The invention belongs to the technical field of aircraft structure design, and particularly relates to a centroid-adjustable connecting rod type variable swept wing structure and an aircraft. A connecting rod mechanism is arranged between the fuselage and the wings on the two sides, one end of the connecting rod mechanism is rotationally connected to the wing framework, the other end of the connecting rod mechanism is rotationally connected to the fuselage frame beam, the connecting rod mechanism is driven by a driver, and then the sweepback angle change of the wings is achieved. The variable sweepback wing has the characteristic that the centroid position is adjustable, the problems that when the sweepback angle of an existing variable sweepback wing is changed, the aerodynamic center position is greatly changed, and consequently the flight stability and the control difficulty are increased can be solved, and the wide application prospect is achieved.

    本发明属于飞行器结构设计技术领域,具体涉及一种形心可调的连杆式变后掠翼结构及飞行器;在机身与两侧机翼之间布置连杆机构,所述连杆机构一端转动连接至机翼骨架上,另一端转动连接至机身框梁上,所述连杆构通过驱动器实现驱动,进而实现机翼后掠角变化。本发明具有形心位置可调的变后掠翼特性,可解决现有变后掠翼后掠角发生变化时气动中心位置大幅变化引起飞行稳定性和控制难度增加等问题,具有宽阔的应用前景。
