The invention discloses a phase-changing quick-return bird-imitating ornithopter with two sections of wings, and relates to the technical field of ornithopters. The problems that an existing flapping wing aircraft is small in flapping angle, symmetrical in upper stroke and lower stroke, low in efficiency and difficult to manufacture, and flapping wing flight is quite threatened due to the existing phase difference are solved. Two inner wing frameworks are symmetrically installed on the two sides of the front end of a fuselage framework correspondingly, two two-section wings are arranged on the outer sides of the two inner wing frameworks correspondingly, the head ends and the tail ends of the inner wings are rotationally connected with the inner wing frameworks and outer wings correspondingly, and the inner wing and the outer wing in each two-section wing are both connected with a single-drive double-crank double-rocker mechanism. An empennage steering mechanism is arranged at the tail end of the fuselage framework, and a steering engine is installed at the tail end of the fuselage framework and connected with the empennage through a steering engine empennage connecting piece. The double-crank and double-rocker structure can ensure that flapping tracks of wings on the two sides of the ornithopter are completely symmetrical, compared with a single-crank and double-rocker mechanism, the problem of phase difference is solved, and the flight safety is improved to a great extent.

    一种变相急回两段翅翼仿鸟扑翼机,它涉及扑翼飞行器技术领域。本发明解决了现有的段扑翼飞行器存在扑动角度小,上下行程对称,效率低,制造困难,存在的相位差对扑翼飞行有相当威胁的问题。本发明的机身构架前端两侧分别对称安装有两个内翅构架,两个内翅构架外侧分别设有两个两段式翅翼,内翅翼首末两端分别与内翅构架和外翅翼转动连接,每个两段式翅翼中的内翅翼和外翅翼均与单驱动双曲柄双摇杆机构连接,机身构架末端设有尾翼转向机构,舵机安装在机身构架末端,舵机通过舵机尾翼连接件与尾翼连接。本发明双曲柄双摇杆结构可以保证扑翼机两侧翅翼的扑动轨迹完全对称,相比于单曲柄双摇杆机构解决了相位差的问题,极大程度上提升了飞行安全性。
