An active and passive flexible bird-imitating flapping wing aircraft comprises a driving mechanism, a rack, an empennage mechanism and two wings, the driving mechanism is installed on the rack to drive the two wings to flap up and down, and the empennage mechanism is arranged at the tail of the rack to adjust the flight attitude of the aircraft; the unmanned aerial vehicle further comprises a passive flexible mechanism, and each wing comprises an inner wing and an outer wing. The inner wing comprises an inner wing rod, an inner wing supporting rod and two inner wing plates; the outer wing comprises an outer wing rod and a plurality of outer wing plates, the two inner wing plates are connected with the inner wing supporting rod through the inner wing rod, the inner wing plate on the inner side is fixed to the rack, the outer wing plates are fixed to the outer wing rod, and the inner wing rod is connected with the outer wing rod through a passive flexible mechanism; the passive flexible mechanism is of a variable-rigidity structure, and the variable-rigidity structure is formed by connecting a plurality of connecting rods and flexible hinges connecting the adjacent connecting rods in series. The device is stable and reliable in structure, the problem that the flapping wing action of the aircraft is relatively fixed can be solved, and the self-adjusting capacity to environment changes is improved.
