The invention discloses a variable sweepback angle mechanism for wings of a variable-wing aircraft. The variable sweepback angle mechanism comprises a mechanism body, and rotating parts rotating around a fixed shaft are symmetrically distributed on the two sides of the body; the steering engine is installed on the mechanism body and connected with the connecting rod through the rudder arm, one end of the connecting rod is connected with the rudder arm, the other end of the connecting rod is connected with the rotating component, rotation of the rudder arm is transmitted to the rotating component through the rudder arm and the connecting rod, and therefore synchronous rotation of the rotating component on the two sides is achieved. The sweepback mechanism of the variable-wing aircraft is arranged at the top of the variable-wing aircraft, the sweepback angle of wings of the upper single-wing unmanned aerial vehicle can be changed, the action can be stopped at any position, and the sweepback angle is kept unchanged. Without exceeding the effective sweepback angle range of the mechanism, any angle change can be realized, so that the variable-wing aircraft obtains the optimal aerodynamic performance under the current flight condition.
本发明公开了可变翼飞行器机翼可变后掠角度机构,包括机构主体,主体两侧对称分布绕定轴转动的旋转部件;舵机安装在机构主体上,舵机通过舵臂与连杆相连,连杆一端连接舵臂,另一端与旋转部件相连,舵臂的转动通过舵臂,舵臂通过连杆将运动传递给旋转部件,从而实现两侧旋转部件的同步转动。可变翼飞行器的后掠机构布置于可变翼飞行器的顶部,可实现上单翼无人机机翼后掠角度的改变,并可以在任意位置停止动作,保持后掠角度不变。在不超过机构有效后掠角度范围内,可以实现任意角度变化,使得可变翼飞行器获得当前飞行条件下的最佳气动性能。
