The invention discloses an empennage-free four-axis flapping wing aircraft, which relates to the technical field of aircrafts, and comprises a main body fuselage and four flapping wing units with thesame structure, which are uniformly distributed along the circumferential direction of the main body fuselage, each flapping wing unit is composed of a motor, a motor shaft gear, a reduction gear set,a connecting rod driving gear, a rocker arm rotating shaft, a crank, a connecting rod, a fixing plate, a rocker and a flexible flapping wing. In the four flapping wing units, the two flapping wing units located on the same straight line incline in the clockwise direction, and the other two flapping wing units incline in the anticlockwise direction at the same angle. The four independently-drivenflapping wing units can generate differential thrust similar to four rotors and can generate pitching and rolling power and yawing moment, and the power type of the aircraft is flexible, comprehensiveand good in maneuverability; a vertical take-off and landing function is achieved, and autonomous take-off and landing can be achieved; the aircraft is simple in structure, high in symmetry, capableof achieving hovering flight, good in wind resistance, relatively easy to control and beneficial to writing and designing of control programs.

    本发明公开了一种无尾翼四轴扑翼飞行器,涉及飞行器技术领域,包括主体机身和沿主体机身周向均布设置的四个结构相同的扑翼单元,扑翼单元由电机、电机轴齿轮、减速齿轮组、连杆驱动齿轮、摇臂转轴、曲柄、连杆、固定板、摇杆和柔性扑动翼构成;四个扑翼单元中,两个位于同一直线的扑翼单元沿顺时针方向倾斜,另两个扑翼单元以相同的角度沿逆时针方向倾斜。本发明四个独立驱动的扑翼单元可以产生类似于四旋翼的差动推力,并且可以产生俯仰、翻滚动力及偏航力矩,飞行器的动力类型灵活、全面,机动性好;具有垂直起降功能,能够实现自主起降;结构简单且对称性高,可实现悬停飞行,具有良好的抗风能力,且控制相对容易,利于控制程序的编写设计。
