The invention discloses a flapping rotor aircraft capable of realizing multi-mode motion based on steering engines, and belongs to the field of micro aircrafts. The multi-mode motion comprises a flapping wing mode and a flapping rotor wing mode. The unmanned aerial vehicle comprises a center shaft rod component, a fuselage component, a flapping component, a torsion component and a wing component. The main control board sends out a control signal to control the motion angle and the rotation speed of the steering engine, so that the steering engine controls flapping wing motion parameters such as a flapping angle and a torsion angle, flapping wing overturning is completed, and conversion between a flapping wing mode and a flapping rotor wing mode is achieved. The characteristics of a step function and a simple harmonic function are combined to describe the twisting motion of the flapping wing, and the defects that when the step function is adopted to describe the twisting angle, simulation calculation is divergent, the inertia force is large, and the service life of a steering engine is shortened in ADAMS simulation and steering engine control are overcome. The unmanned aerial vehicle has more excellent aerodynamic performance, has vertical take-off and landing and hovering performance of a rotor wing flight mode and cruise forward flight performance of a flapping wing flight mode, can meet different flight requirements and has better environment adaptability.

    本发明公开的基于舵机实现多模式运动的扑旋翼飞行器,属于微型飞行器领域。多模式运动包括扑翼模式、扑旋翼模式。本发明包括中轴杆部件、机身部件、拍动部件、扭转部件和机翼部件。通过主控板发出控制信号控制舵机运动角度与转速,使舵机控制拍动角、扭转角等扑翼运动参数,完成扑翼翻转,实现扑翼、扑旋翼模式之间的转换。结合阶跃函数与简谐函数的特点来描述扑翼的扭转运动,克服采用阶跃函数描述扭转角时,在ADAMS仿真与舵机控制中带来仿真计算发散、惯性力大、舵机寿命下降等缺点。本发明具有更优秀的气动力表现,兼备旋翼飞行模式的垂直起降及悬停性能和扑翼飞行模式的巡航前飞性能,能满足不同的飞行需求,具有更好的环境适应能力。
