The invention discloses a multilayer micro
bionics flapping aerocraft, and belongs to the field of
mechanical design. The multilayer micro
bionics flapping aerocraft comprises double-layer double-
crank rocker mechanisms, a driving mechanism and a flexible wing mechanism. The driving mechanism produces driving force and transmits the driving force to the double-layer double-
crank rocker mechanisms.The double-layer double-
crank rocker mechanisms produce corresponding
flapping trajectories and overturn actively to drive the flexible wing mechanism connected with the double-layer double-crank rocker mechanisms, so that the function of simultaneously conducting of flapping and turnover movement is achieved. By setting parameters such as the lengths of rockers, the lengths of cranks and the lengths of connecting rods on the upper and lower
layers of mechanisms, the
phase difference between the two
layers of double-crank rocker mechanisms during moving is changed, so that flexible wings rotate to produce the
angle of attack while the flexible wings flap; meanwhile, the flexible wings produce
large deformation to form passive overturning, so that it is ensured that a large lift force is produced. The multilayer micro
bionics flapping aerocraft has the functions of simultaneously achieving flapping and twisting the wings and the like, and has the characteristics of being compact in structure, small and exquisite in size, very low in
mass, flexible in mechanism and the like.
