The invention discloses a bionic deformable wing unmanned aerial vehicle capable of vertically taking off and landing and a flight attitude control method. The unmanned aerial vehicle comprises a fuselage, wings, rotors and empennages, wings and rotors are arranged on the two sides of the fuselage respectively, and each wing comprises a motor, a framework and a reversing transmission mechanism; the motor and the reversing transmission mechanism are arranged on the fuselage, the reversing transmission mechanism is driven by the motor, the framework is rotationally connected with the fuselage, the framework is driven by the reversing transmission mechanism, folding and unfolding deformation can be achieved in the plane of the fuselage, and ailerons which can be controlled to deflect upwards or downwards are arranged on the framework; the flight attitude control method comprises the steps that when the area of the wings on the folding side is reduced and the sweepback angle is increased, the unmanned aerial vehicle rolls towards the folding side to enter a turning mode, ailerons of the wings on the folding side are controlled to deflect upwards during asymmetric deformation turning of the wings, ailerons on the unfolding side are kept stationary, and the deflection of the ailerons can increase the resistance of the wings on the folding side, so that the unmanned aerial vehicle flies. According to the invention, the flight capability is good, and the flight attitude adjustment is continuous and reliable.
可垂直起降仿生变形翼无人机及飞行姿态控制方法,无人机包含机身、机翼、旋翼和尾翼;机身的两侧分别设置有机翼和旋翼,机翼包含电机、骨架和换向传动机构;电机和换向传动机构布置在机身上,换向传动机构由电机驱动,骨架与机身转动连接,骨架由换向传动机构驱动,可在机身平面内实现折叠和展开变形,骨架上布置有可被控制作向上或向下偏转的副翼;飞行姿态控制方法是,当折叠侧的机翼面积减小后掠角增大会导致无人机向该折叠侧滚转进入转弯模式,在机翼不对称变形转弯时控制折叠侧机翼的副翼向上偏转,而展开侧的副翼保持固定不动,副翼的偏转会增大折叠侧机翼的阻力,使反向偏航现象消除,本发明飞行能力好,飞行姿态调整连续可靠。
