The invention discloses a telescopic skeleton structure, and provides a wing scheme with foldable internal wing skeletons, continuously variable wingspans and a large wingspan change range for a variable-span aircraft. The telescopic skeleton structure is composed of a steering engine driving device, a wing rib, a sliding rail beam and motion module units. Each motion module unit comprises eight transmission connecting rods and a connecting structure hinged to the connecting rods. The wing ribs are provided with sliding guide rails and lug-shaped bosses. According to the invention, wing extension and retraction can be realized by only one drive, and the unique wing rib design and motion module unit connection mode can enable the common wing rib to translate along the wingspan direction; the parts of the motion module unit are the same in installation and motion mode and equal in motion distance, and the overall stability is guaranteed to a certain extent. The devices are arranged in the airfoil, so that the aerodynamic performance of the aircraft is not influenced in the stretching and retracting process of the airfoil. The space in the wing can be well compressed, control is simple and stable, the structure is simple, and implementation is easy.

    本发明公开了一种可伸缩骨架结构,为可变跨度飞机提供了一种内部机翼骨架可折叠,翼展可连续变化、翼展变化范围大的机翼方案。本发明可伸缩骨架结构由舵机驱动装置、翼肋、滑轨梁和运动模块单元组成,每个运动模块单元包括八根传动连杆和与连杆形成铰接的连接结构;翼肋的设计带有滑动导轨和耳状凸台;本发明只需一个驱动可以实现机翼伸缩,独特的翼肋设计和运动模块单元连接方式能使普通翼肋沿翼展方向做平动;运动模块单元的零件安装、运动方式相同、运动距离相等,一定程度上保证了整体稳定性。以上装置安装位置都在翼面内,不会在机翼伸缩过程中影响飞机的气动性能。本发明能够很好压缩机翼内空间,且控制简单稳定、结构简单,容易实现。
