft in different flight stages is effectively improved, and the risk of flight attitude imbalance caused by asynchronous wing extension length changes is reduced.

    本发明公开了一种可同步连续变展长的变体机翼结构,包括同步传动机构、连续伸缩机构、内侧机翼、外侧机翼及固定支架。同步传动机构将位于机身对称面的转动力矩转换为沿机翼展向的双侧同步转动力矩;连续伸缩机构位于机翼内部,可驱动机翼完成连续变展长动作;内侧机翼预留变展长机构动作及副翼舵机走线空间;内翼插件为同步传动机构与内侧机翼的连接件;外侧机翼与内侧机翼蒙皮嵌套,可在驱动力作用下沿机翼展向做连续平移滑动。本发明能够根据飞行任务需求精确同步地改变两侧机翼展长,有效提高飞行器在不同飞行阶段的气动效率,减少因机翼展长变化不同步导致的飞行姿态失衡风险。
