The invention relates to a bionic ornithopter capable of changing the attitude of a fuselage. The bionic ornithopter comprises a frame, a motor fixedly connected to the frame and wings symmetrically arranged on the left and right sides of the frame, each wing comprises a crank rocker mechanism hinged to the rack, a four-bar mechanism movably arranged on the rack in a penetrating mode and a flapping long rod. The motor is in driving connection with the crank-rocker mechanism and used for driving the crank-rocker mechanism to rotate; the crank rocker mechanism is connected to the four-bar mechanism and used for driving the four-bar mechanism to do reciprocating swing motion. And the flapping long rod is fixedly connected to the outer side of the four-bar mechanism. The wings adopt double-section type flapping mechanisms, so that resistance caused by upward flapping movement is reduced, lift force caused by downward flapping movement is guaranteed, and the energy utilization rate of the whole aircraft is increased; the bionic flapping-wing air vehicle adopts a sectional structure, and the posture of the vehicle body is variable, so that the flapping-wing air vehicle is more flexible and bionic; various basic movements of birds can be simulated, and actions such as flapping-wing flight, high-altitude sudden stop and steering circling can be realized.
本发明涉及一种可变机身姿态的仿生扑翼飞行器,包括机架、固接于机架的马达和对称设于机架左右两侧的机翼;机翼包括铰接于机架的曲柄摇杆机构、活动穿设于机架的四连杆机构和扑动长杆;马达驱动连接于曲柄摇杆机构,用于驱使曲柄摇杆机构转动;曲柄摇杆机构连接于四连杆机构,用于带动四连杆机构做往复摇摆运动;扑动长杆固接于四连杆机构外侧。机翼采用双段式扑动机构,有利于减少因上扑运动带来的阻力并同时保证下扑运动带来的升力,提高了整机能量利用率;仿生扑翼飞行器采用分段式结构,机身姿态可变,使扑翼飞行器更具灵巧性和仿生性;可模仿鸟类的多种基本运动,能够实现扑翼飞行、高空急停和转向盘旋等动作。
