The invention discloses a miniature double-flapping-wing air vehicle which comprises a middle connecting structure, an attitude control steering engine, a wing root position control mechanism, a frontflapping wing system and a rear flapping wing system, wherein the front flapping wing system and the rear flapping wing system are identical. According to the miniature double-flapping-wing aircraft,the lift force generation is further enhanced by virtue of a double-wing opening-closing mechanism; the flapping frequencies of the front and rear pairs of wings are influenced by changing the rotating speed of the motor so that the two pairs of wings generate front and rear asymmetric lift force to generate pitching control moment; a wing root position control mechanism is controlled by an attitude control steering engine to change the positions of two groups of wing root rods, and the tensioning degree of a flapping wing membrane is changed so that a left wing and a right wing generate different lifting forces to generate rolling control torque. The two sets of wing roots are controlled through one steering engine, the control mechanism is simplified, the control difficulty is reduced,weight reduction is achieved, resources are saved, and besides, pneumatic lift augmentation is achieved through an opening-closing high lift mechanism.
本发明公开了一种微型双扑翼飞行器,包括一个中间连接结构、一个姿态控制舵机、一个翼根位置控制机构和前后两个完全相同的扑翼系统。本发明微型双扑翼飞行器,借助双翼“打开‑合拢”机制进一步增强了升力产生;通过改变电机转速影响前后两对翼拍动频率,从而使两对翼产生前后非对称升力,进而产生俯仰控制力矩;通过一个姿态控制舵机控制翼根位置控制机构改变两组翼翼根杆位置,改变扑翼翼膜的张紧程度,导致左右翼产生不同的升力,产生滚转控制力矩。本发明除采用一个舵机控制两组翼根,简化控制机构,降低控制难度,实现减重,节省资源外,还利用“打开‑合拢”高升力机制实现气动增升。
