The invention provides a variable sweepback wing folding and unfolding mechanism and method for a small patrol aircraft, an upper wing of a wing is mounted at the upper end of a central shaft positioned on the rear side of a nose, the root of a lower wing is rotatably connected to the lower end of the central shaft, a rocker arm is fixedly mounted at the lower end of the central shaft, and the rocker arm and the wing root are respectively connected with a sliding block of a guide rail sliding block assembly through connecting rods; the sliding blocks can slide on the guide rails under the action of the springs to drive the connecting rods and the rocker arms to rotate, so that the wings rotate around the shafts to unfold. An electric actuating cylinder is mounted below the guide rail sliding block assembly and can be locked with a spring pin mounted at the bottom of a sliding block in a matched manner, and when the sweepback angle of the wings needs to be increased, a flight control system controls the actuating end of the electric actuating cylinder to extend backwards along the guide rail, pushes the sliding block to move and drives a connecting rod to drive the upper wing and the lower wing to rotate backwards; the patrol flight device can perform cruising flight for a long time by adopting a small sweepback angle during cruising flight, and performs killing attack on a target by adopting a large sweepback angle express attack, so that the combat effectiveness is improved.
本发明提供用于小型巡飞器的可变后掠角机翼折叠与展开机构及方法,机翼的上翼安装在位于机头后侧的中心轴上端,下翼根部转动连接在中心轴下端,中心轴下端固定安装摇臂,摇臂和翼根分别通过连杆与导轨滑块组件的滑块连接,滑块能够在导轨上弹簧作用下滑动,带动连杆和摇臂转动,使得机翼绕轴转动展开。导轨滑块组件下方装有电作动筒,能够与安装在滑块底部的弹簧销配合锁定,当需要增大机翼后掠角时,飞行控制系统控制电作动筒作动端沿导轨向后伸出,推动滑块运动,带动连杆驱动上翼和下翼向后转动,使巡飞器能够在巡航飞行时采用小后掠角长时间巡航飞行,在对目标进行杀伤攻击采用大后掠角快递攻击,提高了作战效能。
