The invention discloses a variable sweepback wing and an aircraft. The variable sweepback wing comprises an external connecting rod system based on a multi-connecting-rod mechanism, an internal connecting rod system based on a crank sliding block mechanism and a power assembly. The external connecting rod system is hinged to a fuselage of the aircraft and used for forming a wing body. The internal connecting rod system is hinged to a fuselage of the aircraft and is used for keeping the pose of the wing main body formed by the external connecting rod system; the internal connecting rod system is connected with the external connecting rod system through at least one middle connecting rod, so that the external connecting rod system and the internal connecting rod system form a single-degree-of-freedom plane multi-connecting-rod structure containing a complex hinge; the power assembly can drive the poses of all connecting rods in the external connecting rod system and the internal connecting rod system to change, and the sweepback angle of the wing body is changed. The driving device has the advantages of being simple in driving mode and more uniform in overall stress.

    本发明公开了一种可变后掠翼及飞行器。其中,可变后掠翼包括基于多连杆机构的外部连杆系统、基于曲柄滑块机构的内部连杆系统以及动力组件;外部连杆系统铰接在飞行器的机身上,用于形成机翼主体;内部连杆系统铰接在飞行器的机身上,用于保持外部连杆系统所形成的机翼主体的位姿;内部连杆系统通过至少一个中间连杆与外部连杆系统相连接,使得外部连杆系统和内部连杆系统形成为含复铰的单自由度平面多连杆结构;动力组件可驱使外部连杆系统和内部连杆系统中各连杆的位姿产生变化,并改变机翼主体的后掠角。本发明具有驱动方式简单、整体受力更为均匀的优点。
